Biological Activity
|
CYP2J2 1.7 μM (IC50) |
LKY-047 is a strong competitive inhibitor of CYP2J2-mediated astemizole O-demethylase and terfenadine hydroxylase activity, with Ki values of 0.96 μM and 2.61 μM, respectively. LKY-047 also acted as an uncompetitive inhibitor of CYP2J2-mediated ebastine hydroxylation with a Ki value of 3.61 μM[1].
At 20 μM LKY-047 concentration, approximately 20-fold greater than the Ki value, LKY-047 is found to inhibit CYP2J2 by 85.3%, and only slightly affecting the enzyme activities of the other P450s tested. LKY-047 weakly inhibits CYP2D6 enzyme activity (37.2%) at 20 μM concentration[1].
