## Background
RELATED APPLICATIONS
This application claims priority benefit under Title 35 § 119(e) of U.S. Provisional Application No. 60/499,498, filed Sep. 2, 2003, the contents of which are herein incorporated by reference.


FIELD OF THE INVENTION
The present invention relates to pyrazolyl inhibitors of the enzyme 15-lipoxygenase (“15-LO”), pharmaceutical compositions comprising said inhibitors, and methods of treating diseases responsive to inhibition of 15-lipoxygenase.
BACKGROUND OF THE INVENTION
The 15-LO cascade is implicated in various inflammatory disorders, including disorders involving the origin and recruitment of foam cells. Cholesterol is transported in blood particles called lipoproteins, which include low-density lipoproteins (LDL). Lipoproteins contain cholesterol and are necessary for foam cell formation. The formation of foam cells can lead to serious disorders. For example, hypercholesterolemia can induce monocytes to migrate into the arterial wall and mature into foam cells or tissue macrophages that accumulate fatty material, including cholesterol esters. Continued creation of foam cells thickens the inner lining of medium and large arteries, thereby forming atherosclerotic plaques or lesions containing cholesterol, smooth muscle cells, and connective tissue cells. Affected arteries lose elasticity and become narrowed or obstructed by the plaques indicating the onset of atherosclerosis. Atherosclerotic plaques may collect calcium, become brittle, and even rupture triggering the formation of a blood clot or thrombus capable of occluding an artery and causing a stroke or heart attack. In addition to atherosclerosis, hypercholesteremia plays a role in peripheral vascular diseases of small arteries, veins and lymphatics. Thus, hypercholesteremia may also affect the arms, legs, kidneys and other vital organs in addition to the heart and brain.
Lipoxygenases are enzymes that catalyze the oxidation of polyunsaturated fatty acids and esters thereof, including those found in low-density lipoproteins. In addition to metabolism of free fatty acids, the enzyme 15-lipoxygenase (15-LO) also oxidizes esterified polyenoic fatty acids. Related to its general pathology, it is believed that oxidative metabolites of the 15-LO cascade [e.g. the arachidonic acid metabolite 15-hydroperoxyeicosatetraenoic acid (15-HPETE)], induce endothelial cell activation and subsequent adhesion molecule expression resulting in monocyte recruitment to the vessel wall [Sultana et al, J. of Cellular Physiology 167 (1996) 467-487]. 15-Hydroxyeicosatetraenoic acid (15-HETE), a reduction product of 15-HPETE, has also been implicated in the potentiation of thrombin-induced platelet activation [Setty et al, Blood, 80:11 (1992): 2765-2773]. It has also been demonstrated that arachidonic acid metabolites of the 15-LO cascade, namely 15-hydroperoxyeicosatetraenoic acid (15-HPETE), induce a pro-thrombotic state in endothelial cells through enhancement of plasminogen activator inhibitor-1 (PAI-1) release. Additionally, evidence that 15-LO is involved in the pathology of diabetes, it has been demonstrated that deletion of the mouse gene homologue of 15-LO leads to a reduction of disease progression [Bleich et al, J Clin Invest (1999) May 15;103(10):1431-6]. 15-LO has also been implicated in the progression of various cancers [Kelavkar et al, Curr Urol Rep June 2002; 3(3):207-14]. Not only in the progression of the cancer itself, but also in its related pathologies including cachexia and wasting [Tisdale et al, Science 2000 Sep. 29;289(5488):2293-4].
Inhibition of 15-LO, therefore, would be useful to prevent and treat diseases with either an inflammatory component, a thrombotic component, or both as in the case of atherosclerosis, as well as various cancers. For example, it has been shown that treatment with a 15-LO inhibitor suppressed atherogenesis (or the production of atheroma—a fatty degeneration of the arterial wall) in rabbits fed a high-fat diet [Bocan et al, Atherosclerosis, 136 (1998): 203-216]. Additional diseases in which treatment with a 15-LO inhibitor would be useful include asthma, psoriasis, osteoarthritis, rheumatoid arthritis, Alzheimer's disease, and chronic obstructive pulmonary disease.

Prodrugs and solvates of the compounds of the invention are also contemplated herein. The term “prodrug”, as employed herein, denotes a compound which, upon administration to a subject, undergoes chemical conversion by metabolic or chemical processes to yield a compound of the formula I, or a salt and/or solvate thereof. Solvates of the compounds of formula I are preferably hydrates. Any tautomers which may exist are also contemplated herein as part of the present invention.
All stereoisomers of the present compounds, such as those which may exist due to asymmetric carbons on the R substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons, e.g., atropisomers) and diastereomeric forms, are contemplated within the scope of this invention. Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations.
Methods of Preparation
The compounds of the present invention may be prepared by methods such as those illustrated in Scheme 1. Solvents, temperatures, pressures, and other reaction conditions may be selected by one of ordinary skill in the art. Starting materials are commercially available or readily prepared by one of ordinary skill in the art.
Scheme 1 illustrates the synthesis of pyrazoles via intermediate 1,3-dicarbonyl compounds. Gamma-chloro ketones II not available from commercial vendors may be prepared by the method of Sato et al. (Chem. Pharm. Bull., 1978, 3296-3305). Alternatively, gamma-chloro aryl propyl ketones may be prepared from Weinreb amide I (Shimizu et al. Tetrahedron Letters.; EN; 38; 15; 1997; 2685-2688) by treatment with an organometallic nucleophile (organolithium, Grignard reagentor the like) at low temperature (typically −78° C.) to give an intermediate chloroketone II. The chloride may then be displaced by azide anion (sodium azide or a related salt) between 0-100° C. (typically 70° C.) to give the azide product III (X═N3). Alternatively, the phthalimide product III (X═NPhth) may be prepared from chloroketone II by displacement of chloride with phthalimide anion (typically potassium phthalimide). Treament of ketone III with a suitable base (e.g., lithium bis(trimethylsilyl)amide or lithium diisopropylamide) at low temperature (typically −78° C.) will provide an enolate intermediate which may then react with a suitably activated carboxylic acid derivative (acid chloride, Weinreb amide, N-hydroxy succinimide ester or the like) to provide a 1,3-dicarbonyl intermediate IV. Condensation of the 1,3-dicarbonyl compound IV with a hydrazine gives a pyrazole product which may be formed either as isomer Va, Vb, or a mixture of both. Isomers Va and Vb may typically be separated by flash column chromatography or preparative HPLC. Reduction of Va or Vb when X=azide (N3) to provide amine VIa or VIb may be carried out under heterogeneous catalytic hydrogenation conditions, typically using palladium on carbon (10% w/w) and hydrogen gas in methanol as solvent. Alternatively, reduction of the azide may be accomplished by Staudinger reduction (triphenylphosphine, water). When X=phthalimide, treatment of Va or Vb with hydrazine in methanol or a mixture of THF and methanol at 0-100° C. (typically 70° C.) provides the amine VIa or VIb.
Further elaboration of the amine to the final compounds may be accomplished using ordinary techniques known to one skilled in the art. Non-symmetrical sulfamides have been prepared via intermediate N-sulfamoyloxazolidinones following the method of Ducry et al. (Helv. Chim. Act. 1992, 82 (12), 2432-2447). Typically, to 1 eq. of chlorosulfonyl isocyanate in dry dichloromethane (0.22 M) at −20° C. is added 2-chloroethanol dropwise. The temperature is allowed to warm to 0° C. and the solution maintained at that temperature for 1.5 h. The solution is then cooled to −20° C. and added via canula to a solution (or suspension) of an amine (1 eq.) and triethylamine (7 eq) in dichloromethane (0.25 M) at 0° C. The reaction mixture is allowed to warm to and maintained at room temperature 16 h. The intermediate sulfamoyloxazolidinone may be purified by preparative HPLC. Alternatively, the reaction mixture may be concentrated in vacuo and used directly in the next step without further purification.
Heating a solution of the intermediate sulfamoyloxazolidinone in dry acetonitrile (0.1-0.5 M) in the presence of excess triethylamine (7-10 eq) at 70° C. for 17 h, followed by purification by preparative HPLC provides the sulfamides.

The following assays may be employed in ascertaining the degree of activity of a compound as a 15-LO inhibitor. Compounds described in the following Examples have demonstrated measurable activity as 15-LO inhibitors. The inhibitory activity of the Examples against purified 15-LO enzyme was determined using a standard colorimetric assay in which the lipid hydroperoxide product of either linoleic or arachidonic acid [13-hydroperoxyoctadecadienoic acid (13-HPODE) and 15-hydroperoxyeicosatetraenoic acid (15-HPETE), respectively] oxidizes Fe2+ under mildly acidic conditions [Jiang et al, Lipids (1991), 26:10, 853-856]. The Fe3+ forms a chromospheres with xylenol orange that absorbs strongly at 560 nm. Inhibitory activity was compared to an uninhibited (maximal) reaction to yield % inhibition (compound concentration in which enzyme activity is reduced by 50% is termed the IC50). 15-LO enzyme was obtained from phenylhydrazine-treated rabbits and purified according to the method of Rapoport et al [European Journal of Biochemistry (1979) 96:545-561]. In addition to the colorimetric assay, a standard spectrophotometric kinetic assay [Gan et al, J. Biological Chemistry (1996), 271:41; 25412-2541877] was also employed to measure compound activity as 15-LO inhibitors. This assay determines enzyme activity by monitoring the increased absorbance at 234 nm that results from conjugated diene formation of the metabolized substrate. Reactions were carried out 3 minutes and the linear part of the curve was utilized to calculate reaction rates. IC50 calculations were as described for the colorimetric assay.
