Antimycobacterial Agents. 1. Thio Analogues of Purine
摘要:
Thio analogues of purine, pyridine, and pyrimidine were prepared based on the initial activity screening of several analogues of these heterocycles against Mycobacterium tuberculosis (Mtb). Certain 6-thio-substituted purine analogues described herein showed moderate to good inhibitory activity. In particular, two purine analogues 9-(ethylcarboxymethyl)-6-(decylthio)9H-purine (20) and 9-(ethylcarboxymethyl)-6-(dodecylthio)-9H-purine (21) exhibited MIC values of 1.56 and 0.78 mug/mL respectively against the Mtb H(37)Rv strain. N-9-Substitution apparently enhances the antimycobacterial activity in the purine series described herein.
