eta/etb

Macitentan-d4 (ACT-064992 D4) is a deuterated substitute for Macitentan and can be used as a dual antagonist of the non-peptides ETA and ETB (endothelin receptor).Macitentan-d4 is less toxic than Macitentan, has a longer half-life, and can be used to study endothelin receptor-mediated diseases.

Aprocitentan D4 (ACT-132577 D4) is a deuterium-labeled Aprocitentan. Aprocitentan is a major and pharmacologically active metabolite of Macitentan. Aprocitentan is a dual ETA/ETB antagonist (IC50s: 3.4 nM and 987 nM; pA2s: 6.7 and 5.5).

Bosentan-d4, the deuterium-labeled variant of Bosentan, serves as a competitive dual antagonist against endothelin-1 (ET) by targeting both ET A and ET B receptors. It exhibits binding affinities with K i values of 4.7 nM for ET A and 95 nM for ET B in human SMC.

N-Despropyl Macitentan-d4 is a deuterated compound of N-Despropyl Macitentan. N-Despropyl Macitentan has a CAS number of 1103522-45-7. Aprocitentan is ETA and ETB antagonist .
