A series of substituted 2-polyfluoroalkyl and 2-nitrobenzylsulphanyl benzimidazoles was synthesized. The compounds were evaluated for their activity against four Mycobacterium strains; the activities were expressed as the minimum inhibitory concentration (MIC). The substances tested showed appreciable antimycobacterial activity, particularly 5,6-dichloro-2-nonafluorobutylbenzimidazole (2h), and 5-halogeno-(5a-c) and 4,6-dihalogeno- (5d and 5g) 2-(3,5-dinitrobenzylsulphanyl)benzimidazoles, whose MIC values for Mycobacterium kansasii and Mycobacterium avium exceeded that of isoniazide that was used as a reference compound. Relationships between structure and biological activity of the tested benzimidazole derivatives are discussed. (C) 2004 Elsevier SAS. All rights reserved.
