How to use

In Vitro:

R-(+)-Tranylcypromine, (±)-Tranylcypromine, and S-(−)-Tranylcypromine competitively inhibits CYP2A6-mediated metabolism of nicotine with apparent Ki values of 0.05 μM, 0.08 μM, and 2.0 μM, respectively, in human liver microsomes. Tranylcypromine (500 μg/mL) severely inhibits bradykinin-stimulated arachidonic acid release in calf aortic endothelial cells. Tranylcypromine inhibits CYP2A6 and CYP2E1 activity with IC50 of 0.42 μM and 3 μM, respectively, in human liver microsomes. Tranylcypromine induces type II and cyclopropylbenzene type I difference spectrum in human liver microsomes.

In Vivo:

Tranylcypromine injection leads to a large, slow increase in motor activity at 5 mg/kg and 10 mg/kg compared with the saline control in male rats, although 2 mg/kg Tranylcypromine does not induce an increase. Tranylcypromine (10 mg/kg) also causes significant decreases in the number of rearing behaviors in male rats.
