Sacubitril (formerly known as AHU-377; Entresto) is a novel and potent NEP (neutral endopeptidase 24.11) inhibitor used in combination with valsartan (as LCZ696) for heart failure. It inhibits NEP with an IC50 of 5 nM. Sacubitril is a component of the heart failure medicine LCZ696 (sacubitril in combination with valsartan). Sacubitril is a prodrug that can be activated to LBQ657 by de-ethylation via esterases. LBQ657 inhibits the enzyme neprilysin, which is responsible for the degradation of atrial and brain natriuretic peptide, two blood pressure lowering peptides that work mainly by reducing blood volume.
| ln Vitro |
The compound sacubitril (AHU-377) is a neprilysin inhibitor that is composed of the molecular moieties of valsartan (an ARB) and sacubitril (AHU-377) in a 1:1 ratio. Sacubitril (AHU-377) undergoes enzymatic cleavage of the ethyl ester to generate the active enkephalinase-inhibiting metabolite LBQ657 [2]. There is no inhibition of collagen formation in fibroblasts or cardiomyocyte hypertrophy by the inactive NEPi precursor Sacubitril (AHU-377). Active NEPi LBQ657 did not appear to have any effect on cardiac fibroblasts. Conversely, LBQ657 inhibits cardiomyocyte hypertrophy to a moderate extent [3].

| ln Vivo |
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]. Sacubitril (3, 10, and 30 mg/kg, PO) pretreatment raised ANP-induced plasma cGMP levels in normotensive rats by 2.4, 3.3, and 4.0 folds, respectively (4-hour AUC compared to vehicle)[4]. In Dahl-SS rats, sacubitril (30 and 100 mg/kg, PO) has dose-dependent antihypertensive effects [4].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
