| Abstract: | Three novel series of benzo[b]thiophene derivatives bearing various hydrazone, hydrazine and 1,3,4-oxadiazole moieties were synthesized as potential antidepressant agents. 22 Compounds were evaluated for their in vitro inhibitory effect on monoamine oxidase enzyme (MAO) type A. Several compounds inhibited MAO stronger than pargyline hydrochloride. Maximum inhibitions of 83% and 90% were observed with 1-benzyl-2-(3-chlorobenzo[b]thienyl-2-carbonyl)hydrazine (24) and 1-[2-(4-chlorophenyl)ethyl]-2-(3-chlorobenzo[b]thienyl-2- carbonyl)hydrazine (35), respectively. |
