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).
Ziprasidone, an antipsychotic agent, functions as a dualantagonist of 5-HT (serotonin) and dopamine receptors. Keto Ziprasidone represents an impurity found within Ziprasidone.
Macitentan n-butyl analogue, a derivative of Macitentan, functions as an orally active dualantagonist targeting both endothelin ETA and ETB receptors. This compound shows promise for treating idiopathic pulmonary fibrosis (IPF) and pulmonary arterial hypertension (PAH), leveraging its non-peptide structure for potential therapeutic applications.
