Synthesis of New 7-bromo-5-(2’-chlorophenyl)-3-arylamino-1,2-dihydro-3H-1,4-benzodiazepine Derivatives and Their Influence on Appetite in Rats

Abstract

A series of new 7-bromo-5-(2′-chlorophenyl)-3-arylamino-1,2-dihydro-3H-1,4-benzodiazepine derivatives (II-VIII) were synthesized. The series of synthesized compounds included those that had a substantial effect on appetite in rats, exhibiting both orexigenic and anorexigenic effects at low doses (2.07 – 2.21 μM). Compound VI had anorexigenic activity comparable with that of the hormone leptin, which reduces the appetite and food intake. Co-administration of leptin and III, which exhibited a pronounced orexigenic effect, reduced appetite by 73%.
