Endothelin Receptors

RO462005 is an endothelin receptor selective agonist.

IRL-2500 is a potent, selective ETBR antagonist. It shows some selectivity for ETB receptors (IC50 values are 1.3 and 94 nM for ETB and ETA receptors respectively).

Atrasentan is an experimental drug that is being studied for the treatment of various types of cancer, including non-small cell lung cancer. It is an endothelin receptor antagonist selective for subtype A (ETA).

BQ-788 sodium salt is a selective ETBR (Endothelin receptor B ) antagonist.

Endothelin-2, human, endogenous peptide found predominately in the kidney and intestine. Displays similar selectivity for ETA and ETB endothelin receptors.

BQ-123 is a selective endothelin A receptor (ETA) antagonist with IC50 of 7.3 nM. Phase 2.
