A series of new 2-(phenylthio) benzoylarylhydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, (1)H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial
