Synthesis, structure elucidation and antimicrobial activity of some 3-hydroxy-2-naphthoic acid hydrazide derivatives

Abstract

In this study, some 1,4-disubstituted thiosemicarbazide, 1,2,4-triazole and 1,3,4-thiadiazole type novel compounds derived from 3-hydroxy-2-naphthoic acid hydrazide were synthesized to screen for their antimicrobial activity. The structures of these substances were elucidated using elemental analysis and UV, H-1 NMR, and mass spectral methods. All of these compounds were tested in vitro for their antibacterial and antifungal activity. (C) 1998 Elsevier Science S.A. All rights reserved.
