Sitaxsentan sodium 生物活性

描述 G protein-coupled receptor (GPCR) agonists through their receptors can transactivate protein tyrosine kinase receptors such as epidermal growth factor receptor and serine/threonine kinase receptors most notably transforming growth factor (TGF)-β receptor (TβRI). Several GPCR agonists such as Ang II, thrombin, ET-1 can mediate the transactivation of a multitude of protein tyrosine kinase receptors[3]. Endothelin-1 (ET-1) is a potent vasoconstrictor peptide thought to play a critical role in the pathogenesis and progression of PAH. The biological effects of ET-1 are mediated through the endothelin receptor subtype A (ETA) and endothelin receptor subtype B (ETB). Sitaxsentan Sodium is an ETA-selective endothelin receptor antagonists (ERAs) with IC50 value of 1.4 nM[4]. Patients with New York Heart Association (NYHA) functional class II-IV PAH treated with 100 mg sitaxsentan showed statistically significant improvements in 6-minute walk distance (6MWD) (35 m placebo corrected improvement, p<0.01) and 29% of the sitaxsentan 100-mg patients improved by at least one functional class without any deteriorations[5].
