Chemical synthesis and biological evaluation of triazole derivatives as inhibitors of InhA and antituberculosis agents
摘要:
A series of triazoles have been prepared and evaluated as inhibitors of InhA as well as inhibitors of Mycobacterium tuberculosis H37Rv. Several of these new compounds possess a good activity against InhA, particularly compounds 17 and 18 for which molecular docking has been performed. Concerning their activities against M. tuberculosis H37Rv strain, two of them, 3 and 12, were found to be good inhibitors with MIC values of 0.50 and 0.25 mu g/ml, respectively. Particularly, compound 12 presenting the best MIC value of all compounds tested (0.6 mu M) is totally inactive against InhA. (C) 2012 Elsevier Masson SAS. All rights reserved.

Copper-in-charcoal (Cu/C) is an effective heterogeneous catalyst for tandem diazo transfer/click reactions. In the presence of Cu/C, various azides can be generated in situ from the corresponding amines, and subsequently undergo [3+2] cycloaddition with terminal alkynes to afford triazoles in good yields. The catalyst is also easily recycled.
