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.

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.

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).

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.

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.

The S-enantiomer of BET-BAY 002, referred to as BET-BAY 002 S enantiomer, is a potent inhibitor of BET (Bromodomain and Extra-Terminal motif proteins).

BET-BAY 002 is an effective BET bromodomain inhibitor demonstrating efficacy in vivo and in vitro against multiple myeloma and leukaemia models.

PROTAC BET-binding moiety 1 is a crucial intermediate used in synthesizing high-affinity BET inhibitors.

PROTAC BET-binding moiety 2 is an inhibitor of the BET bromodomain.

PROTACSMARCA2 degrader-6-Linker is a PROTAC linker that facilitates the connection between an E3 ligase ligand and a SMARCA2 ligand to form PROTACSMARCA2 degrader-6.

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.

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).

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.

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).

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.

SB-209670 is a selective endothelin receptor antagonist that inhibits the activity of ET(B) receptors in rat vascular endothelium and vascular smooth muscle.

AMPA receptor modulator-2 (Example 134) is an AMPA receptor modulator with a pIC50 of 10.1 for TARPγ2 dependent AMPA receptor[1]. pIC50 = -lgIC50. [1]. BERRY CYNTHIA G B (US), et al. AZABENZIMIDAZOLES AND THEIR USE AS AMPA RECEPTOR MODULATORS. Patent. WO2016176460.

Cyanosafracin B is a starting material for the synthesis of Phthalascidin Pt-650 and Ecteinascidin ET-743.

COR659 is a GABAB positive allosteric modulator (PAM) . COR659 suppresses alcohol and chocolate self-administration in rats[1]. COR659 apparently exerts its effects via a composite mechanism, including positive allosteric modulation of the GABAB receptor and an action at the cannabinoid CB1 receptor[3]. COR659 (0, 2.5, 5 and 10 mg/kg) treatment is completely ineffective on lever-responding (FR10) for regular food pellets in food-deprived Wistar rats[1].COR659 is able to suppress lever-responding for a sucrose solution in sP rats and a chocolate solution in Wistar rats[2]. Animal Model: Male sP and Wistar rats[1]. [1]. Paola Maccioni, et al.
