CP-346086 dihydrate is a potent and orally active inhibitor of microsomal triglyceride transfer protein (MTP), exhibiting an IC50 value of 2.0 nM for both human and rodent MTP. This compound effectively lowers plasma cholesterol and triglyceride levels in vivo.

MTP:2.0 nM (IC50)

CP-346086 (0.1-1000 nM) dose-dependently inhibits human MTP-mediated triglyceride transfer between vesicles with an IC 50 of 2.0 nM[1]. CP-346086 (24 h) inhibits apolipoprotein B (apoB) and triglyceride secretion (IC 50 =2.6 nM) from Hep-G2 cells without affecting apoA-I secretion or lipid synthesis[1].

CP-346086 (1-100 mg/kg; oral gavage once daily for 2 weeks) reduces plasma total, VLDL, and LDL cholesterol and triglycerides in mice[1]. CP-346086 (25 mg/kg; a single p.o.) results in an almost complete inhibition of Tyloxapol-induced triglyceride accumulation in fasted rats[1]. CP-346086 (0.1-10 mg/kg; a single p.o.) reduces acute plasma triglyceride in mice[1]. Animal Model: B6CBAF1J mice[1]Dosage: 1, 2, 10, 20, 100 mg/kg Administration: Oral gavage once daily for 2 weeks Result: Lowered total, VLDL, and LDL cholesterol and triglycerides dose dependently with 23%, 33%, 75%, and 62% reductions at 10 mg/kg/day.
