RP 70676 is a potent inhibitor of ACAT , with IC 50 of 25 and 44 nM for rat and rabbit ACAT .
In Vitro
RP 70676 is a potent inhibitor of rabbit arterial ACAT (IC 50 = 40 nM) and has been shown to be an effective inhibitor of ACAT derived from a number of tissues and species including man. The IC 50 values range from 21 nM for hamster liver ACAT to 108 nM for enzyme from the intestine of cholesterol fed rabbits; in human hepatic tissues the mean IC 50 is 44 nM. In whole cell P388D, murine macrophages the compound has an IC 50 of 540 nM. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
