A series of pyrazine-2-carboxylic acid hydrazide derivatives were synthesized and screened for their activity against Mycobacterium tuberculosis. The results show that pyrazine-2-carboxylic acid hydrazide hydrazone derivatives 3a-1 were less active than pyrazinamide. In contrast, the N-4-ethyl-N-1-pyrazinoyl-thiosemicarbazide 4 showed the highest activity against M. tuberculosis H(37)Rv (IC90 = 16.87 mu g/mL). Details of the structure-activity and structure-cytotoxicity relationships are discussed. (C) 2010 Elsevier Masson SAS. All rights reserved.
Synthesis and docking studies of pyrazine–thiazolidinone hybrid scaffold targeting dormant tuberculosis
against current antimycobactrial drugs. To address this issue, we report herein the synthesis of N-(4-oxo-2 substituted thiazolidin-3yl) pyrazine-2-carbohydrazide derivativesdesigned by following the molecular hybridization approach using pyrazine and thiazolidenone scaffolds. The compounds were evaluated against MTB H37Ra and Mycobacterium bovis BCG in dormancy model. Most of the compounds had IC50
