Field of application
RHC 80267 (U-57908) is a potent and selective inhibitor of diacylglycerol lipase (DAGL) (with IC50 of 4 μM in canine platelets). RHC-80267 inhibits cholinesterase activity with an IC50 of 4 μM, thereby enhancing the relaxation evoked by acetylcholine. RHC 80267 also inhibits COX and the hydrolysis of phosphatidylcholine (PC).

Description: RHC 80267 (U-57908) is a potent and selective inhibitor of diacylglycerol lipase (DAGL) (with IC50 of 4 μM in canine platelets). RHC-80267 inhibits cholinesterase activity with an IC50 of 4 μM, thereby enhancing the relaxation evoked by acetylcholine. RHC 80267 also inhibits COX and the hydrolysis of phosphatidylcholine (PC)[1][2][3][4].
Target: IC50: 4 μM (Canine diacylglycerol lipase), 4 μM (Cholinesterase); COX; Phosphatidylcholine[1][3][4]
In Vivo: RHC 80267 (40 μM) enhances contractions induced by U46619 (a thromboxane A2 analog) in human and rat pulmonary arteries (hPAs and rPAs, respectively) and by angiotensin II (ANG II) in rPAs in an endothelium-dependent manner[3].
In Vitro: The potentiation by RHC 80267 of the relaxation to acetylcholine could be caused by the inhibition of cholinesterase: (1) RHC 80267 does not affect the responses to carbachol, the carbamyl derivative of acetylcholine which only differs from acetylcholine by its resistance to hydrolysis by cholinesterase, and (2) the effect of RHC 80267 is mimicked by the inhibitor of cholinesterase neostigmine, RHC 80267 showing no additional effect in the presence of a maximally effective concentration of neostigmine. The determination of the effect of RHC 80267 on the cholinesterase activity of brain homogenate confirmed that RHC 80267 inhibits this enzyme in the same range of concentrations increasing the relaxation to acetylcholine, namely at 1-10 μM[2].

DC44170 Ervogastat Ervogastat (PF-06865571) is a potent and well-tolerated diacylglycerol acyltransferase 2 inhibitor (DGAT2i). Ervogastat alone reduces steatosis and hepatic triglyceride levels in non-alcoholic steatohepatitis (NASH). Ervogastat combination with Clesacostat (an acetyl CoA-carboxylase inhibitor (ACCi)) can be used for the research of NASH with liver fibrosis therapy.
DC42524 YM750 YM-750 is a potent acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor (IC50=0.18 μM). ACAT catalyzes the formation of cholesteryl esters from cholesterol and long-chain fatty-acyl-coenzyme A.
DC28198 RHC 80267 RHC 80267 (U-57908) is a potent and selective inhibitor of diacylglycerol lipase (DAGL) (with IC50 of 4 μM in canine platelets). RHC-80267 inhibits cholinesterase activity with an IC50 of 4 μM, thereby enhancing the relaxation evoked by acetylcholine. RHC 80267 also inhibits COX and the hydrolysis of phosphatidylcholine (PC).
