Proceeding from the fact that some widely used antibacterial preparations (furacilin, furazolidone, ftivazide) contain hydrazone groups, we decided to synthesize a series of pyrazole-4-carboxylic acid hydrazides, modify these compounds so as to obtain N-(4- pyrazoyl) hydrazones, and study the antibacterial properties of the products. Hydrazides IIIa– IIIg were synthesized based on the previously described pyrazole-4-carboxylic ...
