Application

T863 has been used as a diglyceride acyltransferase (DGAT1) inhibitor:
  • to provide the opportunity to precisely control the DGAT inhibition
  • to treat mouse embryonic fibroblasts (MEFs) to analyse lipid droplet biogenesis
  • to specifically block neutral lipid synthesis and lipid droplet formation in HT-1080 cells
  • to block lipid droplet (LD) formation

Biochem/physiol Actions

T863 is an orally active, selective and potent DGAT1 (Acyl-CoA:diacylglycerol acyltransferase 1) inhibitor that interacts with the acyl-CoA binding site of DGAT1, and inhibits triacylglycerol synthesis in cells. T863 causes weight loss, reduction in serum and liver triglycerides, and improved insulin sensitivity in obese mice.

Foamy macrophages, which have prominent lipid droplets (LDs), are found in a variety of disease states. Toll-like receptor agonists drive triacylglycerol (TG)-rich LD development in macrophages. Here we explore the basis and significance of this process. Our findings indicate that
