Syntheses and Antibacterial Activities of s-Triazole Salicylaldimine Schiff-bases Containing Oxadiazole Oxime-ether Subunits
Abstract:
The reaction of 4-amino-3-phenyl-5-mercapto-s-triazole(1) with β-chloro-phenyl-propanone(2) under refluxing ethanol in the presence of sodium acetate gave amino-triazolyl sulfanyl-phenylpropanone(3). The oximation of compound 3 with hydroxyamine hydrochloride yielded the corresponding oxime(4) followed by the etherification with each of chloromethy-oxadiazoles(5a~5e) and the condensation with salicylaldehyde to form oxime-ethers(6a~6e) and schiff-base oxime-ethers(7a~7e), respectively. The antibacterial activities of the compounds synthesized in vitro to Gram positive bacteria and Gram negative bacteria were tested with the standard 2-fold agar dilution method, and all the tested compounds exhibited relatively better activities against Gram positive bacteria than those against Gram negative bacteria.
