Meranzin is a coumarin that has been found in Murraya exotica and has diverse biological activities.1,2 It is cytotoxic to NSCLC-N6 and KB cancer cells (IC50s = 14.6 and 12.3 ?g/ml, respectively).2 Meranzin (10 mg/kg) increases the latency to paw withdrawal in the hot plate test and reduces xylene-induced ear edema in mice.1 It decreases paw edema induced by carrageenan in rats when administered at the same dose.
