Description

LKY-047, a Decursin derivative, is a potent and selective reversible competitive cytochrome P45022J2 (CYP2J2) inhibitor with an IC50 of 1.7 μM. LKY-047 is inactive against other human P450s, such as CYPs 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A[1].

IC50 & Target[1]

CYP2J2

1.7 μM (IC50)

In Vitro

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
