Synthesis and antimicrobial activity of some imidazo-[1,2-a]pyridine-2-carboxylic acid arylidenehydrazide derivatives
(2001)
Imidazo[1,2-a]pyridine-2-carboxylic acid, ethyl esters were reacted with hydrazine hydrate to furnish imidazo[1,2-a]pyridine-2-carboxylic acid hydrazide. The hydrazides formed were treated with various aldehydes to obtain ...
Synthesis of novel thiazolylpyrazoline derivatives and evaluation of their antimicrobial activities and cytotoxicities
(Scientific Technical Research Council Turkey-Tubitak, 2016)
Several novel thiazolylpyrazoline derivatives were synthesized by reacting substituted 3,5-diaryl-1-thiocarbamoyl-2-pyrazolines with phenacylbromides. The structures of the synthesized compounds were confirmed by IR, H-1 ...
