In this paper, it is described the synthesis and the evaluation of the leishmanicidal activity of twenty-six eugenol derivatives bearing 1,2,3-triazole functionalities. The evaluation of the compounds on promastigotes of Leishmania amazonensis (WHOM/BR/75/Josefa) showed that eugenol derivatives present leishmanicidal activities with varying degrees of effectiveness. The most active compound, namely
A facile protocol for the regioselective synthesis of 1,4-disubstituted 1,2,3-triazoles via a three-component ‘click’ reaction of alkyl/benzyl bromides, sodium azide, and terminal alkynes catalyzed by an efficient water soluble copper(I) complex has been developed. The halides have been directly converted into 1,2,3-triazoles via in situ generation of azides and hence, handling of hazardous azide intermediates
A series of new 1,2,3-triazolo-phenanthrene hybrids has been synthesized by employing Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. These compounds were evaluated for their in vitro cytotoxic potential against various human cancer cell lines viz. lung (A549), prostate (PC-3 and DU145), gastric (HGC-27), cervical (HeLa), triple negative breast (MDA-MB-231, MDA-MB-453) and breast (BT-549
A sustainable green methodology for the ‘one-pot’ syntheses of 1,2,3-triazolo 3-hydroxy-2-oxindoles from isatin–epoxides has been employed via a CuAAC reaction.
