Product Description

Sacubitril hemicalcium (also known as AHU377; AHU-377; Entresto) is a novel and potent NEP (neutral endopeptidase 24.11) inhibitor with an IC50 of 5 nM. It is a component of the heart failure medication LCZ696 (sacubitril/valsartan). This prodrug can be converted to LBQ657 by using esterases to de-ethylate it. The blood pressure-lowering peptides atrial and brain natriuretic peptide, which primarily lower blood volume, are broken down by the enzyme neprilysin, which is inhibited by LBQ657.

Biological Activity I Assay Protocols (From Reference)

ln Vitro	Combining the molecular components of valsartan (an ARB) and sacubitril hemicalcium salt (a neprilysin inhibitor) in a 1:1 ratio, sacubitril (AHU-377) is a single molecule. Enzymatic cleavage of the ethyl ester converts sacubitril (AHU-377) to the active enkephalinase-inhibiting metabolite LBQ657 [2]. Sacubitril hemicalcium salt, an inactive NEPi precursor, does not prevent collagen from building up in fibroblasts or cardiomyocyte hypertrophy. There was no discernible impact of active NEPi LBQ657 on cardiac fibroblasts. By comparison, cardiomyocyte enlargement is moderately inhibited by LBQ657 [3].
ln Vivo	Sacubitril (AHU-377) is absorbed quickly in humans (tmax 0.5-1.1 h). The fast conversion of sacubitril hemicalcium salt to LBQ657 results in a tmax in 1.9–3.5 hours. Biologically active LBQ657 has an average half-life of 9.9–11.1 hours [2]. ANF raised urine natriuresis in dogs treated with a vehicle from 17.3±3.6 to 199.5±18.4 pequivkglmin. The effects of sacubitril (AHU-377) were markedly amplified in the animals. Urine production is similarly increased in animals given intravenous Sacubitril (AHU-377) [1].
