tcsc3409 LCZ696

LCZ696 is a dual angiotensin II receptor and neprilysin inhibitor.

In Vitro: LCZ696 is a single molecule that is comprised of molecular moieties of valsartan, an ARB, and AHU377, a neprilysin inhibitor (1:1 ratio)^[1].

In Vivo: LCZ696 exerts a blood pressure lowering effect. Blood pressure reduction by LCZ696 is associated with a significant increase in urinary sodium excretion and sympathetic activity suppression. LCZ696 significantly ameliorates cardiac hypertrophy and inflammation, coronary arterial remodeling, and vascular endothelial dysfunction in high-salt loaded SHRcp compared with valsartan^[1]. The neprilysin inhibitor component of LCZ696, LBQ657, inhibits hypertrophy but not fibrosis. The angiotensin receptor blocker component of LCZ696, valsartan inhibits both hypertrophy and fibrosis. Dual valsartan+LBQ augment the inhibitory effects of valsartan and the highest doses completely abrogate angiotensin II-mediated effects^[2]. Pre-treatment with LCZ696 reduces the ischemic area. The decrease in cerebral blood flow in the peripheral region of the ischemic area is significantly attenuated by pre-treatment with LCZ696. LCZ696 pre-treatment significantly decreases the increase of superoxide anion production in the cortex on the ischemic side^[3].
