Abstract:

Previously we have reported 5-substituted phenyl-3-(thiophen-2-yl)-4, 5-dihydro-1hpyrazole- 1-carboxamides as a novel class of antidepressants. The aim of the current study is to proposing the reason for such biological activities of the molecules by using molecular docking studies using AutoDock4.2. Using molecular docking studies, we propose that most of the antidepressant molecules showed good binding affinity towards MAO-A than MAO-B which is an effective target for the treatment of depression. The R and S form of thiophene based pyrazolines-carboxamides showed a binding energy and inhibition constant between 7.93 to -8.76 and 1.54 to 0.38 μM toward MAO-A and -6.39 to -8.51 and 20.84 to 0.57 μM toward MAO-B respectively.

Keywords: Antidepressant, pyrazoline, molecular docking, monoamine oxidase.
