Biological Activity

Description BQ-123 is a selective endothelin A receptor (ETA) antagonist with IC50 of 7.3 nM. Phase 2.
Targets
Endothelin A receptor [1]
(Cell-free assay)
7.3 nM
In vitro In porcine aortic vascular smooth muscle cells, BQ-123 selectively inhibits ETA-mediated contraction. [1] In rat vascular smooth muscle cells, BQ-123 inhibits endothelin-1-induced phosphoinositide breakdown and DNA synthesis. [2]
In vivo In rats, BQ-123 (1 mg/kg, i.v.) ameliorates myocardial ischemic-reperfusion injury. [3] In rats with pentylenetetrazole (PTZ)-induced tonic-clonic seizures, BQ-123 (3 mg/kg, i.v.) potently impedes the formation and spread of seizure. [4] In pregnant C57BL/6 mice, BQ-123 (6.7 mg/kg, i.p.) prevents LPS-induced preterm birth in mice via the induction of uterine and placental IL-10. [5]
