Sulfisoxazole (Sulfafurazole) is a short-acting sulfonamide antibacterial with activity against a wide range of gram-negative and gram-positive organisms.Sulfisoxazole inhibits breast cancer exosome release by targeting endothelin receptor A.

Macitentan (ACT-064992) is an endothelin receptor antagonist utilized in the treatment of pulmonary arterial hypertension (PAH).

Bosentan (Benzenesulfonamide) is a sulfonamide-derived, competitive and specific endothelin receptor antagonist with a slightly higher affinity for the endothelin A receptor than endothelin B receptor. Bosentan blocks the action of endothelin 1, an extremely potent endogenous vasoconstrictor and bronchoconstrictor, by binding to endothelin A and endothelin B receptors in the endothelium and vascular smooth muscle. Bosentan decreases both pulmonary and systemic vascular resistance and is particularly used in the treatment of pulmonary arterial hypertension.

Bosentan hydrate (Ro 47-0203) is a competitive and dual antagonist of endothelin-1 at the endothelin-A (ET-A) and endothelin-B (ET-B) receptors.

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).

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.

Macitentan n-butyl analogue, a derivative of Macitentan, functions as an orally active dual antagonist 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.

A-192621 is a potent, nonpeptide, orally active, and selective endothelin B (ETB) receptor antagonist with an IC50 of 4.5 nM and a Ki of 8.8 nM. A-192621 promotes apoptosis in PASMCs and elevates both arterial blood pressure and plasma ET-1 levels[1][2][3]. Its selectivity is 636-fold higher for ETB than ETA (IC50 of 4280 nM and Ki of 5600 nM).

IRL 2500 is an antagonist of Endothelin receptor with IC50s of 1.3 and 94 nM for Endothelin A receptor and Endothelin B receptor.

Tezosentan is an antagonist of the endothelin receptor (pA2s: 9.5, 7.7 for ETA and ETB receptors, respectively).

Endothelin 1 (swine, human), a synthetic peptide mirroring the sequence of both human and swine Endothelin 1, functions as a robust endogenous vasoconstrictor by interacting with two receptor types, ETA and ETB.
