Synthesis and biological activities of triazole derivatives as inhibitors of InhA and antituberculosis agents
摘要:
InhA, the enoyl reductase from the mycobacterial type II fatty acid biosynthesis pathway, is a target for the development of novel drugs against tuberculosis. We exploited copper-catalyzed [3+2] cycloaddition between alkynes and different azides to afford 1,4-disubstituted triazole or alpha-ketotriazole derivatives. Several compounds bearing a lipophilic chain mimicking the substrate were able to inhibit InhA. Among them, 1-dodecyl-4-phenethyl-1H-1,2,3-triazole displayed a minimum inhibitory concentration inferior to 2 mu g/mL against Mycobacterium tuberculosis H37Rv. (C) 2011 Elsevier Masson SAS.

Palladium-catalyzedintramolecular dehydrogenative directarylations of 1,2,3-triazoles were accomplished under ambient pressure of air, which set the stage for a modular synthesis of annulated phenanthrenes through a reaction sequence comprising two distinct catalytic C−H bond functionalization reactions.
