CYP11B2-IN-1 is a CYP11B2 inhibitor with an IC50 of 2.3 nM. CYP11B2-IN-1 inhibits CYP11B1 with an IC50 of 142 nM.
CYP11B2-IN-1 (Compound 32) also inhibits CYP19 with an IC50 of 1021 nM [1] .
In a rhesus pharmacodynamic model, CYP11B2-IN-1 (Compound 32) produces dose-dependent aldosterone lowering efficacy, with no apparent effect on cortisol levels[1].
CYP11B2-IN-1also displays a good rhesus pharmacokinetics profile, with low plasma clearance and acceptable oral exposure.When dosed i.v. at 0.01 and 0.3 mg/kg, CYP11B2-IN-1 produces reductions in aldosterone AUC of 62% and 95%, respectively, compared to baseline[1].
