The present invention relates to a novel compound for inhibiting Fab I involved in bacterial fatty acid biosynthesis. This application claims priority under 35 U.S.C. 119(e) to the Provisional application 60/726,814, filed on Oct. 13, 2005, entitled “Novel Fab I Inhibitor And Process For Preparing Same,” and to Provisional application 60/827,029 filed on Sep. 26, 2006, both of which are hereby incorporated by reference.
Fatty acid synthase (FAS) is involved in the overall biosynthetic pathway of saturated fatty acids in all organisms, but the structural organization of FAS varies considerably among them. The distinctive characteristics of FAS of vertebrates and yeast are that all enzymatic activities are encoded on one or two polypeptide chains, and that the acyl carrier protein (ACP) exists in the form of a complex. In contrast, in bacterial FAS, each of synthetic steps is catalyzed by a distinct, mono-functional enzyme and the ACP is a discrete protein. Therefore, it is possible to selectively inhibit bacterial FAS by blocking one of the synthetic steps using an inhibitory agent.
NADH-dependent enoyl-ACP reductase (Fab I) is involved in the last step of the four reaction steps involved in each cycle of bacterial fatty acid biosynthesis. (See Payne et al., Drug Discovery Today 6, 2001, 537-544). The first step, the condensation of malonyl-ACP with acetyl-CoA (Fab H), is catalyzed by β-ketoacyl-ACP synthase. The second step is ketoester reduction by NADPH-dependent β-ketoacyl-ACP reductase (Fab G). Subsequent dehydration by β-hydroxyacyl-ACP dehydrase (Fab A or Fab Z) leads to trans-2-enoyl-ACP. Finally, in the fourth step, trans-2-enoyl-ACP is converted to acyl-ACP having two additional carbon atoms by Fab I. Such a cycle is repeated, eventually leading to palmitoyl-ACP (16C), whereupon the cycle is stopped due to inhibition of Fab I by palmitoyl-ACP (see Heath et al., J. Biol. Chem. 271, 1996, 1833-1836). Thus, Fab I is the biosynthetic enzyme in the overall synthetic pathway of bacterial fatty acid biosynthesis.
Recent studies have shown that Fab I is the target for a broad spectrum antibacterial agent such as triclosan (see McMurry et al., Nature, 1998, 394, 531-532) or diazaborine (see Baldock et al., Science, 1996, 274, 2107-2110). Also, diazaborine has been reported to function as an irreversible inhibitor of Fab I through the formation of a covalent complex with Fab I (see Baldock et al., Biochem. Pham., 1998, 55, 1541-1549), while triclosan is a reversible inhibitor of Fab I (see Ward et al., Biochem., 38, 12514-12525).

A solution of pentanol (2.7 g, 31 mmol) and tert-butoxide (3.5 g, 31 mmol) in solvent of tert-butanol was stirred for 1 hr at room temperature followed by addition of 4-nitropyridine-N-oxide (4 g, 28.6 mmol). After the reaction was done, the resulting solution was worked up with ethyl acetate and water, separated and the organic solvent was dried completely. After the addition of toluene, the solvent was removed under a reduced pressure. Acetic anhydride (40 ml) was added to the residual mixture and refluxed for 3 hrs. Acetic anhydride was dried completely followed by adding of MeOH (20 ml) and 3N NaOH (5 ml) and stirring 1 hr. MeOH was dried adequately then the residual mixture was made neutral with 6N HCl. The resulting solution was extracted with Ethyl acetate (80 ml) and subjected to silica gel column chromatography (ethyl acetate/MeOH, 10:1) to obtain the titled compound (2.3 g, 56%).

Antibacterial activities of the compounds synthesized in the Examples were assessed by measuring their MIC values for standard strains. Specifically, MIC value was measured by conducting the following steps: diluting a test compound according to a two-fold dilution method; dispersing the resulting dilution in a Müller-Hinton agar broth; inoculating 2 ml of the standard strain culture having a concentration of 107 cfu (colony forming unit)/ml; and incubating the mixture for 20 hrs at 37° C. The resulting MIC values were in the range of 128 to 0.2 μg/ml, preferably, 1 to 0.2 μg/ml. These results reveal that the compounds of the present invention have superior antibacterial activity against various infectious bacterial strains including MRSA strain.
