AHU-377 hemicalcium salt is a hemicalcium salt form of AHU-377. It is an inhibitor of neprilysin with IC50 value of 5 nM [1].
AHU-377 and the angiotensin II AT1 receptor antagonist valsartan compose LCZ696 in a 1:1 molar ratio. LCZ696 is an angiotensin receptor neprilysin inhibitor. It can reduce blood pressure and may be a novel drug for the treatment of heart failure. AHU-377 is a pro-drug, it can be converted by enzymatic cleavage of the ethyl ester into the active form LBQ657. It is reported that AHU-377(30 and 100 mg/kg, PO) can cause antihypertensive effect in a dose-dependent manner in DAHI-SS rats. But in the DOCA-salt hypertensive rats, it shows a weak reduction [2, 3].

Dicarboxylic acid dipeptide neutral endopeptidase inhibitors.[Pubmed:7752193]
J Med Chem. 1995 May 12;38(10):1689-700.
The synthesis of three series of dicarboxylic acid dipeptide neutral endopeptidase 24.11 (NEP) inhibitors is described. In particular, the amino butyramide 21a exhibited potent NEP inhibitory activity (IC50 = 5.0 nM) in vitro and in vivo. Blood levels of 21a were determined using an ex vivo method by measuring plasma inhibitory activity in conscious rats, mongrel dogs, and cynomolgus monkeys. Free drug concentrations were 10-1500 times greater than the inhibitory constant for NEP over the course of a 6 h experiment. A good correlation of free drug concentrations was obtained when comparing values determined by the ex vivo analysis to those calculated from direct HPLC measurements. Plasma atrial natriuretic factor (exogenous) levels were elevated in rats and dogs after oral administration of 19a. Urinary volume and urinary sodium excretion were also potentiated in anesthetized dogs treated with 21a.
