FIELD OF THE INVENTION
[0002] This invention is directed generally to proteinase (also
known as "protease") inhibitors, and, more particularly, to
aromatic sulfone hydroxarnates (also known as "aromatic sulfone
hydroxamic acids") that, inter alia, inhibit matrix
metalloproteinase (also known as "matrix metalloprotease" or "MMP")
activity and/or aggrecanase activity. This invention also is
directed to compositions of such inhibitors, intermediates for the
syntheses of such inhibitors, methods for making such inhibitors,
and methods for preventing or treating conditions associated with
MMP activity and/or aggrecanase activity, particularly pathological
conditions.
BACKGROUND OF THE INVENTION
[0003] Connective tissue is a required component of all mammals. It
provides rigidity, differentiation, attachments, and, in some
cases, elasticity. Connective tissue components include, for
example, collagen, elastin, proteoglycans, fibronectin, and
laminin. These biochemicals make up (or are components of)
structures, such as skin, bone, teeth, tendon, cartilage, basement
membrane, blood vessels, cornea, and vitreous humor.
[0004] Under normal conditions, connective tissue turnover and/or
repair processes are in equilibrium with connective tissue
production. Degradation of connective tissue is carried out by the
action of proteinases released from resident tissue cells and/or
invading inflammatory or tumor cells.
[0005] Matrix metalloproteinases, a family of zinc-dependent
proteinases, make up a major class of enzymes involved in degrading
connective tissue. Matrix metalloproteinases are divided into
classes, with some members having several different names in common
use. Examples are: MMP-1 (also known as collagenase 1, fibroblast
collagenase, or EC 3.4.24.3); MMP-2 (also known as gelatinase A, 72
kDa gelatinase, basement membrane collagenase, or EC 3.4.24.24),
MMP-3 (also known as stromelysin 1 or EC 3.4.24.17),
proteoglycanase, MMP-7 (also known as matrilysin), MMP-8 (also
known as collagenase II, neutrophil collagenase, or EC 3.4.24.34),
MMP-9 (also known as gelatinase B, 92 kDa gelatinase, or EC
3.4.24.35), MMP-10 (also known as stromelysin 2 or EC 3.4.24.22),
MMP-1 I (also known as stromelysin 3), MMP-12 (also known as
metalloelastase, human macrophage elastase or HME), MMP-13 (also
known as collagenase 111), and MMP-14 (also known as MT1-MMP or
membrane MMP). See, generally, Woessner, J. F., "The Matrix
Metalloprotease Family" in Matrix Metalloproteinases, pp.1-14
(Edited by Parks, W. C. & Mecham, R. P., Academic Press, San
Diego, Calif. 1998).
[0006] Excessive breakdown of connective tissue by MMPs is a
feature of many pathological conditions. Inhibition of MMPs
therefore provides a control mechanism for tissue decomposition to
prevent and/or treat these pathological conditions. Such
pathological conditions generally include, for example, tissue
destruction, fibrotic diseases, pathological matrix weakening,
defective injury repair, cardiovascular diseases, pulmonary
diseases, kidney diseases, liver diseases, ophthalmologic diseases,
and diseases of the central nervous system. Specific examples of
such conditions include, for example, rheumatoid arthritis,
osteoarthritis, septic arthritis, multiple sclerosis, a decubitis
ulcer, corneal ulceration, epidermal ulceration, gastric
ulceration, tumor metastasis, tumor invasion, tumor angiogenesis,
periodontal disease, liver cirrhosis, fibrotic lung disease,
emphysema, otosclerosis, atherosclerosis, proteinuria, coronary
thrombosis, dilated cardiomyopathy, congestive heart failure,
aortic aneurysm, epidermolysis bullosa, bone disease, Alzheimer's
disease, defective injury repair (e.g., weak repairs, adhesions
such as post-surgical adhesions, and scarring), post-myocardial
infarction, bone disease, and chronic obstructive pulmonary
disease.
[0007] Matrix metalloproteinases also are involved in the
biosynthesis of tumor necrosis factors (TNFs). Tumor necrosis
factors are implicated in many pathological conditions.
TNF-.alpha., for example, is a cytokine that is presently thought
to be produced initially as a 28 kD cell-associated molecule. It is
released as an active, 17 kD form that can mediate a large number
of deleterious effects in vitro and in vivo. TNF-.alpha. can cause
and/or contribute to the effects of inflammation (e.g., rheumatoid
arthritis), autoimmune disease, graft rejection, multiple
sclerosis, fibrotic diseases, cancer, infectious diseases (e.g.,
malaria, mycobacterial infection, meningitis, etc.), fever,
psoriasis, cardiovascular diseases (e.g., post-ischemic reperfusion
injury and congestive heart failure), pulmonary diseases,
hemorrhage, coagulation, hyperoxic alveolar injury, radiation
damage, and acute phase responses like those seen with infections
and sepsis and during shock (e.g., septic shock and hemodynamic
shock). Chronic release of active TNF-.alpha. can cause cachexia
and anorexia. TNF-.alpha. also can be lethal.
[0008] Inhibiting TNF (and related compounds) production and action
is an important clinical disease treatment. Matrix
metalloproteinase inhibition is one mechanism that can be used. MMP
(e.g., collagenase, stromelysin, and gelatinase) inhibitors, for
example, have been reported to inhibit TNF-.alpha. release. See,
e.g., Gearing et al. Nature 376, 555-557 (1994). See also, McGeehan
et al. See also, Nature 376, 558-561 (1994). MMP inhibitors also
have been reported to inhibit TNF-.alpha. convertase, a
metalloproteinase involved in forming active TNF-.alpha.. See,
e.g., WIPO Int'l Pub. No. WO 94/24140. See also, WIPO Int'l Pub.
No. WO 94/02466. See also, WIPO Int'l Pub. No. WO 97/20824.
[0009] Matrix metalloproteinases also are involved in other
biochemical processes in mammals. These include control of
ovulation, post-partum uterine involution, possibly implantation,
cleavage of APP (.beta.-amyloid precursor protein) to the ainyloid
plaque, and inactivation of (.alpha..sub.1-protease inhibitor
(.alpha..sub.1-PI). Inhibiting MMPs therefore may be a mechanism
that may be used to control of fertility. In addition, increasing
and maintaining the levels of an endogenous or administered serine
protease inhibitor (e.g., .alpha..sub.1-PI) supports the treatment
and prevention of pathological conditions such as emphysema,
pulmonary diseases, inflammatory diseases, and diseases of aging
(e.g., loss of skin or organ stretch and resiliency).
[0010] Numerous metalloproteinase inhibitors are known. See,
generally, Brown, P. D., "Synthetic Inhibitors of Matrix
Metalloproteinases," in Matrix Metalloproteinases, pp. 243-61
(Edited by Parks, W. C. & Mecham, R. P., Academic Press, San
Diego, Calif. 1998).
[0011] Metalloproteinase inhibitors include, for example, natural
biochemicals, such as tissue inhibitor of metalloproteinase (TIMP),
.alpha.2-macroglobulin, and their analogs and derivatives. These
are high-molecular-weight protein molecules that form inactive
complexes with-metalloproteinases.
[0012] A number of smaller peptide-like compounds also have been
reported to inhibit metalloproteinases. Mercaptoamide peptidyl
derivatives, for example, have been reported to inhibit angiotensin
converting enzyme (also known as ACE) in vitro and in vivo. ACE
aids in the production of angiotensin II, a potent pressor
substance in mammals. Inhibiting ACE leads to lowering of blood
pressure.
[0013] A wide variety of thiol compounds have been reported to
inhibit MMPs. See, e.g., W095/12389. See also, W096/11209. See
also, U.S. Pat. No. 4,595,700. See also, U.S. Pat. No.
6,013,649.
[0014] A wide variety of hydroxamate compounds also have been
reported to inhibit MMPs. Such compounds reportedly include
hydroxamates having a carbon backbone. See, e.g., WIPO Int'l Pub.
No. WO 95/29892. See also, WIPO Int'l Pub. No. WO 97/24117. See
also, WIPO Int'l Pub. No. WO 97/49679. See also, European Patent
No. EP 0 780 386. Such compounds also reportedly include
hydroxamates having peptidyl backbones or peptidomimetic backbones.
See, e.g, WIPO Int'l Pub. No. WO 90/05719. See also, WIPO Int'l
Pub. No. WO 93/20047. See also, WIPO Int'l Pub. No. WO 95/09841.
See also, WIPO Int'l Pub. No. WO 96/06074. See also, Schwartz et
al., Progr. Med. Chem., 29:271-334(1992). See also, Rasmussen et
al., PharmacoL Ther., 75(1): 69-75 (1997). See also, Denis et al.,
Invest New Drugs, 15(3): 175-185 (1997). Various
piperazinylsulfonylmethyl hydroxamates and
piperidinylsulfonylmethyl hydroxamates have additionally been
reported to inhibit MMPs. See, WIPO Int'l Pub. No. WO 00/46221. And
various aromatic sulfone hydroxamates have been reported to inhibit
MMPs. See, WIPO Int'l Pub. No. WO 99/25687. See also, WIPO Int'l
Pub. No. WO 00/50396. See also, WIPO Int'l Pub. No. WO
00/69821.
[0015] It is often advantageous for an MMP inhibitor drug to target
a certain MMP(s) over another MMP(s). For example, it is typically
preferred to inhibit MMP-2, MMP-3, MMP-9, and/or MMP-13
(particularly MMP-13) when treating and/or preventing cancer,
inhibiting of metastasis, and inhibiting angiogenesis. It also is
typically preferred to inhibit MMP-13 when preventing and/or
treating osteoarthritis. See, e.g., Mitchell et al., J Clin.
Invest., 97:761-768 (1996). See also, Reboul et al., J Clin.
Invest., 97:2011-2019 (1996). Normally, however, it is preferred to
use a drug that has little or no inhibitory effect on MMP-1 and
MMP-14. This preference stems from the fact that both MMP-1 and
MMP-14 are involved in several homeostatic processes, and
inhibition of MMP-1 and/or MMP-14 consequently tends to interfere
with such processes.
[0016] Many known MMP inhibitors exhibit the same or similar
inhibitory effects against each of the MMPs. For example,
batimastat (a peptidomimetic hydroxamate) has been reported to
exhibit IC.sub.50 values of from about 1 to about 20 nM against
each of MMP-1, MMP-2, MMP-3, MMP-7, and MMP-9. Marimastat (another
peptidomimetic hydroxamate) has been reported to be another
broad-spectrum MMP inhibitor with an enzyme inhibitory spectrum
similar to batimastat, except that Marimastat reportedly exhibited
an IC.sub.50 value against MMP-3 of 230 nM. See Rasmussen et al.,
Pharmacol. Ther., 75(1): 69-75 (1997).
[0017] Meta analysis of data from Phase I/II studies using
Marimastat in patients with advanced, rapidly progressive,
treatment-refractory solid tumor cancers (colorectal, pancreatic,
ovarian, and prostate) indicated a dose-related reduction in the
rise of cancer-specific antigens used as surrogate markers for
biological activity. Although Marimastat exhibited some measure of
efficacy via these markers, toxic side effects reportedly were
observed. The most common drug-related toxicity of Marimastat in
those clinical trials was musculoskeletal pain and stiffness, often
commencing in the small joints in the hands, and then spreading to
the arms and shoulder. A short dosing holiday of 1-3 weeks followed
by dosage reduction reportedly permits treatment to continue. See
Rasmussen et al., Pharmacol. Ther., 75(1): 69-75 (1997). It is
thought that the lack of specificity of inhibitory effect among the
MMPs may be the cause of that effect.
[0018] Another enzyme implicated in pathological conditions
associated with excessive degradation of connective tissue is
aggrecanase, particularly aggrecanase-1 (also known as ADAMTS-4).
Specifically, articular cartilage contains large amounts of the
proteoglycan aggrecan. Proteoglycan aggrecan provides mechanical
properties that help articular cartilage in withstanding
compressive deformation during joint articulation. The loss of
aggrecan fragments and their release into synovial fluid caused by
proteolytic cleavages is a central pathophysiological event in
osteoarthritis and rheumatoid arthritis. It has been reported that
two major cleavage sites exist in the proteolytically sensitive
interglobular domains at the N-terminal region of the aggrecan core
protein. One of those sites has been reported to be cleaved by
several matrix metalloproteases. The other site, however, has been
reported to be cleaved by aggrecanase-1. Thus, inhibiting excessive
aggrecanase activity provides an additional and/or alternative
prevention or treatment method for inflammatory conditions. See
generally, Tang, B. L., "ADAMTS: A Novel Family of Extracellular
Matrix Proteases," Int 'I Journal of Biochemistry & Cell
Biology, 33, pp. 33-44 (2001). Such diseases reportedly include,
for example, osteoarthritis, rheumatoid arthritis, joint injury,
reactive arthritis, acute pyrophosphate arthritis, and psoriatic
arthritis. See, e.g., European Patent Application Publ. No. EP 1
081 137 A1.
[0019] In addition to inflammatory conditions, there also is
evidence that inhibiting aggrecanase may be used for preventing or
treating cancer. For example, excessive levels of aggrecanase-1
reportedly have been observed with a ghoma cell line. It also has
been postulated that the enzymatic nature of aggrecanase and its
similarities with the MMPs would support tumor invasion,
metastasis, and angiogenesis. See Tang, Int'l Journal of
Biochemistry & Cell Biology, 33, pp. 33-44 (2001).
[0020] Various hydroxamate compounds have been reported to inhibit
aggrecanase-1. Such compounds include, for example, those described
in European Patent Application Publ. No. EP 1 081 137 A1. Such
compounds also include, for example, those described in WIPO PCT
Int'l Publ. No. WO 00/09000. Such compounds further include, for
example, those described in WIPO PCT Int'l Publ. No. WO
00/59874.
[0021] In view of the importance of hydroxamate compounds in the
prevention or treatment of several pathological conditions and the
lack of enzyme specificity exhibited by two of the more potent
MMP-inhibitor drugs that have been in clinical trials, there
continues to be a need for hydroxamates having greater enzyme
specificity (preferably toward MMP-2, MMP-9, MMP-13, and/or
aggrecanase (particularly toward MMP-13 in some instances, toward
both MMP-2 and MMP-9 in other instances, and aggrecanase in yet
other instances), while exhibiting little or no inhibition of MMP-1
and/or MMP-14. The following disclosure describes hydroxamate
compounds that tend to exhibit such desirable activities.
SUMMARY OF THE INVENTION
[0022] This invention is directed to hydroxamate compounds (and
salts thereof) that inhibit pathological protease activity
(particularly compounds that inhibit MMP-2, MMP-9, MMP-13, and/or
aggrecanase activity), while generally exhibiting relatively little
or no inhibition against MMP-1 and MMP-14 activity. This invention
also is directed to a method for inhibiting MMP activity and/or
aggrecanase activity, particularly pathological MMP and/or
aggrecanase activity. Such a method is particularly suitable to be
used with mammals, such as humans, other primates (e.g., monkeys,
chimpanzees. etc.), companion animals (e.g., dogs, cats, horses.
etc.), farm animals (e.g., goats, sheep, pigs, cattle, etc.),
laboratory animals (e.g., mice, rats, etc.), and wild and zoo
animals (e.g., wolves, bears, deer, etc.).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0182] This detailed description of preferred embodiments is
intended only to acquaint others skilled in the art with
Applicants' invention, its principles, and its practical
application so that others skilled in the art may adapt and apply
the invention in its numerous forms, as they may be best suited to
the requirements of a particular use. This detailed description and
its specific examples, while indicating preferred embodiments of
this invention, are intended for purposes of illustration only.
This invention, therefore, is not limited to the preferred
embodiments described in this patent, and may be variously
modified.
A. Compounds of this Invention
[0183] In accordance with this invention, it has been found that
certain aromatic sulfone hydroxamates tend to be effective for
inhibiting MMPs, particularly those associated with excessive (or
otherwise pathological) breakdown of connective tissue.
Specifically, Applicants have found that these hydroxamates tend to
be effective for inhibiting proteases (particularly MMP-2, MMP-9,
MMP-13, other MMP's associated with pathological conditions, and/or
aggrecanase) that are often particularly destructive to tissue if
present or generated in abnormally excessive quantities or
concentrations. Moreover, Applicants have discovered that these
hydroxamates tend to be selective toward inhibiting pathological
protease activity, while avoiding excessive inhibition of other
proteases (particularly MMP-1 and/or MMP-14) that are typically
essential to normal bodily function (e.g., tissue turnover and
repair).

B. Salts of the Compounds of this Invention
[0891] The compounds of this invention can be used in the form of
salts derived from inorganic or organic acids. Depending on the
particular compound, a salt of the compound may be advantageous due
to one or more of the salt's physical properties, such as enhanced
pharmaceutical stability in differing temperatures and humidities,
or a desirable solubility in water or oil. In some instances, a
salt of a compound also may be used as an aid in the isolation,
purification, and/or resolution of the compound.
[0892] Where a salt is intended to be administered to a patient (as
opposed to, for example, being used in an in vitro context), the
salt preferably is pharmaceutically acceptable. Pharmaceutically
acceptable salts include salts commonly used to form alkali metal
salts and to form addition salts of free acids or free bases. In
general, these salts typically may be prepared by conventional
means with a compound of this invention by reacting, for example,
the appropriate acid or base with the compound.

C. Preventing or Treating Conditions Using the Compounds and Salts
of this Invention
[0896] One embodiment of this invention is directed to a process
for preventing or treating a pathological condition associated with
MMP activity in a mammal (e.g., a human, companion animal, farm
animal, laboratory animal, zoo animal, or wild animal) having or
disposed to having such a condition. Such a condition may be, for
example, tissue destruction, a fibrotic disease, pathological
matrix weakening, defective injury repair, a cardiovascular
disease, a pulmonary disease, a kidney disease, a liver disease, an
ophthalmologic disease, or a central nervous system disease.
Specific examples of such conditions include osteoarthritis,
rheumatoid arthritis, septic arthritis, tumor invasion, tumor
metastasis, tumor angiogenesis, a decubitis ulcer, a gastric ulcer,
a corneal ulcer, periodontal disease, liver cirrhosis, fibrotic
lung disease, otosclerosis, atherosclerosis, multiple sclerosis,
dilated cardiomyopathy, epidermal ulceration, epidermolysis
bullosa, aortic aneurysm, weak injury repair, an adhesion,
scarring, congestive heart failure, post myocardial infarction,
coronary thrombosis, emphysema, proteinuria, bone disease, chronic
obstructive pulmonary diseases, and Alzheimer's disease.
[0897] In some particularly preferred embodiments, the condition
comprises arthritis.
[0898] In some particularly preferred embodiments, the condition
comprises tumor invasion, tumor metastasis, or tumor
angiogenesis.
[0899] In some particularly preferred embodiments, the condition
comprises periodontal disease.
[0900] In some particularly preferred embodiments, the condition
comprises atherosclerosis.
[0901] In some particularly preferred embodiments, the condition
comprises multiple sclerosis.
[0902] In some particularly preferred embodiments, the condition
comprises dilated cardiomyopathy.
[0903] In some particularly preferred embodiments, the condition
comprises post myocardial infarction.
[0904] In some particularly preferred embodiments, the condition
comprises congestive heart failure.
[0905] In some particularly preferred embodiments, the condition
comprises chronic obstructive pulmonary disease.
[0906] The condition may alternatively (or additionally) be
associated with TNF-.alpha. convertase activity. Examples of such a
condition include inflammation (e.g., rheumatoid arthritis),
autoimmune disease, graft rejection, multiple sclerosis, a fibrotic
disease, cancer, an infectious disease (e.g., malaria,
mycobacterial infection, meningitis, etc.), fever, psoriasis, a
cardiovascular disease (e.g., post-ischemic reperfusion injury and
congestive heart failure), a pulmonary disease, hemorrhage,
coagulation, hyperoxic alveolar injury, radiation damage, acute
phase responses like those seen with infections and sepsis and
during shock (e.g., septic shock, hemodynamic shock, etc.),
cachexia, and anorexia.
[0907] The condition may alternatively (or additionally) be
associated with aggrecanase activity. Examples of such a condition
include inflammation diseases (e.g., osteoarthritis, rheumatoid
arthritis, joint injury, reactive arthritis, acute pyrophosphate
arthritis, and psoriatic arthritis) and cancer.
[0908] In this patent, the phrase "preventing a condition" means
reducing the risk of (or delaying) the onset of the condition in a
mammal that does not have the condition, but is predisposed to
having the condition. In contrast, the phrase "treating a
condition" means ameliorating, suppressing, or eradicating an
existing condition. The pathological condition may be (a) the
result of pathological MMP activity itself, and/or (b) affected by
MMP activity (e.g., diseases associated with TNF-.alpha.).
[0909] A wide variety of methods may be used alone or in
combination to administer the hydroxamates and salt thereof
described above. For example, the hydroxamates or salts thereof may
be administered orally, parenterally, by inhalation spray,
rectally, or topically.
[0910] Typically, a compound (or pharmaceutically acceptable salt
thereof) described in this patent is administered in an amount
effective to inhibit a target MMP(s). The target MMP is/are
typically MMP-2, MMP-9, and/or MMP-13, with MMP-13 often being a
particularly preferred target. The preferred total daily dose of
the hydroxamate or salt thereof (administered in single or divided
doses) is typically from about 0.001 to about 100 mg/kg, more
preferably from about 0.001 to about 30 mg/kg, and even more
preferably from about 0.01 to about 10 mg/kg (i.e., mg hydroxamate
or salt thereof per kg body weight). Dosage unit compositions can
contain such amounts or submultiples thereof to make up the daily
dose. In many instances, the administration of the compound or salt
will be repeated a plurality of times. Multiple doses per day
typically may be used to increase the total daily dose, if
desired.
[0911] Factors affecting the preferred dosage regimen include the
type, age, weight, sex, diet, and condition of the patient; the
severity of the pathological condition; the route of
administration; pharmacological considerations, such as the
activity, efficacy, pharmacokinetic, and toxicology profiles of the
particular hydroxamate or salt thereof employed; whether a drug
delivery system is utilized; and whether the hydroxamate or salt
thereof is administered as part of a drug combination. Thus, the
dosage regimen actually employed can vary widely, and, therefore,
can deviate from the preferred dosage regimen set forth above.
D. Pharmaceutical Compositions Containing the Compounds and Salts
of this Invention
[0912] This invention also is directed to pharmaceutical
compositions comprising a hydroxamate or salt thereof described
above, and to methods for making pharmaceutical compositions (or
medicaments) comprising a hydroxamate or salt thereof described
above.
[0913] The preferred composition depends on the method of
administration, and typically comprises one or more conventional
pharmaceutically acceptable carriers, adjuvants, and/or vehicles.
Formulation of drugs is generally discussed in, for example,
Hoover, John E., Remington's Pharmaceutical Sciences (Mack
Publishing Co., Easton, Pa.: 1975). See also, Liberman, H. A. See
also, Lachman, L., eds., Pharmaceutical Dosage Forms (Marcel
Decker, New York, N.Y., 1980).
[0914] Solid dosage forms for oral administration include, for
example, capsules, tablets, pills, powders, and granules. In such
solid dosage forms, the hydroxamates or salts thereof are
ordinarily combined with one or more adjuvants. If administered per
os, the hydroxamates or salts thereof can be mixed 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 can contain a controlled-release formulation, as can be
provided in a dispersion of the hydroxamate or salt thereof in
hydroxypropylmethyl cellulose. In the case of capsules, tablets,
and pills, the dosage forms also can comprise buffering agents,
such as sodium citrate, or magnesium or calcium carbonate or
bicarbonate. Tablets and pills additionally can be prepared with
enteric coatings.
[0915] Liquid dosage forms for oral administration include, for
example, pharmaceutically acceptable emulsions, solutions,
suspensions, syrups, and elixirs containing inert diluents commonly
used in the art (e.g., water). Such compositions also can comprise
adjuvants, such as wetting, emulsifying, suspending, flavoring
(e.g., sweetening), and/or perfuming agents.
[0916] "Parenteral administration" includes subcutaneous
injections, intravenous injections, intramuscular injections,
intrasternal injections, and infusion. Injectable preparations
(e.g., sterile injectable aqueous or oleaginous suspensions) can be
formulated according to the known art using suitable dispersing,
wetting agents, and/or suspending agents. Acceptable vehicles and
solvents include, for example, water, 1,3-butanediol, Ringer's
solution, isotonic sodium chloride solution, bland fixed oils
(e.g., synthetic mono- or diglycerides), fatty acids (e.g., oleic
acid), dimethyl acetamide, surfactants (e.g., ionic and non-ionic
detergents), and/or polyethylene glycols.
[0917] Formulations for parenteral administration may, for example,
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 hydroxamates or salts thereof can 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.
[0918] Suppositories for rectal administration can be prepared by,
for example, mixing the drug with a suitable nonirritating
excipient that is solid at ordinary temperatures, but liquid at the
rectal temperature and will therefore melt in the rectum to release
the drug. Suitable excipients include, for example, such as cocoa
butter; synthetic mono-, di-, or triglycerides; fatty acids; and/or
polyethylene glycols
[0919] "Topical administration" includes the use of transdermal
administration, such as transdermal patches or iontophoresis
devices.
[0920] Other adjuvants and modes of administration well-known in
the pharmaceutical art may also be used.

and indenyl.
[0927] In some instances, the number of carbon atoms in a
hydrocarbyl (e.g., alkyl, alkenyl, alkynyl, or cycloalkyl) is
indicated by the prefix "C.sub.x-C.sub.y-", wherein x is the
minimum and y is the maximum number of carbon atoms in the
substituent. Thus, for example, "C.sub.1-C.sub.6-alkyl" refers to
an alkyl containing from 1 to 6 carbon atoms. Illustrating further,

of the hydrogen radicals is replaced by a non-hydrogen substituent.
The term "disubstituted amino" (alone or in combination with
another term(s)) means an amino wherein both of the hydrogen atoms
are replaced by non-hydrogen substituents, which may be identical
or different.
[0935] The term "halogen" (alone or in combination with another
term(s)) means a fluorine radical (which may be depicted as --F),
chlorine radical (which may be depicted as --Cl), bromine radical
(which may be depicted as --Br), or iodine radical (which may be
depicted as --I). Typically, a fluorine radical or chlorine radical
is preferred, with a fluorine radical often being particularly
preferred.
[0936] If a substituent is described as being "substituted", a
non-hydrogen radical is in the place of a hydrogen radical on a
carbon or nitrogen of the substituent. Thus, for example, a
substituted alkyl substituent is an alkyl substituent wherein at
least one non-hydrogen radical is in the place of a hydrogen
radical on the alkyl substituent. To illustrate, monofluoroalkyl is
alkyl substituted with a fluoro radical, and difluoroalkyl is alkyl
substituted with two fluoro radicals. It should be recognized that
if there are more than one substitutions on a substituent, each
non-hydrogen radical may be identical or different (unless
otherwise stated).
[0937] If a substituent is described as being "optionally
substituted", the substituent may be either (1) substituted, or (2)
not substituted.
[0938] This specification uses the terms "substituent" and
"radical" interchangeably.
[0939] The prefix "halo" indicates that the substituent to which
the prefix is attached is substituted with one or more
independently selected halogen radicals. For example, haloalkyl
means an alkyl wherein at least one hydrogen radical is replaced
with a halogen radical. Examples of haloalkyls include
chloromethyl, 1-bromoethyl, fluoromethyl, difluoromethyl,
trifluoromethyl, 1,1,1-trifluoroethyl, and the like. Illustrating
further, "haloalkoxy" means an alkoxy wherein at least one hydrogen
radical is replaced by a halogen radical. Examples of haloalkoxy
substituents include chloromethoxy, 1-bromoethoxy, fluoromethoxy,
difluoromethoxy, trifluoromethoxy (also known as
"perfluoromethyoxy"), 1,1,1,-trifluoroethoxy, and the like. It
should be recognized that if a substituent is substituted by more
than one halogen radical, those halogen radicals may be identical
or different (unless stated otherwise).
[0940] The prefix "perhalo" indicates that every hydrogen radical
on the substituent to which the prefix is attached is replaced with
independently selected halogen radicals, i.e., each hydrogen
radical on the substituent is replaced with a halogen radical. If
all the halogen radicals are identical, the prefix typically will
identify the halogen radical. Thus, for example, the term
"perfluoro" means that every hydrogen radical on the substituent to
which the prefix is attached is substituted with a fluorine
radical. To illustrate, the term "perfluoroalkyl" means an alkyl
wherein a fluorine radical is in the place of each hydrogen
radical. Examples of perfluoroalkyl substituents include
trifluoromethyl (--CF.sub.3), perfluorobutyl, perfluoroisopropyl,
perfluorododecyl, perfluorodecyl, and the like. To illustrate
further, the term "perfluoroalkoxy" means an alkoxy wherein each
hydrogen radical is replaced with a fluorine radical. Examples of
perfluoroalkoxy substituents include trifluoromethoxy
(--O--CF.sub.3), perfluorobutoxy, perfluoroisopropoxy,

--C(S)-alkyl-heterocyclyl.

example, "phenyloxy(thiocarbonyl)" may be depicted as: 228
[0965] The term "carbocyclylalkoxy(thiocarbonyl)" (alone or in
combination with another term(s)) means
--C(S)--O-alkyl-carbocyclyl. For example,
"phenylethoxy(thiocarbonyl)" may be depicted as: 229
[0966] The term "sulfonyl" (alone or in combination with another
term(s)) means --S(O).sub.2--, which also may be depicted as:
230
[0967] Thus, for example, "alkyl-sulfonyl-alkyl" means
alkyl--S(O).sub.2-alkyl.
[0968] The term "aminosulfonyl" (alone or in combination with
another term(s)) means --S(O).sub.2--NH.sub.2, which also may be
depicted as: 231
[0969] The term "sulfoxido" (alone or in combination with another
term(s)) means --S(O)--, which also may be depicted as: 232
[0970] Thus, for example, "alkyl-sulfoxido-alkyl" means
alkyl--S(O)-alkyl.
[0971] The term "heterocyclyl" (alone or in combination with
another term(s)) means a saturated (i.e., "heterocycloalkyl"),
partially saturated, or aryl (i.e., "heteroaryl") ring structure
containing a total of 3 to 14 ring atoms. At least one of the ring
atoms is a heteroatom (i.e., oxygen, nitrogen, or sulfur), with the

[0976] A carbocyclyl or heterocyclyl can optionally be substituted

heteroarylcarbonyl, heteroaryl-C.sub.1-C.sub.6-a- lkylcarbonyl,
heteroaryloxycarbonyl, heteroarylcarbonyloxy, and
heteroaryl-C.sub.1-C.sub.6-alkoxycarbonyl. Here, one or more
hydrogen bound to a carbon in any such substituent may, for
example, optionally be replaced with halogen. In addition, the
cycloalkyl, aryl, and heteroaryl are typically single-ring
substituents containing 3 to 6 ring atoms, and more typically 5 or
6 ring atoms.
[0978] A prefix attached to a multi-component substituent only
applies to the first component. To illustrate, the term
"alkylcycloalkyl" contains two components: alkyl and cycloalkyl.
Thus, the C.sub.1-C.sub.6- prefix on
C.sub.1-C.sub.6-alkylcycloalkyl means that the alkyl component of
the alkylcycloalkyl contains from 1 to 6 carbon atoms; the
C.sub.1-C.sub.6- prefix does not describe the cycloalkyl component.
To illustrate further, the prefix "halo" on haloalkoxyalkyl
indicates that only the alkoxy component of the alkoxyalkyl
substituent is substituted with one or more halogen radicals. If
halogen substitution may alternatively or additionally occur on the
alkyl component, the substituent would instead be described as
"halogen-substituted alkoxyalkyl" rather than "haloalkoxyalkyl."
And finally, if the halogen substitution may only occur on the
alkyl component, the substituent would instead be described as
"alkoxyhaloalkyl."
[0979] If substituents are described as being "independently
selected" from a group, each substituent is selected independent of
the other. Each substituent therefore may be identical to or
different from the other substituent(s).
[0980] When words are used to describe a substituent, the
rightmost-described component of the substituent is the component
that has the free valence. To illustrate, benzene substituted with
methoxyethyl has the following structure: 233
[0981] As can be seen, the ethyl is bound to the benzene, and the
methoxy is the component of the substituent that is the component
furthest from the benzene. As further illustration, benzene
substituted with cyclohexanylthiobutoxy has the following
structure: 234
[0982] When words are used to describe a linking element between
two other elements of a depicted chemical structure, the
rightmost-described component of the substituent is the component
that is bound to the left element in the depicted structure. To
illustrate, if the chemical structure is X-L-Y and L is described
as methylcyclohexanylethyl, then the chemical would be
X-ethyl-cyclohexanyl-methyl-Y.
[0983] When a chemical formula is used to describe a substituent,
the dash on the left side of the formula indicates the portion of
the substituent that has the free valence. To illustrate, benzene
substituted with --C(O)--OH has the following structure: 235
[0984] When a chemical formula is used to describe a linking
element between two other elements of a depicted chemical
structure, the leftmost dash of the substituent indicates the
portion of the substituent that is bound to the left element in the
depicted structure. The rightmost dash, on the other hand,
indicates the portion of the substituent that is bound to the right
element in the depicted structure. To illustrate, if the depicted
chemical structure is X-L-Y and L is described as --C(O)--N(H)--,
then the chemical would be: 236
[0985] The term "pharmaceutically acceptable" is used adjectivally
in this patent to mean that the modified noun is appropriate for
use as a pharmaceutical product or as a part of a pharmaceutical
product.
[0986] With reference to the use of the words "comprise" or
"comprises" or "comprising" in this patent (including the claims),
Applicants note that unless the context requires otherwise, those
words are used on the basis and clear understanding that they are
to be interpreted inclusively, rather than exclusively, and that
Applicants intend each of those words to be so interpreted in
construing this patent, including the claims below.

added water (700 ml), followed by Oxone.TM. (600 g, 0.98 mol). The
reaction mixture was stirred overnight. Once HPLC showed
completion, the reaction mixture was filtered to remove excess
Oxone.TM., and the mother liquor was then extracted with ethyl
acetate (3.times.). The combined organic layers were washed with
water (2.times.), dried over magnesium sulfate, filtered, and
concentrated in vacuo to afford 78.3 g (64% crude yield) of a
yellow oil. Both .sup.19F and .sup.1H NMR were consistent with the
desired sulfone with no starting material remaining. This material
was used without further purification.
[0992] Part C. To a solution of the product from Part B (78 g, 0.28
mol) in N,N-dimethylacetamide (300 ml) was added potassium
carbonate (86 g, 0.62 mol). After stirring for 5 min,

concentrated in vacuo. The resulting solid was triturated with
diethyl ether, and 15.3 g (53%) of the pure desired product was
collected as a white powder. ESMS m/z=522 [M+Na].sup.+. The
filtrate contained 11.6 g of material which was shown by HPLC to be
55% product. This material could be purified by flash
chromatography to obtain more material if desired.
[0994] Part E. The product from Part D (15.3 g, 30.6 mmol) was
taken up in 4N HCl in dioxane (17 mL). After 1 hr, HPLC indicated
incomplete reaction, so additional 4N HCl in dioxane (2 mL) was
added. After 20 min, the reaction mixture was slowly added to
rapidly stirring diethyl ether (400 mL). The resulting oily solid
was rinsed with more diethyl ether then dissolved in acetonitrile
and concentrated in vacuo. 12.3 g (92%) of the desired
hydrochloride salt was obtained as a white solid. ESMS m/z=400

In Vitro MMP Inhibition Analysis
[1307] Several hydroxamates and salts thereof were analyzed in in
vitro assays to determine their ability to inhibit the MMP cleavage
of peptide substrates. Inhibition (K.sub.i) and IC.sub.50 constants
were calculated from the assayed hydroxamate-MMP interactions.
[1308] Human recombinant MMP-1, MMP-2, MMP-9, MMP-13, and MMP-14
ere used in this assay. All enzymes were prepared in Assignee's
laboratories following usual laboratory procedures. Protocols for
the preparation and use of these enzymes are available in the
scientific literature. See, e.g., Enzyme Nomenclature (Academic
Press, San Diego, Calif., 1992) (and the citations therein). See
also, Frije et al., J Biol. Chem., 26(24), 16766-73 (1994).
[1309] The MMP-1 proenzyme was purified from the spent media of
MMP-1-transfected HT-1080 cells provided by Dr. Harold Welgus of
Washington University (St. Louis, Mo.). The protein was purified on
a zinc chelating column.
[1310] The MMP-2 proenzyme was purified by gelatin Sepharose
chromatography from MMP-2-transfected p2AHT2 cells provided by Dr.
Gregory Goldberg of Washington University (St. Louis, Mo.).
[1311] The MMP-9 proenzyme was purified by gelatin Sepharose
chromatography from spent media of MMP-9-transfected HT1080 cells
provided by Dr. Howard Welgus of Washington University (St. Louis,
Mo.).
[1312] The MMP-13 was obtained as a proenzyme from a full-length
cDNA clone using baculovirus, as described by V. A. Luckow, "Insect
Cell Expression Technology," Protein Engineering: Principles and
Practice, pp. 183-218 (edited by J. L. Cleland et al., Wiley-Liss,
Inc., 1996). The expressed proenzyme was first purified over a
heparin agarose column, and then over a chelating zinc chloride
column. The proenzyme was then activated by APMA for use in the
assay. Further details on baculovirus expression systems may be
found in, for example, Luckow et al., J. Virol., 67, 4566-79
(1993). See also, O'Reilly et al, Baculovirus Expression Vectors: A
Laboratory Manual (W. H. Freeman and Co., New York, N.Y., 1992).
See also, King et al., The Baculovirus Expression System: A
Laboratory Guide (Chapman & Hall, London, England, 1992).
[1313] The MMP-14 full length cDNA was provided by Dr. Gregory
Goldberg of Washington University (St. Louis, Mo.). The catalytic
domain enzyme was expressed in E. coli inclusion bodies,
solubilized in urea, purified on a preparative C-14 reverse phase
HPLC column, and then refolded in the presence of zinc acetate and
purified for use.
[1314] All MMPs were activated using 4-aminophenylmercuric acetate
("APMA", Sigma Chemical, St. Louis, Mo.) or trypsin. MMP-9 also was
activated using human recombinant MMP-3 (purified in Assignee's
laboratory following standard cloning and purification
techniques).
[1315] Two fluorogenic, methoxycoumarin-containing polypeptide
substrates were used in the MMP inhibition assays:
MCA-ProLeuGlyLeuDpaAlaArgNH.sub.2 (I)
MCA-ArgProLeuGlyLeuDpaAlaArgGluArgNH.sub.2 (II)
[1316] Here, "Dpa" is 3-(2,4-dinitrophenyl)-L-2,3-diaminopropionyl
group, and "MCA" is 7-methoxycoumarin-4-yl acetyl. Substrate (I)
was purchased from Baychem (Redwood City, Calif.), and substrate II
was prepared Assignee's laboratory. Substrate I was used in the
IC.sub.50 determination assays, while substrate II was used in the
K.sub.i determination assays. In the absence of MMP inhibitory
activity, either substrate is cleaved at the. Gly-Leu peptide bond.
This cleavage separates the highly fluorogenic peptide from the
2,4-dinitrophenyl quencher, thus resulting in increase of
fluorescent intensity.
[1317] The stock solutions of the assayed hydroxamates (or salts
thereof) were prepared in 1% dimethyl sulfoxide (DMSO). These stock
solutions were diluted in Buffer A (100 mM Tris-HCl, 100 mM NaCl,
10 mM CaCl.sub.2, 0.05% polyoxyethylene 23 lauryl ether, pH 7.5) to
obtain solutions with different hydroxamate concentrations, i.e.,
assay solutions with different concentrations of the assayed MMP
inhibitory compound. The experiment controls contained the same
amount of Buffer A/DMSO as the assayed sample, but contained no
hydroxamate (or salt thereof).
[1318] The assays from which the IC.sub.50 determinations were made
were performed as follows. The MMPs were activated with either
trypsin or APMA (4-aminophenylmercuric acetate, Sigma Chemical, St.
Louis, Mo.). The assayed hydroxamate samples were incubated in
Microfluor.TM. White Plates (Dynatech, Chantilly, Va.) and analyzed
on a Perkin Elmer L550 plate reader (Norwalk, Conn.). The
excitation wavelength was 328 nm, and the emission wavelength -415
nm. All samples (assayed hydroxamates and controls) were incubated
in separate plates at room temperature in the presence of 4 .mu.M
of MMP substrate (I). As stated in the previous paragraph, samples
containing varying concentrations of the same assayed hydroxamate
were prepared. Inhibition was measured as a reduction in
fluorescent intensity as a function of MMP inhibitor
concentration.
[1319] The assays from which the K.sub.i determinations were made
were performed as follows. The assayed hydroxamate samples were
incubated in separate wells of untreated white polystyrene plates
(Nunc Nalgene International, Rochester, N.Y.), and analyzed on a
Tecan SpectraFlour Plus plate reader. The excitation wavelength was
330 nm, and the emission wavelength -420 nm. All samples (assayed
hydroxamates and controls) were incubated in separate plate wells
at room temperature for 1 hr in the presence of 4 .mu.M of MMP
substrate (II). In the absence of MMP inhibitory activity,
substrate II was cleaved at the Gly-Leu bond resulting in an
increase of relative fluorescence. Inhibition was observed as a
reduced rate of this increase in relative fluorescence. The various
hydroxamates were analyzed using a single low enzyme concentration
with a single substrate concentration fixed at or below the
K.sub.m. This protocol is a modification of method by Knight et
al., FEBS Lett., 296(3), 263-266 (1992). Apparent inhibitory
constants were determined by non-linear regression of reaction
velocity as a function of inhibitor and enzyme concentration using
Morrison's equation, as described by Kuzmic, Anal. Biochem. 286,
45-50 (2000). Modifications were made in the non-linear regression
method to allow a common control reaction rate and effective enzyme
concentration to be shared between all dose-response relationships
on a given assay plate. Since the substrate concentration was
chosen to be at or below the K.sub.m, the apparent K.sub.i's from
this analysis were reported as K.sub.i's without correction for the
influence of substrate.
[1320] The above protocols were used to determine IC50 constants
and K.sub.i values values for several of the compounds in Examples
1-52 above. The results are shown in Table 5. All values in Table 5
are given in nM units. The K.sub.i measurements are in
parenthesis.

In Vivo Angiogenesis Assay
[1321] The study of angiogenesis depends on a reliable and
reproducible model for the stimulation and inhibition of a
neovascular response. The corneal micropocket assay provides such a
model of angiogenesis in the cornea of a mouse. See, A Model of
Angiogenesis in the Mouse Cornea; Kenyon, B M, et al.,
Investigative Ophthalmology & Visual Science, July 1996, Vol.
37, No. 8.
[1322] In this assay, uniformLy sized Hydron.TM. pellets containing
bFGF and sucralfate are prepared and surgically implanted into the
stroma mouse cornea adjacent to the temporal limbus. The pellets
are formed by making a suspension of 20 .mu.L sterile saline
containing 10 .mu.g recombinant bFGF, 10 mg of sucralfate and 10
.mu.L of 12 percent Hydron.TM. in ethanol. The slurry is then
deposited on a 10.times.10 mm piece of sterile nylon mesh. After
drying, the nylon fibers of the mesh are separated to release the
pellets.
[1323] The corneal pocket is made by anesthetizing a 7 week old
C57B1/6 female mouse, then proptosing the eye with a jeweler's
forceps. Using a dissecting microscope, a central, intrastromal
linear keratotomy of approximately 0.6 mm in length is performed
with a #15 surgical blade, parallel to the insertion of the lateral
rectus muscle. Using a modified cataract knife, a lamellar
micropocket is dissected toward the temporal limbus. The pocket is
extended to within 1.0 mm of the temporal limbus. A single pellet
is placed on the corneal surface at the base of the pocket with a
jeweler's forceps. The pellet is then advanced to the temporal end
of the pocket. Antibiotic ointment is then applied to the eye.
[1324] Mice are dosed on a daily basis for the duration of the
assay. Dosing of the animals is based on bioavailability and
overall potency of the compound. An exemplary dose is 10 or 50
mg/kg (mpk) bid, po. Neovascularization of the corneal stroma is
permitted to continue under the influence of the assayed compound
for 2 days. At that point, the degree of angiogenic inhibition is
scored by viewing the neovascular progression with a slit lamp
microscope.
[1325] The mice are anesthetized and the studied eye is once again
proptosed. The maximum vessel length of neovascularization,
extending from the limbal vascular plexus toward the pellet is
measured. In addition, the contiguous circumferential zone of
neovascularization is measured as clock hours, where 30 degrees of
arc equals one clock hour. The area of angiogenesis is calculated
as follows. 1 area = ( 0.4 .times. clock hours .times. 3.14 .times.
vessel length ( in mm ) ) 2
[1326] Five to six mice should be utilized for each compound in
each study. The studied mice are thereafter compared to control
mice and the difference in the area of neovascularization is
recorded as an averaged value. Each group of mice so studied
constitutes an "n" value of one, so that "n" values greater than
one represent multiple studies whose averaged result is provided in
the table. A contemplated compound typically exhibits about 25 to
about 75 percent inhibition, whereas the vehicle control exhibits
zero percent inhibition.

Tumor Necrosis Factor Assays
[1327] Cell Culture.
[1328] The cells used in the assay are the human moncytic line
U-937 (ATCC CRL-1593). The cells are grown in RPMI w/10% FCS and
PSG supplement (R-10) and are not permitted to overgrow. The assay
is carried out as follows:
[1329] 1. Count, then harvest cells by centrifugation. Resuspend
the pellet in R-10 supplement to a concentration of
1.540.times.10.sup.6 cells/mL.
[1330] 2. Add test compound in 65 uL R-10 to the appropriate wells
of a 96-well flat bottom tissue culture plate. The initial dilution
from a DMSO stock (100 mM compound) provides a 400 uM solution,
from which five additional three-fold serial dilutions are made.
Each dilution of 65 ul (in triplicate) yields final compound test
concentrations of 100 .mu.M, 33.3 .mu.M, 11.1 .mu.M, 3.7 .mu.M, 1.2
.mu.M and 0.4 .mu.M.
[1331] 3. The counted, washed and resuspended cells (200,000

In Vitro Aggrecanase Inhibition Analysis
[1373] Assays for measuring the potency (IC.sub.50) of a compound
toward inhibiting aggrecanase are known in the art.
[1374] One such assay, for example, is reported in European Patent
Application Publ. No. EP 1 081 137 A1. In that assay, primary
porcine chondrocytes from articular joint cartilage are isolated by
sequential trypsin and collagenase digestion followed by
collagenase digestion overnight and are plated at 2.times.10.sup.5
cells per well into 48 well plates with 5 .mu.Ci/ml.sup.35S (1000
Ci/mmol) sulphur in type 1 collagen coated plates. Cells are
allowed to incorporate label into their proteoglycan matrix
(approximately 1 week) at 37.degree. C. under an atmosphere of 5%
CO.sub.2. The night before initiating the assay, chondrocyte
monolayers are washed 2 times in DMEM/1% PSF/G and then allowed to
incubate in fresh DMEM/1% FBS overnight. The next morning,
chondrocytes are washed once in DMEM/1% PSF/G. The final wash is
allowed to sit on the plates in the incubator while making
dilutions. Media and dilutions are made as described in the
following Table 6:
6TABLE 6 control media DMEM alone IL-1 media DMEM + IL-1 (5 ng/ml)
drug dilutions Make all compound stocks at 10 mM in DMSO. Make a
100 .mu.M stock of each compound in DMEM in 96-well plate. Store in
freezer overnight. The next day, perform serial dilutions in DMEM
with IL-1 to 5 .mu.M, 500 nM, and 50 nM. Aspirate final wash from
wells and add 50 .mu.M of compound from above dilutions to 450
.mu.L of IL-1 media in appropriate wells of the 48 well plates.
Final compound concentrations equal 500 nM, 50 nM, and 5 nM. All
samples completed in triplicate with control and IL-1 alone on each
plate.
[1375] Plates are labeled and only the interior 24 wells of the
plate are used. On one of the plates, several columns are
designated as IL-1 (no drug) and control (no IL-1, no drug). These
control columns are periodically counted to monitor
35S-proteoglycan release. Control and IL-1 media are added to wells
(450 .mu.L) followed by compound (50 .mu.L) so as to initiate the
assay. Plates are incubated at 37.degree. C. with 5% CO.sub.2
atmosphere. At 40-50% release (when CPM from IL-1 media is 4-5
times control media) as assessed by liquid scintillation counting
(LSC) of media samples, the assay is terminated (about 9 to about
12 hours). Media is removed from all wells and placed into
scintillation tubes. Scintillate is added and radioactive counts
are acquired (LSC). To solubilize cell layers, 500 .mu.L of papain
digestion buffer (0.2 M Tris, pH 7.0, 5 mM DTT, and 1 mg/ml papain)
is added to each well. Plates with digestion solution are incubated
at 60.degree. C. overnight. The cell layer is removed from the
plates the next day and placed in scintillation tubes. Scintillate
is then added, and samples counted (LSC). The percent of released
counts from the total present in each well is determined. Averages
of the triplicates are made with control background subtracted from
each well. The percent of compound inhibition is based on IL-1
samples as 0% inhibition (100% of total counts).
[1376] Another assay for measuring aggrecanase inhibition is
reported in WIPO Int'l Publ. No. WO 00/59874. That assay reportedly
uses active aggrecanase accumulated in media from stimulated bovine
cartilage (BNC) or related cartilage sources and purified cartilage
aggrecan monomer or a fragment thereof as a substrate. Aggrecanase
is generated by stimulation of cartilage slices with interleukin-1
(IL-1), tumor necrosis factor alpha (TNF-.alpha.), or other
stimuli. To accumulate BNC aggrecanase in culture media, cartilage
reportedly is first depleted of endogenous aggrecan by stimulation
with 500 ng/ml human recombinant IL-.beta. for 6 days with media
changes every 2 days. Cartilage is then stimulated for an
additional 8 days without media change to allow accumulation of
soluble, active aggrecanase in the culture media. To decrease the
amounts of matrix metalloproteinases released into the media during
aggrecanase accumulation, agents which inhibit MMP-1, -2,-3, and -9
biosynthesis are included during stimulation. This BNC conditioned
media containing aggrecanase activity is then used as the source of
aggrecanase for the assay. Aggrecanase enzymatic activity is
detected by monitoring production of aggrecan fragments produced
exclusively by cleavage at the Glu373-Ala374 bond within the
aggrecan core protein by Western analysis using the monoclonal
antibody, BC-3 (Hughes, et al., Biochem J, 306:799-804 (1995)).
This antibody reportedly recognizes aggrecan fragments with the
N-terminus, 374ARGSVIL, generated upon cleavage by aggrecanase. The
BC-3 antibody reportedly recognizes this neoepitope only when it is
at the N-terminus and not when it is present internally within
aggrecan fragments or within the aggrecan protein core. Only
products produced upon cleavage by aggrecanase reportedly are
detected. Kinetic studies using this assay reportedly yield a Km of
1.5.+-.0.35 .mu.M for aggrecanase. To evaluate inhibition of
aggrecanase, compounds are prepared as 10 mM stocks in DMSO, water,
or other solvents and diluted to appropriate concentrations in
water. Drug (50 .mu.L) is added to 50 .mu.L of
aggrecanase-containing media and 50 .mu.L of 2 mg/ml aggrecan
substrate and brought to a final volume of 200 .mu.L in 0.2 M Tris,
pH 7.6, containing 0.4 M NaCl and 40 mM CaCl.sub.2. The assay is
run for 4 hr at 37.degree. C., quenched with 20 mM EDTA, and
analyzed for aggrecanase-generated products. A sample containing
enzyme and substrate without drug is included as a positive control
and enzyme incubated in the absence of substrate serves as a
measure of background. Removal of the glycosaminoglycan side chains
from aggrecan reportedly is necessary for the BC-3 antibody to
recognize the ARGSVIL epitope on the core protein. Therefore, for
analysis of aggrecan fragments generated by cleavage at the
Glu373-Ala374 site, proteoglycans and proteoglycan fragments are
enzymatically deglycosylated with chondroitinase ABC (0.1 units/10
.mu.g GAG) for 2 hr at 37.degree. C. and then with keratanase (0.1
units/10 .mu.g GAG) and keratanase II (0.002 units/10 .mu.g GAG)
for 2 hr at 37.degree. C. in buffer containing 50 mM sodium
acetate, 0.1 M Tris/HCl, pH 6.5. After digestion, aggrecan in the
samples is precipitated with 5 volumes of acetone and resuspended
in 30 .mu.L of Tris glycine SDS sample buffer (Novex) containing
2.5% beta mercaptoethanol. Samples are loaded and then separated by
SDS-PAGE under reducing conditions with 4-12% gradient gels,
transferred to nitrocellulose and immunolocated with 1:500 dilution
of antibody BC3. Subsequently, membranes are incubated with a
1:5000 dilution of goat anti-mouse IgG alkaline phosphatase second
antibody and aggrecan catabolites visualized by incubation with
appropriate substrate for 10-30 minutes to achieve optimal color
development. Blots are quantitated by scanning densitometry and
inhibition of aggrecanase determined by comparing the amount of
product produced in the presence versus absence of compound.

prepared by one skilled in the art using methods similar to those
described in Examples 1-54 alone or in combination with techniques
well known in the art. Such compounds include, for example, the
compounds summarized in the following Table 7. Table 7 also
summarizes in vitro MMP inhibition results obtained by Applicants
with the listed hydroxamates. As with Table 5, all in vitro K.sub.i
and IC.sub.50 results in Table 7 are given in nM units. The Ki
