BQ-788 is a selective and potent ETB receptor antagonist with potential hypertensive activity.BQ-788 inhibits ET-1 binding to ETB receptors and inhibits exogenous ET-1-induced elevation of coronary artery perfusion pressure.

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

RO 46-8443 is the first non-peptide endothelin ETB receptor selective antagonist. RO 46-8443 displays up to 2000-fold selectivity for ETB receptors both in terms of binding inhibitory potency and functional inhibition.

ETB067, an H-89 analog, acts as a PKA and AKT1 inhibitor with specificity on no longer inhibiting CAMK2B and neither affecting viability of mice nor causing any detectable tissue damage at the dose given.

Etbicyphat (Trimethylopropane phosphate), a potent competitive antagonist of GABA(A) receptors, binds to GABA(A)-benzodiazepine receptors and induces epileptiform activities in hippocampal CA1 neurons.

Riltovetbart is a monoclonal antibody against IL-13, the isotype control is IgG2 κ, and its origin is canine.

Enrasentan (sb-217242) is a mixed antagonist of ET(A) and ET(B) receptors that reduces blood pressure, prevents cardiac hypertrophy, and protects myocardial function.

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.

Aprocitentan (ACT-132577) is ETA and ETB antagonist .

IRL-1038 TFA is a selective and potent endothelin B (ETB) receptor antagonist that inhibits endothelin-induced endothelium-dependent relaxation and can be used in the study of cardiovascular disease.

Edonentan is A potent endothelin A (ETA) receptor antagonist that can be used to study heart failure.

Nebentan potassium (YM598) is an orally active and selective nonpeptide endothelin receptor (ETA receptor) antagonist.Nebentan potassium inhibits pulmonary arterial hypertension and may be useful in the study of neurologic and cardiovascular diseases.

N-(6-chloro-5-(2-Methoxyphenoxy)-2-(pyridin-4-yl)pyriMidin-4-yl)-5-Met inhibits endothelin binding to membranes from CHO cells carrying human ETA receptor and human ETB receptor with IC50 of 268nM and 1810nM, respectively.

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.

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).

BQ-788 sodium salt is a potent and selective antagonist of ETB receptor [ETB receptors] with an IC50 of 1.2 nM in human Girrardi heart cells.

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.

PD-159020 is a non-selective antagonist of ETA ETB (hETA and hETB) with IC50 values of 30 nM and 50 nM, respectively.

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-1620 is an effective and selective agonist of endothelin receptor type B (ETB) (Ki: 16 pM).
