Abstract:
:Nineteen 5-nitrothiazolylthiosemicarbazones were synthesized from 5-nitrothiazole by three-step synthesis and evaluated for in vitro activities against seven mycobacterial species. Among them, N-(5-nitro-1, 3-thiazol-2-yl)-2-((Z)-4-[(phenylmethyl)oxy]phenylmethylidene)hydrazine-1-carbothioamide (4m) was found to be the most active compound with a minimum inhibitory concentration (MIC) of 0.23 microM against Mycobacterium tuberculosis H37 Rv, and was three times more potent than isoniazid and equally active as rifampicin. Compound 4m also inhibited six non-tubercular mycobacteria with MICs ranging from 1.88 to 30.25 microM.
