MGAT2-IN-2 is a potent and selective acyl CoA:monoacylglycerolacyltransferase2 (MGAT2) inhibitor with anIC₅₀of 3.4 nM.

MGAT2-IN-2 (Compound 24d) exhibits potent MGAT2 inhibitory activity with an IC₅₀value of 3.4 nM and a ligand lipophilicity efficiency (LLE) value of 5.4^[1]. MGAT2-IN-2 (Compound 2) exhibits time-dependent inhibition (TDI) of cytochrome P450 3A4 (CYP3A4). Preincubation of MGAT2-IN-2 with microsomes leads to a significant loss of the activity of CYP3A4 relative to that under a condition without preincubation^[2].

Effect of MGAT2-IN-2 on plasma TG is elevated during the oral fat tolerance test in C57BL/6J mice. MGAT2-IN-2 (3, 10 and 30 mg/kg) is orally administered 6 h prior to oil challenge. Pharmacokinetic studies reveal that MGAT2-IN-2 displays a high plasma concentration (AUC_0-8h=842 ngoh/mL) and favorable oral bioavailability (F=52%), which are probably driven by the improved stability against oxidative metabolism and hydrolysis. For evaluating the in vivo efficacy, MGAT2-IN-2 is examined for its effect on hypertriglyceridemia during oral fat tolerance test (OFTT) using C57BL/6J mice. To inhibit the hydrolysis of plasma triacylglycerol (TG) by lipoprotein lipase (LPL), mice are pretreated with an LPL inhibitor, Pluronic F127, permitting measurement of the accumulation of plasma TG following olive oil administration. MGAT2-IN-2 and vehicle are administered 6 h before the oral olive oil load, and plasma chylomicron TG concentrations are monitored for 4 h. MGAT2-IN-2 effectively and dose-dependently suppresses plasma TG elevation after olive oil challenge. The TG-lowering effect of MGAT2-IN-2 is significant (p<0.025) at doses of 10 and 30 mg/kg. A similar effect of reducing the rate of fat entrance into the circulation is observed in MGAT2 gene knockout mice^[1].
