ET_B Inhibitor

RES-701-3 peptide TFA is a class II lasso peptide. RES-701-3 peptide TFA can be isolated from the fermentation broth of Streptomyces species. RES-701-3 peptide TFA potently inhibits the binding of ET-1 to ET_B, with an IC₅₀ of approximately 5-10 nM. RES-701-3 peptide TFA is applicable to research related to systemic hypertension, myocardial infarction, and myocardial ischemia.

Schisantherin D is a lignan. Schisantherin D can be isolated from Kadsura interior. Schisantherin D downregulates the expression of ETBR and inhibits the secretion of ECM and ET-1. Schisantherin D alleviates EtOH + ET-1-induced hepatocyte cytotoxicity. Schisantherin D potently inhibits HIV replication in cells.

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 K_i 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.
