STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED
RESEARCH AND DEVELOPMENT
[0002] NOT APPLICABLE
BACKGROUND OF THE INVENTION
[0003] The 3-phosphoinositide-dependent protein kinase-1 (PDK1)
includes a 556 amino acid protein, an N-terminal catalytic domain,
and a C-terminal pleckstrin homology (PH) domain that activates
substrate kinases via activation loop phosphorylation (Belham, C.
et al., Curr. Biol., 9, pp. R93-R96, 1999). PDK1 is involved in
regulating the activity of AGC subfamily of protein kinases
(Alessi, D. et al., Biochem. Soc. Trans, 29: 1 (2001)) such as
isoforms of protein kinase B (PKB, also known as AKT), p70
ribosomal S6 kinase (S6K) (Avruch, J. et al., Prog. Mol. Subcell.
Biol., 26: 115, (2001)), p.sup.90 ribosomal S6 kinase (Frodin, M.
et al., EMBO J., 19: 2924-2934, (2000)), and protein kinase C (PKC)
(an 80 kDa enzyme that is recruited to the plasma membrane by
diacylglyccrol and, in many cases, by calcium) (Le Good et al.,
Science 281: 2042-2045 (1998). PDK1 mediated signaling increases in
response to insulin, growth factors, and extracellular matrix cell
binding (integrin signaling) resulting in diverse cellular events
such as cell survival, growth, proliferation and glucose regulation
[(Lawlor, M. A. et al., J. Cell Sci., 114, pp. 2903-2910, 2001),
(Lawlor, M. A. et al., EMBO J., 21, pp. 3728-3738, 2002)]. Elevated
PDK1 signaling has been detected in several cancers resulting from
distinct genetic events such as PTEN mutations or over-expression
of certain key regulatory proteins [(Graff, J. R., Expert Opin.
Ther. Targets, 6, pp. 103-113, 2002), (Brognard, J., et al., Cancer
Res., 61, pp. 3986-3997, 2001)].
[0004] The tumor-suppressor phosphatase with tensin homology (PTEN)
is an important negative regulator of the cell-survival signaling
pathway initiated by phosphatidylinositol 3-kinase (PI3K). The
PDK1/Akt pathway is activated in many cancer via mutations in
Receptor Tyrosine Kinases (RTKs), Ras, PI-3 kinase or PTEN (Cully
et al., Nature Reviews Cancer 6:184-192 (2006)). The potential of
PDK1 inhibitors as anti-cancer compounds was demonstrated by
transfection of a PTEN negative human cancer cell line (U87MG) with
antisense oligonucleotides directed against PDK1. The resulting
decrease in PDK1 protein levels led to a reduction in cellular
proliferation and survival (Flynn, P., et al., Curr. Biol., 10:
1439-1442 (2000)).
[0005] Moreover, currently known inhibitors of PDK1 typically
affect both PDK1 mediated Akt phosphorylation and and PDK1 mediated
PKC phosphorylation thereby raising concerns regarding clinical
side effects. Feldman et al., J. Biol. Chem. 280: 19867-19874
(2005).
[0006] Consequently, there is a great need in the art for effective
inhibitors of PDK1. The present invention fulfills these and other
needs.
BRIEF SUMMARY OF THE INVENTION
[0007] In one aspect, the present invention provides a pyridinonyl
PDK1 inhibitor.
[0008] In another aspect, the present invention provides a method
of decreasing PDK1 catalytic activity. The method includes
contacting a PDK1 with an effective amount of a pyridinonyl PDK1
inhibitor.
[0009] In another aspect, the present invention provides a method
of treating cancer in a subject in need thereof. The method
includes administering to the subject a therapeutically effective
amount of a pyridinonyl PDK1 inhibitor.
[0010] In another aspect, the present invention provides methods
for selectively reducing PDK1 mediated phsophorylation of Akt
relative to phosphorylation of PKC. The method includes contacting
PDK1 with a compound of the present invention in the presence of
Akt and PKC.

phosphorylation of Akt relative to PDK1 mediated phosphorylation of
PKC isoforms using different concentrations of compounds of the
present invention.
[0012] FIG. 2 illustrates selective inhibition of PDK1 mediated
phosphorylation of Akt relative to PDK1 mediated phosphorylation of
PKC isoforms using a compound of the present invention (compound

DETAILED DESCRIPTION OF THE INVENTION
Abbreviations and Definitions
[0013] The abbreviations used herein have their conventional
meaning within the chemical and biological arts. The chemical
structures and formulae set forth herein are constructed according
to the standard rules of chemical valency known in the chemical
arts.
[0014] Where substituent groups are specified by their conventional
chemical formulae, written from left to right, they equally
encompass the chemically identical substituents that would result
from writing the structure from right to left, e.g., --CH.sub.2O--
is equivalent to --OCH.sub.2--.
[0015] The term "alkyl," by itself or as part of another
substituent, means, unless otherwise stated, a straight (i.e.
unbranched) or branched chain, or combination thereof, which may be
fully saturated, mono- or polyunsaturated and can include di- and
multivalent radicals, having the number of carbon atoms designated
(i.e. C.sub.1-C.sub.10 means one to ten carbons). Examples of
saturated hydrocarbon radicals include, but are not limited to,
groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl,
t-butyl, isobutyl, sec-butyl, (cyclohexyl)methyl, homologs and
isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and
the like. An unsaturated alkyl group is one having one or more
double bonds or triple bonds. Examples of unsaturated alkyl groups
include, but are not limited to, vinyl, 2-propenyl crotyl,
2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl,
3-(1,4-pentadienyl), ethynyl, 1- and 3-propynyl, 3-butynyl, and the
higher homologs and isomers. An alkoxy is an alkyl attached to the
remainder of the molecule via an oxygen linker (--O--).
[0016] The term "alkylene" by itself or as part of another
substituent means a divalent radical derived from an alkyl, as
exemplified, but not limited, by
--CH.sub.2CH.sub.2CH.sub.2CH.sub.2--, and further includes those
groups described below as "heteroalkylene." Typically, an alkyl (or
alkylene) group will have from 1 to 24 carbon atoms, with those
groups having 10 or fewer carbon atoms being preferred in the
present invention. A "lower alkyl" or "lower alkylene" is a shorter
chain alkyl or alkylene group, generally having eight or fewer
carbon atoms.
[0017] The term "heteroalkyl," by itself or in combination with
another term, means, unless otherwise stated, a stable straight or
branched chain, or cyclic hydrocarbon radical, or combinations
thereof, consisting of at least one carbon atoms and at least one
heteroatom selected from the group consisting of O, N, P, Si and S,
and wherein the nitrogen and sulfur atoms may optionally be
oxidized and the nitrogen heteroatom may optionally be quaternized.
The heteroatom(s) O, N, P and S and Si may be placed at any
interior position of the heteroalkyl group or at the position at
which the alkyl group is attached to the remainder of the molecule.
Examples include, but are not limited to,
--CH.sub.2--CH.sub.2--O--CH.sub.3,
--CH.sub.2--CH.sub.2--NH--CH.sub.3,
--CH.sub.2--CH.sub.2--N(CH.sub.3)--CH.sub.3,
--CH.sub.2--S--CH.sub.2--CH.sub.3, --CH.sub.2--CH.sub.2,
--S(O)--CH.sub.3, --CH.sub.2--CH.sub.2--S(O).sub.2--CH.sub.3,
--CH.dbd.CH--O--CH.sub.3, --Si(CH.sub.3).sub.3,
--CH.sub.2--CH.dbd.N--OCH.sub.3,
--CH.dbd.CH--N(CH.sub.3)--CH.sub.3, O--CH.sub.3,
--O--CH.sub.2--CH.sub.3, and --CN. Up to two heteroatoms may be
consecutive, such as, for example, --CH.sub.2--NH--OCH.sub.3.
Similarly, the term "heteroalkylene" by itself or as part of
another substituent means a divalent radical derived from
heteroalkyl, as exemplified, but not limited by,
--CH.sub.2--CH.sub.2--S--CH.sub.2--CH.sub.2-- and
--CH.sub.2--S--CH.sub.2--CH.sub.2--NH--CH.sub.2--. For
heteroalkylene groups, heteroatoms can also occupy either or both
of the chain termini (e.g., alkyleneoxy, alkylenedioxy,
alkyleneamino, alkylenediamino, and the like). Still further, for
alkylene and heteroalkylene linking groups, no orientation of the
linking group is implied by the direction in which the formula of
the linking group is written. For example, the formula
--C(O).sub.2R'-- represents both --C(O).sub.2R'-- and
--R'C(O).sub.2--. As described above, heteroalkyl groups, as used
herein, include those groups that are attached to the remainder of
the molecule through a heteroatom, such as --C(O)R', --C(O)NR',
--NR'R'', --OR', --SR', and/or --SO.sub.2R'. Where "heteroalkyl" is
recited, followed by recitations of specific heteroalkyl groups,
such as --NR'R'' or the like, it will be understood that the terms
heteroalkyl and --NR'R'' are not redundant or mutually exclusive.
Rather, the specific heteroalkyl groups are recited to add clarity.
Thus, the term "heteroalkyl" should not be interpreted herein as
excluding specific heteroalkyl groups, such as --NR'R'' or the
like.
[0018] The terms "cycloalkyl" and "heterocycloalkyl," by themselves
or in combination with other terms, represent, unless otherwise
stated, cyclic versions of "alkyl" and "heteroalkyl", respectively.
Additionally, for heterocycloalkyl, a heteroatom can occupy the
position at which the heterocycle is attached to the remainder of
the molecule. Examples of cycloalkyl include, but are not limited
to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl,
1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, and the like. Examples
of heterocycloalkyl include, but are not limited to,
1-(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl,
3-piperidinyl, 4-morpholinyl, 3-morpholinyl, tetrahydrofuran-2-yl,
tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl,
1-piperazinyl, 2-piperazinyl, and the like. A "cycloalkylene" and a
"heterocycloalkylene," alone or as part of another substituent
means a divalent radical derived from a cycloalkyl and
heterocycloalkyl, respectively.
[0019] The terms "halo" or "halogen," by themselves or as part of
another substituent, mean, unless otherwise stated, a fluorine,
chlorine, bromine, or iodine atom. Additionally, terms such as
"haloalkyl," are meant to include monohaloalkyl and polyhaloalkyl.
For example, the term "halo(C.sub.1-C.sub.4)alkyl" is meant to
include, but not be limited to, fluoromethyl, difluoromethyl,
trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl,
3-bromopropyl, and the like.
[0020] The term "acyl" means --C(O)R where R is a substituted or
unsubstituted alkyl, substituted or unsubstituted cycloalkyl,
substituted or unsubstituted heteroalkyl, substituted or
unsubstituted heterocycloalkyl, substituted or unsubstituted aryl
or substituted or unsubstituted heteroaryl.
[0021] The term "aryl" means, unless otherwise stated, a
polyunsaturated, aromatic, hydrocarbon substituent which can be a
single ring or multiple rings (preferably firom 1 to 3 rings) which
are fused together (i.e. a fused ring aryl) or linked covalently. A
fused ring aryl refers to multiple rings fused together wherein at
least one of the fused rings is an aryl ring. The term "heteroaryl"
refers to aryl groups (or rings) that contain from one to four
heteroatoms selected from N, O, and S, wherein the nitrogen and
sulfur atoms are optionally oxidized, and the nitrogen atom(s) are
optionally quaternized. Thus, the term "heteroaryl" includes fused
ring heteroaryl groups (i.e. multiple rings fused together wherein
at least one of the fused rings is a heteroaromatic ring). A
5,6-infused ring heteroarylene refers to two rings fused together,
wherein one ring has 5 members and the other ring has 6 members,
and wherein at least one ring is a heteroaryl ring. Likewise, a
6,6-fused ring heteroarylene refers to two rings fused together,
wherein one ring has 6 members and the other ring has 6 members,
and wherein at least one ring is a heteroaryl ring. And a 6,5-fused
ring heteroarylene refers to two rings fused together, wherein one
ring has 6 members and the other ring has 5 members, and wherein at
least one ring is a heteroaryl ring. A heteroaryl group can be
attached to the remainder of the molecule through a carbon or
heteroatom. Non-limiting examples of aryl and heteroaryl groups
include phenyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1-pyrrolyl,
2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl,
pyrazinyl, 2-oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl,
3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl,
5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl,
3-pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl,
purinyl, 2-benzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl,
2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl.
Substituents for each of the above noted aryl and heteroaryl ring
systems are selected from the group of acceptable substituents
described below. An "arylene" and a "heteroarylene," alone or as
part of another substituent means a divalent radical derived from
an aryl and heteroaryl, respectively.
[0022] For brevity, the term "aryl" when used in combination with
other terms (e.g., aryloxy, arylthioxy, arylalkyl) includes both
aryl and heteroaryl rings as defined above. Thus, the term
"arylalkyl" is meant to include those radicals in which an aryl
group is attached to an alkyl group (e.g., benzyl, phenethyl,
pyridylmethyl and the like) including those alkyl groups in which a
carbon atom (e.g., a methylene group) has been replaced by, for
example, an oxygen atom (e.g., phenoxymethyl, 2-pyridyloxymethyl,
3-(1-naphthyloxy)propyl, and the like).
[0023] The term "oxo" as used herein means an oxygen that is double
bonded to a carbon atom.
[0024] The term "alkylsulfonyl" as used herein means a moiety
having the formula --S(O.sub.2)--R', where R' is an alkyl group as
defined above. R' may have a specified number of carbons (e.g.
"C.sub.1-C.sub.4 alkylsulfonyl").
[0025] Each of the above terms (e.g., "alkyl," "heteroalkyl,"
"aryl" and "heteroaryl") are meant to include both substituted and
unsubstituted forms of the indicated radical. Preferred
substituents for each type of radical are provided below.
[0026] Substituents for the alkyl and heteroalkyl radicals
(including those groups often referred to as alkylene, alkenyl,
heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl,
heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one
or more of a variety of groups selected from, but not limited to:
--OR', .dbd.O, .dbd.NR', .dbd.N--OR', --NR'R'', --SR', -halogen,
--SiR'R''R''', --OC(O)R', --C(O)R', --CO.sub.2R', --CONR'R'',
--OC(O)NR'R'', --NR''C(O)R', --NR'--C(O)NR''R''',
--NR''C(O).sub.2R', --NR--C(NR'R''R''').dbd.NR'''',
--NR--C(NR'R'').dbd.NR''', --S(O)R', --S(O).sub.2R',
--S(O).sub.2NR'R'', --NRSO.sub.2R', --CN and --NO.sub.2 in a number
ranging from zero to (2m'+1), where m' is the total number of
carbon atoms in such radical. R', R'', R''' and R'''' each
preferably independently refer to hydrogen, substituted or
unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl,
substituted or unsubstituted heterocycloalkyl, substituted or
unsubstituted aryl (e.g., aryl substituted with 1-3 halogens),
substituted or unsubstituted alkyl, alkoxy or thioalkoxy groups, or
arylalkyl groups. When a compound of the invention includes more
than one R group, for example, each of the R groups is
independently selected as are each R', R'', R''' and R'''' groups
when more than one of these groups is present. When R' and R'' are
attached to the same nitrogen atom, they can be combined with the
nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For
example, --NR'R'' is meant to include, but not be limited to,
1-pyrrolidinyl and 4-morpholinyl. From the above discussion of
substituents, one of skill in the art will understand that the term
"alkyl" is meant to include groups including carbon atoms bound to
groups other than hydrogen groups, such as haloalkyl (e.g.,
--CF.sub.3 and --CH.sub.2CF.sub.3) and acyl (e.g., --C(O)CH.sub.3,
--C(O)CF.sub.3, --C(O)CH.sub.2OCH.sub.3, and the like).
[0027] Similar to the substituents described for the alkyl radical,
substituents for the aryl and heteroaryl groups are varied and are
selected from, for example: halogen, --OR', --NR'R'', --SR',
-halogen, --SiR'R''R''', --OC(O)R', --C(O)R', --CO.sub.2R',
--CONR'R'', --OC(O)NR'R'', --NR''C(O)R', --NR'--C(O)NR''R''',
--NR''C(O).sub.2R', --NR--C(NR'R''R''').dbd.NR'''',
--NR--C(NR'R'').dbd.NR', --S(O)R', --S(O).sub.2R',
--S(O).sub.2NR'R'', --NRSO.sub.2R', --CN and --NO.sub.2, --R',
--N.sub.3, --CH(Ph).sub.2, fluoro(C.sub.1-C.sub.4)alkoxy, and
fluoro(C.sub.1-C.sub.4)alkyl, in a number ranging from zero to the
total number of open valences on the aromatic ring system; and
where R', R'', R''' and R'''' are preferably independently selected
from hydrogen, substituted or unsubstituted alkyl, substituted or
unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl,
substituted or unsubstituted heterocycloalkyl, substituted or
unsubstituted aryl and substituted or unsubstituted heteroaryl.
When a compound of the invention includes more than one R group,
for example, each of the R groups is independently selected as are
each R', R'', R''' and R'''' groups when more than one of these
groups is present.
[0028] Two of the substituents on adjacent atoms of the aryl or
heteroaryl ring may optionally form a ring of the formula
-T-C(O)--(CRR').sub.q-U-, wherein T and U are independently --NR--,
--O--, --CRR'-- or a single bond, and q is an integer of from 0 to
3. Alternatively, two of the substituents on adjacent atoms of the
aryl or heteroaryl ring may optionally be replaced with a
substituent of the formula -A-(CH.sub.2).sub.r--B--, wherein A and
B are independently --CRR'--, --O--, --NR--, --S--, --S(O)--,
--S(O).sub.2--, --S(O).sub.2NR'-- or a single bond, and r is an
integer of from 1 to 4. One of the single bonds of the new ring so
formed may optionally be replaced with a double bond.
Alternatively, two of the substituents on adjacent atoms of the
aryl or heteroaryl ring may optionally be replaced with a
substituent of the formula --(CRR').sub.s--X'--(C''R''').sub.d--,
where s and d are independently integers of from 0 to 3, and X' is
--O--, --NR'--, --S--, --S(O)--, --S(O).sub.2--, or
--S(O).sub.2NR'--. The substituents R, R', R'' and R''' are
preferably independently selected from hydrogen, substituted or
unsubstituted alkyl, substituted or unsubstituted cycloalkyl,
substituted or unsubstituted heterocycloalkyl, substituted or
unsubstituted aryl, and substituted or unsubstituted
heteroaryl.
[0029] As used herein, the term "heteroatom" or "ring heteroatom"
is meant to include oxygen (O), nitrogen (N), sulfur (S),
phosphorus (P), and silicon (Si).
[0030] A "substituent group," as used herein, means a group
selected from the following moieties:
[0031] (A) --OH, --NH.sub.2, --SH, --CN, --CF.sub.3, --NO.sub.2,
oxo, halogen, unsubstituted alkyl, unsubstituted heteroalkyl,
unsubstituted cycloalkyl, unsubstituted heterocycloalkyl,
unsubstituted aryl, unsubstituted heteroaryl, and
[0032] (B) alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl,
and heteroaryl, substituted with at least one substituent selected
from:
[0033] (i) oxo, --OH, --NH.sub.2, --SH, --CN, --CF.sub.3,
--N.sub.02, halogen, unsubstituted alkyl, unsubstituted
heteroalkyl, unsubstituted cycloalkyl, unsubstituted
heterocycloalkyl, unsubstituted aryl, unsubstituted heteroaryl,
and
[0034] (ii) alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl,
and heteroaryl, substituted with at least one substituent selected
from:
[0035] (a) oxo, --OH, --NH.sub.2, --SH, --CN, --CF.sub.3,
--NO.sub.2, halogen, unsubstituted alkyl, unsubstituted
heteroalkyl, unsubstituted cycloalkyl, unsubstituted
heterocycloalkyl, unsubstituted aryl, unsubstituted heteroaryl,
and
[0036] (b) alkyl, heteroalkyl, cycloalkyl, heterocycloalkyl, aryl,
or heteroaryl, substituted with at least one substituent selected
from oxo, --OH, --NH.sub.2, --SH, --CN, --CF.sub.3, --NO.sub.2,
halogen, unsubstituted alkyl, unsubstituted heteroalkyl,
unsubstituted cycloalkyl, unsubstituted heterocycloalkyl,
unsubstituted aryl, and unsubstituted heteroaryl.
[0037] A "size-limited substituent" or "size-limited substituent
group," as used herein means a group selected from all of the
substituents described above for a "substituent group," wherein
each substituted or unsubstituted alkyl is a substituted or
unsubstituted C.sub.1-C.sub.20 alkyl, each substituted or
unsubstituted heteroalkyl is a substituted or unsubstituted 2 to 20
membered heteroalkyl, each substituted or unsubstituted cycloalkyl
is a substituted or unsubstituted C.sub.4-C.sub.8 cycloalkyl, and
each substituted or unsubstituted heterocycloalkyl is a substituted
or unsubstituted 4 to 8 membered heterocycloalkyl.
[0038] A "lower substituent" or "lower substituent group," as used
herein means a group selected from all of the substituents
described above for a "substituent group," wherein each substituted
or unsubstituted alkyl is a substituted or unsubstituted
C.sub.1-C.sub.8 alkyl, each substituted or unsubstituted
heteroalkyl is a substituted or unsubstituted 2 to 8 membered
heteroalkyl, each substituted or unsubstituted cycloalkyl is a
substituted or unsubstituted C.sub.5-C.sub.7 cycloalkyl, and each
substituted or unsubstituted heterocycloalkyl is a substituted or
unsubstituted 5 to 7 membered heterocycloalkyl.
[0039] The term "pharmaceutically acceptable salts" is meant to
include salts of the active compounds which are prepared with
relatively nontoxic acids or bases, depending on the particular
substituents found on the compounds described herein. When
compounds of the present invention contain relatively acidic
functionalities, base addition salts can be obtained by contacting
the neutral form of such compounds with a sufficient amount of the
desired base, either neat or in a suitable inert solvent. Examples
of pharmaceutically acceptable base addition salts include sodium,
potassium, calcium, ammonium, organic amino, or magnesium salt, or
a similar salt. When compounds of the present invention contain
relatively basic functionalities, acid addition salts can be
obtained by contacting the neutral form of such compounds with a
sufficient amount of the desired acid, either neat or in a suitable
inert solvent. Examples of pharmaceutically acceptable acid
addition salts include those derived from inorganic acids like
hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic,
phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric,
monohydrogensulfuric, hydriodic, or phosphorous acids and the like,
as well as the salts derived from relatively nontoxic organic acids
like acetic, propionic, isobutyric, maleic, malonic, benzoic,
succinic, suberic, fumaric, lactic, mandelic, phthalic,
benzenesulfonic, p-tolylsulfonic, citric, tartaric, oxalic,
methanesulfonic, and the like. Also included are salts of amino
acids such as arginate and the like, and salts of organic acids
like glucuronic or galactunoric acids and the like (see, for
example, Berge et al., "Pharmaceutical Salts", Journal of
Pharmaceutical Science, 1977, 66, 1-19). Certain specific compounds
of the present invention contain both basic and acidic
functionalities that allow the compounds to be converted into
either base or acid addition salts.
[0040] Thus, the compounds of the present invention may exist as
salts, such as with pharmaceutically acceptable acids. The present
invention includes such salts. Examples of such salts include
hydrochlorides, hydrobromides, sulfates, methanesulfonates,
nitrates, maleates, acetates, citrates, fumarates, tartrates (e.g.,
(+)-tartrates, (-)-tartrates or mixtures thereof including racemic
mixtures), succinates, benzoates and salts with amino acids such as
glutamic acid. These salts may be prepared by methods known to
those skilled in the art.
[0041] The neutral forms of the compounds are preferably
regenerated by contacting the salt with a base or acid and
isolating the parent compound in the conventional manner. The
parent form of the compound differs from the various salt forms in
certain physical properties, such as solubility in polar
solvents.
[0042] In addition to salt forms, the present invention provides
compounds, which are in a prodrug form. Prodrugs of the compounds
described herein are those compounds that readily undergo chemical
changes under physiological conditions to provide the compounds of
the present invention. Additionally, prodrugs can be converted to
the compounds of the present invention by chemical or biochemical
methods in an ex vivo environment. For example, prodrugs can be
slowly converted to the compounds of the present invention when
placed in a transdermal patch reservoir with a suitable enzyme or
chemical reagent.
[0043] Certain compounds of the present invention can exist in
unsolvated forms as well as solvated forms, including hydrated
forms. In general, the solvated forms are equivalent to unsolvated
forms and are encompassed within the scope of the present
invention. Certain compounds of the present invention may exist in
multiple crystalline or amorphous forms. In general, all physical
forms are equivalent for the uses contemplated by the present
invention and are intended to be within the scope of the present
invention.
[0044] Certain compounds of the present invention possess
asymmetric carbon atoms (optical centers) or double bonds; the
racemates, diastereomers, tautomers, geometric isomers and
individual isomers are encompassed within the scope of the present
invention. The compounds of the present invention do not include
those which are known in the art to be too unstable to synthesize
and/or isolate.
[0045] The compounds of the present invention may also contain
unnatural proportions of atomic isotopes at one or more of the
atoms that constitute such compounds. For example, the compounds
may be radiolabeled with radioactive isotopes, such as for example
tritium (.sup.3H), iodine-125 (.sup.125I) or carbon-14 (.sup.14C).
All isotopic variations of the compounds of the present invention,
whether radioactive or not, are encompassed within the scope of the
present invention.
[0046] The symbol "" denotes the point of attachment of a chemical
moiety to the remainder of a molecule or chemical formula.

[0081] One skilled in the art will understand that the compound of
Formula (I) may include more than one of a specific R group. Where
more than one of a specific R group is present, each R group is
optionally different. For example, the compound of Formula (I) may
include more than one of R.sup.10, R.sup.11, R.sup.12, R.sup.13,
R.sup.14, R.sup.15, R.sup.16, R.sup.17, R.sup.18, R.sup.19,
R.sup.20 and/or R.sup.21. Where more than one of R.sup.10 is
present, for example, each R.sup.10 is optionally different. The
same would hold true for more than one R.sup.11, R.sup.12,
R.sup.13, R.sup.14, R.sup.15, R.sup.16, R.sup.17, R.sup.18,
R.sup.19, R.sup.20 or R.sup.21.
[0082] In some embodiments, R.sup.1 includes a hydrogen bond donor
and a hydrogen bond acceptor, or L.sup.2-R.sup.1 includes a
hydrogen bond donor and a hydrogen bond acceptor. The distance
between the hydrogen bond donor and the pyridinone amide nitrogen
may be about 7-8 .ANG. when said compound is bound to PDK1. An
exemplary set of coordinates for PDK1 that may be used is 1z5 m.pdb
deposited with the RSCB protein data bank. The distance between the
hydrogen bond acceptor and the pyridinone amide nitrogen may be
about 8.5-9.5 .ANG. when said compound is bound to PDK1. The
determination of the distance between the pyridinone amide nitrogen
and the hydrogen bond acceptor and donor is determined using
computer modeling techniques known in the art. For example,
suitable modeling programs include Macromodel (version 9.1,
Schrodinger LLC, New York, N.Y. 2005) and ICM (version 3.406,
Molsoft LLC, San Diego Calif. 2006).
[0083] In certain embodiments of the compound of Formula (I), the
distance between the hydrogen bond donor and the pyridinone amide
nitrogen is about 7-8 .ANG.. In other embodiments, the compound of
Formula (I) is such that the distance between the hydrogen bond
acceptor and the pyridinone amide nitrogen is about 8.5-9.5 .ANG..
In certain other embodiments, the compound of Formula (I) includes
6 atoms (i.e. at least 6 atoms) between the hydrogen bond donor and
the pyridinone amide nitrogen. The compound of Formula (I) may also
include 8 atoms between the hydrogen bond acceptor and the
pyridinone amide nitrogen. The number of atoms between the hydrogen
bond donor or acceptor and the pyridinone amide nitrogen does not
include the amide nitrogen atom or the hydrogen bond donor or
acceptor. The number of atoms is counted along the shortest path
without regard to cyclic structures. For illustrative purposes, the
below compound includes 4 atoms between the hydrogen bond donor and
the pyridinone amide nitrogen, and 6 atoms between the hydrogen

appropriate combination of generally well known synthetic methods.
Techniques useful in synthesizing the compounds of the invention
are both readily apparent and accessible to those of skill in the
relevant art. The discussion below is offered to illustrate certain
of the diverse methods available for use in assembling the
compounds of the invention. However, the discussion is not intended
to define the scope of reactions or reaction sequences that are
useful in preparing the compounds of the present invention.
##STR00021##
[0117] Compounds having the formula of 7s may be synthesized as

chemistry to couple the amine of Is and the free carboxylic acid of
2s. The activated boronic acid ester 6s is provided by substitution
of the bromine of 5s with the precursor boronic acid ester 4s.

formation chemistry, then reacted with an activated R.sup.1
substituent using standard Suzuki conditions to provide the desired
7s.

III. METHODS
[0120] In another aspect, the present invention provides a method
of decreasing PDK catalytic activity. The method includes
contacting a PDK1 with an effective amount of a pyridinonyl PDK1
inhibitor. Therefore, the present invention further provides a
method of inhibiting PDK1 catalytic activity by contacting a PDK1
with a pyridinonyl PDK inhibitor of the present invention.
[0121] PDK1 catalytic activity, as used herein, refers to PDK1
kinase catalytic activity. Thus, where PDK1 catalytic activity is
decreased, the phosphorylation of a PDK1 substrate (e.g. Akt) is
decreased relative to the phosphorylation rate in the absence of
the pyridinonyl PDK1 inhibitor. In some embodiments, the IC.sub.50
of the pyridinonyl PDK1 inhibitor against PDK1 is less than 1
.mu.M. In other embodiments, the IC.sub.50 of the pyridinonyl PDK1
inhibitor against PDK1 is less than 500 nM. In other embodiments,
the IC.sub.50 of the pyridinonyl PDK11 inhibitor against PDK1 is
less than 100 nM. In other embodiments, the IC.sub.50 of the
pyridinonyl PDK1 inhibitor against PDK1 is less than 10 nM. In
other embodiments, the IC.sub.50 of the pyridinonyl PDK1 inhibitor
against PDK1 is less than 1 nM. In other embodiments, the IC.sub.50
of the pyridinonyl PDK1 inhibitor against PDK1 is from 0.1 nM to 10
.mu.M. In other embodiments, the IC.sub.50 of the pyridinonyl PDK1
inhibitor against PDK1 is from 0.1 nM to 1 .mu.M. In other
embodiments, the IC.sub.50 of the pyridinonyl PDK1 inhibitor
against PDK1 is from 0.1 nM to 100 nM. In other embodiments, the
IC.sub.50 of the pyridinonyl PDK1 inhibitor against PDK1 is from
0.1 nM to 10 nM.
[0122] In another aspect, are useful for the treatment of diseases
and disorders that may be alleviated by inhibiting (i.e.
decreasing) PDK1 catalytic activity (e.g. cancer). By "diseases" is
meant diseases, or disease symptoms. Thus, the present invention
provides a method of treating cancer in a subject in need thereof.
The method includes administering to the subject a therapeutically
effective amount of a pyridinonyl PDK1 inhibitor. The term "cancer"
includes diseases or disorders involving abnormal cell growth
and/or proliferation, such as glioma, thyroid carcinoma, breast
carcinoma, lung cancer (e.g. small-cell lung carcinoma,
non-small-cell lung carcinoma), gastric carcinoma, gastrointestinal
stromal tumors, pancreatic carcinoma, bile duct carcinoma, ovarian
carcinoma, endometrial carcinoma, prostate carcinoma, renal cell
carcinoma, anaplastic large-cell lymphoma, leukemia (e.g. acute
myeloid leukemia, T-cell leukemia, chronic lymphocytic leukemia),
multiple myeloma, malignant mesothelioma, malignant melanoma, colon
cancer (e.g. microsatellite instability-high colorectal
cancer).
[0123] In another aspect, the present invention provides methods
for selectively reducing PDK1 mediated phsophorylation of Akt
relative to phosphorylation of PKC. The method includes contacting
PDK1 with a compound of the present invention in the presence of
Akt and PKC. PDK1 mediated phsophorylation of Akt is reduced
relative to PDK1 mediated phosphorylation of PKC (e.g. PKC isoforms
zeta delta and/or theta). In some embodiments, the PDK1 mediated
phosphorylation of Akt is inhibited at least 5, 10, 50, 100, or
1000 fold relative to the PDK1 mediated phosphorylation of PKC.
Assays for determining the inhibition of PDK1 mediated
phosphorylation of Akt and PKC are provided in the Examples
below.
[0124] In some embodiments, the PDK1 mediated phsophorylation of
Akt is reduced relative to phosphorylation of PKC in a cell. Thus,
the present invention provides methods for selectively reducing
PDK1 mediated phsophorylation of Akt relative to phosphorylation of
PKC in a cell. The method includes contacting the cell with a
compound of the present invention. PDK1 mediated phsophorylation of
Akt is reduced relative to PDK1 mediated phosphorylation of PKC
(e.g. PKC isoforms zeta delta and/or theta). In some embodiments,
the PDK1 mediated phosphorylation of Akt is inhibited at least 5,
10, 50, 100, or 1000 fold relative to the PDK1 mediated
phosphorylation of PKC. Assays for determining the inhibition of
PDK1 mediated phosphorylation of Akt and PKC are provided in the
Examples below. The cell in which PDK1 mediated phsophorylation of
Akt is reduced is typically a mammalian cell, such as a domestic
animal (e.g. cat, dog, hose, cow, etc.) of human.
IV. ASSAYS
[0125] To develop useful PDK1 inhibitors, candidate inhibitors
capable of decreasing PDK1 catalytic activity may be identified in
vitro. The activity of the inhibitor compounds can be assayed
utilizing methods known in the art and/or those methods presented
herein.
[0126] Compounds that decrease PDK1 catalytic activity may be
identified and tested using biologically active PDK1, either
recombinant or naturally occurring. PDK1 can be found in native
cells, isolated in vitro, or co-expressed or expressed in a cell.
Measuring the reduction in the PDK1 catalytic activity in the
presence of an inhibitor relative to the activity in the absence of
the inhibitor may be performed using a variety of methods known in
the art, such as the assay described in Example 44. Other methods
for assaying the activity of PDK1 are known in the art. The
selection of appropriate assay methods is well within the
capabilities of those of skill in the art.
[0127] Once compounds are identified that are capable of reducing
PDK1 catalytic activity, the compounds may be further tested for
their ability to selectively inhibit PDK1 relative to other
enzymes. Inhibition by a compound of the invention is measured
using standard in vitro or in vivo assays such as those well known
in the art or as otherwise described herein.
[0128] Compounds may be further tested in cell models or animal
models for their ability to cause a detectable changes in phenotype
related to PDK1 activity. In addition to cell cultures, animal
models may be used to test inhibitors of PDK1 for their ability to
treat cancer in an animal model.

pharmaceutical compositions comprising a PDK1 inhibitor compound of
the invention or a PDK1 inhibitor compound in combination with a
pharmaceutically acceptable excipient (e.g. carrier).

diastereomers, or pharmaceutically acceptable salts of the
inhibitors disclosed herein. For example, in some embodiments, the
pharmaceutical compositions include a compound of the present
invention and citrate as a pharmaceutically acceptable salt. The
PDK1 inhibitor included in the pharmaceutical composition may be
covalently attached to a carrier moiety, as described above.
Alternatively, the PDK1 inhibitor included in the pharmaceutical
composition is not covalently linked to a carrier moiety.
[0131] A "pharmaceutically suitable carrier," as used herein refers
to pharmaceutical excipients, for example, pharmaceutically,
physiologically, acceptable organic, or inorganic carrier
substances suitable for enteral or parenteral application which do
not deleteriously react with the extract. Suitable pharmaceutically
acceptable carriers include water, salt solutions (such as Ringer's
solution), alcohols, oils, gelatins and carbohydrates such as
lactose, amylose or starch, fatty acid esters,
hydroxymethycellulose, and polyvinyl pyrrolidine. Such preparations
can be sterilized and, if desired, mixed with auxiliary agents such
as lubricants, preservatives, stabilizers, wetting agents,
emulsifiers, salts for influencing osmotic pressure, buffers,
coloring, and/or aromatic substances and the like which do not
deleteriously react with the compounds of the invention.
[0132] The compounds of the invention can be administered alone or
can be coadministered to the patient. Coadministration is meant to
include simultaneous or sequential administration of the compounds
individually or in combination (more than one compound). Thus, the
preparations can also be combined, when desired, with other active
substances (e.g. to reduce metabolic degradation).
[0133] A. Formulations
[0134] The PDK1 inhibitors of the present invention can be prepared
and administered in a wide variety of oral, parenteral and topical
dosage forms. Thus, the compounds of the present invention can be
administered by injection (e.g. intravenously, intramuscularly,
intracutaneously, subcutaneously, intraduodenally, or
intraperitoneally). Also, the compounds described herein can be
administered by inhalation, for example, intranasally.
Additionally, the compounds of the present invention can be
administered transdermally. It is also envisioned that multiple
routes of administration (e.g., intramuscular, oral, transdermal)
can be used to administer the compounds of the invention.
Accordingly, the present invention also provides pharmaceutical
compositions comprising a pharmaceutically acceptable carrier or
excipient and one or more compounds of the invention.
[0135] For preparing pharmaceutical compositions from the compounds
of the present invention, pharmaceutically acceptable carriers can
be either solid or liquid. Solid form preparations include powders,
tablets, pills, capsules, cachets, suppositories, and dispersible
granules. A solid carrier can be one or more substance, which may
also act as diluents, flavoring agents, binders, preservatives,
tablet disintegrating agents, or an encapsulating material.
[0136] In powders, the carrier is a finely divided solid, which is
in a mixture with the finely divided active component. In tablets,
the active component is mixed with the carrier having the necessary
binding properties in suitable proportions and compacted in the
shape and size desired.
[0137] The powders and tablets preferably contain from 5% to 70% of
the active compound. Suitable carriers are magnesium carbonate,
magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch,
gelatin, tragacanth, methylcellulose, sodium
carboxymethylcellulose, a low melting wax, cocoa butter, and the
like. The term "preparation" is intended to include the formulation
of the active compound with encapsulating material as a carrier
providing a capsule in which the active component with or without
other carriers, is surrounded by a carrier, which is thus in
association with it. Similarly, cachets and lozenges are included.
Tablets, powders, capsules, pills, cachets, and lozenges can be
used as solid dosage forms suitable for oral administration.
[0138] For preparing suppositories, a low melting wax, such as a
mixture of fatty acid glycerides or cocoa butter, is first melted
and the active component is dispersed homogeneously therein, as by
stirring. The molten homogeneous mixture is then poured into
convenient sized molds, allowed to cool, and thereby to
solidify.
[0139] Liquid form preparations include solutions, suspensions, and
emulsions, for example, water or water/propylene glycol solutions.
For parenteral injection, liquid preparations can be formulated in
solution in aqueous polyethylene glycol solution.
[0140] When parenteral application is needed or desired,
particularly suitable admixtures for the compounds of the invention
are injectable, sterile solutions, preferably oily or aqueous
solutions, as well as suspensions, emulsions, or implants,
including suppositories. In particular, carriers for parenteral
administration include aqueous solutions of dextrose, saline, pure
water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil,
polyoxyethylene-block polymers, and the like. Ampules are
convenient unit dosages. The compounds of the invention can also be
incorporated into liposomes or administered via transdermal pumps
or patches. Pharmaceutical admixtures suitable for use in the
present invention are include those described, for example, in
Pharmaceutical Sciences (17th Ed., Mack Pub. Co., Easton, Pa.) and
WO 96/05309, the teachings of both of which are hereby incorporated
by reference.
[0141] Aqueous solutions suitable for oral use can be prepared by
dissolving the active component in water and adding suitable
colorants, flavors, stabilizers, and thickening agents as desired.
Aqueous suspensions suitable for oral use can be made by dispersing
the finely divided active component in water with viscous material,
such as natural or synthetic gums, resins, methylcellulose, sodium
carboxymethylcellulose, and other well-known suspending agents.
[0142] Also included are solid form preparations, which are
intended to be converted, shortly before use, to liquid form
preparations for oral administration. Such liquid forms include
solutions, suspensions, and emulsions. These preparations may
contain, in addition to the active component, colorants, flavors,
stabilizers, buffers, artificial and natural sweeteners,
dispersants, thickeners, solubilizing agents, and the like.
[0143] The pharmaceutical preparation is preferably in unit dosage
form. In such form the preparation is subdivided into unit doses
containing appropriate quantities of the active component. The unit
dosage form can be a packaged preparation, the package containing
discrete quantities of preparation, such as packeted tablets,
capsules, and powders in vials or ampoules. Also, the unit dosage
form can be a capsule, tablet, cachet, or lozenge itself, or it can
be the appropriate number of any of these in packaged form.
[0144] The quantity of active component in a unit dose preparation
may be varied or adjusted from 0.1 mg to 10000 mg, more typically
1.0 mg to 1000 mg, most typically 10 mg to 500 mg, according to the
particular application and the potency of the active component. The
composition can, if desired, also contain other compatible
therapeutic agents.
[0145] Some compounds may have limited solubility in water and
therefore may require a surfactant or other appropriate co-solvent
in the composition. Such co-solvents include: Polysorbate 20, 60
and 80; Pluronic F-68, F-84 and P-103; cyclodextrin; and polyoxyl
35 castor oil. Such co-solvents are typically employed at a level
between about 0.01% and about 2% by weight.
[0146] Viscosity greater than that of simple aqueous solutions may
be desirable to decrease variability in dispensing the
formulations, to decrease physical separation of components of a
suspension or emulsion of formulation and/or otherwise to improve
the formulation. Such viscosity building agents include, for
example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl
cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose,
carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin
sulfate and salts thereof, hyaluronic acid and salts thereof,
combinations of the foregoing. Such agents are typically employed
at a level between about 0.01% and about 2% by weight.
[0147] The compositions of the present invention may additionally
include components to provide sustained release and/or comfort.
Such components include high molecular weight, anionic mucomimetic
polymers, gelling polysaccharides and finely-divided drug carrier
substrates. These components are discussed in greater detail in
U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The
entire contents of these patents are incorporated herein by
reference in their entirety for all purposes.
[0148] B. Effective Dosages
[0149] Pharmaceutical compositions provided by the present
invention include compositions wherein the active ingredient is
contained in a therapeutically effective amount, i.e., in an amount
effective to achieve its intended purpose. The actual amount
effective for a particular application will depend, inter alia, on
the condition being treated. For example, when administered in
methods to treat cancer, such compositions will contain an amount
of active ingredient effective to achieve the desired result (e.g.
decreasing the number of cancer cells in a subject).
[0150] The dosage and frequency (single or multiple doses) of
administered to a mammal can vary depending upon a variety of
factors, including a disease that results in increased activity of
PDK1, whether the mammal suffers from another disease, and its
route of administration; size, age, sex, health, body weight, body
mass index, and diet of the recipient; nature and extent of
symptoms of the disease being treated (e.g., cancer), kind of
concurrent treatment, complications from the disease being treated
or other health-related problems. Other therapeutic regimens or
agents can be used in conjunction with the methods and compounds of
the invention.
[0151] For any compound described herein, the therapeutically
effective amount can be initially determined from cell culture
assays. Target concentrations will be those concentrations of
active compound(s) that are capable of reducing the activity of
PDK1 catalytic activity, as measured, for example, using the
methods described.
[0152] Therapeutically effective amounts for use in humans may be
determined from animal models. For example, a dose for humans can
be formulated to achieve a concentration that has been found to be
effective in animals. The dosage in humans can be adjusted by
monitoring PDK1 inhibition and adjusting the dosage upwards or
downwards, as described above.
[0153] Dosages may be varied depending upon the requirements of the
patient and the compound being employed. The dose administered to a
patient, in the context of the present invention, should be
sufficient to effect a beneficial therapeutic response in the
patient over time. The size of the dose also will be determined by
the existence, nature, and extent of any adverse side-effects.
Generally, treatment is initiated with smaller dosages which are
less than the optimum dose of the compound. Thereafter, the dosage
is increased by small increments until the optimum effect under
circumstances is reached. In one embodiment of the invention, the
dosage range is 0.001% to 10% w/v. In another embodiment, the
dosage range is 0.1% to 5% w/v.
[0154] Dosage amounts and intervals can be adjusted individually to
provide levels of the administered compound effective for the
particular clinical indication being treated. This will provide a
therapeutic regimen that is commensurate with the severity of the
individual's disease state.
[0155] Utilizing the teachings provided herein, an effective
prophylactic or therapeutic treatment regimen can be planned which
does not cause substantial toxicity and yet is entirely effective
to treat the clinical symptoms demonstrated by the particular
patient. This planning should involve the careful choice of active
compound by considering factors such as compound potency, relative
bioavailability, patient body weight, presence and severity of
adverse side effects, preferred mode of administration and the
toxicity profile of the selected agent.
[0156] C. Toxicity
[0157] The ratio between toxicity and therapeutic effect for a
particular compound is its therapeutic index and can be expressed
as the ratio between LD.sub.50 (the amount of compound lethal in
50% of the population) and EDso (the amount of compound effective
in 50% of the population). Compounds that exhibit high therapeutic
indices are preferred. Therapeutic index data obtained from cell
culture assays and/or animal studies can be used in formulating a
range of dosages for use in humans. The dosage of such compounds
preferably lies within a range of plasma concentrations that
include the EDso with little or no toxicity. The dosage may vary
within this range depending upon the dosage form employed and the
route of administration utilized. See, e.g. Fingl el al., In: THE
PHARMACOLOGICAL BASIS OF THERAPEUTICS, Ch. 1, p. 1, 1975. The exact
formulation, route of administration and dosage can be chosen by
the individual physician in view of the patient's condition and the
particular method in which the compound is used.

(Cell Signaling) in TTBS plus 5% milk. Membranes were washed again
and proteins were visualized with Super Signal West Pico (Pierce,
Rockford, Ill.) and using Kodak BioMax MR film (Kodak, Rochester,
N.Y.).
[0907] Phospho-akt 308 protein bands on the film were quantified
using densitometry. An Alpha Imager (Alpha Innotech Corp, San
Leandro, Calif.) using AlphaEase FC software version 4.1.0 (Alpha
Innotech Corp.) was used to quantitate protein bands. Briefly, a
rectangle of equal size was placed around each protein band as well
as a background spot on the film. The denisitometry values
(IDV=Integrated Density Value) obtained for the background spot was
then subtracted firom the values obtained for the protein bands.
These values were used to obtain an EC50 value using non-linear
regression analysis in GraphPad Prism Version 4.00 (Graph Pad
Prism, San Diego, Calif.). Percent decrease in expression of
phospoh-akt 308 were also measured specifically at 2 M and 5 M
levels of inhibitor.
[0908] Results are set forth in Tables 2 and 3.
Example 198
[0909] Determination of EC50s for the inhibition of phospho-akt
(Thr308) was accomplished by treating PC-3 cells with subject
inhibitors for 2 hours in no serum then using the Meso Scale
Discovery (MSD) phospho-akt 308 ELISA kit to detect p-akt (Thr308)
levels.
[0910] PC-3 cells were harvested by trypsin and counted. Cells were
plated in coated 96-well flat bottom plates (plate 15,000
cells/well in 100 ul growth media (10% FBS, 1.times. pen-strep) an
place in an incubator overnight.
[0911] Subject inhibitors were were stocked at at 50 mM, then
diluted to 30 mM (4.8 .mu.l cpd plus 1.6 ul DMSO) in 100% DMSO.
Three-fold dilutions were performed firom 30 mM stock. (4 .mu.l
into 8 ul 100% DMSO). Aliquots of 1.0 .mu.l of inhibitor solution
were transferred into SF Medium (using deep well block).
[0912] Control wells were prepared as follows. For DMSO high
controls, 1.0 .mu.l of 100% DMSO was added into 1.0 ml SF. For low
controls for PC-3 cells, 5 1M of Wortmannin (10 .mu.l of 1 mM
Wortmannin stock was added into 2 ml SF Medium. The supernatant
media was removed and the plate was blotted. 100l of controls/media
or compound/media were added to cells and placed in incubator for 2
hours. The supernatant media was removed and the plate was blotted.
55 .mu.l of the MSD complete lysis buffer was added (10 mls Tris
Lysis buffer, 200 ul protease inhibitor, 100 ul phosphatase
inhibitor 1, and 100 ul phosphatase inhibitor 11). The plate was
placed on a plate shaker for 60 mins at 4 deg.
[0913] MSD plates were blocked for 1 hour by adding 150 .mu.l of
Blocking Solution (3% BSA) to each well. The MSD plates were washed
4.times. with TBST, and 50 .mu.l lysates were transferred to MSD
plate and place on plate shaker shake at 4 degrees O/N, light
shaking (speed 3.5). The plate was washed 4.times. with TBST.
[0914] For detection, the following detection antibody solution was
used: 1 ml Blocking Solution (3% BSA stock, 1% BSA final); 2 mls
TBST; and 91 .mu.l of stock (0.33 uM) detection antibody (final
concentration 10 nM). 25 .mu.l of Ab detection solution was added
to each well. The plate was sealed and incubated 1 hr RT, light
shaking (speed 3.5). The plate was washed 4 times with TBST. 150
.mu.l of Read Buffer was added (5 mls 4.times.MSD Read Buffer+15 ms
water). Finally the plate was read immediately on the MSD plate
reader.
[0915] Materials: PC-3 (cultured in F12K media-Invitrogen
cat#21127-030 plus 10% FBS and IX pen-strep); Mesoscale Discovery
phospho-akt (Thr 308) kit-cat# K151DYD-1 (includes MSD plate, Tris
Wash Buffer, Blocking Solution A, Read buffer, Tris Lysis Buffer,
protease inhibitor, phosphatase inhibitor I, phosphatase inhibitor
II, and detection); Wortmannin-Calbiochem, cat#681675 (1 mM stock,
aliquoted and stored at -20 deg); and 96 well Poly-L-Lysine coated
plates--Becton Dickinson cat#35-4516 (stored at room temp).
[0916] Percent decrease in expression of phospo-akt 308 was also
measured specifically at 1 .mu.M and 10 .mu.M inhibitor levels.
Results are set forth in Tables 2 and 3.
Example 199
[0917] A PDK1 kinase assay was performed as follows. PDK1 (amino
acids 51-360) and AKT2 (amino acids 140-467 fused to PIFtide, amino
acids EEQEMFRDFDYIADW) were expressed as N-terminally tagged GST
fusion proteins in insect cells and purified to greater than 90%
homogeneity. PDK1 protein was divided into two fractions, one of
which was subsequently dephosphorylated. To generate
dephosphorylated PDK1, the PDK1 was reacted with GST-tagged
lambda-phosphatase in vitro. GST was subsequently cleaved
proteolytically for both phosphorylated and dephosphorylated PDK1.
Protein preparations were run on glutathione Sepharose columns to
remove GST and GST-tagged lambda-phosphatase, if present.
Phosphorylated PDK1 and dephosphorylated PDK1 were verified by
mass-spectrometry. Enzyme activity was determined in a coupled
PDK1/AKT/FAM-crosstide assay using either phosphorylated or
unphosphorylated PDK1 and phosphorylation of FAM-crosstide was
determined by standard IMAP protocol (Molecular Devices). For
inhibition studies, compounds were titrated 3-fold in DMSO and
diluted 40-fold into assay buffer (10 mM Tris HCl pH7.2; 10 mM
MgCl.sub.2; 0.01% Triton X-100; 1 mM DTT) containing PDK1, AKT2,
and FAM-crosstide. (final concentrations: 25 nM un-phosphorylated
PDK1 or 0.5 nM phosphorylated PDK1, 30 nM unphosphorylated AKT2,
and 100 nM crosstide substrate). The kinase reaction was initiated
by adding ATP to a final concentration of 24 .mu.M for both forms
of PDK1 and incubated at 25.degree. C. for 30 min. To detect assay
product, the kinase reaction was combined with Progressive Binding
Solution (1:600 Progressive Binding Reagent, 50% Buffer A, 50%
Buffer B, Molecular Devices) in a 1:3 ratio. The mixture was
incubated for 2 hours at 25.degree. C. and the plate was scanned on
an Analyst AD with excitation at 485 nm and emission at 530 nm. The
fluorescence polarization value "P" is defined by the equation
below. The value "mP" is generated by multiplying the P value for
each reaction well by a factor of 1000. The value ".DELTA.mP" for
each well is the mP value for that well minus the mP value for the
average negative control.
P=(Fpar-Fperp)/(Fpar+Fperp) Eq.:
[0918] Where "par" is fluorescence intensity parallel to the
excitation plane; and "perp" is fluorescence intensity
perpendicular to the excitation plane. AmP values were plotted as a
function of compound concentration and the data were analyzed with
a 4-parameter fit using GraphPad Prism software.
[0919] Results of the in vitro tests are presented in Table 2.
Example 200
[0920] The Phospho-PKC Detection was performed using immunoblot
analysis as follows. The cell activity of test compounds, were
assessed using immunoblot analysis for phospho-akt (thr308),
phospho-PKC delta (thr505), phospho-PKC (thr538) and phospho-PKC
zeta (thr410).
[0921] PC-3 prostate cells were plated in a 100 mm tissue culture
dish in FI2K media (Invitrogen, Carlsbad, Calif.) plus 10% FBS
(Invitrogen) and placed in incubator overnight. The stocks of test
compounds were a 50 mM solution in DMSO. For some test compounds a
5 mM solution was made in DMSO then directly diluted (1 .mu.M and 5
.mu.M final concentration) into fresh media with no serum. For
other test compounds the 50 mM stock was directly diluted (10 .mu.M
and 30 .mu.M final concentrations) into fresh media with no serum.
For the control, DMSO was added to media with no serum at a final
concentration of 0.1%. Cells were incubated with compound for 2 hrs
or 18 hrs at 37.degree. C. Cells were harvested and washed in PBS
and subjected to centrifugation at 3,300 rpm for 5 minutes. The
cell pellet was lysed in 150 .mu.l Pierce (Rockford, Ill.) M-PER
lysis buffer plus protease inhibitors and phosphatase inhibitors
(Sigma, St. Louis, Mo.) for 30 minutes on ice followed by
centrifugation at 13,000 rpm for 5 minutes. The protein content of
the supernatant was assayed using DC Protein Assay (BioRad,
Hercules, Calif.). 35 .mu.g of protein was added to 4.times. sample
buffer (Invitrogen) and sample reducer (Invitrogen) and run on a
4-12% NuPage gel (Invitrogen). Proteins were then transferred to
nitrocellulose (Invitrogen). The membrane was blocked in
Tris-buffered saline (Sigma, St. Louis, Mo.) plus 0.1% Tween
(Sigma) (T-TBS) plus 5% blotting grade milk (BioRad) for 60
minutes. Membranes were then incubated in T-TBS plus 5% BSA (Sigma)
plus 1:1000 of either anti-akt, anti-phospho akt (thr 308),
anti-PKC delta, anti-phospho-PKC delta (thr505), anti-PKC theta,
anti-phospho-PKC theta (thr538), anti-PKC zeta and anti-phospho-PKC
zeta (thr410) (all from Cell Signaling Technology, Beverly, Mass.)
overnight at 40.degree. C. Membranes were washed in T-TBS then
incubated in 1:2000 of anti-rabbit-HRP (Cell Signaling) in T-TBS
plus 5% milk. Membranes were washed again and proteins were
visualized with Super Signal West Pico (Pierce) and using Kodak
BioMax MR film (Kodak, Rochester, N.Y.).
[0922] Results are presented in FIG. 1 and FIG. 2 (setting forth
data from Compound 144 in Table 1).

[0923] PDK phosphorylation of two different substrates, AKT and
PKC-PIFtide, was measured in presence of pre-formed phosphoinositol
lipid PIP3 vesicles. 5 nM full-length PDK1 and was incubated with
100 nM substrate (unphosphorylated, full-length AKT2 or
PKC-PIFtide, Invitrogen cat# P2925) in presence of test compound or
DMSO at room temperature for 3 hours. Final buffer conditions were
10 mM Tris pH 7.5 buffer containing 10 mM MgCl2, 0.002% Triton
X-100, 1 mM DTT, 0.2 mg/ml BSA, 10 uM PtdIns(3,4,5)P3 (Matreya,
Inc), 100 uM DOPC:DOPS (Avanti Polar Lipids), and 0.5 uCi
.gamma..sup.33P-ATP (3000 Ci/mmol, Perkin-Elmer.)
[0924] Kinase reactions were stopped with addition of 50 uM
non-labelled ATP and 5 mM EDTA, then acidified with 0.5% final
concentration phosphoric acid. Labeled proteins were collected in
Whatman P81 filter plates and washed with three 150 ul volumes of
0.5% phosphoric acid. 125 uL of Wallac Optiphase `SuperMix`
scintillation fluid (Perkin Elmer) was added, and plates were read
in a Wallac 1450 Microbeta liquid scintillation counter (Perkin
Elmer) according to manufacturer's instructions.
[0925] Lipid vesicles were pre-formed as follows. 15 mg (3 ampules)
DOPC:DOPS was resuspended in 898 ul 10 mM HEPES pH 7.4. 1 mg PIP3
was resuspended in 1000 ul 10 mM HEPES pH 7.4. 964 ul of PIP3 was
mixed with 800 ul DOPC:DOPS and diluted with 18.2 ml 10 mM HEPES pH
7.4 and mixed by vortexing. The lipid mixture was subjected to 5
cycles of freeze/thaw using liquid nitrogen and a 50.degree. C.
water bath. Aliquot of lipids were flash frozen and stored at
-20.degree. C. Results are provided in Table 1 below.
