Description

Amino Acid Sequence

cyclo-Asp-Pro-Val-Leu-Trp

Application

BQ-123 has been used as a selective endothelin-A receptor antagonist to study its effects on tumor necrosis factor α (TNFα)-induced human airway smooth muscle cells (HASMCs) proliferation. It is also used as endothelin-A receptor antagonist to study its effects on TNFα-induced granulocyte–macrophage colony-stimulating factor (GM-CSF) expression.

Biochem/physiol Actions

BQ-123 is an endothelin(Et) receptor antagonist and is exquisite for endothelin A (ETA) receptor. It is a cyclic pentapeptide.

Selective ET_A endothelin receptor antagonist.
