Bioactivity | Sacubitril (AHU-377) is a potent and orally active NEP (neprilysin) inhibitor with an IC50 of 5 nM. Sacubitril is a component of the heart failure medicine LCZ696. Sacubitril can be used for the research of heart failure, hypertension and COVID-19[1][2][3]. | ||||||||||||
Target | IC50: 5 nM (NEP) | ||||||||||||
Invitro | Sacubitril (AHU-377) is a single molecule that is comprised of molecular moieties of valsartan, an ARB, and Sacubitril (AHU-377), a neprilysin inhibitor (1:1 ratio). Sacubitril (AHU-377) is converted by enzymatic cleavage of the ethyl ester into the active neprilysin inhibiting metabolite LBQ657[2].The inactive NEPi precursor, Sacubitril (AHU-377), does not inhibit collagen accumulation in fibroblasts nor cardiac myocyte hypertrophy. In cardiac fibroblasts, the active NEPi LBQ657 had no discernible effects. In contrast, LBQ657 modestly inhibits cardiac myocyte hypertrophy[3]. | ||||||||||||
In Vivo | In vehicle-treated dogs, ANF increases urinary sodium excretion from 17.3±3.6 to 199.5±18.4 pequivkglmin. This effect is potentiated significantly in animals which receive Sacubitril (AHU-377). Urinary volume is also potentiated in animals which receive an iv administration of Sacubitril (AHU-377)[1].In normotensive rats, pretreatment with Sacubitril (3, 10 and 30 mg/kg, PO.) augments ANP-evoked plasma cGMP levels by 2.4, 3.3 and 4.0 fold, respectively (4h AUC compared to vehicle)[4].Sacubitril (30 and 100 mg/kg, PO) produces a dose-dependent antihypertensive effect in Dahl-SS rats[4]. | ||||||||||||
