Amino Acid Sequence

cyclo-Asp-Pro-Val-Leu-Trp

Applicazioni

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.

Azioni biochim/fisiol

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

1. Endothelin-1 binds almost irreversibly to its receptors and causes prolonged vasoconstrictions. Here we have studied the reversal of established responses to ET-1 in vivo and in vitro by BQ-123, an ETA receptor-selective antagonist, and/or PD 145065, an ETA/ETB receptor

The present study was designed to determine whether an endothelinA (ETA)-receptor antagonist BQ-123 (cyclo[Dtrp, Dasp, pro-D-Val-Leu]) or an ET-converting enzyme inhibitor phosphoramidon may prevent development of cerebral vasospasm after subarachnoid hemorrhage (SAH). A "double hemorrhage" canine model of the disease

Among organic anion transporting polypeptide (Oatp) family transporters expressed in the rodent liver, such as Oatp1a1, Oatp1a4, Oatp1b2, and Oatp2b1, Oatp1a4 has a unique character to recognize neutral cardiac glycosides as a substrate in addition to organic anions. The relative
