Long-chain lipid envelopes are characteristic of mycobacteria such as those that cause tuberculosis and leprosy. Inhibition of fatty acid synthesis or elongation is a strategy demonstrated to be clinically effective against M. tuberculosis. A new class of compounds designed to inhibit the β-ketoacyl synthase reaction of fatty acid synthesis has been developed. Of >30 compounds described, the most active were acetamides containing alkylsulfonyl substituents. Inhibitory activities were acutely sensitive to net charge, chain length, and degree of unsaturation. The most active compound 5 (alkyl = C10) contained a single methylene spacer between the sulfone and carboxamide and exhibited an MIC of 0.75-1.5 μg/mL, comparable to first-line antituberculosis drugs. These compounds are species-specific, exhibiting no significant activity against bacterial species other than M. tuberculosis and closely related strains. The synthesis, biological activity, and specificity of these compounds are described.
