Synthesis and Biological Activity of Novel 4-/5-/6-/7-Nitro-N ′-(4-Aryl-1,3-Thiazol-2-yl)1H-Indole-2-Carbohydrazide Derivatives

Abstract

New 4-/5-/6-/7-nitro-N′-(4-aryl-1,3-thiazol-2-yl)-1H-indole-2-carbohydrazides (4a–t) were prepared by treating respective nitroindole thiosemicarbazide with aromatic acylbromides. The newly synthesized compounds were characterized by analytical and spectral data. The compounds were also screened for antifungal and antibacterial activity. Some of the compounds exhibited promising antimicrobial activity.
