Synthesis and preliminary biological evaluation of novel N-(3-aryl-1,2,4-triazol-5-yl) cinnamamide derivatives as potential antimycobacterial agents: an operational Topliss Tree approach.

A series of novel N-(3-aryl-1,2,4-triazol-5-yl) cinnamamide derivatives were designed on basis of structural similarity to the known FAS II inhibitors. Topliss operational method was used to optimize the potency of molecules. The minimum inhibitory concentration (MIC) of all synthesized compounds was determined against Mycobacterium tuberculosis H(37)R(v) using resazurin microtitre assay (REMA) plate method.

Novel molecular hybrids of cinnamic acids and guanylhydrazones as potential antitubercular agents.

In an attempt to identify potential new agents active against tuberculosis, 20 novel phenylacrylamide derivatives incorporating cinnamic acids and guanylhydrazones were synthesized using microwave assisted synthesis. Activity of the synthesized compounds was evaluated using resazurin microtitre plate assay (REMA) against Mycobacterium tuberculosis H37Rv. Based on empirical structure-activity relationship data it was observed that both steric and electronic parameters play major role in the activity of this series of compounds.
