Bazinaprine (SR-95,191) is an experimental drug candidate. It is a monoamine oxidase inhibitor (MAOI) which is believed to be useful for the treatment of depression. The drug strongly inhibits type A monoamine oxidase, but only weakly inhibits type B. The effects of the drug are reversible in vivo, but not in vitro.[1] In studies, the chemical has been shown to not interact in vivo with other neurotransmitter or drug receptor sites.[2]
