BQ-123 SODIUM SALT Chemical Properties,Usage,Production

Uses

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.

Definition

ChEBI: BQ 123 is a cyclic peptide.

Biological Activity

bq-123 is a potent and selective antagonist of eta endothelin receptor with ki values of 1.4 and 1500 nm for eta and etb receptors, respectively.endothelin receptor is a g protein-coupled receptor. eta receptor increases intracellular-free ca2+. also, activation of eta receptor increases vasoconstriction and blood pressure.bq-123 is a selective eta receptor antagonist. in the eta-expressing cells, bq123 (10-6 m) inhibited endothelin-1 (et-1) (10-6 m)-induced [ca2+]i increase by 95% [1]. in rat vascular smooth muscle cells (vsmc), bq-123 inhibited et-1 receptor binding, cellular contraction, [ca2+ ]i mobilization, [3h]thymidine incorporation, map kinase activation and mtt reduction induced by et-1. however, bq-123 didn’t inhibit angiotensin ii (ang ii)- and arginine vasopressin (avp)-induced increases in map kinase activity and [ca2+]i mobilization [2].in spontaneously hypertensive rats (shr), renin hypertensive rats and normotensive rats, bq-123 (16 nm/kg/min) reduced mean arterial pressure in a dose-dependent way in shr. also, bq-123 lowered blood pressure in both renin hypertensive rats and normotensive rats [3]. in a kidney transplantation rat model with reperfusion injury, bq-123 prevented reperfusion injury and inhibited the synthesis and release of et-1,2 [4].
