Abstract

A new series of brominated derivatives of 2, 3-dihydroquinazolin-4(1H)-one were synthesized and their structures were confirmed using IR, NMR and mass spectra. The synthesized derivatives were screened for their in vitro anthelmintic activity. The investigations on interaction of the bioactive compound, 2i with bovine serum albumin (BSA) were evaluated. The quenching mechanism of the compound, 2i was deduced based on the results of Stern-Volmer equation. The number of binding site, prediction of binding site region and the changes in the secondary structure of protein were predicted using various spectroscopic studies.
