Sacubitrilat (formerly known as LBQ-657; LBQ657) is the activated form of Sacubitril (AHU-377; AHU-377; Entresto), which is a novel and potent NEP (neutral endopeptidase 24.11) inhibitor used in combination with valsartan (LCZ696) for treating heart failure. Sacubitril is a prodrug that requires esterases to de-ethylate in order to be converted into the active form LBQ657. Atrial and brain natriuretic peptides are two peptides that lower blood pressure primarily by decreasing blood volume. LBQ657 inhibits the enzyme neprilysin, which is in charge of breaking these peptides down.

| ln Vitro |
Sacubitrilat (LBQ657) has a distinct stereocenter and is a single diastereomer. Sacubitrilat exhibits a high inhibitory efficacy of 5 nM upon binding to the active site of NEP via a complicated response network including all of the compound's functional groups [1].

| ln Vivo |
The present study summarizes the pharmacokinetics of sacubitrilat, sacubitrilat la (LBQ657), and the insecticide Sartan after a single sidewall dose of LCZ696 at 400 or 1200 mg during fasting. With a median Tmax of 0.52 h for the 400 mg dose and 1.05 h for the 1200 mg dose, Sacubitril's mean intraperitoneal concentration rose quickly. Sacubitril was next, with corresponding Tmax values of 2.07 and 3.05 h, respectively. The median brasartan Tmax for the 400 mg and 1200 mg dosages of LCZ696 was 2.07 hours. Sacubitril's Cmax shown a dose-proportional increase, while the Cmaxes of both Sacubitril and Sacubitril demonstrated an increase that was not proportionate to the dosages. Arithmetic tools AUC0-24 h and AUClast exhibited less of a dose-proportional increase for Sartan, but increased about dose-proportionally for Sacubitril and Sacubitrilat [2].

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.52 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.52 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
