How to use

In Vitro:

FPL 62064 inhibits both 5-1ipoxygenase (IC50 of 3.5 μM for RBL-1 cytosolic 5-1ipoxygenase) and prostaglandin synthetase (IC50 of 3.1 μM for seminal vesicle prostaglandin synthetase ) with equal facility in the isolated enzyme screens. However in the intact RBL-I cell prostaglandin synthetase (IC50 of 3.6 μM) is more readily inhibited by FPL 62064 than is 5-1ipoxygenase (IC50 of 31 μM). This difference in sensitivity is not reflected in the mouse macrophage where the IC50s for leukotriene (IC50 of 0.72 μM) and prostaglandin (IC50 of 0.43 μM) production are similar.

In Vivo:

FPL 62064 (5-20 mg/kg; intraperitoneal injection; female LACA mice) treatment inhibits peritoneal inflammation induced by immune-complex.
