Designing 2-aminoimidazole alkaloids analogs with anti-biofilm activities: Structure–activities relationships of polysubstituted triazoles
摘要:
In order to discover novel probes that may help in the investigation and the control of bacterial biofilms, we have designed a library of triazole-based analogs of 2-aminoimidazole marine alkaloids: naamine A and isonaamine A. Twenty-two compounds were screened for their biofilm inhibitory activity against two strains of Gram-negative bacteria. Four compounds were shown to act as non-toxic inhibitors of biofilm development without effect on bacterial growth even at high concentrations (100 mu M). (C) 2011 Elsevier Ltd. All rights reserved.
An unprecedented approach that enables the direct and selective preparation of 1,5-disubstituted 1,2,3-triazolesfrom abundantly available building blocks such as primary amines, enolizable ketones and 4-nitrophenyl azide as a renewable...
Multi-component reaction for the preparation of 1,5-disubstituted 1,2,3-triazoles by in-situ generation of azides and nickel-catalyzed azide-alkyne cycloaddition
An efficient one-pot procedure combining bromide conversion into azide followed by NiAAC for the preparation of 1,5-disubstituted 1,2,3-triazoles has been developed. This procedure prevents the use of isolated azides, which are insufficiently commercially available and could be potentially unstable and difficult to handle. Moreover, this one-pot method tolerates a broad range of functional moieties

A regioselective and tunable synthesis of 1,5-disubstituted 1,2,3-triazloles from oxidative and eliminative [3+2] cycloadditions of nitroolefins and organic azides under solvent-free condition in the presence and absence of commercially available CuO nanoparticle catalyst is described. In the presence of the catalyst under solvent-free condition, nitro group is retained in the product while it gets eliminated in the absence of the catalyst. (C) 2016 Elsevier Ltd.
