[0002] This application claims the benefit under 35 U.S.C. 119(e)

2005 which is incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The invention relates to bridged N-cyclic sulfonamido
compounds fused with a heteroaryl or heterocycloalkyl ring, which
inhibit gamma secretase and .beta.-amyloid peptide release and/or
its synthesis. Therefore, the N-cyclic sulfonamido compounds of the
present invention are useful in the prevention of cognitive
disorders in patients susceptible to cognitive disorders and/or in
the treatment of patients with cognitive disorders in order to
inhibit further deterioration in their condition.
[0005] 2. State of the Art
[0006] Alzheimer's Disease (AD) is a degenerative brain disorder
characterized clinically by progressive loss of memory, cognition,
reasoning, judgment and emotional stability that gradually leads to
profound mental deterioration and ultimately death. AD is a very
common cause of progressive mental failure (dementia) in aged
humans and is believed to represent the fourth most common medical
cause of death in the United States. AD has been observed in races
and ethnic groups worldwide and presents a major present and future
public health problem. The disease is currently estimated to affect
about two to three million individuals in the United States alone.
AD is at present incurable. No treatment that effectively prevents
AD or reverses its symptoms and course is currently known.
[0007] The brains of individuals with AD exhibit characteristic
lesions termed senile (or amyloid) plaques, amyloid angiopathy
(amyloid deposits in blood vessels) and neurofibrillary tangles.
Large numbers of these lesions, particularly amyloid plaques and
neurofibrillary tangles, are generally found in several areas of
the human brain important for memory and cognitive function in
patients with AD. Smaller numbers of these lesions in a more
restrictive anatomical distribution are also found in the brains of
most aged humans who do not have clinical AD. Amyloid plaques and
amyloid angiopathy also characterize the brains of individuals with
Trisomy 21 (Down's Syndrome) and Hereditary Cerebral Hemorrhage
with Amyloidosis of the Dutch Type (HCHWA-D). At present, a
definitive diagnosis of AD usually requires observing the
aforementioned lesions in the brain tissue of patients who have
died with the disease or, rarely, in small biopsied samples of
brain tissue taken during an invasive neurosurgical procedure.
[0008] The principal chemical constituent of the amyloid plaques
and vascular amyloid deposits (amyloid angiopathy) characteristic
of AD and the other disorders mentioned above is an approximately
4.2 kilodalton (kD) protein of about 39-43 amino acids designated
the .beta.amyloid peptide (.beta.AP) or sometimes A.beta., A.beta.P
or .beta./A4. .beta.-Amyloid peptide was first purified and a
partial amino acid sequence was provided by Glenner et al.,
Biochem. Biophys. Res. Commun., 120:885-890 (1984) The isolation
procedure and the sequence data for the first 28 amino acids are
described in U.S. Pat. No. 4,666,829.
[0009] Molecular biological and protein chemical analyses have
shown that .beta.-amyloid peptide is a small fragment of a much
larger precursor protein termed the amyloid precursor protein
(APP), that is normally produced by cells in many tissues of
various animals, including humans. Knowledge of the structure of
the gene encoding APP has demonstrated that 11-amyloid peptide
arises as a peptide fragment that is cleaved from APP by protease
enzyme(s). Sequential processing of the precursor protein by the
enzymes referred to generically as beta- and gamma-secretases,
gives rise to the .beta.-amyloid peptide fragment. Both enzymes
have now been molecularly cloned, and characterized to differing
levels.
[0010] Several lines of evidence indicate that progressive cerebral
deposition of .beta.-amyloid peptide plays a seminal role in the
pathogenesis of AD and can precede cognitive symptoms by years or
decades. See, for example, Selkoe, Neuron, 6:487-498 (1991). The
most important line of evidence is the discovery that missense DNA
mutations at amino acid 717 of the 770-amino acid isoform of APP
can be found in affected members but not unaffected members of
several families with a genetically determined (familial) form of
AD (Goate et al., Nature, 349:704-706 (1990); Chartier Harlan et
al., Nature, 353:844-846 (1989); and Murrell et al., Science,
254:97-99 (1991.) Another such mutation, known as the Swedish
variant, is comprised of a double mutation changing
lysine.sup.595-methionine.sup.596 to
asparagine.sup.595-leucine.sup.596 (with reference to the 695
isoform was found in a Swedish family) was reported in 1992 (Mullan
et al., Nature Genet., 1:345-347 (1992). Genetic linkage analyses
have demonstrated that these mutations, as well as certain other
mutations in the APP gene, are the specific molecular cause of AD
in the affected members of such families. In addition, a mutation
at amino acid 693 of the 770-amino acid isoform of APP has been
identified as the cause of the .beta.-amyloid peptide deposition
disease, HCHWA-D, and a change from alanine to glycine at amino
acid 692 appears to cause a phenotype that resembles AD is some
patients but HCHWA-D in others. The discovery of these and other
mutations in APP in genetically based cases of AD prove that
alteration of APP metabolism, and subsequent deposition of its
.beta.-amyloid peptide fragment, can cause AD.
[0011] Despite the progress which has been made in understanding
the underlying mechanisms of AD and other .beta.-amyloid peptide
related diseases, there remains a need to develop methods and
compositions for treatment of the disease(s). Ideally, the
treatment methods would advantageously be based on drugs, which are
capable of inhibiting .beta.-amyloid peptide release and/or its
synthesis in vivo.
[0012] One approach toward inhibiting amyloid peptide synthesis in
vivo is by inhibiting gamma secretase, the enzyme responsible for
the carboxy-terminal cleavage resulting in production of
.beta.-amyloid peptide fragments of 40 or 42 residues in length.
The immediate substrates for gamma secretase are .beta.-cleaved, as
well as .alpha.-cleaved carboxy-terminal fragments (CTF) of APP.
The gamma-secretase cleavage site on .beta.- and .alpha.-CTF
fragments occurs in the predicted transmembrane domain of APP.
Inhibitors of gamma-secretase have been demonstrated to effect
amyloid pathology in transgenic mouse models (Dovey, H. F., V.
John, J. P. Anderson, L. Z. Chen, P. de Saint Andrieu, L. Y. Fang,
S. B. Freedman, B. Folmer, E. Goldbach, E. J. Holsztynska et al.
(2001). "Functional gamma-secretase inhibitors reduce beta-amyloid
peptide levels in brain." J Neurochem 76(1): 173-81.)
[0013] Gamma secretase is recognized to be a multi-subunit complex
comprised of the presenilins (PS1 or PS2), Nicastrin, Aph-1, and
Pen 2 (De Strooper, B. (2003). "Aph-1, Pen-2, and Nicastrin with
Presenilin generate an active gamma-Secretase complex." Neuron
38(1): 9-12; Edbauer, D., E. Winkler, J. T. Regula, B. Pesold, H.
Steiner and C. Haass (2003). "Reconstitution of gamma-secretase
activity." Nat Cell Biol 5(5): 486-8; Kimberly, W. T., M. J.
LaVoie, B. L. Ostaszewski, W. Ye, M. S. Wolfe and D. J. Selkoe
(2003). "Gamma-secretase is a membrane protein complex comprised of
presenilin, nicastrin, Aph-1, and Pen-2." Proc Natl Acad Sci USA
100(11): 6382-7). Much evidence indicates that PS comprises the
catalytic moiety of the complex, while the other identified
subunits are necessary for proper maturation and sub-cellular
localization of the active enzyme complex (reviewed in De Strooper,
B. (2003). "Aph-1, Pen-2, and Nicastrin with Presenilin generate an
active gamma-Secretase complex." Neuron 38(1): 9-12.) Consistent
with this hypothesis: PS knock-out mice exhibit significant
reductions in 8-amyloid production (De Strooper, B., P. Saftig, K.
Craessaerts, H. Vanderstichele, G. Guhde, W. Annaert, K. Von Figura
and F. Van Leuven (1998). "Deficiency of presenilin-1 inhibits the
normal cleavage of amyloid precursor protein." Nature 391(6665):
387-90; Haass, C. and D. J. Selkoe (1998). "Alzheimer's disease. A
technical KO of amyloid-beta peptide." Nature 391(6665): 339-40;

B. De Strooper (2000). "Total inactivation of gamma-secretase
activity in presenilin-deficient embryonic stem cells." Nat Cell
Biol 2(7): 461-2); Point mutations of putative active site
aspartate residues in PS trans-membrane domains inhibit
.beta.-amyloid production in cells in a dominant negative fashion
(Wolfe, M. S., W. Xia, B. L. Ostaszewski, T. S. Diehl, W. T.
Kimberly and D. J. Selkoe (1999). "Two transmembrane aspartates in
presenilin-1 required for presenilin endoproteolysis and
gamma-secretase activity." Nature 398(6727): 513-7; Kimberly, W.
T., W. Xia, T. Rahmati, M. S. Wolfe and D. J. Selkoe (2000). "The
transmembrane aspartates in presenilin 1 and 2 are obligatory for
gamma-secretase activity and amyloid beta-protein generation." J
Biol Chem 275(5): 3173-8); active site directed substrate-based
transition state isosteres designed to inhibit gamma secretase
directly conjugate to PS (Esler, W. P., W. T. Kimberly, B. L.
Ostaszewski, T. S. Diehl, C. L. Moore, J. Y. Tsai, T. Rahmati, W.
Xia, D. J. Selkoe and M. S. Wolfe (2000). "Transition-state
analogue inhibitors of gamma-secretase bind directly to
presenilin-1." Nat Cell Biol 2(7): 428-34; Li, Y. M., M. Xu, M. T.

Lellis, A. Nadin, J. G. Neduvelil et al. (2000). "Photoactivated
gamma-secretase inhibitors directed to the active site covalently
label presenilin 1." Nature 405(6787): 689-94); finally, allosteric
gamma secretase inhibitors have likewise been demonstrated to bind
directly to PS (Seiffert, D., J. D. Bradley, C. M. Rominger, D. H.
Rominger, F. Yang, J. E. Meredith, Jr., Q. Wang, A. H. Roach, L. A.
Thompson, S. M. Spitz et al. (2000). "Presenilin-1 and -2 are
molecular targets for gamma-secretase inhibitors." J Bid Chem
275(44): 34086-91.)
[0014] Current evidence indicates that in addition to APP
processing leading to .beta.-amyloid synthesis, gamma-secretase
also mediates the intra-membrane cleavage of other type I
transmembrane proteins (reviewed in Fortini, M. E. (2002).
"Gamma-secretase-mediated proteolysis in cell-surface-receptor
signaling." Nat Rev Mol Cell Blot 3(9): 673-84, see also Struhl, G.
and A. Adachi (2000). "Requirements for presenilin-dependent
cleavage of notch and other transmembrane proteins." Mol Cell 6(3):
625-36.) Noteworthy among the known substrates of gamma-secretase
is mammalian Notch 1. The Notch 1 protein is important for cell
fate determination during development, and tissue homeostasis in
the adult. Upon ligand engagement via the Notch ecto-domain, Notch
undergoes sequential extra-cellular and intra-membrane processing
analogous to APP. The intra-membrane processing of Notch mediated
by gamma secretase leads to release of the Notch intracellular
domain (NICD). The NICD fragment mediates Notch signaling via
translocation to the nucleus, where it regulates expression of
genes mediating cellular differentiation in many tissues during
development, as well as in the adult.
[0015] Disruption of Notch signaling via genetic knock-out (KO)
results in embryonic lethal phenotype in mice (Swiatek, P. J., C.
E. Lindsell, F. F. del Amo, G. Weinmaster and T. Gridley (1994).
"Notch1 is essential for postimplantation development in mice."
Genes Dev 8(6): 707-19; Conlon, R. A., A. G. Reaume and J. Rossant
(1995). "Notch1 is required for the coordinate segmentation of
somites." Development 121(5): 1533-45.) The Notch KO phenotype is
very similar to the phenotype observed PSI KO mice, and precisely
reproduced by PS1/PS2 double KO mice (De Strooper et al. (1998).
"Deficiency of presenilin-1 inhibits the normal cleavage of amyloid
precursor protein." Nature 391(6665): 387-90; Donoviel, D. B., A.
K. Hadjantonakis, M. Ikeda, H. Zheng, P. S. Hyslop and A. Bernstein
(1999). "Mice lacking both presenilin genes exhibit early embryonic
patterning defects." Genes Dev 13(21): 2801-10; Herreman, A., L.
Serneels, W. Annaert, D. Collen, L. Schoonjans and B. De Strooper
(2000). "Total inactivation of gamma-secretase activity in
presenilin-deficient embryonic stem cells." Nat Cell Biol 2(7):
461-2.) This convergence of phenotypes observed in knock-out mice
of either the substrate (Notch) or the enzyme (PS) suggests that
inhibitors of gamma secretase that also inhibit Notch function may
be limited as therapeutic agents owing to the importance of Notch
function in adult tissues (Fortini, M. E. (2002).
"Gamma-secretase-mediated proteolysis in cell-surface-receptor
signaling." Nat Rev Mol Cell Biol 3(9): 673-84.) As APP knock-out
mice develop normally and without an overt phenotype Zheng, H., M.
Jiang, M. E. Trumbauer, R. Hopkins, D. J. Sirinathsinghji, K. A.
Stevens, M. W. Conner, H. H. Slunt, S. S. Sisodia, H. Y. Chen et
al. (1996). "Mice deficient for the amyloid precursor protein
gene." Ann N Y Acad Sci 777: 421-6; Zheng, H., M. Jiang, M. E.
Trumbauer, D. J. Sirinathsinghji, R. Hopkins, D. W. Smith, R. P.
Heavens, G. R. Dawson, S. Boyce, M. W. Conner et al. (1995).
"beta-Amyloid precursor protein-deficient mice show reactive
gliosis and decreased locomotor activity." Cell 81(4): 525-31, the
cumulative evidence, therefore, suggests that preferred gamma
secretase inhibitors would have selectivity for inhibiting gamma
secretase processing of APP over gamma secretase processing of
Notch.

[0416] Definitions
[0417] The definitions and explanations below are for the terms as
used throughout this entire document including both the
specification and the claims. Throughout the specification and the
appended claims, a given formula or name shall encompass all
isomers thereof, such as stereoisomers, geometrical isomers,
optical isomers, tautomers, and mixtures thereof where such isomers
exist, as well as pharmaceutically acceptable salts and solvates
thereof, such as for instance hydrates.
[0418] It should be noted that, as used in this specification and
the appended claims, the singular forms "a," "an," and "the"
include plural referents unless the content clearly dictates
otherwise. Thus, for example, reference to a composition containing
"a compound" includes a mixture of two or more compounds. It should
also be noted that the term "or" is generally employed in its sense
including "and/or" unless the content clearly dictates
otherwise.
[0419] Where multiple substituents are indicated as being attached
to a structure, it is to be understood that the substituents can be
the same or different. Thus for example "R.sub.m optionally
substituted with 1, 2 or 3 R.sub.q groups" indicates that R.sub.m
is substituted with 1, 2, 3, or 4 R.sub.q groups where the R.sub.q
groups can be the same or different. It will be understood by those
skilled in the art with respect to any group containing one or more
substituents that such groups are not intended to introduce any
substitution or substitution patterns that are sterically
impractical and/or synthetically non-feasable.

[0439] Most compounds were named using Autonom 2000 4.01.305, which
is available from Beilstein Information Systems, Inc, Englewood,
Colo., or ChemDraw v.10.0, (available from Cambridgesoft at 100
Cambridge Park Drive, Cambridge, Mass. 02140). Alternatively, the
names were generated based on the IUPAC rules.
[0440] The compounds of this invention may contain one or more
asymmetric carbon atoms, so that the compounds can exist in
different stereoisomeric forms. These compounds can be, for
example, racemates, chiral non-racemic or diastereomers. In these
situations, the single enantiomers, i.e., optically active forms
can be obtained by asymmetric synthesis or by resolution of the
racemates. Resolution of the racemates can be accomplished, for
example, by conventional methods such as crystallization in the
presence of a resolving agent; chromatography, using, for example a
chiral HPLC column; or derivatizing the racemic mixture with a
resolving reagent to generate diastereomers, separating the
diastereomers via chromatography, and removing the resolving agent
to generate the original compound in enantiomerically enriched
form. Any of the above procedures can be repeated to increase the
enantiomeric purity of a compound.
[0441] Non-toxic pharmaceutically acceptable salts include, but are
not limited to salts of inorganic acids such as hydrochloric,
sulfuric, phosphoric, diphosphoric, hydrobromic, and nitric or
salts of organic acids such as formic, citric, malic, maleic,

non-toxic pharmaceutically acceptable addition salts. The invention
also encompasses prodrugs of the compounds of Formula I.
[0442] The invention also encompasses the acylated prodrugs of the
compounds of Formula I. Those skilled in the art will recognize
various synthetic methodologies, which may be employed to prepare
non-toxic pharmaceutically acceptable addition salts and acylated
prodrugs of the compounds encompassed by Formula I.
[0443] The term "acid prodrug group" denotes a moiety that is
converted in vivo into an active carboxylic acid compound of
formula I. Such prodrug groups are generally known in the art and
include ester forming groups, to form an ester prodrug, such as
benzyloxy, di(C.sub.1-C.sub.6)alkylaminoethyloxy, acetoxymethyl,
pivaloyloxymethyl, phthalidoyl, ethoxycarbonyloxyethyl,
5-methyl-2-oxo-1,3-dioxo1-4-ylmethyl, and (C.sub.1-C.sub.6)alkoxy
optionally substituted by N-morpholino and amide-forming groups
such as di(C.sub.1-C.sub.6)alkylamino. Preferred prodrug groups
include C.sub.1-C.sub.6 alkoxy forming an ester, and O.sup.-M.sup.+
where M.sup.+ represents a cation to form a salt of the acid.
Preferred cations include sodium, potassium, and ammonium. Other
cations include magnesium and calcium. Further preferred prodrug
groups include O.sup.=M.sup.++ where M.sup.++ is a divalent cation
such as magnesium or calcium.
[0444] When the compounds described herein contain olefinic double
bonds or other centers of geometric asymmetry, and unless otherwise
specified, it is intended that the compounds include the cis,
trans, Z- and E-configurations. Likewise, all tautomeric forms are
also intended to be included.
[0445] The invention also encompasses the prodrugs of the compounds
of Formula I. Those skilled in the art will recognize various
synthetic methodologies that may be employed to prepare non-toxic
pharmaceutically acceptable prodrugs of the compounds encompassed
by Formula I. Those skilled in the art will recognize a wide
variety of non-toxic pharmaceutically acceptable solvates, such as
water, ethanol, mineral oil, vegetable oil, and
dimethylsulfoxide.
[0446] The compounds of general Formula I may be administered
orally, topically, parenterally, by inhalation or spray or rectally
in dosage unit formulations containing conventional non-toxic
pharmaceutically acceptable carriers, adjuvants and vehicles. The
term parenteral as used herein includes percutaneous, subcutaneous,
intravascular (e.g., intravenous), intramuscular, or intrathecal
injection or infusion techniques and the like. In addition, there
is provided a pharmaceutical formulation comprising a compound of
general Formula I and a pharmaceutically acceptable carrier. One or
more compounds of general Formula I may be present in association
with one or more non-toxic pharmaceutically acceptable carriers
and/or diluents and/or adjuvants, and if desired other active
ingredients. The pharmaceutical compositions containing compounds
of general Formula I may be in a form suitable for oral use, for
example, as tablets, troches, lozenges, aqueous or oily
suspensions, dispersible powders or granules, emulsion, hard or
soft capsules, or syrups or elixirs.
[0447] Compositions intended for oral use may be prepared according
to any method known to the art for the manufacture of
pharmaceutical compositions and such compositions may contain one
or more agents selected from the group consisting of sweetening
agents, flavoring agents, coloring agents and preservative agents
in order to provide pharmaceutically elegant and palatable
preparations. Tablets contain the active ingredient in admixture
with non-toxic pharmaceutically acceptable excipients that are
suitable for the manufacture of tablets. These excipients may be
for example, inert diluents, such as calcium carbonate, sodium
carbonate, lactose, calcium phosphate or sodium phosphate;
granulating and disintegrating agents, for example, corn starch, or
alginic acid; binding agents, for example starch, gelatin or
acacia, and lubricating agents, for example magnesium stearate,
stearic acid or talc. The tablets may be uncoated or they may be
coated by known techniques. In some cases such coatings may be
prepared by known techniques to delay disintegration and absorption
in the gastrointestinal tract and thereby provide a sustained
action over a longer period. For example, a time delay material
such as glyceryl monosterate or glyceryl distearate may be
employed.
[0448] Formulations for oral use may also be presented as hard
gelatin capsules, wherein the active ingredient is mixed with an
inert solid diluent, for example, calcium carbonate, calcium
phosphate or kaolin, or as soft gelatin capsules wherein the active
ingredient is mixed with water or an oil medium, for example peanut
oil, liquid paraffin or olive oil.
[0449] Formulations for oral use may also be presented as
lozenges.
[0450] Aqueous suspensions contain the active materials in
admixture with excipients suitable for the manufacture of aqueous
suspensions. Such excipients are suspending agents, for example
sodium carboxymethylcellulose, methylcellulose,
hydropropyl-methylcellulose, sodium alginate, polyvinylpyrrolidone,
gum tragacanth and gum acacia; dispersing or wetting agents may be
a naturally-occurring phosphatide, for example, lecithin, or
condensation products of an alkylene oxide with fatty acids, for
example polyoxyethylene stearate, or condensation products of
ethylene oxide with long chain aliphatic alcohols, for example
heptadecaethyleneoxycetanol, or condensation products of ethylene
oxide with partial esters derived from fatty acids and a hexitol
such as polyoxyethylene sorbitol monooleate, or condensation
products of ethylene oxide with partial esters derived from fatty
acids and hexitol anhydrides, for example polyethylene sorbitan
monooleate. The aqueous suspensions may also contain one or more
preservatives, for example ethyl, or n-propyl p-hydroxybenzoate,
one or more coloring agents, one or more flavoring agents, and one
or more sweetening agents, such as sucrose or saccharin.
[0451] Oily suspensions may be formulated by suspending the active
ingredients in a vegetable oil, for example arachis oil, olive oil,
sesame oil or coconut oil, or in a mineral oil such as liquid
paraffin. The oily suspensions may contain a thickening agent, for
example beeswax, hard paraffin or cetyl alcohol. Sweetening agents
and flavoring agents may be added to provide palatable oral
preparations. These compositions may be preserved by the addition
of an anti-oxidant such as ascorbic acid.
[0452] Dispersible powders and granules suitable for preparation of
an aqueous suspension by the addition of water provide the active
ingredient in admixture with a dispersing or wetting agent,
suspending agent and one or more preservatives. Suitable dispersing
or wetting agents or suspending agents are exemplified by those
already mentioned above. Additional excipients, for example
sweetening, flavoring and coloring agents, may also be present.
[0453] Pharmaceutical compositions of the invention may also be in
the form of oil-in-water emulsions. The oily phase may be a
vegetable oil or a mineral oil or mixtures of these. Suitable
emulsifying agents may be naturally-occurring gums, for example gum
acacia or gum tragacanth, naturally-occurring phosphatides, for
example soy bean, lecithin, and esters or partial esters derived
from fatty acids and hexitol, anhydrides, for example sorbitan
monooleate, and condensation products of the said partial esters
with ethylene oxide, for example polyoxyethylene sorbitan
monooleate. The emulsions may also contain sweetening and flavoring
agents.
[0454] Syrups and elixirs may be formulated with sweetening agents,
for example glycerol, propylene glycol, sorbitol, glucose or
sucrose. Such formulations may also contain a demulcent, a
preservative and flavoring and coloring agents. The pharmaceutical
compositions may be in the form of a sterile injectable aqueous or
oleaginous suspension. This suspension may be formulated according
to the known art using those suitable dispersing or wetting agents
and suspending agents that have been mentioned above. The sterile
injectable preparation may also be a sterile injectable solution or
suspension in a non-toxic parentally acceptable diluent or solvent,
for example as a solution in 1,3-butanediol. Among the acceptable
vehicles and solvents that may be employed are water, Ringer's
solution and isotonic sodium chloride solution. In addition,
sterile, fixed oils are conventionally employed as a solvent or
suspending medium. For this purpose any bland fixed oil may be
employed including synthetic mono-or diglycerides. In addition,
fatty acids such as oleic acid find use in the preparation of
injectables.
[0455] The compounds of general Formula I may also be administered
in the form of suppositories, e.g., for rectal administration of
the drug. These compositions can be prepared by mixing the drug
with a suitable non-irritating excipient that is solid at ordinary
temperatures but liquid at the rectal temperature and will
therefore melt in the rectum to release the drug. Such materials
include cocoa butter and polyethylene glycols.
[0456] Compounds of general Formula I may be administered
parenterally in a sterile medium. The drug, depending on the
vehicle and concentration used, can either be suspended or
dissolved in the vehicle. Advantageously, adjuvants such as local
anesthetics, preservatives and buffering agents can be dissolved in
the vehicle.
[0457] For disorders of the eye or other external tissues, e.g.,
mouth and skin, the formulations are preferably applied as a
topical gel, spray, ointment or cream, or as a suppository,
containing the active ingredients in a total amount of, for
example, 0.075 to 30% w/w, preferably 0.2 to 20% w/w and most
preferably 0.4 to 15% w/w. When formulated in an ointment, the
active ingredients may be employed with either paraffinic or a
water-miscible ointment base.
[0458] Alternatively, the active ingredients may be formulated in a
cream with an oil-in-water cream base. If desired, the aqueous
phase of the cream base may include, for example at least 30% w/w
of a polyhydric alcohol such as propylene glycol, butane-1,3-diol,
mannitol, sorbitol, glycerol, polyethylene glycol and mixtures
thereof. The topical formulation may desirably include a compound,
which enhances absorption or penetration of the active ingredient
through the skin or other affected areas. Examples of such dermal
penetration enhancers include dimethylsulfoxide and related
analogs. The compounds of this invention can also be administered
by a transdermal device. Preferably topical administration will be
accomplished using a patch either of the reservoir and porous
membrane type or of a solid matrix variety. In either case, the
active agent is delivered continuously from the reservoir or
microcapsules through a membrane into the active agent permeable
adhesive, which is in contact with the skin or mucosa of the
recipient. If the active agent is absorbed through the skin, a
controlled and predetermined flow of the active agent is
administered to the recipient. In the case of microcapsules, the
encapsulating agent may also function as the membrane. The
transdermal patch may include the compound in a suitable solvent
system with an adhesive system, such as an acrylic emulsion, and a
polyester patch. The oily phase of the emulsions of this invention
may be constituted from known ingredients in a known manner. While
the phase may comprise merely an emulsifier, it may comprise a
mixture of at least one emulsifier with a fat or oil or with both a
fat and an oil. Preferably, a hydrophilic emulsifier is included
together with a lipophilic emulsifier, which acts as a stabilizer.
It is also preferred to include both an oil and a fat. Together,
the emulsifier(s) with or without stabilizer(s) make-up the
so-called emulsifying wax, and the wax together with the oil and
fat make up the so-called emulsifying ointment base, which forms
the oily, dispersed phase of the cream formulations. Emulsifiers
and emulsion stabilizers suitable for use in the formulation of the
invention include Tween 60, Span 80, cetostearyl alcohol, myristyl
alcohol, glyceryl monostearate, and sodium lauryl sulfate, among
others. The choice of suitable oils or fats for the formulation is
based on achieving the desired cosmetic properties, since the
solubility of the active compound in most oils likely to be used in
pharmaceutical emulsion formulations is very low. Thus, the cream
should preferably be a non-greasy, non-staining and washable
product with suitable consistency to avoid leakage from tubes or
other containers. Straight or branched chain, mono- or dibasic
alkyl esters such as di-isoadipate, isocetyl stearate, propylene
glycol diester of coconut fatty acids, isopropyl myristate, decyl
oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate
or a blend of branched chain esters may be used. These may be used
alone or in combination depending on the properties required.
Alternatively, high melting point lipids such as white soft
paraffin and/or liquid paraffin or other mineral oils can be
used.
[0459] Formulations suitable for topical administration to the eye
also include eye drops wherein the active ingredients are dissolved
or suspended in suitable carrier, especially an aqueous solvent for
the active ingredients. The anti-inflammatory active ingredients
are preferably present in such formulations in a concentration of
0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5%
w/w. For therapeutic purposes, the active compounds of this
combination invention are ordinarily combined with one or more
adjuvants appropriate to the indicated route of administration. The
compounds may be admixed with lactose, sucrose, starch powder,
cellulose esters of alkanoic acids, cellulose alkyl esters, talc,
stearic acid, magnesium stearate, magnesium oxide, sodium and
calcium salts of phosphoric and sulfuric acids, gelatin, acacia
gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl
alcohol, and then tableted or encapsulated for convenient
administration. Such capsules or tablets may contain a
controlled-release formulation as may be provided in a dispersion
of active compound in hydroxypropylmethyl cellulose. Formulations
for parenteral administration may be in the form of aqueous or
non-aqueous isotonic sterile injection solutions or suspensions.
These solutions and suspensions may be prepared from sterile
powders or granules having one or more of the carriers or diluents
mentioned for use in the formulations for oral administration. The
compounds may be dissolved in water, polyethylene glycol, propylene
glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil,
benzyl alcohol, sodium chloride, and/or various buffers. Other
adjuvants and modes of administration are well and widely known in
the pharmaceutical art.
[0460] Dosage levels of the order of from about 0.1 mg to about 140
mg per kilogram of body weight per day are useful in the treatment
of the above-indicated conditions (about 0.5 mg to about 7 g per
patient per day). The amount of active ingredient that may be
combined with the carrier materials to produce a single dosage form
will vary depending upon the host treated and the particular mode
of administration. Dosage unit forms will generally contain between
from about 1 mg to about 500 mg of an active ingredient. The daily
dose can be administered in one to four doses per day. In the case
of skin conditions, it may be preferable to apply a topical
preparation of compounds of this invention to the affected area two
to four times a day.
[0461] Formulations suitable for inhalation or insufflation include
solutions and suspensions in pharmaceutically acceptable aqueous or
organic solvents, or mixtures thereof, and powders. The liquid or
solid compositions may contain suitable pharmaceutically acceptable
excipients as describe above. The compositions may be administered
by oral or nasal respiratory route for local or systemic effect.
Compositions may be nebulized by use of inert gases or vaporized,
and breathed directly from the nebulizing/vaporizing device or the
nebulizing device may be attached to a facemask tent or
intermittent positive pressure-breathing machine.
[0462] It will be understood, however, that the specific dose level
for any particular patient will depend upon a variety of factors
including the activity of the specific compound employed, the age,
body weight, general health, sex, diet, time of administration,
route of administration, and rate of excretion, drug combination
and the severity of the particular disease undergoing therapy.
[0463] For administration to non-human animals, the composition may
also be added to the animal feed or drinking water. It may be
convenient to formulate the animal feed and drinking water
compositions so that the animal takes in a therapeutically
appropriate quantity of the composition along with its diet. It may
also be convenient to present the composition as a premix for
addition to the feed or drinking water.
[0464] The disclosures in this document of all articles and
references, including patents, are incorporated herein by reference
in their entirety.
[0465] The invention is illustrated further by the following
examples, which are not to be construed as limiting the invention
in scope or spirit to the specific procedures described in
them.
[0466] The starting materials and various intermediates may be
obtained from commercial sources, prepared from commercially
available compounds, and/or prepared using known synthetic
methods.
[0467] General Synthetic Procedures
[0468] Reagents and solvents obtained from commercial suppliers
were used without further purification unless otherwise stated.
Thin layer chromatography was performed on precoated 0.25 mm silica
gel plates (E. Merck, silica gel 60, F.sub.254). Visualization was
achieved using UV illumination or staining with phosphomolybdic
acid, ninhydrin or other common staining reagents. Flash
chromatography was performed using either a Biotage Flash 40 system
and prepacked silica gel columns or hand packed columns (E. Merck
silica gel 60, 230-400 mesh). Preparatory HPLC was performed on a
Varian Prepstar high performance liquid chromatograph. .sup.1H NMR
spectra were recorded on either a Varian Gemini 300 MHz
spectrometer or a Bruker Avance 300 MHz spectrometer. Chemical
shifts are reported in ppm (.delta.) and were calibrated using the
undeuterated solvent resonance as internal standard. Mass spectra
were recorded on an Agilent series 1100 mass spectrometer connected
to an Agilent series 1100 HPLC.
[0469] Exemplary HPLC Procedures
[0470] High Pressure Liquid Chromatography (HPLC) procedures
employed the following methods.
[0471] Method 1: A20% [B]: 80% [A] to 70% [B]: 30% [A] gradient in
1.75 min, then hold, at 2 mL/min, where [A]=0.1% trifluoroacetic
acid in water; [B]=0.1% trifluoroacetic acid in acetonitrile on a
Phenomenex Luna C18 (2) 4.6 mm X 30 cm column, 3 micron packing,
210 nm detection at 35.degree. C.
[0472] Method 2: An isocratic gradient employing 10-20% EtOH or
isopropanol in hexane on a Chiralcel OD or Chiralcel OJ 2
cm.times.25 cm column, 220 nm detection at rt.
[0473] The compounds of the invention can be prepared using methods
known in the art of organic synthesis. For example, the compounds
of the invention, as well as all intermediates, can be synthesized
by known processes using either solution or solid phase techniques,
as shown below. Representative procedures for preparing compounds
of the invention are outlined in the following schemes.
[0474] Additionally, as will be apparent to those skilled in the
art, conventional protecting groups may be necessary to prevent
certain functional groups from undergoing undesired reactions.
Suitable protecting groups for various functional groups as well as
suitable conditions for protecting and deprotecting particular
functional groups are well known in the art. For example, numerous
protecting groups are described in T. W. Greene and G. M. Wuts,
Protecting Groups in Organic Synthesis, Second Edition, Wiley, New
York, 1991, and references cited therein.

[0475] In Scheme 1, R.sub.10, R.sub.3', R.sub.4, R.sub.3, and
R.sub.11 are as defined in formula 1, and the ketone is converted
to the enamine by refluxing the ketone, an equivalent of acid (such
as 4-toluenesulfonic acid) and an equivalent of a base capable of
forming an enamine, such as pyrrolidine, in a solvent, such as
toluene or a higher boiling hydrocarbon solvent, while removing
water using a Dean Stark trap or other dehydrating means. Following
complete reaction as evidenced by NMR of an aliquot, the enamine is
isolated by washing the toluene based reaction mixture with aqueous
NaHCO.sub.3, and then with sat. NaCl. After drying, the solvent is
removed to afford a product suitable for immediate use in the next
reaction.
[0476] The enamine is converted to the triazole by refluxing the
enamine and an equivalent of an azide, such as benzyl azide which
is illustrated above, (other azides, such as C.sub.1-C.sub.6 alkyl
azides or substituted benzyl azides [with groups such as OMe, halo
or Me, for example], may also be used), in tetrahydrofuran or a
higher boiling ethereal solvent. Following complete reaction as
evidenced by TLC, the triazole is isolated by diluting the THF
based reaction mixture with Et0Ac, followed by washing with 0.5 M
citric acid, then with sat. NaCl, and then the reaction mixture is
dried and filtered. Evaporation of the solvent affords a product,
which is purified by flash chromatography. If desired, The triazole
compound then has the benzyl group removed by stirring with
catalytic Pd/C and excess ammonium formate in methanol or another
higher alcohol. Following complete reaction as evidenced by TLC,
the de-benzylated triazole is isolated after filtering and
concentrating the reaction mixture. If desired, the triazole is
purified using column chromatography or preparative HPLC. The
triazole may then be further manipulated (converted into an amide,
alkylated, sulfonylated, etc.,) using methods known in the art.

added. The resulting mixture is stirred at room temperature
overnight. The mixture is diluted with additional methylene
chloride (50 ml) and washed with sat. NaHCO.sub.3 (twice) and brine
(once). After treatment with MgSO.sub.4 and filtering, the solvent
is removed via rotavapor to give the desired product as a pale

[0480] Of course, when compound 3 is converted into compound 4,
other protecting groups, such as Cbz, or benzyl can be used.
[0481] Compound 4 is converted into compound 5 by treatment with a
strong base in an organic solvent, thereby promoting a Dieckman
cyclization. Suitable strong bases include sodium ethoxide,
potassium tert-butoxide, and lithium diisopropyl amide, KHMDS, and
the like. Suitable organic solvents include ethanol, THF, DMF, and
the like. Isolation of the product is accomplished by
neutralization of the strong base, followed by an extractive
workup. Purification of compound 5 is accomplished by
recrystallization, flash chromatography, or preparative HPLC.
[0482] Compound 5 is converted to the trifluoroacetate salt of
compound 6 by treatment with neat trifluoroacetic acid, followed by
evaporation of the excess acid and any solvent that is present.
[0483] The trifluoroacetate salt of compound 6 is converted to
compound 7 by treatment with a sulfonyl chloride, such as
4-chlorobenzenesulfonyl chloride (which is illustrated above) and
triethylamine in dichloromethane. Compound 7 is isolated by
diluting the reaction mixture with EtOAc, followed by washing the
resulting organic phase with mild aqueous acid and saturated
aqueous NaCl, followed by treatment with a drying agent, filtering
and evaporation of the solvent. Purification of compound 7 is
accomplished by recrystallization, flash chromatography, or
preparative HPLC.
[0484] Compound 7 is converted into compound 8 by treatment with
excess hydrazine in ethanol or a higher boiling alcohol, and
refluxing the mixture. Compound 8 is isolated by evaporating the
excess hydrazine and alcohol solvent. Purification of compound 8 is
accomplished by recrystallization, flash chromatography, or
preparative HPLC.
[0485] Compound 8 is converted into compound 9 by heating in the
presence of phosphorus oxychloride, which can be used as the
solvent. Excess phosphorus oxychloride is removed by evaporation,
and then compound 9 is isolated by dissolution in ethyl acetate and
then washing with a mildly alkaline aqueous solution. Compound 9 is
purified using methods known in the art, or it is used in the
following reaction without purification.
[0486] Compound 9 is converted into compound 10 by stirring in the
presence of catalytic Pd/C and excess ammonium formate while
dissolved in methanol. Following complete conversion of compound 9,
compound 10 is isolated by removal of the Pd/C catalyst by
filtration, and removal of the excess ammonium formate and methanol
solvent by evaporation. Purification of compound 11 is accomplished
by recrystallization, flash chromatography, or preparative
HPLC.
[0487] Certain compounds of this invention are prepared from other
compounds of this invention via-known reactions and functional
group transformations. Examples of such transformations are ester
hydrolysis, amide formation, and reductive alkylation; with
examples of these are described in the preparations below. Starting

in CH.sub.2Cl.sub.2/MeOH (10:1) at -78.degree. C. was added
NaHCO.sub.3 (3.5 g). An excess of ozone was bubbled into this
mixture for 45 min. The resulting mixture was then purged with a
stream of N.sub.2 for 10 min at -78.degree. C. To this reaction
mixture was added PPh.sub.3 (6.6 g, 25 mmol). The reaction mixture
was slowly warmed up to room temperature over 48 h. The reaction
mixture was filtered to remove solid NaHCO.sub.3 and then
concentrated to half of its original volume under reduced pressure.
To this crude mixture was added water (10 mL).
Acetone-1,3-dicarboxylic acid (3.65 g, 25.0 mmol) and sodium

HCl (3 N, 16 mL) and was subsequently added to the stirring
solution of the dialdehyde and the dicarboxylic acid over a 15 min
period. The reaction mixture was stirred for 3 days at room
temperature after which the pH was adjusted to 8 by the addition of
potassium carbonate. The resulting solution was extracted with

hydrate (0.4 mL) with good stirring. The vial was capped and the
reaction mixture was stirred evenly and heated to 120.degree. C.
Upon complete consumption of the ketoester (18-48 h, LC-MS), the
reaction mixture was evaporated under a stream of nitrogen while
being warmed in a 90.degree. C. bath. The brown residue was
dissolved with dichloromethane/isopropanol (4:1) and water. The
organic phase was washed with water, 1% aq NaHSO.sub.4, 1% aq
NaHCO.sub.3 (2.times.), and brine (2.times.), dried
(Na.sub.2SO.sub.4), and evaporated to yield the product as a tan

and R. Kopan (1998). "Notch-1 signalling requires ligand-induced

the mammalian homolog of the Drosophila transcription factor
hairy-enhancer of split (Hes). Transcriptional activation of Hes1
is mediated by de-repression of CBF1/RBPJk upon binding by NICD in
the nucleus. These facts have been exploited to develop a reporter
gene assay for Notch Signaling Hsieh, J. J., T. Henkel, P. Salmon,

[0734] Gamma secretase inhibitors have been observed to block NICD
formation, and inhibit Notch signaling (De Strooper, B., W.
Annaert, P. Cupers, P. Saftig, K. Craessaerts, J. S. Mumm, E. H.
Schroeter, V. Schrijvers, M. S. Wolfe, W. J. Ray et al. (1999). "A
presenilin-1-dependent gamma-secretase-like protease mediates
release of Notch intracellular domain." Nature 398(6727): 518-22).
Due to the importance of Notch signaling in cell fate
determination, and tissue differentiation during both development
and in the adult, inhibition of Notch signaling by gamma secretase
inhibitors is postulated to be a limiting factor in their
therapeutic utility. In order to identify selective gamma secretase
inhibitors, we have employed a reporter gene based Notch signaling
assay using a constitutively active rat Notch1 construct (ZEDN1)
provided by Dr Gerry Weinmaster, who is at the University of
California at Los Angeles (UCLA) as described in Shawber, C., D.
Nofziger, J. J. Hsieh, C. Lindsell, O. Bogler, D. Hayward and G.
Weinmaster (1996). "Notch signaling inhibits muscle cell
differentiation through a CBF1-independent pathway." Development
122(12): 3765-73 in combination with the CBF1 repressible
Luciferase reporter gene 4xwtCBF1Luc (Hsieh, J. J., T. Henkel, P.
Salmon, E. Robey, M. G. Peterson and S. D. Hayward (1996).
"Truncated mammalian Notch1 activates CBF1/RBPJk-repressed genes by
a mechanism resembling that of Epstein-Barr virus EBNA2." Mol Cell
Biol 16(3): 952-9).
[0735] When 4xwtCBF1 Luciferase is co-transfected with
Notch.delta.E (ZEDN1), gamma-secretase cleavage of Notch8E releases
the Notch intracellular domain (NICD), which translocates to the
nucleus and de-represses CBF1 mediated transcriptional repression,
leading to transcription of the Luciferase reporter gene.
Luciferase activity is easily assayed in cell extracts using
commercially available kits. The activity of the reporter gene is
directly correlated with gamma secretase cleavage of Notch.delta.E,
and as such, a reduction in Luciferase activity provides a
convenient measure of inhibition of gamma secretase cleavage of
Notch.delta.E. A comparison of the IC.sub.50 values of compounds
for inhibition of Notch signaling versus inhibition of beta-amyloid
production in 293sw cells is employed to guide in the selection of
compounds that have the desired property of potent inhibition of
beta-amyloid synthesis with minimal inhibition of Notch
Signaling.
[0736] Biological Example
[0737] Gamma-Secretase Assay
[0738] The gamma-secretase APP enzyme assay was designed to measure
the specific proteolytic cleavage of an APP substrate (MBP-C125 Swe
fusion protein) at the A.beta.40 site. The assay used a partially
purified extract of IMR-32 cell membranes as the gamma-secretase
enzyme preparation and a recombinant fusion protein containing the
C-terminal 125 amino acids of the Swedish variant of the APP
(MBP-C125swe) as the substrate. This assay involved two steps
beginning with the enzymatic reaction generating a cleavage product
that was captured with an immobilized antibody specific for the
neo-epitope A.beta.40 site. The captured cleavage product was then
detected in a sandwich ELISA assay with a biotinylated reporter
antibody that is specific to A.beta. (17-28). Streptavidin-linked
alkaline phosphatase was then added that would generate a
fluorescent signal proportional to the amount of cleavage product.
This assay was used to discover small molecule inhibitors of
gamma-secretase.
[0739] Materials and Methods:
[0740] Briefly, a 149 mg/ml solution of BIGCHAP detergent was made
with water at 42.degree. C. and then rotated for 30 minutes at the
same temperature. This warmed solution of BigCHAPS
(N,N-Bis(3-D-gluconamidopropyl)cholamide) detergent was used to
dissolve Brain Extract Type-V (lipid containing a minimum of 40%
phosphatidylethanolamine) from Sigma (St. Louis, Mo.) to a
concentration of 8 mg/ml. This solution containing BigCHAPS and
lipid at 8 mg/ml is than diluted to 0.53 mg/ml lipid with a
pre-warmed solution of Hepes and sodium chloride. This final
solution containing Hepes buffer, sodium chloride. BigCHAPS
detergent and lipid is used to create working solutions of both
gamma-secretase (25 Units) and the MBP-C125 substrate (0.05
mg/ml).
[0741] Gamma-secretase was then added to a 96-well micro-titre
plate and then incubated with various concentrations of inhibitor
for 30 minutes at 37.degree. C. MBPC125 substrate was then added to
initiate the reaction that would run for two hours at 37.degree. C.
The reaction was quenched with the addition of SDS to a final
concentration of 0.1% and then 100 .mu.l of the reaction mixture
was transferred to a capture ELISA plate and incubated overnight at
4.degree. C. Detection of the cleavage product was performed using
a standard sandwich ELISA assay and quantified using a six point
standard curve.
[0742] Results
[0743] The following compounds when tested as described above
exhibited inhibition with an IC.sub.50 in a range of 500 nM-250 nM
(A), in a range of 250 nM-100 nM (B), or of less than 100 nM
(C).
