Synthesis and biological evaluation of novel thienopyrimidine derivatives as diacylglycerol acyltransferase 1 (DGAT-1) inhibitors.

A novel series of thieno[3,2-]pyrimidine derivatives were synthesised and their inhibitory effects against diacylglycerol acyltransferase 1 (DGAT-1) were assessed. cis-Isomer showed potent and selective inhibitory activity against DGAT-1 in SF9 cells. In addition, had an acceptable pharmacokinetic profile and accumulated mainly in the small intestine and liver. Oral administration of led to a significant reduction in plasma triacylglycerol level during an oral lipid tolerance test (OLTT) in murine and canine models. Taken together, is a high-quality candidate that deserves further investigation.
