Actions biochimiques/physiologiques

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).

Extracellular vesicles (EVs) carrying tumor cell-derived programmed death-ligand 1 (PD-L1) interact with programmed death 1 (PD-1)-producing T cells, thus significantly lowering a patient's response to immune checkpoint blockade drugs. No drug that reinvigorates CD8+ T cells by suppressing EV PD-L1

Immune checkpoint therapy (ICT), which reinvigorates cytotoxic T cells, provides clinical benefits as an alternative to conventional cancer therapies. However, its clinical response rate is too low to treat an immune-excluded tumor, owing to the presence of abundant stromal elements

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
