生物活性:
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).
体内研究:
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.
体外研究:
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.
