Avosentan (Standard)

Description

Avosentan Standard is the analytical standard of Avosentan HY-15195 . This product is intended for research and analytical applications. Avosentan is an orally active endothelin ETA receptor antagonist. Avosentan can block the ETA receptor, thereby reducing vascular contraction, and exerting a renal protective effect. Avosentan inhibits vascular contraction caused by ET-1 and alleviates the reduction in retinal and optic nerve head blood flow induced by it, lowering intraocular pressure in the glaucoma monkey model. Avosentan non-specifically blocks ETB receptors at high doses, inhibiting ETB-mediated diuresis and natriuresis, and may cause fluid retention. Avosentan can be used to reduce proteinuria with diabetic nephropathy, but induces significant fluid overload and congestive heart failure.
