Biochem/physiol Actions

Macitentan (ACT-064992; actelion-1) is an orally active, potent endothelin (ET) receptor antagonist that blocks ET-1-induced cellular calicum response (IC50 in nM = 0.9/HPASMC, 0.8/RASMC, 1.84/m3T3), as well as ET-1-induced contractions of rat aortic rings (ETA) and S6c-induced rat tracheal rings (ETB) ex vivo (pA2 = 7.6 and 5.9, respectively). Macitentan displays therapeutic efficacy in rat hypertension models in vivo (0.3-100 mg/kg p.o. via single or daily dosing).
Orally active, potent endothelin (ET) receptor antagonist with therapeutic efficacy against hypertension in vivo.

Macitentan, also called Actelion-1 or ACT-064992 [N-[5-(4-bromophenyl)-6-(2-(5-bromopyrimidin-2-yloxy)ethoxy)-pyrimidin-4-yl]-N'-propylaminosulfonamide], is a new dual ET(A)/ET(B) endothelin (ET) receptor antagonist designed for tissue targeting. Selection of macitentan was based on inhibitory potency on both ET receptors and optimization of physicochemical properties to achieve high

Cardiovascular impairment contributes to increased mortality in preterm infants with chronic lung disease. Macitentan, an endothelin-1 receptor antagonist, has the potential to attenuate pulmonary and cardiovascular remodelling. In a prospective randomized placebo-controlled intervention trial, Sprague-Dawley rats were exposed to 0.21
