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.

A series of 1,3,4-trisubstituted-1,2,3-triazolium bromide salts were prepared by efficient two-step sequences of azide-alkyne cycloaddition and benzylic substitution. The antimicrobial activity of each triazolium salt and correlating triazole precursor was evaluated using a minimum inhibitory concentration (MIC) assay. MIC activities as low as 1 µM against Gram-positive bacteria, 8 µM against Gram-negative
Copper(I) iodide catalyzed cycloadditions of various combinations of structurally diverse organic azides and terminal alkynes were carried out in a commercially available, polyoxygenated ionic liquid (AMMOENG 100™) without addition of free amine. Unlike the previously tested ionic liquids, this solvent led exclusively to the 1,4-disubstituted triazole regioisomer. alkynes - azides - carbohydrates -
