Sitaxsentan sodium (Standard)
Sitaxsentan (sodium) (Standard) is the analytical standard of Sitaxsentan sodium (IPI 1040 sodium; TBC11251 sodium) (HY-11103). This product is intended for research and analytical applications. Sitaxsentan sodium is a potent, selective and orally active endothelin A receptor (ETA) antagonist with an IC50 of 1.4 nM and a Ki of 0.43 nM. Sitaxsentan sodium exhibits an IC50 for the ETB receptor of as high as 9800 nM. Sitaxsentan sodium is metabolized by CYP2C9 and CYP3A4, normalizes shunt-induced endothelial abnormalities, restores BMPR signaling, and suppresses pulmonary vascular remodeling and hemodynamic deterioration. Sitaxsentan sodium can be applied in the research of pulmonary arterial hypertension and portopulmonary hypertension.
