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.

Several triazoles have been synthesized. They were obtained by a Cu-catalyzed cycloaddition of azides and alkynes. The reaction takes place in aqueous media under microwave irradiation using a copper catalyst based on porous glass. The products have been characterized by infrared, gas chromatography-mass spectrometry, H-1 NMR, and C-13 NMR in addition to melting=point determination. Furthermore the in situ building of some azides and alkynes and the influence of the used metal species was investigated.
