Abstract

Monoacylglycerol Acyltransferase 2 (MGAT2) plays an important role in intestinal fat absorption. We discovered the novel MGAT2 Inhibitor, JTP-103237, and evaluated its pharmacological profile. JTP-103237 selectively inhibited MGAT2 without remarkable species differences and reduced absorbed Lipids in circulation. After lipid administration, JTP-103237 slightly but significantly decreased triglyceride content in proximal small intestine and significantly increased the Lipids content in the distal small intestine. In addition, JTP-103237 significantly increased MGAT substrate (monoacylglycerol and fatty acid) content in the small intestine. JTP-103237 increased plasma peptide YY levels after lipid loading and reduced food intake in a dietary fat-dependent manner. After chronic treatment, JTP-103237 significantly decreased body weight and increased O2 consumption in the early dark phase in high fat diet induced obese (DIO) mice. Moreover, JTP-103237 improved glucose tolerance and decreased fat weight and hepatic triglyceride content in DIO mice. Our findings indicate that JTP-103237 prevents diet-induced Obesity by inhibiting intestinal MGAT2 and has unique properties as a drug for the treatment of Obesity.
