Description
[0001] This application claims the priority benefit under 35 U.S.C.
.sctn. 119 of U.S. Provisional Appl. No. 60/194,505, filed Apr. 3,
2000, the entirety of which is incorporated by reference
herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention is in the field of inhibitors of
plasminogen activator inhibitor-1 (PAI-1) activity. More
particularly, the invention relates to the use of substituted
thiazoles as inhibitors of PAI-1, and to novel classes of
2-substituted thiazole derivatives, their synthesis and their use
as inhibitors of PAI-1.
[0004] 2. Related Art
[0005] PAI-1 is a naturally occurring serine protease inhibitor, or
serpin, that rapidly inhibits the activity of several proteases,
including tissue plasminogen activator (tPA) and urokinase
plasminogen activator (uPA), by forming equimolar, irreversible
complexes that are internalized and degraded. In this capacity,
PAI-1 plays a major role in preventing fibrinolysis by decreasing
the level of tPA and/or uPA, and consequently, the level of
plasminogen converted to plasmin. Plasmin is an enzyme critical to
the lysis of fibrin clots and works by cleaving fibrin to small
soluble products.
[0006] PAI-1 can contribute to a variety of coronary diseases by
retarding the clearance of thrombi. Elevated levels of PAI-1 have
been described to correlate with an increased risk of
atherosclerosis (Lupu, F., et al., Arteriosclerosis and Thrombosis
13:1090-1100 (1993)), deep vein thrombosis (Patrassi, G. M., et al.
Fibrinolysis 6:99-102 (1992)) and of thrombosis during sepsis,
surgery and trauma (Kluft, C., et al., Scand. J. Clin. Lab. Invest.
45:605-610 (1985)). Elevated PAI-1 levels are also thought to
contribute to the high incidence of coronary disease in individuals
with Type 2 diabetes (Sobel, B. E., el al., Circulation
97(22):22113-2221(1998)), obese individuals (Lundgren, C. H., et
al., Circulation 93(1):106-110 (1996)), and the elderly (Lupu, F.,
et al., Arteriosclerosis and Thrombosis 13:1090-1100 (1993)).
[0007] Increased PAI-1 has been demonstrated in human
atherosclerotic vessel walls and may contribute to the impaired
plasma fibrinolytic capacity in patients at high risk of
atherothrombotic events. The atherosclerotic process begins with an
injury to the inner lining of the blood vessel, the endothelium.
Smooth muscle cells migrate from their normal location in the media
to the intima, where they divide and make up a bulk lesion.
[0008] Immunohistochemical analyses have revealed that most of the
PAI-1 in the thickened intima of early lesions is located in and
around neointimal smooth muscle cells and possibly macrophages.
Both of these cell types can become lipid-laden foam cells that
form fatty streaks, another hallmark feature of
atherosclerosis.
[0009] In advanced lesions, larger amounts of PAI-1 are expressed
by smooth muscle cells and macrophages in the necrotic core. Most
of the PAI-1 of this advanced stage is in complex tPA, suggesting
that PAI-1 has an important function in modulating mural tPA
activity (Padro, T., et al., Arterioscler. Thromb. Vasc. Biol.
15:893-902 (1995) and Saweh, H., et al., Circ. Res. 73:671-680
(1993)). These findings have been supported with experimental work
in rabbits that demonstrated an increase in PAI-1 expression in
activated endothelial cells, macrophages and smooth muscle cells in
response to sustained mechanical injury. The increase in PAI-1
transcription paralleled the severity of vascular lesions induced
and was increased in hypercholesterolemic rabbits (Kruithof, E. K.
O. et al., Blood 70:1645-1653 (1987)). These results suggest that
enhanced PAI-1 expression is a feature of early atherosclerosis and
that a PAI-1 inhibitor may be effective preventive therapeutics for
high risk patients.
[0010] A PAI-1 inhibitor may also serve as an anticancer agent. An
antibody to PAI-1 has been shown to suppress metastasis in several
cancer models (Tsuchiya, H., et al., Gen. Diag., Pathol. 141:41-48
(1995)). In cultured lung cancer cells, PAI-1 is necessary for
optimum invasion (Liu, G., el al., Int. J. Cancer 60:501-506
(1995)). Further, cancer invasion and tumor vascularization have
been prevented in PAI-1 knockout mice implanted with malignant
murine keratinocytes (Bajou, K., et al., Nature Med. 4(8):923-928
(1998)). This indicates that PAI-1 plays an integral role in tumor
progression.
[0011] PAI-1 is also expressed at high levels by smooth muscle and
endothelial cells, and it regulates the proteolytic activity
surrounding the formation of blood vessels. A PAI-1 inhibitor may
be suitable as an anti-angiogenic agent by hindering proper vessel
formation around tumor. In fact, transduced endothelial cells that
express decreased PAI-1 activity compared with normal endothelial
cells were found to form large ectactic sac-like structures
resembling haemangiomas when cultured in fibrin gels, suggesting
abnormal vessel formation (Lawrence, D. A., et al., J. Biol. Chem.
269(21): 15223-15229 (1994)).

Formula: 2
[0013] wherein n is 3 or 4. These compounds are disclosed to be

[0158] PAI-1 Assay
[0159] The inhibitory activity of PAI-1 against uPA was measured by
a direct chromogenic assay using the substrate N-CB-VAL-GLY-ARG
p-nitroanilide. The tested compound was added to PAI-1 which had
been diluted in activity assay buffer (0.05M Hepes, pH 7.5, 0.1 5M
NaCl, containing 0.05% N-octyl-D-glucopyranoside and 250 .mu.g/ml
bovine serum albumin). After a 10 minute incubation at 37.degree.
C., uPA was added (0.04 units/assay), followed immediately by the
addition of substrate. After reequilibration at 37.degree. C.,
residual uPA activity was quantified by measuring the change in
absorbance at 405 nm over 12 minutes. The concentration of active
PAI-1 in the assays was the amount required to inhibit 80-85% of
uPA as compared to samples containing uPA alone.
[0160] Compositions within the scope of the invention include all
compositions wherein the compounds of the present invention are
contained in an amount that is effective to achieve its intended
purpose. While individual needs vary, determination of optimal
ranges of effective amounts of each component is within the skill
of the art. Typically, the compounds may be administered to
mammals, e.g., humans, orally at a dose of 1 to 1000 mg/kg, or an
equivalent amount of the pharmaceutically acceptable salt thereof,
per day of the body weight of the mammal being treated for
thrombosis, angina pectoris, cerebral infarction, myocardial
infarction, pulmonary infarction, intra-atrial thrombus in atrial
fibrillation, deep venous thrombus, disseminated intravascular
coagulation syndrome, diabetic complications, restenosis after
percutaneous transluminal coronary angioplasty and stroke. For
intramuscular injection, the dose is generally about one-half of
the oral dose.
[0161] The unit oral dose may comprise from about 1 to about 1000
mg, preferably about 1 to about 100 mg of the compound. The unit
dose may be administered one or more times daily as one or more
tablets each containing from about 0.1 to about 50, conveniently
about 0.25 to about 100 mg of the compound or its solvates.
[0162] In addition to administering the compound as a raw chemical,
the compounds of the invention may be administered as part of a
pharmaceutical preparation containing suitable pharmaceutically
acceptable carriers comprising excipients and auxiliaries which
facilitate processing of the compounds into preparations which can
be used pharmaceutically. Preferably, the preparations,
particularly those preparations which can be administered orally
and which can be used for the preferred type of administration,
such as tablets, dragees, and capsules, and also preparations which
can be administered rectally, such as suppositories, as well as
suitable solutions for administration by injection or orally,
containing from about 0.01 to 99 percent, preferably from about
0.25 to about 75 percent of active compound(s), together with the
excipient.
[0163] The pharmaceutical compositions of the invention may be
administered to any animal that may experience the beneficial
effects of the compounds of the invention. Foremost among such
animals are mammals, e.g. humans, although the invention is not
intended to be so limited.
[0164] The pharmaceutical compositions of the invention may be
administered by any means that achieve their intended purpose. For
example, administration may be parenteral, subcutaneous,
intravenous, intramuscular, intraperitoneal, transdermal, or buccal
routes. Alternatively, or concurrently, administration may be by
the oral route. The dosage administered will be dependent upon the
age, health, and weight of the recipient, kind of concurrent
treatment, if any, frequency of treatment, and the nature of the
desired effect.
[0165] The pharmaceutical preparations of the present invention are
manufactured in a manner which is itself known, for example, by
means of conventional mixing, granulating, dragee-making,
dissolving, or lyophilizing processes. Thus, pharmaceutical
preparations for oral use can be obtained by combining the active
compounds with solid excipients, optionally grinding the resulting
mixture and processing the mixture of granules, after adding
suitable auxiliaries, if desired or necessary, to obtain tablets or
dragee cores.
[0166] Suitable excipients are, in particular, fillers, such as
saccharides, for example, lactose or sucrose, mannitol or sorbitol,
cellulose preparations and/or calcium phosphates, for example
tricalcium phosphate or calcium hydrogen phosphate, as well as
binders such as starch paste, using, for example, maize starch,
wheat starch, rice starch, potato starch, gelatin, tragacanth,
methyl cellulose, hydroxypropylmethylcellulose, sodium
carboxymethylcellulose, and/or polyvinyl pyrrolidone. If desired,
disintegrating agents may be added such as the above-mentioned
starches and also carboxymethyl-starch, cross-linked polyvinyl
pyrrolidone, agar, or alginic acid or a salt thereof, such as
sodium alginate. Auxiliaries are, above all, flow-regulating agents
and lubricants, for example, silica, talc, stearic acid or salts
thereof, such as magnesium stearate or calcium stearate, and/or
polyethylene glycol. Dragee cores are provided with suitable
coatings which, if desired, are resistant to gastric juices. For
this purpose, concentrated saccharine solutions may be used, which
may optionally contain gum arabic, talc, polyvinyl pyrrolidone,
polyethylene glycol and/or titanium dioxide, lacquer solutions and
suitable organic solvents or solvent mixtures. In order to produce
coatings resistant to gastric juices, solutions of suitable
cellulose preparations, such as acetylcellulose phthalate or
hydroxypropylmethylcellulose phthalate, are used. Dye stuffs or
pigments may be added to the tablets or dragee coatings, for
example, for identification or in order to characterize
combinations of active compound doses.
[0167] Other pharmaceutical preparations which can be used orally
include push-fit capsules made of gelatin, as well as soft, sealed
capsules made of gelatin and a plasticizer such as glycerol or
sorbitol. The push-fit capsules can contain the active compounds in
the form of granules which may be mixed with fillers such as
lactose, binders such as starches, and/or lubricants such as talc
or magnesium stearate and, optionally, stabilizers. In soft
capsules, the active compounds are preferably dissolved or
suspended in suitable liquids, such as fatty oils, or liquid
paraffin. In addition, stabilizers may be added.
[0168] Possible pharmaceutical preparations, which can be used
rectally, include, for example, suppositories, which consist of a
combination of one or more of the active compounds with a
suppository base. Suitable suppository bases are, for example,
natural or synthetic triglycerides, or paraffin hydrocarbons. In
addition, it is also possible to use gelatin rectal capsules which
consist of a combination of the active compounds with a base.
Possible base materials include, for example, liquid triglycerides,
polyethylene glycols, or paraffin hydrocarbons.
[0169] Suitable formulations for parenteral administration include
aqueous solutions of the active compounds in water-soluble form,
for example, water soluble salts and alkaline solutions. In
addition, suspensions of the active compounds as appropriate oily
injection suspensions may be administered. Suitable lipophilic
solvents or vehicles include fatty oils, for example, sesame oil,
or synthetic fatty acid esters, for example, ethyl oleate or
triglycerides or polyethylene glycol-400 (the compounds are soluble
in PEG-400). Aqueous injection suspensions may contain substances
which increase the viscosity of the suspension, and include, for
example, sodium carboxymethyl cellulose, sorbitol, and/or dextran.
Optionally, the suspension may also contain stabilizers.
