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 simple and novel γ-Fe2O3 supported on hydroxyapatite (HAP) heterogeneous catalytic system is described that is useful in the synthesis of disubstituted 1,2,3-triazoles from terminal alkynes and in situ generated organic azide in aqueous media; this green methodology emerges as this new catalyst for the one-pot synthesis of 1,2,3-triazoles can be used in water without the addition of any reagent/base. The catalyst can be successfully recycled five times without significant loss of activity. It is important to note that 100% regioselectivity was observed for the cycloaddition reaction.

Abstract A straightforward method for the synthesis of a new luminescent copper(I) coordination polymer (CP) containing the ligand 1,3-bis(1H-benzotriazol-1-ylmethyl)benzene (L) through a self-assembly process with copper(I) iodide is reported. The CP was characterized by infrared, NMR, UV–Vis and photoluminescence spectroscopy, high resolution mass spectrometry (ESI), elemental and thermogravimetric
