Synthesis of isonicotinic acid N′-arylidene-N-[2-oxo-2-(4-aryl-piperazin-1-yl)-ethyl]-hydrazides as antituberculosis agents
摘要:
A new series of antituberculosis agents 6-9 was designed, synthesized and evaluated for antituberculosis activity against Mycobacterium tuberculosis H(37)Rv and clinical isolates in an agar dilution method. Compound 9h showed comparable in vitro activity (MIC) to isoniazid against M. tuberculosis H(37)Rv and clinical isolates (sensitive strains) and superior activity against resistant strains of M. tuberculosis.

A new convenient method for the synthesis of earlier unknown 2-substituted derivatives of 5-phenylaminomethyl-2,4-dihydro-3H-[1,2,4]triazol-3-ones was developed. The method involved the alkaline hydrolysis of 2-alkyl-6-phenyl-6,7-dihydro-3H-imidazo[5,1-c][1,2,4]-triazole-3,5(2H)-diones obtained by alkylation of 6-phenyl-6,7-dihydro-2H-imidazo[5,1-c]-[1,2,4]triazole-3,5(2H)-diones.
