Synthesis and biological activity of some 3,5-diaryl-1-benzothiazolopyrazoline derivatives: Reaction of chalcones with 2-Hyrazinobenzothiazoles

Abstract

A series of 3,5-diaryl-1-benzothiazolopyrazoline derivatives were synthesized by the reaction of appropriately substituted chalcones and 2-hydrazinobenzothiazole in ethanol. The synthesized heterocycles have been characterized on the basis of their chemical properties and spectroscopic data. These compounds were tested for biological activity against a variety of test organisms.
