Biochem/physiol Actions

Sitaxentan (Sitaxsentan) is a potent and selective endothelin ET(A) receptor antagonist once used in the treatment of pulmonary arterial hypertension (PAH), but removed from the market because of hepatotoxicity. It is over 6000-fold selective for the the ETA receptor subtype with an IC50 of 1 nM for ETA versus an IC50 of 9800 nM for ETB.
Sitaxsentan prevents shunt mediated elevation of pulmonary vascular resistance (PVR). Sitaxsentan effectively inhibits basolateral Na+-taurocholate cotransporting polypeptide (NTCP), organic anion-transporting polypeptides (OATPs) and bile salt export pump (BSEP).

Tissue cholesterol accumulation, macrophage infiltration, and inflammation are features of atherosclerosis and some forms of dermatitis. HDL and its main protein, apoAI, are acceptors of excess cholesterol from macrophages; this process inhibits tissue inflammation. Recent epidemiologic and clinical trial evidence
