HUMAN GLUCAGON-LIKE PEPTIDE-1 MIMICS AND THEIR USE IN THE TREATMENT
OF DIABETES AND RELATED CONDITIONS
Abstract
The present invention provides novel human glucagon-like
peptide-1 (GLP-1) peptide mimics that mimic the biological activity
of the native GLP-1 peptide and thus are useful for the treatment
or prevention of diseases or disorders associated with GLP
activity. Further, the present invention provides novel, chemically
modified peptides that not only stimulate insulin secretion in type
II diabetics, but also produce other beneficial insulinotropic
responses. These synthetic peptide GLP-1 mimics exhibit increased
stability to proteolytic cleavage making them ideal therapeutic
candidates for oral or parenteral administration.

FIELD OF THE INVENTION
[0002] The present invention provides novel human glucagon-like
peptide-1 (GLP-1) peptide mimics, which duplicate the biological
activity of the native peptide, exhibit increased stability to
proteolytic cleavage as compared to GLP-1 native sequences, and
thus are useful for the amelioration of the diabetic condition.
BACKGROUND OF THE INVENTION
[0003] GLP-1 is an important gut hormone with regulatory function
in glucose metabolism and gastrointestinal secretion and
metabolism. Human GLP-1 is a 30 amino acid residue peptide
originating from preproglucagon, which is synthesized for example,
in the L-cells in the distal ileum, in the pancreas and in the
brain. Processing of preproglucagon to yield GLP-1 (7-36) amide and
GLP-2 occurs mainly in the L-cells. GLP-1 is normally secreted in
response to food intake; in particular carbohydrates and lipids
stimulate GLP-1 secretion. GLP-1 has been identified as a very
potent and efficacious stimulator for insulin release. GLP-1 lowers
glucagon concentration, slows gastric emptying, stimulates insulin
biosynthesis and enhances insulin sensitivity (Nauck, 1997, Horm.
Metab. Res. 47:1253-1258). GLP-1 also enhances the ability of the
B-cells to sense and respond to glucose in subjects with impaired
glucose tolerance (Byrne, Eur. J. Clin. Invest., 28:72-78, 1998).
The insulinotropic effect of GLP-1 in humans increases the rate of
glucose metabolism partly due to increased insulin levels and
partly due to enhanced insulin sensitivity (D'Alessio, Eur. J.
Clin. Invest., 28:72-78, 1994). The above stated pharmacological
properties of GLP-1 make it a highly desirable therapeutic agent
for the treatment of type-II diabetes. Additionally, recent studies
have shown that infusions of slightly supraphysiological amounts of
GLP-1 significantly enhance satiety and reduce food intake in
normal subjects (Flint, A., Raben, A., Astrup, A. and Holst, J. J.,
J. Clin. Invest, 101:515-520, 1998; Gutswiller, J. P., Goke, B.,
Drewe, J., Hildebrand, P., Ketterer, S., Handschin, D.,
Winterhaider, R., Conen, D and Beglinger, C., Gut, 44:81-86,
1999;). The effect on food intake and satiety has also been
reported to be preserved in obese subjects (Naslund, E., Barkeling,
B., King, N., Gutniak, M., Blundell, J. E., Holst, J. J., Rossner,
S., and Hellstrom, P. M., Int. J. Obes. Relat. Metab. Disord.,
23:304-311, 1999). In the above-cited studies a pronounced effect
of GLP-1 on gastric emptying was also suspected to occur. Gastric
emptying results in post-prandial glucose excursions. It has also
been shown that in addition to stimulation of insulin secretion,
GLP-1 stimulates the expression of the transcription factor IDX-1
while stimulating B-cell neogenesis and may thereby be an effective
treatment and/or preventive agent for diabetes (Stoffers, D. A.,
Kieffer, T. J. Hussain, M. A., Drucker, D. J., Bonner-Weir, S.,
Habener, J. F. and Egan, J. M. Diabetes, 40:741-748, 2000). GLP-1
has also been shown to inhibit gastric acid secretion (Wettergren,
A., Schjoldager, B., Mortensen, P. E., Myhre, J., Christiansen, J.,
and Holst, J. J., Dig. Dis. Sci., 38:665-673, 1993), which may
provide protection against gastric ulcers.
[0004] GLP-1 is an incretin hormone, for example, an intestinal
hormone that enhances meal-induced insulin secretion (Holst, J. J.,
Curr. Med. Chem., 6:1005-1017, 1999). It is a product of the
glucagon gene encoding proglucagon. This gene is expressed not only
in the A-cells of the pancreas but also in the endocrine L-cells of
the intestinal mucosa. Proglucagon is a peptide (protein)
containing 160 amino acids. Further processing of proglucagon
results in the generation of a) glucagon, b) an N-terminal,
presumably inactive fragment, and c) a large C-terminal fragment
commonly referred as "the major proglucagon fragment". This
fragment is considered to be biologically inactive. Even though
this fragment is present in both pancreas and in the L-cells of the
gut, it is only in the intestines the breakdown products of the
"the major proglucagon fragment" resulting in two highly homologous
peptides commonly referred as GLP-1 and GLP-2 are observed. These
two peptides have important biological activities. As such, the
amino acid sequence of GLP-1, which is present in the L-cells, is
identical to the 78-107 portion of proglucagon.
[0005] The present invention provides novel GLP-1 peptide mimics
that duplicate the biological activity of the native peptide and
thus are useful for the amelioration of the diabetic condition.
[0006] Presently, therapy involving the use of GLP-1-type molecules
has presented a significant problem because the serum half-life of
such peptides is quite short. For example, GLP-1 (7-37) has a serum
half-life of only 3 to 5 minutes. Thus there exists a critical need
for biologically active GLP-1 mimics that possess extended
pharmacodynamic profiles.

and/or lower triglycerides and/or lower total cholesterol and/or
other known mechanisms for therapeutically treating lipid
disorders.
[0085] An administration of a therapeutic agent of the invention
includes administration of a therapeutically effective amount of
the agent of the invention. The term "therapeutically effective
amount" as used herein refers to an amount of a therapeutic agent
to treat or prevent a condition treatable by administration of a
composition of the invention. That amount is the amount sufficient
to exhibit a detectable therapeutic or preventative or ameliorative
effect. The effect may include, for example, treatment or
prevention of the conditions listed herein. The precise effective
amount for a subject will depend upon the subject's size and
health, the nature and extent of the condition being treated,
recommendations of the treating physician, and the therapeutics or
combination of therapeutics selected for administration. Thus, it
is not useful to specify an exact effective amount in advance.
[0086] The peptides and analogs thereof described herein may be
produced by chemical synthesis using various solid-phase techniques
such as those described in G. Barany and R. B. Merrifield, "The
Peptides: Analysis, Synthesis, Biology"; Volume 2-"Special Methods
in Peptide Synthesis, Part A", pp. 3-284, E. Gross and J.
Meienhofer, Eds., Academic Press, New York, 1980; and in J. M.
Stewart and J. D. Young, "Solid-Phase Peptide Synthesis", 2.sup.nd
Ed., Pierce Chemical Co., Rockford, Ill., 1984. The preferred
strategy for use in this invention is based on the Fmoc
(9-Fluorenylmethylmethyloxycarbonyl) group for temporary protection
of the .alpha.-amino group, in combination with the tert-butyl
group for temporary protection of the amino acid side chains (see
for example E. Atherton and R. C. Sheppard, "The
Fluorenylmethoxycarbonyl Amino Protecting Group", in "The Peptides:
Analysis, Synthesis, Biology"; Volume 9--"Special Methods in
Peptide Synthesis, Part C", pp. 1-38, S. Undenfriend and J.
Meienhofer, Eds., Academic Press, San Diego, 1987.
[0087] The peptides can be synthesized in a stepwise manner on an
insoluble polymer support (also referred to as "resin") starting
from the C-terminus of the peptide. A synthesis is begun by
appending the C-terminal amino acid of the peptide to the resin
through formation of an amide or ester linkage. This allows the
eventual release of the resulting peptide as a C-terminal amide or
carboxylic acid, respectively. Alternatively, in cases where a
C-terminal amino alcohol is present, the C-terminal residue may be
attached to 2-Methoxy-4-alkoxybenzyl alcohol resin (SASRIN.TM.,
Bachem Bioscience, Inc., King of Prussia, Pa.) as described herein
and, after completion of the peptide sequence assembly, the
resulting peptide alcohol is released with LiBH.sub.4 in THF (see
J. M. Stewart and J. D. Young, supra, p. 92).
[0088] The C-terminal amino acid and all other amino acids used in
the synthesis are required to have their .alpha.-amino groups and
side chain functionalities (if present) differentially protected
such that the .alpha.-amino protecting group may be selectively
removed during the synthesis. The coupling of an amino acid is
performed by activation of its carboxyl group as an active ester
and reaction thereof with the unblocked .alpha.-amino group of the
N-terminal amino acid appended to the resin. The sequence of
.alpha.-amino group deprotection and coupling is repeated until the
entire peptide sequence is assembled. The peptide is then released
from the resin with concomitant deprotection of the side chain
functionalities, usually in the presence of appropriate scavengers
to limit side reactions. The resulting peptide is finally purified
by reverse phase HPLC.
[0089] The synthesis of the peptidyl-resins required as precursors
to the final peptides utilizes commercially available cross-linked
polystyrene polymer resins (Novabiochem, San Diego, Calif.).
Preferred for use in this invention are
4-(2',4'-dimethoxyphenyl-Fmoc-aminomethyl)-phenoxyacetyl-p-methyl
benzhydrylamine resin (Rink amide MBHA resin) or p-benzyloxybenzyl
alcohol resin (HMP resin) to which the C-terminal amino acid may or
may not be already attached. If the C-terminal amino acid is not
attached, its attachment may be achieved by DMAP-catalyzed
esterification with the O-acylisourea or the HOAT active ester of
the Fmoc-protected amino acid formed by its reaction with DIC or
DIC/HOAT, respectively. Coupling of the subsequent amino acids can
be accomplished using HOBT or HOAT active esters produced from
DIC/HOBT or DIC/HOAT, respectively.
[0090] The syntheses of the 11-mer peptide analogs described herein
can be carried out by using a peptide synthesizer, such as an
Advanced Chemtech Multiple Peptide Synthesizer (MPS396) or an
Applied Biosystems Inc. peptide synthesizer (ABI 433A). If the
MPS396 was used, up to 96 peptides were simultaneously synthesized.
If the ABI 433A synthesizer was used, individual peptides were
synthesized sequentially. In both cases the stepwise solid phase
peptide synthesis was carried out utilizing the Fmoc/t-butyl
protection strategy described herein. The non-natural
non-commercial amino acids present at position 11 and at position
10 were incorporated into the peptide chain in one of two methods.
In the first approach a Boc- or Fmoc-protected non-natural amino
acid was prepared in solution using appropriate organic synthetic
procedures. The resulting derivative was then used in the step-wise
synthesis of the peptide. Alternatively the required nonnatural
amino acid was built on the resin directly using synthetic organic
chemistry procedures. When a nonnatural non-commercial amino acid
was needed for incorporation at position X.sub.aa6 or at any other
X.sub.aa position as needed, the required Fmoc-protected nonnatural
amino acid was synthesized in solution. Such a derivative was then
used in stepwise solid phase peptide synthesis.
[0091] Preferred for use in this invention are the Fmoc amino acids
derivatives shown below.

[0094] The peptidyl-resin precursors for their respective peptides
may be cleaved and deprotected using any of the standard procedures
described in the literature (see, for example, D. S. King et al.
Int. J. Peptide Protein Res. 36, 1990, 255-266). A preferred method
for use in this invention is the use of TFA in the presence of
water and TIS as scavengers. Typically, the peptidyl-resin is
stirred in TFA/water/TIS (94:3:3, v:v:v; 1 mL/100 mg of peptidyl
resin) for 1.5-2 hrs at room temperature. The spent resin is then
filtered off and the TFA solution is concentrated or dried under
reduced pressure. The resulting crude peptide is either
precipitated and washed with Et.sub.2O, or is redissolved directly
into DMSO or 50% aqueous acetic acid for purification by
preparative HPLC.
[0095] Peptides with the desired purity can be obtained by
purification using preparative HPLC, for example, on a Waters Model
4000 or a Shimadzu Model LC-8A liquid chromatograph. The solution
of crude peptide is injected into a YMC S5 ODS (20.times.100 mm)
column and eluted with a linear gradient of MeCN in water, both
buffered with 0.1% TFA, using a flow rate of 14-20 mL/min with
effluent monitoring by UV absorbance at 220 nm. The structures of
the purified peptides can be confirmed by electro-spray MS
analysis.

[0097] Those skilled in the art of peptide chemistry are aware that
amino acid residues occur as both D and L isomers, and that the
instant invention contemplates the use of either or a mixture of
isomers for amino acid residues incorporated in the synthesis of
the peptides described herein.
[0098] In one embodiment, the present invention provides a method
of making a polypeptide of formula ##STR7## that mimics the
activity of a polypeptide receptor agonist having a message
sequence and an address sequence. In this embodiment, the address
sequence of the polypeptide confers the ability of a polypeptide to
bind to a receptor and the message sequence is capable of inducing
receptor mediated signal transduction upon binding of the
polypeptide to the receptor. The method of making the polypeptide
comprises replacing the message sequence of a polypeptide receptor
agonist with Y and Z wherein Y and Z are amino acid residues;
[0099] wherein one of the substitutions at the alpha-carbon atoms
of Y and Z may each independently be substituted with a primary
substituent group selected from the group consisting of hydrogen,
alkyl, cycloalkyl, cycloalkylalkyl, heterocyclylalkyl, arylalkyl
and heteroarylalkyl, heterocyclylalkyl said primary substituent
optionally being substituted with a secondary substituent selected
from a cycloalkyl, heterocyclyl, aryl or heteroaryl group; any of
said primary or secondary substituents may further be substituted
with one or more of, hydrogen, alkyl, cycloalkyl, arylalkyl, aryl,
heterocyclyl, heteroaryl, alkenyl, alkynyl, halo, hydroxy,
mercapto, nitro, cyano, amino, acylamino, azido, guanidino,
amidino, carboxyl, carboxamido, carboxamido alkyl, formyl, acyl,
carboxyl alkyl, alkoxy, aryloxy, arylalkyloxy, heteroaryloxy,
heterocycleoxy, acyloxy, mercapto, mercapto alkyl, mercaptoaryl,
mercapto acyl, halo, cyano, nitro, azido, amino, guanidino alkyl,
guanidino acyl, sulfonic, sulfonamido, alkyl sulfonyl, aryl
sulfonyl or phosphonic group; wherein, the primary or secondary
substitutents may optionally be bridged by covalent bonds to form
one or more fused cyclic or heterocyclic systems with each
other;
[0100] wherein, the other substitution at the alpha-carbon of Y may
be substituted with hydrogen, alkyl, aminoalkyl, hydroxyalkyl or
carboxyalkyl;
[0101] wherein, the other substitution at the alpha-carbon of Z may
be substituted with hydrogen, alkyl, aminoalkyl, hydroxyalkyl or
carboxyalkyl.
[0102] In a preferred embodiment, the present invention provides a
method of making a polypeptide that mimics the activity of an
endogenous polypeptide receptor agonist. In another preferred
embodiment, the polypeptide receptor agonist is GLP-1. In another
aspect, the method of making the polypeptide further comprises
replacing the message sequence of the polypeptide with a variant
message sequence capable of inducing receptor mediated signal
transduction. Variant message sequences can be made by replacing or
modifying one or more amino acid residues of a polypeptide receptor
agonist message sequence.
EXAMPLE 1
Simultaneous Solid Phase Peptide Synthesis of GLP-1 11-Mer Peptide
Mimics
[0103] Dipeptidyl resin, containing non-natural non-commercial
amino acid residues at positions 10 and 11, was prepared using the
following manual procedure in a batch-wise mode before continuing
peptide chain elongation utilizing the automated simultaneous
synthesis protocol on the MPS-396 peptide synthesizer. The
synthesis of the N.alpha.-Fmoc-protected biphenylalanine
derivatives used in the manual couplings is described in Examples
8-10.
[0104] An amount of
4-(2',4'-dimethoxyphenyl-Fmoc-aminomethyl)-phenoxyacetyl-p-methyl
benzhydrylamine resin (Rink amide MBHA resin; loading: 0.5 mmol/g)
sufficient to synthesize several 1'-mer analogs, was swelled by
washing with DMF (4.times.10 mL/g, 5 minutes). The Fmoc group was
then removed using two treatments, 3 and 18 minutes each
respectively, with 20% piperidine in DMF (10 mL/g). The resin was
washed with DMF (4.times.10 mL/g) and NMP (4.times.10 mL/g). A 0.5
M solution of Fmoc-L-biphenylalanine-OH (2.0 eq.), or analog
thereof, and HOAt (2.0 eq.) in NMP was added to the resin, followed
by a 1.0 M solution of DIC (2.05 eq.) in NMP. The resin was then
shaken or vortexed for 16-24 hours. Coupling completion was
monitored using a qualitative ninhydrin test. The resin was
drained, washed with NMP (3.times.10 mL/g) and DMF (3.times.10
mL/g), and treated twice, 5 and 20 minutes each respectively, with
20% acetic anhydride in DMF (8 mL/g). After DMF washes (4.times.10
mL/g), a second manual coupling cycle was then performed as
described above, starting from the removal of the Fmoc group with
20% piperidine in DMF, and using either the same or a different
Fmoc-protected biphenylalanine analog in the coupling step. This
synthesis scheme produced the desired Fmoc-protected
dipeptidyl-Rink amide MBHA resin.
[0105] Similar dipeptidyl resins were also obtained by another
procedure, described in Examples 5-7, using solid phase Suzuki
condensation reactions.
[0106] Such dipeptidyl-resins required for the synthesis of a set
of designed analogs were then used in the automated MPS synthesis
of up to 96 peptides per run in the following manner. The
dipeptidyl-resins were loaded as suspensions in dichloromethane/DMF
(60:40) into the 96-well reactor of an Advanced ChemTech MPS 396
synthesizer in volumes corresponding to 0.01-0.025 mmol (20-50 mg)
of resin per reactor well. The reactor was placed on the instrument
and drained. The wells were then washed with DMF (0.5-1.0 mL,
3.times.2 min) and subjected to the number of automated coupling
cycles required to assemble the respective peptide sequences as
determined by the pre-programmed sequence synthesis table. The
detailed stepwise synthesis protocol used for a typical 0.01
mmol/well simultaneous synthesis of 96 compounds is described
below. This protocol was adapted for the simultaneous synthesis of
arrays of analogs ranging from 12 to 96 per individual run. The
general synthesis protocol is depicted in Scheme I. ##STR8##
[0107] Prior to starting the synthesis, the following reagent
solutions were prepared and placed on the instrument as required:
1.5 M (15%) piperidine in DMF; 0.5 M DIEA in NMP; 0.36 M DIC in
NMP; 1 M (10%) acetic anhydride in DMF. The required Fmoc-protected
amino acids were prepared as 0.36 M solutions in 0.36 M HOAt/NMP
and placed into the appropriate positions in the 32-position amino
acid rack.
[0108] The Fmoc-protected dipeptidyl-resin prepared above was
deprotected by treating with 1.5 M (15%) piperidine in DMF (0.6 mL;
1.times.3 minutes; 1.times.18 minutes). The resin was then washed
with DMF (4.times.0.5 mL), DMF/EtOH (80:20) (1.times.0.5 mL) and
NMP (3.times.0.5 mL).
[0109] Coupling of the next amino acid residue, typically
Fmoc-Asp(OtBu)-OH or another Fmoc-amino acid with appropriate
orthogonal protection if required, was carried out by automated
addition of a 0.36 M solution of the appropriate Fmoc-amino acid
(0.072 mmol, 7.2 eq.) and HOAt (7.2 eq.) in NMP (0.2 mL) to all 96
wells. This was followed by addition to all 96 wells of a 0.36 M
solution of DIC (0.072 mmol, 7.2 eq.) in NMP (0.2 mL). The coupling
was allowed to proceed for 2 hrs. After reactor draining by
nitrogen pressure (3-5 psi) and washing the wells with NMP
(1.times.0.5 mL), the coupling was repeated as described above. At
the end of the coupling cycle, the wells were treated with 1M
acetic anhydride in DMF (1.times.0.5 mL, 30 min.) and finally
washed with DMF (3.times.0.5 mL).
[0110] The next coupling cycle started with the removal of the Fmoc
group as described above, and involved the coupling of either
Fmoc-Ser(tBu)-OH or of a different Fmoc-amino acid as required by
the sequence substitutions desired at this position. The coupling
was carried out in a manner identical to that described for
Fmoc-Asp(OtBu)-OH. The next coupling step was carried out in the
same way to incorporate either Fmoc-Thr(tBu)-OH or any of the other
selected Fmoc-amino acids into this sequence position as
required.
[0111] The next Fmoc-amino acid (for example Fmoc-Phe-OH) was
coupled as described above. For sequences requiring incorporation
of a novel non-commercially available aromatic or non-aromatic
amino acid analog at this step, the coupling was modified as
follows: after Fmoc deprotection in the usual manner, the
Fmoc-amino acid (5 eq.) and HOAt (5 eq.) were added manually as a
0.36 M solution in NMP (0.139 mL). The 0.36 M solution of DIC in
NMP (0.139 mL) was then added by the instrument and the coupling
was allowed to proceed for 16-24 hrs. The coupling was not repeated
in this case. After the usual post-coupling washes, the
peptidyl-resins were capped with acetic anhydride as described.
[0112] The next coupling step involved either Fmoc-Thr(tBu)-OH or
substitution analogs as required by sequence replacements at this
position. The coupling was performed as described for the initial
MPS coupling of Fmoc-Asp(OtBu)-OH and its analogs. This identical
coupling protocol was repeated four additional times in order to
complete the sequence assembly of the desired 96 11-mer peptide
analogs. For the coupling of commercially and non-commercially
available non-natural amino acids needed at a certain sequence
position, a single coupling protocol similar to that described
above for the novel amino acid at position 6 (X.sub.aa6) was
used.
[0113] Finally, the Fmoc group was removed with 20% piperidine in
DMF as described above, and the peptidyl-resins were washed with
DMF (4.times.0.5 mL) and DCM (4.times.0.5 mL). They were then dried
on the reactor block by applying a constant pressure of nitrogen
gas (5 psi) for 10-15 min.
Cleavage/Deprotection
[0114] The desired peptides were cleaved/deprotected from their
respective peptidyl-resins by treatment with a TFA cleavage mixture
as follows. A solution of TFA/water/tri-isopropylsilane (94:3:3)
(1.0 mL) was added to each well in the reactor block, which was
then vortexed for 2 hrs. The TFA solutions from the wells were
collected by positive pressure into pre-tared vials located in a
matching 96-vial block on the bottom of the reactor. The resins in
the wells were rinsed twice with an additional 0.5 mL of TFA
cocktail and the rinses were combined with the solutions in the
vials. These were dried in a SpeedVac.TM. (Savant) to yield the
crude peptides, typically in >100% yields (20-40 mgs). The crude
peptides were either washed with ether or more frequently
re-dissolved directly in 2 mL of DMSO or 50% aqueous acetic acid
for purification by preparative HPLC as follows.
Preparative HPLC Purification of the Crude Peptides
[0115] Preparative HPLC was carried out either on a Waters Model
4000 or a Shimadzu Model LC-8A liquid chromatograph. Each solution
of crude peptide was injected into a YMC S5 ODS (20.times.100 mm)
column and eluted using a linear gradient of MeCN in water, both
buffered with 0.1% TFA. A typical gradient used was from 20% to 70%
0.1% TFA/MeCN in 0.1% TFA/water over 15 min. at a flow rate of 14
mL/min with effluent UV detection at 220 nm. The desired product
eluted well separated from impurities, typically after 10-11 min.,
and was usually collected in a single 10-15 mL fraction on a
fraction collector. The desired peptides were obtained as amorphous
white powders by lyophilization of their HPLC fractions.
HPLC Analysis of the Purified Peptides
[0116] After purification by preparative HPLC as described above,
each peptide was analyzed by analytical RP-HPLC on a Shimadzu
LC-10AD or LC-10AT analytical HPLC system consisting of: a SCL-10A
system controller, a SIL-10A auto-injector, a SPD10AV or SPD-M6A
UV/VIS detector, or a SPD-M10A diode array detector. A YMC ODS S3
(4.6.times.50 mm) column was used and elution was performed using
one of the following gradients: 10-70% B in A over 8 min, 2.5
mL/min. (method A); 5-80% B in A over 8 min, 2.5 mL/min. (method
B); 5-70% B in A over 8 min., 2.5 mL/min. (method C); 25-75% B in A
over 8 min, 2.5 mL/min (method D); 20-75% B in A over 8 min, 2.5
mL/min. (method E); 15-70% B in A over 8 min, 2.5 mL/min. (method
F); 10-90% B in A over 8 min, 2.5 mL/min. (method G); 20-65% B in A
over 8 min, 2.5 mL/min. (method H); 5-90% B in A over 8 min., 2.0
mL/min. (method I); 5-90% B in A over 8 min., 2.5 mL/min. (method
J); 20-80% B in A over 8 min., 2.5 mL/min. (method K); 10-100% B in
A over 8 min., 2.5 mL/min. (method L); 10-75% B in A over 8 min.,
2.5 mL/min. (method M). Mobile phase A: 0.1% TFA/water; mobile
phase B: 0.1% TFA/acetonitrile. The purity was typically
>90%.
Characterization by Mass Spectrometry
[0117] Each peptide was characterized by electrospray mass
spectrometry (ES-MS) either in flow injection or LC/MS mode.
Finnigan SSQ7000 single quadrupole mass spectrometers
(ThermoFinnigan, San Jose, Calif.) were used in all analyses in
positive and negative ion electrospray mode. Full scan data was
acquired over the mass range of 300 to 2200 amu for a scan time of
1.0 second. The quadrupole was operated at unit resolution. For
flow injection analyses, the mass spectrometer was interfaced to a
Waters 616 HPLC pump (Waters Corp., Milford, Mass.) and equipped
with an HTS PAL autosampler (CTC Analytics, Zwingen, Switzerland).
Samples were injected into a mobile phase containing 50:50
water:acetonitrile with 0.1% ammonium hydroxide. The flow rate for
the analyses was 0.42 mL/min. and the injection volume 6 .mu.l. A
ThermoSeparations Constametric 3500 liquid chromatograph
(ThermoSeparation Products, San Jose, Calif.) and HTS PAL
autosampler were used for LC/MS analyses. Chromatographic
separations were achieved employing a Luna C.sub.18, 5 micron
column, 2.times.30 mm (Phenomenex, Torrance, Calif.). The flow rate
for the analyses was 1.0 mL/min and column effluent was split, so
that the flow into the electrospray interface was 400 .mu.l/min. A
linear gradient from 0% to 100% B in A over 4 minutes was run,
where mobile phase A was 98:2 water:acetonitrile with 10 mM
ammonium acetate and mobile phase B was 10:90 water:acetonitrile
with 10 mM ammonium acetate. The UV response was monitored at 220
nm. The samples were dissolved in 200 .mu.l 50:50 H.sub.2O:MeCN
(0.05% TFA). The injection volume was 5 .mu.l.
[0118] In all cases, the experimentally measured molecular weight
was within 0.5 Daltons of the calculated mono-isotopic molecular
weight.
EXAMPLE 2
Synthesis of N-Acylated and N-Alkylated 11-Mer Peptide Analogs
(A) General Procedure for the Synthesis of N-Alkylated 11-Mer
Peptide Analogs by Reductive Alkylation
[0119] The synthesis of N-alkylated 11-mer peptide analogs was
started from the protected intermediate 11-mer peptidyl-resin (1)
(0.025 mmol), which was prepared by the general method described
herein. The Fmoc group was removed using the procedure described in
that method, to yield the protected resin intermediate 2. This was
swollen in DMF, washed 3 times with 1% AcOH/DMF, and then treated
with 2-20 eq. of aldehyde or N-Boc-protected aminoaldehyde (see
synthesis below), dissolved in 1% AcOH/DMF (or CH.sub.2Cl.sub.2) (1
M), and the same excess amount of Na(AcO).sub.3BH as that of the
aldehyde. After overnight reaction, the resin was drained, washed
with DMF and DCM, 3 times each, and dried. The reductively
alkylated peptide (4) was cleaved and deprotected by treatment with
TFA/tri-isopropylsilane/water (90:5:5, v:v:v; 1-2 mL) for 2 hrs.
The resin was filtered off and rinsed with 1 mL of cleavage
solution, which was combined with the filtrate and dried in a
SpeedVac.TM. (Savant) to yield the crude product. This was purified
by preparative HPLC as described in the general peptide synthesis
method outlined herein. The purity and identity of the desired
products were confirmed by analytical HPLC and electrospray MS.
##STR9##
[0120] N-Boc-protected aminoaldehydes were synthesized using
Castro's procedure (Fehrentz, J. A., and Castro, B., Synthesis,
1983, 676-678) as follows. The Boc-protected amino acid (2.0 mmol)
was dissolved in 5 mL DCM. BOP reagent (1.1 eq.) and DIEA (1.15 eq)
were added. After 5 minutes, a solution of
N,O-dimethylhydroxylamine (1.2 eq) and DIEA (1.3 eq) in 5 mL DCM
was added. The reaction mixture was stirred for 2 hrs, diluted with
DCM (30 mL), and washed with 2N HCl (3.times.), sat. NaHCO.sub.3
(3.times.) and brine (1.times.). The organic extracts were dried
over MgSO.sub.4, filtered and evaporated to dryness to yield the
Weinreb amide. This was then dissolved in ether or THF (10
mL/mmol)) and reacted with a 1 M solution of LiAlH.sub.4 in THF (2
mL/mmol of hydroxamate) for 30 minutes. The reaction mixture was
quenched with 5 mL of 0.35 M KHSO.sub.4, and diluted with ether (20
mL). The aqueous phase was separated and extracted with ether
(3.times.20 mL). The combined ether extracts were washed with 2N
HCl (2.times.), sat. NaHCO.sub.3 (2.times.) and brine (1.times.),
dried over MgSO.sub.4, filtered and evaporated to dryness to yield
the Boc-protected aldehyde in 20-30% yield. The aldehyde was
characterized by .sup.1H-NMR and electrospray MS, and was used in
the reductive alkylation step without further purification.
(B) General Procedure for the Synthesis of N-Acylated 11-Mer
Peptide Analogs.
[0121] Similarly, the synthesis of the N-acylated 11-mer peptide
analogs was started from the protected 11-mer peptidyl-resin
intermediate (1) (0.025 mmol), prepared as described herein. The
Fmoc group was removed using the procedure described herein, and
the resulting resin intermediate 2 was coupled with the relevant
Fmoc-protected amino acid or carboxylic acid using the coupling
protocol described in the general method described herein. In cases
where the appropriate anhydride was available, the N-acylation was
performed using 10 eq. of the anhydride in NMP. The resulting
12-mer analogs (3) were cleaved/deprotected and purified by prep.
HPLC by the general method described herein.
(C) General Procedure for the Synthesis of N-Carbamate Derivatives
of 1-Mer Peptide Analogs.
[0122] The synthesis of N-carbamate derivatives of 11-mer peptide
analogs may be started from the protected 1'-mer peptidyl-resin
intermediate (1) (0.025 mmol), prepared as described herein. The
Fmoc group is removed using the procedure described herein, and the
resulting resin intermediate 2 is allowed to react with the
relevant chloroformate in the presence of an appropriate base such
as a tertiary amine, or with a di-carbonate or an activated
carbonate such as p-nitrophenyl or phenyl carbonate. Similarly,
N-carbamate derivatives of 10-mer peptide analogs may be prepared
starting from a protected 10-mer peptidyl-resin intermediate, Fmoc
removal and reaction of the resulting peptidyl-resin intermediate
with the relevant chloroformate, di-carbonate or activated
carbonate.
(D) General Procedure for the Synthesis of N-Urea Derivatives of
11-Mer Peptide Analogs.
[0123] The synthesis of N-urea derivatives of 11-mer peptide
analogs may be started from the protected 1'-mer peptidyl-resin
intermediate (1) (0.025 mmol), prepared as described herein. The
Fmoc group is removed using the procedure described herein, and the
resulting resin intermediate 2 is allowed to react with the
relevant isocyanate prepared, for example, as in K. Burgess et al.,
J. Am. Chem. Soc. 1997, 119, 1556-1564; alternatively, the resin
intermediate 2 may be allowed to react with the relevant carbamyl
chloride. Similarly, N-urea derivatives of 10-mer peptide analogs
may be prepared starting from a protected 10-mer peptidyl-resin
intermediate, Fmoc removal and reaction of the resulting
peptidyl-resin intermediate with the relevant isocyanate or
carbamyl chloride.
(E) General Procedure for the Synthesis of N-Sulfonamides of 11-Mer
Peptide Analogs.
[0124] The synthesis of N-sulfonamides of 11-mer peptide analogs
may be started from the protected 11-mer peptidyl-resin
intermediate (1) (0.025 mmol), prepared as described herein. The
Fmoc group is removed using the procedure described herein, and the
resulting resin intermediate 2 is allowed to react with the
relevant sulfonyl chloride. Similarly, N-sulfonamides of 10-mer
peptide analogs may be prepared starting from a protected 10-mer
peptidyl-resin intermediate, Fmoc removal and reaction of the
resulting peptidyl-resin intermediate with the relevant sulfonyl
chloride.
(F) General Procedure for the Synthesis of N-Sulfonylurea
Derivatives of 11-Mer Peptide Analogs.
[0125] The synthesis of N-sulfonylurea derivatives of 11-mer
peptide analogs may be started from the protected 11-mer
peptidyl-resin intermediate (1) (0.025 mmol), prepared as described
herein. The Fmoc group is removed using the procedure described
herein, and the resulting resin intermediate 2 is allowed to react
with the relevant sulfamoyl chloride R.sub.4R.sub.5N--SO.sub.2--Cl
to yield a sulfonyl urea intermediate (see, for example, P. Davern
et al. J. Chem. Soc., Perkin Trans. 2, 1994 (2), 381-387).
Similarly, N-sulfonyl urea derivatives of 10-mer peptide analogs
may be prepared starting from a protected 10-mer peptidyl-resin
intermediate, Fmoc removal and reaction of the resulting
peptidyl-resin intermediate with the relevant sulfamoyl chloride
R.sub.4R.sub.5N--SO.sub.2--Cl.
EXAMPLE 3
Synthesis of N-Arylalkyl Amides of 10-Mer Peptide Analogs
[0126] The synthesis of N-arylalkyl amides of 10-mer peptide
analogs was started with a reductive alkylation reaction of a
relevant arylalkylamine with an alkoxybenzaldehyde resin as in the
following example. 2-(3,5-Dimethoxy-4-formylphenoxy)ethoxymethyl
polystyrene resin (Novabiochem, 1.12 mmol/gram, 0.025 mmol, 27.3
mg) was washed with 1% Acetic Acid in DCM (5.times.3 mL). A
solution of 2-(2-pentafluorophenyl)ethyl amine (0.125 mmol, 26.4
mg) in DCM (3 mL) was added to the resin. After 5 minutes, solid
NaBH(OAc).sub.3 (0.125 mmol, 26.5 mg,) was added and the reaction
was vortexed for 16 hours. The resin was rinsed with DMF (5.times.3
mL) and DCM (5.times.3 mL).
[0127] A solution of Fmoc-[BIP(2-Et)]-OH (0.05 mmol, 25.3 mg) and
HOAt (0.05 mmol, 6.81 mg) in NMP(0.5 mL) was added to the resin
followed by DIC (0.05 mmol, 7.82 .mu.L). The reaction was vortexed
for 16 hrs. The resin was rinsed with NMP(5.times.3 mL). The
remaining sequence of the desired 10-mer N-arylalkyl amide analog
was then assembled as described in Example 1.
EXAMPLE 4
Solid Phase Synthesis of 11-mer Peptide Analogs Using an Applied
Biosystems Model 433A Peptide Synthesizer
[0128] Following is the general description for the solid phase
synthesis of typical 11-mer peptide analogs, using an upgraded
Applied Biosystems Model 433A peptide synthesizer. The upgraded
hardware and software of the synthesizer enabled conductivity
monitoring of the Fmoc deprotection step with feedback control of
coupling. The protocols allowed a range of synthesis scale from
0.05 to 1.0 mmol.
[0129] The incorporation of the two non-natural C-terminal amino
acid residues was described earlier in connection with simultaneous
synthesis of 11-mer analogs. Such a Fmoc-protected dipeptidyl resin
was used in this ABI synthesis. The Fmoc-protected dipeptidyl-resin
(0.1 mmol) was placed into a vessel of appropriate size on the
instrument, washed 6 times with NMP and deprotected using two
treatments with 22% piperidine/NMP (2 and 8 min. each). One or two
additional monitored deprotection steps were performed until the
conditions of the monitoring option were satisfied (<10%
difference between the last two conductivity-based deprotection
peaks). The total deprotection time was 10-12 min. The deprotected
dipeptidyl-resin was washed 6 times with NMP and then coupled with
the next amino acid. The procedure is illustrated by the example
used in the next step. Thus, Fmoc-Asp(OtBu)-OH was coupled next
using the following method: Fmoc-Asp(OtBu)-OH (1 mmol, 10 eq.) was
dissolved in 2 mL of NMP and activated by subsequent addition of
0.45 M HBTU/HOBt in DMF (2.2 mL) and 2 M DIEA/NMP (1 mL). The
solution of the activated Fmoc-protected amino acid was then
transferred to the reaction vessel and the coupling was allowed to
proceed for 30 to 60 min., depending on the feedback from the
deprotection steps. The resin was then washed 6 times with NMP, and
subjected to 8 additional deprotection/coupling cycles as described
above in order to complete the assembly of the desired sequence.
The Fmoc-amino acids sequentially used were: Fmoc-Ser(tBu)-OH,
Fmoc-Thr(tBu)-OH, Fmoc-Phe-OH, Fmoc-Thr(tBu)-OH, Fmoc-Gly-OH,
Fmoc-Glu(OtBu)-OH, Fmoc-Ala-OH and Fmoc-His(Trt)-OH. Finally, the
Fmoc group was removed with 22% piperidine in NMP as described
above, and the peptidyl-resin was washed 6 times with NMP and DCM,
and dried in vacuo.
[0130] Alternatively, a modified coupling protocol was used in
which the Fmoc-protected amino acid (1 mmol) was activated by
subsequent addition of 0.5 M HOAt in NMP (2 mL) and 1 M DIC/NMP (1
mL), transferred to the reaction vessel and allowed to couple for
1-2 hrs.
Cleavage/Deprotection
[0131] The desired peptide was cleaved/deprotected from its
respective peptidyl-resin (0.141 g) by treatment with a solution of
TFA/water/tri-isopropylsilane (94:3:3) (2.5 mL) for 2 hrs. The
resin was filtered off, rinsed with TFA cleavage solution (0.5 mL),
and the combined TFA filtrates were dried in vacuo. The resulting
solid was triturated and washed with diethyl ether, and finally
dried, to yield 35.6 mg (58%) of crude peptide product as a white
solid. This was purified by preparative HPLC as described herein.
The gradient used was from 20% to 75% 0.1% TFA/MeCN in 0.1%
TFA/water over 15 min. The fraction containing a pure product was
lyophilized, to yield 7.2 mg (20% recovery) of pure product.
EXAMPLE 5
Synthesis of Biphenylalanine Analogs at Position-10 and
Position-11
[0132] For those analogs wherein position-10 and position-11
residues were represented by substituted phenylalanine analogs,
i.e. biphenylalanine analogs (Bip-analogs), their incorporation
into the peptide chain was carried out in one of two
approaches.
Approach A: Solid Phase Suzuki Condensation
[0133] In approach A, solid phase Suzuki condensation was practiced
to prepare the required modified phenylalanine residue in a manner
suitable for carrying out subsequent solid phase peptide synthesis
to obtain the target peptides. When the amino acid at position-11
in the target peptide was represented by a modified phenylalanine
residue, it was prepared as shown in Scheme 3. After removal of the
Boc .alpha.-amine protecting group, chain elongation was continued
using multiple peptide synthesis as described in the previous
section to obtain the desired 11-mer peptides or its derivatives
thereof. When the modified phenylalanine analog was in position-10
of the target peptides, the required amino acid was prepared using
a suitable dipeptide resin as shown in Scheme 4. The resulting
dipeptidyl resin containing the required modified phenylalanine
derivative was then used to carry out the synthesis of the target
11-mer peptide or its derivatives thereof. When both position-10
and position-11 required novel biphenylalanine residues, two
sequential solid phase Suzuki reactions were carried out as shown
in Scheme 5. General Procedure for Preparation of Resin Containing
Biphenylalanine Residue at Position-11 (Suzuki Couplings).
##STR10## Procedure A:
[0134] Polystyrene (1% DVB crosslinked) resins (50 mg, 0.025 mmole)
derivatized with an N.alpha.-Boc-4-iodophenylalanine residue either
attached directly via a Knorr linkage (Boc-amino acid-resin) or via
an amino acid-Knorr linkage (Boc-dipeptide-resin) were weighed into
13.times.100 mm glass culture tubes with screw caps. Aryl-boronic
acids (0.5 mmole) were dissolved in 0.75 ml of 25% by volume
diisopropylethylamine in N-methylpyrrolidinone and added to the
resins followed by 0.05 ml of an N-methylpyrrolidinone solution
containing 1.0 mg of tetrakis(triphenylphospine)palladium(0)
catalyst (ca. 3.5 mole %). The resulting mixtures were blanketed
with a stream of nitrogen and the reaction vessels tightly capped
and maintained at 85-90.degree. C. for 17-20 hours with periodic
shaking. The resins were washed with 5.times.1 ml of
N-methylpyrrolidinone and 5.times.1 ml of dichloromethane prior to
Boc group cleavage (see General Procedure below).
Procedure B:
[0135] The reactions were performed as in General Procedure A
except a different catalyst was employed. The catalyst solution was
prepared by dissolving 9.0 mg of palladium(II) acetate and 56 mg of
2-(dicyclohexylphosphino)biphenyl in 2.0 ml of
N-methylpyrrolidinone. For 0.025 mmole scale reactions, 0.038 ml
(ca. 3 mole %) of catalyst solution was employed.
Procedures for Cleavage of the Boc Group
[0136] Method A: The Boc-protected resins prepared as described in
General Procedures A or B were treated with 0.5 ml of reagent
solution consisting of trimethylsilyl trifluoromethanesulfonate,
2,6-lutidine and dichloromethane (1:1:3 by volume). After 3 such
reagent treatments for 1 hour each with shaking, the resins were
washed with 4.times.1 ml of dichloromethane, 3.times.1 ml of
N,N-dimethylformamide, 3.times.1 ml of 20% MeOH in
N,N-dimethylformamide and 4.times.1 ml dichloromethane prior to
transfer to the automated peptide synthesizer.
[0137] Method B: The Boc-protected resins prepared as described in
General Procedures A or B were treated with 1.0 ml of 1N HCl in
anhydrous 1,4-dioxane for 1 hour at room temperature with shaking.
The resins were washed with 4.times.1 ml of dichloromethane,
3.times.1 ml of 5% diisopropylethylamine in dichloromethane
(vol:vol), 3.times.1 ml of dichloromethane, and 5.times.1 ml of
N-methylpyrrolidinone to provide the free amino-resins ready for
the next acylation (coupling reaction) step.
EXAMPLE 6
General Procedure for Preparation of a Resin Containing a Modified
Biphenylalanine Residue at Position-10
[0138] The general procedures described above (A or B) for Suzuki
coupling were utilized to obtain the required dipeptidyl resin
containing modified Phe at position-10 starting with the amino acid
(at position-11) bound resin as shown in Scheme 4. ##STR11##
EXAMPLE 7
General Procedure for Preparation of Resin Containing
Biphenylalanine Residues at Both Positions 10 and 11
[0139] Utilizing the procedures described for position 11 modified
analogs (Scheme 1) and carrying out the Suzuki coupling procedure
two successive times produced dipeptidyl resins containing modified
phenylalanine residues at both positions-10 and -11 as illustrated
in Scheme 5. ##STR12## Approach B: Synthesis of
Fmoc-Biphenylalanine Derivatives Using Suzuki Condensation in
Solution.
[0140] Using this method, exemplified by the synthesis of
Fmoc-2-methyl-biphenylalanine, several N-.alpha.-Fmoc protected
biphenylalanine derivatives were prepared. They were utilized for
the solid phase synthesis of 11-mers and other peptide analogs as
described herein.
EXAMPLE 8
Synthesis of Fmoc-2-methyl-biphenylalanine
[0141] The following scheme 6 describes the synthesis of
Fmoc-2-methyl-biphenylalanine. ##STR13##
[0142] Boc-L-Tyrosine-O-triflate: To a solution of 37 g (126 mmol
of Boc-tyrosine methyl ester, and 25.4 mL (314 mmol, 2.5 eq.) of
pyridine in 114 mL of dry dichloromethane, kept at -15.degree. C.
under N.sub.2, was added slowly 25.4 mL (151 mmol, 1.2 eq.) of
triflic anhydride. The solution was stirred at -15.degree. C. for
15 min. HPLC analysis indicated that the reaction was complete. The
reaction was quenched by addition of 150 mL of water. The layers
were separated, and the organic layer washed with 2.times.150 mL of
0.5M NaOH, and 2.times.150 mL of 15% citric acid solution. The
organic layer was dried over magnesium sulfate, filtered
concentrated and dried in vacuo to give the crude product as a red
oil. (Crude yield varied between 90% to quantitative).
[0143] Boc-(2-Me) biphenylalanine methyl ester: The above red oil
was dissolved in 70 mL of toluene, and added to a degassed
suspension containing 19.0 g (140 mmol, 1.2 eq.) of o-tolyllboronic
acid, 24.1 g (175 mmol, 1.5 eq.) of potassium carbonate, and 4.6 g
(4.0 mol, 0.034 eq.) of tetrakis(triphenylphosphine) palladium (0)
in 580 mL of toluene preheated at 80.degree. C. The mixture was
heated at 80.degree. C. under N.sub.2 for 3 h, cooled to room
temperature, and then filtered through celite. The reaction mixture
was washed with 2.times.150 mL of 0.5% of NaOH, and 2.times.150 mL
of 15% citric acid solution, dried over magnesium sulfate and
concentrated. The crude mixture thus obtained was purified by
silica gel chromatography using ethyl acetate/heptane (1:9) as
eluant, [crude mixture was preabsorbed on silica gel (2 g silica
gel/g crude mixture), 1:35:: mixture:silica gel used for the
column], yield varied from 50 to 80%.
[0144] Boc-(2-Me) biphenylalanine: To a solution of 44.5 g (120
mmol) of Boc-(2-Me) biphenylalanine methyl ester in 147 mL of
methanol and 442 mL of tetrahydrofuran, kept at room temperature,
was added 147.4 mL of 1N NaOH (147 mmol, 1.2 eq.). HPLC analysis
indicated that the reaction was complete after 1 h. The reaction
mixture was concentrated and partitioned between 500 mL of water
and 300 mL of ether. The ethereal solution was discarded. Aqueous
layer was acidified with 160 mL of 1 N HCl solution, and then
extracted with 2.times.250 mL of ethyl ether. The ethereal
solutions were combined, and dried over magnesium sulfate. After
filtration, concentration and drying 41.5 g of product was
obtained.
[0145] Fmoc-(2-Me) biphenylalanine: To a solution of 41.5 g (117
mmol) of Boc-(2-Me) biphenylalanine in 1 L of dichloromethane, kept
at room temperature, was bubbled in gaseous HCl. A white solid
started to precipitate in approximately 5 min. HPLC taken after 2
hours showed that the reaction was complete. The mixture was
concentrated. The residue was redissolved in 600 mL of
tetrahydrofuran and 150 mL of water, and solid NaHCO.sub.3 was
added slowly until the pH of the mixture was basic (a white solid
precipitated out), followed by addition of 38.9 g (115 mmol, 1 eq.)
of Fmoc-Osu. The mixture was then stirred at room temperature. A
homogeneous biphasic solution was obtained within 1 h. The stirring
was continued at room temperature under N.sub.2 overnight. The
layers were separated. The tetrahydrofuran layer was acidified with
58 mL 2N HCl, and then diluted with 400 mL of ethyl acetate. The
layers were separated, and the organic layer washed with
2.times.100 mL of water, dried over magnesium sulfate, and
concentrated. The crude product was purified using silica gel
column chromatography using dichloromethane as eluant until most of
the impurities had been removed. The solvent was then changed to
25% ethyl acetate in heptane containing 1% acetic acid,
[approximately 23 g silica gel/g crude mixture used for the
column]. The yield was >90% for the three steps.
EXAMPLE 9
General Synthesis of Various Fmoc-biphenylalanine Derivatives
[0146] Synthesis of various biphenyl alanine derivatives were
carried out using the above described procedure, starting with the
commercially available phenol derivative (e.g. Boc-Tyrosine methyl
ester) to prepare the triflate and using the appropriate boronic
acid to prepare the biphenylalanine analogs. When a required
boronic acid was not available from commercial sources the
synthesis of this intermediate was carried out as exemplified in
the following example.
[0147] 2-Ethylphenyl boronic acid: To a solution of 25 g (135 mmol)
of 1-bromo-2-ethylbenzene in 280 mL of dry tetrahydrofuran, kept at
-78.degree. C. in an oven-dried 3 neck flask, was added slowly
(keeping the temperature below -68.degree. C.) 67.5 mL of 2.5N
n-Butyl lithium in hexanes solution (169 mmol, 1.25 eq.). The
reaction was stirred for an additional 1 h, and then 69 mL (405
mmol, 3 eq.) of triethylborate was added slowly, keeping the
temperature below -68.degree. C. The reaction was stirred for an
additional 40 minutes and then the dry ice bath was removed, the
reaction was allowed to warm up to room temperature, and then was
poured into 300 mL of ice cold saturated ammonium chloride
solution. 200 mL of ice cold ethyl acetate was added, and the
mixture stirred for another 30 min. The layers were separated. The
organic layer was washed with water, and brine. It was then dried
over magnesium sulfate, and concentrated to give 19 g (92% yield)
of product. The boronic acid was used without purification in the
next step.
EXAMPLE 10
Synthesis of Fmoc-Protected Biphenylalanine Analogs with
Substitution in the Internal Phenyl Ring
[0148] Synthesis of the Fmoc-protected biphenylalanine analogs with
substitution in the phenyl ring directly attached to the
.beta.-carbon (internal ring) of the amino acid moiety was carried
as depicted in the following scheme 7. ##STR14## ##STR15##
[0149] As a general method, initially a suitably protected tyrosine
derivative was prepared by reaction of Boc-.quadrature.-iodo
alanine with the required 4-iodophenol derivative using a zinc
mediated condensation. The product from this reaction was subjected
to Suzuki condensation reaction as described herein, to afford the
required Fmoc-protected biphenylalanine analogs with substitution
in the phenyl ring directly attached to the .beta.-carbon (internal
ring) of the amino acid moiety. Synthesis of a specific example,
Fmoc-2'-methyl-2-methyl-biphenylalnine is given below.
[0150] Boc-2'-Methyl-Tyrosine benzyl ether methyl ester: 2.2 g (33
mmol) of oven-dried zinc dust was placed in an oven dried flask
under nitrogen. 5.2 mL of dry tetrahydrofuran, and 140 .mu.L (1.6
mmol) of 1,2-dibromoethane were added, and the mixture warmed
briefly with a heat gun until the solvent began to boil, and then
stirred vigorously for a few minutes. This procedure was repeated
five times, and then the reaction mixture was cooled to 35.degree.
C. 40 .mu.L (0.32 mmol) of chlorotrimethylsilane was added, and the
mixture stirred vigorously at 35.degree. C. for 30 min. A solution
of 3 mL of 1.04 g (3.17 mmol) of Boc-iodoalanine methyl ester in
1:1 tetrahydrofuran:dimethylacetamide was added slowly, and the
reaction mixture stirred at 35.degree. C. for 30 min. A solution of
3 mL of 1:1 tetrahydrofuran:dimethylacetamide containing 819 mg
(2.5 mmol) of 4-iodo-2-methyl-1-benzyloxybenzene was added slowly,
followed by 338 mg (1.11 mmol) of tri-o-tolylphosphine, and 288 mg
(0.31 mmol) of Pd.sub.2(dba).sub.3. The reaction mixture was
degassed, and then stirred at 60.degree. C. for 4 h. The reaction
mixture was cooled to room temperature, diluted with ethyl acetate,
and filtered through celite. The filtrate was washed with
2.times.25 mL of 1N HCl, dried over magnesium sulfate, filtered and
concentrated. The product was purified by silica gel chromatography
(72% yield).
[0151] Boc-2'-Methyl-Tyrosine methyl ester: A suspension of 7.5 g
(18.7 mmol) of the above compound (Boc-2'-methyl-tyrosine benzyl
ether methyl ester) in 30 mL of tetrahydrofuran, and 2.25 g 10%
Degussa type 10% palladium on carbon was stirred under hydrogen
atmosphere at room temperature and atmospheric pressure for 2 days.
The reaction mixture was then filtered through celite, and
concentrated. The product was purified by silica gel chromatography
(74% yield).
[0152] Fmoc-2'-methyl-2-methyl-biphenyl alanine: This compound was
prepared using the Suzuki Condensation procedure described herein,
using Boc-2'-Methyl-Tyrosine methyl ester as the starting material.
The product obtained in the above Suzuki condensation reaction,
after removal of the Boc-group and reprotection with Fmoc-group
using conditions described herein afforded the desired product.

EXAMPLE 12
[0158] Synthesis and testing of a peptide corresponding to the
"message" sequence of GLP-1 and of the same peptide to which an
"address" biphenylalanine dipeptide unit is attached at the
C-terminus
[0159] The peptide corresponding to the N-terminal 1-9 sequence of
GLP-1, His-Ala-Glu-Gly-Thr-Phe-Thr-Ser-Asp-NH2, which in this
invention is referred to as the "message" sequence of GLP-1, and
the GLP-1 11-mer peptide analog
His-Ala-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Bip-Bip-NH2, which is comprised
of the message sequence of GLP-1 and of a C-terminal
biphenylalanine dipeptide unit, were prepared using the methods
described herein and tested in the cAMP cell-based assay describe
in Example 13. The GLP-1 11-mer peptide analog stimulated cAMP
production in a dose-response manner corresponding to an EC.sub.50
value of 1.1 micromolar, determined as in Example 13. In the same
assay, the EC.sub.50 value determined for the peptide corresponding
to the "message" sequence of GLP-1 was greater than 1 millimolar.
The EC.sub.50 value for GLP-1, used in the assay as a positive
control, was less than 0.100 nanomolar.
EXAMPLE 13
Cyclic AMP Determination
[0160] The GLP-1 receptor is a G-protein coupled receptor. GLP-1
(7-36)-amide, the biologically active form, binds to the GLP-1
receptor and through signal transduction causes activation of
adenylate cyclase and raises intracellular cAMP levels. To monitor
agonism of peptide compounds in stimulating the GLP-1 receptor,
adenyl cyclase activity was monitored by assaying for cellular cAMP
levels. Full-length human glucagon-like peptide 1 receptor was
stably expressed in CHO-K1 cells. The clones were screened for best
expression of GLP-1R and CHO-GLP-1R-19 was selected. Cells were
cultured in Ham's F12 nutritional media (Gibco #11765-054), 10%
FBS, 1.times. L-Glutamine, 1.times. Pen/Strep, and 0.4 mg/ml G418.
CHO-GLP-1R-19 cells (2,500 in 100 .mu.l of media) were plated into
each well of a 96-well tissue culture microtiter plate and
incubated in 5% CO.sub.2 atmosphere at 37.degree. C., for 72 h. On
the day of the assay, cells were washed once with 100 .mu.l of PBS.
To cells in each well, 10 .mu.l of compound and 90 .mu.l of
reaction media (Phenol red free DMEM media with low glucose
(Gibco#11054-020), 0.1% BSA (Sigma #A7284), 0.3 mM IBMX
(3-isobutyl-1 methylxanthine, Sigma #15879) were added and
incubated at 37.degree. C. for 1 h. The compounds were initially
screened at 1 .mu.M and 10 .mu.M for stimulation of cAMP. Dose
dependence for compounds showing 50% of maximal GLP-1 (at 100 nM)
activity was determined at half-log concentrations in duplicate.
After incubation, medium was removed and cells were washed once
with 100 .mu.l of PBS. Fifty .mu.l of lysis reagent-1 from the
cyclic AMP SPA kit (Amersham Pharmacia Biotech, RPA 559; reagents
were reconstituted according to the kit instructions) was added
into each well. The plate was shaken at room temperature for 15
min. Twenty .mu.l of lysate was transferred into each well of a
96-well OptiPlate (Packard # 6005190) and 60 .mu.l of SPA
immunoreagent from the kit was added. After incubation at room
temperature for 15-18 h, plates were counted 2 min each/well in a
TopCount NXT(Packard).
[0161] In each 96-well plate, GLP-1 (control), and five compounds
(in duplicate) were run at seven half-log doses. Ten nM GLP-1 was
plated into ten additional wells to serve as a reference standard
for determination of maximal activity. The data obtained was
processed in Excel-fit database. From a cyclic AMP standard curve,
the amounts of released cAMP were determined and the % maximal
activity was calculated and plotted against log compound
concentration. The data was analyzed by nonlinear regression curve
fit (sigmoidal dose) to determine the EC.sub.50 of the
compounds.
EXAMPLE 14
In-Vivo Studies
[0162] The in-vivo glucose lowering properties for four
representative 11-mer peptides, compound A, compound B, compound C
and compound D in a rat model is described below. Continuous
intravenous infusion of compound A and compound B significantly
attenuated the postprandial glucose excursion curve in subcutaneous
glucose tolerance test (scGTT) (see FIG. 1 and FIG. 2). In
addition, these two 1'-mer peptides administered by subcutaneous
injection also produced a significant glucose lowering effect in
this model (see FIG. 3 and FIG. 4). A clear dose-response
relationship was observed following both continuous intravenous
infusion and subcutaneous bolus injection of the analogs for their
glucose lowering effects. The significant glucose lowering effect
for compound A and compound B was observed at 12 and 120
.mu.mol/kg/min, respectively, when the compound was administered by
continuous infusion. For the subcutaneous administration, the
maximum effective doses for Compound A and Compound B were about 2
and 20 nmol/kg, respectively.
[0163] For compounds C and D, studies using subcutaneous injection
in a rat intraperitoneal glucose tolerance test (ipGTT) model
showed that significant glucose excursion attenuation could be
achieved for both compounds in a dose-related fashion(see FIG. 5
and FIG. 6). FIG. 7 shows the effects of native GLP-1 in this
model.

Dosage and Formulation
[0199] A suitable GLP-1 peptide mimic can be administered to
patients to treat diabetes and other related diseases as the
compound alone and or mixed with an acceptable carrier in the form
of pharmaceutical formulations. Those skilled in the art of
treating diabetes can easily determine the dosage and route of
administration of the compound to mammals, including humans, in
need of such treatment. The route of administration may include but
is not limited to oral, intraoral, rectal, transdermal, buccal,
intranasal, pulmonary, subcutaneous, intramuscular, intradermal,
sublingual, intracolonic, intraoccular, intravenous, or intestinal
administration. The compound is formulated according to the route
of administration based on acceptable pharmacy practice (Fingl et
al., in The Pharmacological Basis of Therapeutics, Ch. 1, p. 1,
1975; Remington's Pharmaceutical Sciences, 18.sup.th ed., Mack
Publishing Co, Easton, Pa., 1990).
[0200] The pharmaceutically acceptable GLP-1 peptide mimic
composition of the present invention can be administered in
multiple dosage forms such as tablets, capsules (each of which
includes sustained release or timed release formulations), pills,
powders, granules, elixirs, in situ gels, microspheres, crystalline
compleses, liposomes, micro-emulsions, tinctures, suspensions,
syrups, aerosol sprays and emulsions. The composition of the
present invention can also be administered in oral, intravenous
(bolus or infusion), intraperitoneal, subcutaneous, transdermally
or intramuscular form, all using dosage forms well known to those
of ordinary skill in the pharmaceutical arts. The composition may
be administered alone, but generally will be administered with a
pharmaceutical carrier selected on the basis of the chosen route of
administration and standard pharmaceutical practice.
[0201] The dosage regimen for the composition of the present
invention will, of course, vary depending upon known factors, such
as the pharmacodynamic characteristics of the particular agent and
its mode and route of administration; the species, age, sex,
health, medical condition, and weight of the recipient; the nature
and extent of the symptoms; the kind of concurrent treatment; the
frequency of treatment; the route of administration, the renal and
hepatic function of the patient, and the effect desired. A
physician or veterinarian can determine and prescribe the effective
amount of the drug required to prevent, counter, or arrest the
progress of the disease state.
[0202] By way of general guidance, the daily oral dosage of the
active ingredient, when used for the indicated effects, will range
between about 0.001 to 1000 mg/kg of body weight, preferably
between about 0.01 to 100 mg/kg of body weight per day, and most
preferably between about 0.6 to 20 mg/kg/day. Intravenously, the
daily dosage of the active ingredient when used for the indicated
effects will range between 0.001 ng to 100.0 ng per min/per Kg of
body weight during a constant rate infusion. Such constant
intravenous infusion can be preferably administered at a rate of
0.01 ng to 50 ng per min per Kg body weight and most preferably at
0.1 ng to 10.0 mg per min per Kg body weight. The composition of
this invention may be administered in a single daily dose, or the
total daily dosage may be administered in divided doses of two,
three, or four times daily. The composition of this invention may
also be administered by a depot formulation that will allow
sustained release of the drug over a period of days/weeks/months as
desired.
[0203] The composition of this invention can be administered in
intranasal form via topical use of suitable intranasal vehicles, or
via transdermal routes, using transdermal skin patches. When
administered in the form of a transdermal delivery system, the
dosage administration will, of course, be continuous rather than
intermittent throughout the dosage regimen.
[0204] The composition is typically administered in a mixture with
suitable pharmaceutical diluents, excipients, or carriers
(collectively referred to herein as pharmaceutical carriers)
suitably selected with respect to the intended form of
administration, that is, oral tablets, capsules, elixirs, aerosol
sprays generated with or without propallant and syrups, and
consistent with conventional pharmaceutical practices.
[0205] For instance, for oral administration in the form of a
tablet or capsule, the active drug component can be combined with
an oral, non-toxic, pharmaceutically acceptable, inert carrier such
as but not limited to, lactose, starch, sucrose, glucose, methyl
cellulose, magnesium stearate, dicalcium phosphate, calcium
sulfate, mannitol, and sorbitol; for oral administration in liquid
form, the oral drug components can be combined with any oral,
non-toxic, pharmaceutically acceptable inert carrier such as, but
not limited to, ethanol, glycerol, and water. Moreover, when
desired or necessary, suitable binders, lubricants, disintegrating
agents, and coloring agents can also be incorporated into the
mixture. Suitable binders include, but not limited to, starch,
gelatin, natural sugars such as, but not limited to, glucose or
beta-lactose, corn sweeteners, natural and synthetic gums such as
acacia, tragacanth, or sodium alginate, carboxymethylcellulose,
polyethylene glycol, and waxes. Lubricants used in these dosage
forms include sodium oleate, sodium stearate, magnesium stearate,
sodium benzoate, sodium acetate, and sodium chloride. Disintegrants
include, but are not limited to, starch, methyl cellulose, agar,
bentonite, and xanthan gum.
[0206] The composition of the present invention may also be
administered in the form of mixed micellar or liposome delivery
systems, such as small unilamellar vesicles, large unilamellar
vesicles, and multilamellar vesicles. Liposomes can be formed from
a variety of phospholipids, such as cholesterol, stearylamine, or
phosphatidylcholines. Permeation enhancers may be added to enhance
drug absorption.
[0207] Since prodrugs are known to enhance numerous desirable
qualities of pharmaceuticals (i.e., solubility, bioavailability,
manufacturing, etc.) the compounds of the present invention may be
delivered in prodrug form. Thus, the present invention is intended
to cover prodrugs of the presently claimed compounds, methods of
delivering the same and compositions containing the same.
[0208] The compositions of the present invention may also be
coupled with soluble polymers as targetable drug carriers. Such
polymers can include polyvinyl-pyrrolidone, pyran copolymer,
polyhydroxypropyl-methacrylamide-phenol,
polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine
substituted with palmitoyl residues. Furthermore, the composition
of the present invention may be combined with a class of
biodegradable polymers useful in achieving controlled release of a
drug, for example, polylactic acid, polyglycolic acid, copolymers
of polylactic and polyglycolic acid, polyepsilon caprolactone,
polyhydroxy butyric acid, polyorthoesters, polyacetals,
polydihydropyrans, polycyanoacylates, and crosslinked or
amphipathic block copolymers of hydrogels.
[0209] Dosage forms (pharmaceutical compositions) suitable for
administration may contain from about 0.1 milligram to about 500
milligrams of active ingredient per dosage unit. In these
pharmaceutical compositions the active ingredient will ordinarily
be present in an amount of about 0.5-95% by weight based on the
total weight of the composition.
[0210] Gelatin capsules may contain the active ingredient and
powdered carriers, such as lactose, starch, cellulose derivative,
magnesium stearate, and stearic acid. Similar diluents can be used
to make compressed tablets. Both tablets and capsules can be
manufactured as sustained release products to provide for
continuous release of medication over a period of hours. Compressed
tablets can be sugar coated or film coated to mask any unpleasant
taste and protect the tablet from the atmosphere, or enteric coated
for selective disintegration in the gastrointestinal tract.
[0211] Liquid dosage forms for oral administration can contain
coloring and flavoring to increase patient acceptance.
[0212] In general, water, a suitable oil, saline, aqueous dextrose
(glucose), and related sugar solutions and glycols such as
propylene glycol or polyethylene glycols are suitable carriers for
parenteral solutions. Solution for parenteral administration
preferably contains a water-soluble salt of the active ingredient,
suitable stabilizing agents, and if necessary, buffer substances.
Antioxidizing agents such as sodium bisulfite, sodium sulfite, or
ascorbic acid, either alone or combined, are suitable stabilizing
agents. Also used are citric acid and its salts and sodium EDTA. In
addition, parenteral solutions can contain preservatives, such as
benzalkonium chloride, methyl- or propyl-paraben, and
chlorobutanol.
[0213] Suitable pharmaceutical carriers are described in Remington:
The Science and Practice of Pharmacy, Nineteenth Edition, Mack
Publishing Company, 1995, a standard reference text in this
field
[0214] Representative useful pharmaceutical dosage forms for
administration of the compound of this invention can be illustrated
as follows:
Capsules
[0215] A large number of unit capsules can be prepared by filling
standard two-piece hard gelatin capsules with 100 milligrams of
powdered active ingredient, 150 milligrams of lactose, 50
milligrams of cellulose, and 6 milligrams magnesium stearate.
Soft Gelatin Capsules
[0216] A mixture of active ingredient in a digestable oil such as
soybean oil, cottonseed oil or olive oil may be prepared and
injected by means of a positive displacement pump into gelatin to
form soft gelatin capsules containing 100 milligrams of the active
ingredient. The capsules should be washed and dried.
Tablets
[0217] Tablets may be prepared by conventional procedures so that
the dosage unit, for example is 100 milligrams of active
ingredient, 0.2 milligrams of colloidal silicon dioxide, 5
milligrams of magnesium stearate, 275 milligrams of
microcrystalline cellulose, 11 milligrams of starch and 98.8
milligrams of lactose. Appropriate coatings may be applied to
increase palatability or delay absorption.
Injectable
[0218] A parenteral composition suitable for administration by
injection may be prepared by stirring for example, 1.5% by weight
of active ingredient in 10% by volume propylene glycol and water.
The solution should be made isotonic with sodium chloride and
sterilized.
Suspension
[0219] An aqueous suspension can be prepared for oral and/or
parenteral administration so that, for example, each 5 mL contains
100 mg of finely divided active ingredient, 20 mg of sodium
carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol
solution, U.S.P., and 0.025 mL of vanillin or other palatable
flavoring.
Biodegradable Microparticles
[0220] A sustained-release parenteral composition suitable for
administration by injection may be prepared, for example, by
dissolving a suitable biodegradable polymer in a solvent, adding to
the polymer solution the active agent to be incorporated, and
removing the solvent from the matrix thereby forming the matrix of
the polymer with the active agent distributed throughout the
matrix.
[0221] Obviously, numerous modifications and variations of the
present invention are possible in light of the above teachings. It
is therefore understood that within the scope of the appended
claims, the invention may be practiced otherwise than as
specifically described herein.
[0222] The present invention is not to be limited in scope by the
specific embodiments described that are intended as single
illustrations of individual aspects of the invention. Functionally
equivalent methods and components in addition to those shown and
described herein will become apparent to those skilled in the art
from the foregoing description and accompanying drawings. Such
modifications are intended to fall within the scope of the appended
claims.
