Enalaprilat Dihydrate (C007B-154459)

InformationEnalaprilat (MK-422) is anangiotensin-converting enzyme (ACE)inhibitor withIC50of 1.94 nM.In vitroEnalaprilat has high affinity for human endothelial ACE with IC50 of 1.94 nM in vitro binding assay by displacing a saturating concentration of [125I]351A, a radiolabeled lisinopril analogue from ACE binding sites, and shows bradykinin/angiotensin I selectivity ratio of 1.00 calculated from double displacement experiments. Enalaprilat has the strong inhibitory effect on Aβ42-to-Aβ40-converting activity found in the N-domain of ACE, exhibiting a 10-fold lower IC50 (0.003~0.01 μM) than captopril (0.03~0.1 μM). Enalaprilat (100 nM) blocks protein kinase C epsilon by directly activating bradykinin B1 receptor at the canonical Zn2+ binding site, leading to prolonged nitric oxide (NO) production in cytokine-treated human lung microvascular endothelial cells. Enalaprilat attenuates the IGF-I induced neonatal rat cardiac fibroblast growth (30% reduction) in a concentration-dependent fashion, with IC50 of 90 mM.In vivoEnalaprilat has unfavourable ionisation characteristics to allow sufficient potency for oral administration, thus Enalaprilat is only suitable for intravenous administration, which is overcome by the esterification with ethanol to produce Enalapril. Administration of Enalaprilat induces a significant reduction of MAP at 70 minutes compared with the placebo group during haemorrhagic shock in rats, and results in a 50% reduction of CO, a general tendency of EB extravasation which is significant in the kidney and lungs, and a significant increase in ileal EB extravasation (53%). Enalaprilat has no effect in nonhypertrophied hearts, but significantly attenuates the greater increase in left ventricular end-diastolic pressure in hypertrophied hearts compared with no drug.Cell Datacell lines：Concentrations：Dissolved in DMSO, final concentrations 1 nM - 10 μMIncubation Time：24 hoursPowder Purity:≥99%.
