Description | Macitentan (ACT-064992) is an endothelin receptor antagonist utilized in the treatment of pulmonary arterial hypertension (PAH). |
Targets&IC50 | ETB:391 nM, ETA:0.5 nM |
In vitro | In DOCA-salt-induced hypertensive rats, Macitentan (10 mg/kg) demonstrated a dose-dependent reduction in mean arterial blood pressure. Similarly, in a model of pulmonary arterial hypertension using monocrotaline-treated rats, oral administration of Macitentan (30 mg/kg/day) dose-dependently prevented the development of pulmonary arterial hypertension and right ventricular hypertrophy. Additionally, in type 2 diabetic db/db mice, oral Macitentan (25 mg/kg/day) reduced mRNA expression while concurrently enhancing NF-κB activation. |
In vivo | In primary human lung smooth muscle cells (IC50=1 nM), Macitentan inhibits the increase of intracellular calcium ions induced by ET-1. Additionally, Macitentan suppresses ET-1-induced contraction in isolated rat aortic rings. Furthermore, in isolated rat tracheal rings, Macitentan inhibits contraction induced by S6c. |
