Thiosemicarbazones of p‐aminobenzoic acid (PABA) were synthesized and tested for their antimicrobial and anticanceractivity. Hydroxamate derivatives 4a–4l were found to have better antimicrobial and anticanceractivity than their acid counterpart. Compound 4d was found to have good antimicrobialactivity against Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Vibrio cholerae, and Bacillus

The present work describes the preparation of new thiadiazoles through a simple intramolecular reaction of mono- and bis-hydrazonoyl halides with methyl hydrogen phenyl carbonimidodithioate or methyl-2-arylidene hydrazinecarbodithioate. The synthetic method involves nucleophilic substitution followed by intramolecular cyclization reactions mediated by evolution of methanethiol. The structures of the title compounds were elucidated by elemental analyses, and FTIR, MS and NMR spectra.
