Description

General description

A dichlorobenzimidazolopyrrolidinamide compound that acts as a highly potent PrCP-selective inhibitor (IC₅₀ = 1 nM against human PrCP; IC₅₀ = 2 and 8 nM against mouse PrCP, respectively, in the absence or presence of 1% mouse serum albumin), presumably via non-covalent catalytic site interaction, while exhibiting no significant potency toward panels of ion channels, receptors, and enzymes, including homologous serine proteases QPP, FAP, PEP, ACE2, DPP4, DPP8, and DPP9 (IC₅₀ >25 µM). Oral administration (100 mg/kg/d for 5 d) is reported to result in significant food intake reduction and body fat loss among high fat diet-induced obese mice in vivo.

A dichlorobenzimidazolopyrrolidinamide compound that acts as a highly potent PrCP-selective inhibitor (IC₅₀ in the absence/presence of 1% mouse serum albumin = 1 nM/1 nM and 2 nM/8 nM, respectively, against human and mouse PrCP-catalyzed Mca-APK(Dnp)-OH hydrolysis; Initial [Substrate] = 25 µM), presumably via non-covalent catalytic site interaction, while exhibiting no significant potency toward panels of ion channels, receptors, and enzymes, including homologous serine proteases QPP, FAP, PEP, ACE2, DPP4, DPP8, and DPP9 (IC₅₀ >25 µM). Despite its being a substrate of P-gp efflux transporters and ineffective CNS delivery across blood-brain barrier, peripheral PrCP inhibition via oral administration (100 mg/kg/d for 5 d; [Drug] = 380 nM and 50 nM, respectively, in blood and brain 24 h after last p.o. dosing) is reported to result in significant food intake reduction and body fat loss among high fat diet-induced obese mice (0.73 g fat reduction vs. 0,73 g fat gain in 5 d, respectively, with drug or vehicle treatment) in vivo. Drug treatment among PrCP^-/- obsese mice in comparison, results in only 1.1% weight loss primarily due to a decreased gain in muscle mass and little change in body fat.
