Supplier:  Apexbio Technology LLC A19295.1

Macitentan (CAS 441798-33-0) is a small molecule endothelin receptor antagonist acting as a dual inhibitor of ETA and ETB receptors Experimental data using recombinant ETA-expressing CHO cells show that macitentan exhibits potent inhibition of ET-1 ligand binding with an IC50 of approximately 0 5 nM whereas its inhibitory effect on ETB receptors in similar CHO cell systems is weaker (IC50 391 nM) In vivo rodent studies indicate macitentan rapidly converts into ACT-132577 a circulating metabolite with extended half-life and retained dual receptor antagonism This pharmacological profile makes macitentan relevant for biomedical research on endothelin-associated vascular pathologies
