Abstract:

In view of applications of N-glycosylated compounds in medicinal chemistry and in many other ways, herein the synthesis of novel N-glycosyl hydrazino carbothioamides is reported. New N-glycosyl hydrazino carbothioamides were synthesized by the condensation of per-O-acetyl glycosyl isothiocyanate with different aromatic hydrazides. The newly synthesized compounds were characterized by using the IR, 1H NMR and mass spectral studies. Antimicrobial evaluation of the synthesized N-glycosyl hydrazino carbothioamide was also examined. Antimicrobial activities of the synthesized compound were evaluate

ABSTRACT. The synthesized Zeolite A/ZnCl2 nanoparticles via the hydrothermal route were characterized using FTIR, XRD, and SEM/EDAX techniques. The characterized catalyst was used for the eco-friendly synthesis of 4,5-dihydro-pyrazole-1-carbothioamide derivatives. Under solvent-free conditions, a multi-component reaction between hydrazine, isothiocyanate, and chalcone was done with a prepared nano-catalyst as an inexpensive, recyclable, easy-to-get, and nontoxic catalyst. The molecular docking study explained that dihydro-1-carbothioamide pyrazoles can be considered COVID-19 main protease (Mpr
