etb

ETB is a potent inhibitor of Hsp60 chaperone activity. It can impede the chaperone function of both wild-type proteins and the C237A and C447A mutant proteins. ETB binds to Hsp60 at Cys442, and the C442A mutant demonstrates resistance to ETB inhibition.

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).

Aprocitentan-D4 is a deuterium-labeled Aprocitentan. Aprocitentan (T7817) is a major and pharmacologically active metabolite of Macitentan. Aprocitentan (T7817) 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 the Endothelin receptor type B, inhibiting the binding of Endothelin-1 to the receptor at nanomolar concentrations (reported IC₅₀ ≈ 1.2 nM).

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).

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.

Macitentan-D4 is a deuterated substitute for Macitentan (T2561) 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.

Endothelin 1 (swine, human) is a potent endogenous vasoconstrictor peptide released primarily by endothelial cells and acting through ETA and ETB receptors. Endothelin 1 (swine, human) mediates vascular smooth-muscle contraction, promotes fibrosis, stimulates reactive oxygen species production, and induces pro-inflammatory signaling, making it central to studies of vascular dysfunction, hypertension, and oxidative stress–associated pathology.

Anti-ETBR Antibody (DEDN6526A Naked Antibody) is a highly specific monoclonal antibody targeting the endothelin B receptor (ETBR) and serves as the antibody for the ADC molecule DEDN6526A. DEDN6526A (RG-7636) is a humanized ETBR-targeting antibody-drug conjugate developed for melanoma research.

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.

Nolavetbart is a monoclonal antibody of the Human IgG2κ type targeting CanlupfamIL31RA. The isotype control product for Nolavetbart is Human IgG2kappa, Isotype Control.

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.

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 (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.

Ro 46-2005 is a synthetic non-peptide endothelin receptor antagonist, inhibits the specific binding of 125I-ET-1 to human vascular smooth muscle cells (ETA receptor, IC50: 220 nM).

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.
