Biological Activity

[Description]:

Lomitapide (AEGR-733; BMS-201038) is a potent inhibitor of microsomal triglyceride-transfer protein (MTP) with an IC50 of 8 nM in vitro.

[Target]

IC50: 8 nM (MTP)[1]

[In Vitro]

Lomitapide is an oral microsomal triglyceride transfer protein (MTP) inhibitor indicated for the treatment of patients with HoFH, a rare form of hypercholesterolemia that can lead to premature atherosclerotic disease. Lomitapide undergoes hepatic metabolism via cytochrome P-450 (CYP) isoenzyme 3A4 and interacts with CYP3A4 substrates including atorvastatin and simvastatin[2].

[In Vivo]

The use of lomitapide alone or in combination with other lipid-lowering modalities reduces plasma concentrations of low density lipoprotein cholesterol (LDL-C) by a mean of more than 50%. Lomitapide is associated with significant gastrointestinal adverse effects and increases in hepatic fat levels. The bioavailability of the 50-mg lomitapide capsule is 7.1%. The mean half-life of lomitapide is 39.7 hours[2]. Single-dose administration of lomitapide is shown to reduce serum triglycerides by 35% and 47% at 0.3- and 1-mg/kg doses, respectively. Multiple-dose treatment with lomitapide also results in dose dependent decrease in triglycerides (71%–87%), nonesterified fattyacids(33%–40%), and LDL-C(26-29%)[3].

[Animal admin]

Rats: BMS-201038 is formulated in 0.1% hydroxyl ethyl cellulose and 0.5% Tween 80 in deionized water. Rats in the control group are administered vehicle (2 mL/kg) p.o. Fasted rats are administered 0.3 and 1 mg/kg, p.o., BMS-201038, followed 1 h later by 250 mg/kg, i.v., Triton WR1339. Blood samples are obtained from rats up to 240 min after Triton WR1339 injection to estimate serum triglyceride concentrations. For evaluation of post-prandial lipaemia, fasted rats are administered 0.3 and 1 mg/kg, p.o., BMS-201038, followed 1 h later by a corn oil bolus (6 mL/kg) by oral gavage. Blood samples are again collected up to 1440 min after corn oil administration for the estimation of serum triglyceride concentrations[3].
