WebIn contrast, the monoamine oxidase inhibitor iproniazid produced an antidepressant effect when administered to tubercular patients; iproniazid was later found to improve mood in depressed nontubercular patients. For many years, the neurobiological basis of depression has been linked to the mechanism of action of antide-pressants. WebMechanism of action. Isoniazid is a prodrug and must be activated by bacterial catalase. Specficially, activation is associated with reduction of the mycobacterial ferric KatG catalase-peroxidase by hydrazine and reaction with oxygen to form an oxyferrous enzyme complex. Once activated, isoniazid inhibits the synthesis of mycoloic acids, an ...
