AHU-377 hemicalcium salt
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].
