Synthesis, Characterization and Biological Activities of Substituted 1-[Benzothiazol-(1H)-2-yl]-3-phenyl-prop-2-en-1-ones

Abstract

A series of ortho and para substituted 1-[benzothiazol-(1H)-2-yl]-3-phenyl-prop-2-en-1-one derivatives were synthesized from 2-acetyl benzothiazole and ortho and para-substituted benzaldehye using ethanol as solvent. The synthesized compounds were characterized by UV-visible, FT-IR, 1H NMR and mass spectrometry. Antioxidant activities of synthesized compounds have been evaluated by DPPH free radical scavenging activity using ascorbic acid as standard. The standard solution and 1-[benzothiazol- (1H)-2-yl]-3-phenylprop-2-en-1-ones compounds were prepared with different concentrations. Anticancer activity of 1-[benzothiazol-(1H)-2-yl]-3-phenylprop-2-en-1-one and 1-[benzothiazol-(1H)- 2-yl]-3(4-chlorophenyl)prop-2-en-1-one were assigned by MTT assays.
