SYNTHESIS AND RADICAL SCAVENGING PROPERTIES OF SELENOPHENYL BENZAMIDE ANOLOGS
Free radicals that result from different kinds of oxidative stress have been concerned in a variety of human disorders, from cardiac ischemia to those affecting the central nervous system. So, there is an increasing interest in the development of antioxidant molecules that can protect cells against free radical damages. Sets of tetrasubstituted selenophene amides 4a-e were synthesized by reaction of 2-amino-5,6,7,8-tetrahydro-4H-cyclohepta[b]selenophen-3-carbonitrile (2) with benzoyl chloride derivatives and the structures of the amide derivatives were characterized byMS, 1H-NMR, 13C-NMR and IR spectra. The synthesized compounds (4a-e) were evaluated in terms of in vitro. The antioxidant properties were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging properties and IC50 values of the compounds were in the range from 3.794 to 5.644 mg/mL. Compounds 4c and 4e showed predominant radical scavenging activity among the synthesized analogues.
