derivatives via intramolecularoxidative coupling of thiosemicarbazide, using the in situ generated hypervalent iodine(III) reagents is developed. The protocol can be carried out smoothly and provides a variety of thiadiazole derivatives in moderate to excellent yields.Graphical AbstractA highly efficient method for the synthesis of thiadiazole derivatives via PhI-catalyzed intramolecularoxidative coupling

perspective, heterocycliccompounds namely thiazolylhydrazones, furan, tetrazole, triazole and thiadiazoline derivatives were synthesized and tested in vitro against seven clinical importance Cryptococcus and Candida species. In this study, virtual screening techniques were applied using a scaffold-hopping database, FDA approved drugs and a ZINC subset. Some of the compoundsevaluated showed promising

4-triazoles derivatives (5a–5f) are reported. A new series of pyridine substituted 1,2,4-triazoles was synthesized and tested for in vitro studies, acetylcholinesterase (AChE) inhibition assay, kinetics mechanism studies and chemical characterization (1HNMR and 13CNMR analysis). The acetylcholinesteraseinhibition activity of the compound 5f (IC50 ± SEM = 0.0249 ± 0.01 µM) was maximum as compared to the
Eighteen new hydrazino-1,3-thiazole derivatives were evaluated against 8 strains of multi-resistant Candida spp. Introduction of an indolyl moiety linked to the hydrazone function enhanced the in vitro anti-Candida activity, with an activity spectrum towards Candida albicans strains. Introduction of a (S)-2-aminoethyl chain on the thiazole nucleus largely enhanced the in vitro antifungal activity, with a selectivity oriented towards non-C. albicans species. (C) 2013 Elsevier Ltd.
