| Three novel Schiff bases: salicylaldehyde methanesulfonylhydrazone (1), 2-hydroxyaceto-phenone methanesulfonylhydrazone (2) and 2-hydroxy-1-naphthaldehyde methanesulfonylhy drazone (3) have been synthesized. Compounds 1-3, as well as acetone methanesulfonylhydra zone (4) have been characterized by TLC, 'H NMR and IR spectra. The spectroscopic results for 1-3 have revealed the presence of an intramolecular hydrogen bond between the hydroxyl group and the imine N atom. The conformational isomerism of 1-4 with respect to the rota tions around the SN and NN bonds have been studied by the method of molecular mechanics. Compounds 1-4 and methanesulfonylhydrazine exhibit antibacterial and cytotoxic effects. | | | |
