Abstract

Many studies have been conducted on the selective inhibition of human monoamine oxidase B ( h MAO-B) enzyme using benzylamine-sulphonamide derivatives. Using various chemical modifications on BB-4h , which was reported previously by our team and showed a significant level of MAO-B inhibition, novel benzylamine-sulphonamide derivatives were designed, synthesised, and their MAO inhibition potentials were evaluated. Among the tested derivatives, compounds 4i and 4t achieved IC <subscript>50</subscript> values of 0.041 ± 0.001 µM and 0.065 ± 0.002 µM, respectively. The mechanism of h MAO-B inhibition by compounds 4i and 4t was studied using Lineweaver-Burk plot. The nature of inhibition was also determined to be non-competitive. Cytotoxicity tests were conducted and compounds 4i and 4t were found to be non-toxic. Molecular docking studies were also carried out for compound 4i , which was found as the most potent agent, within h MAO-B catalytic site.
