Description

General description

A highly selective ET_A receptor antagonist (IC₅₀ = 20 nM) that attenuates ET-induced reduction in cardiac output. Also inhibits ET-1- and ET-3-induced activation of adenylate cyclase (IC₅₀ = 28.2 nM). BQ-610 is 30-fold more potent than BQ-123 (Cat. No. 05-23-3831) in porcine aortic smooth muscle membrane assay.

A highly selective endothelin A (ET_A) receptor antagonist (IC₅₀ = 20 nM) that attenuates ET-induced reduction in cardiac output. Inhibits ET-1 induced mitogenesis in airway smooth muscle cells in a concentration-dependent manner (IC₅₀ = 20 nM). Also inhibits ET-1 and ET-3 induced activation of adenylate cyclase (IC₅₀ = 28.2 nM). Has been shown to prevent endothelin-induced vasoconstriction. BQ-610 is 30-fold more potent than BQ-123 (Cat. No. 05-23-3831) in a porcine aortic smooth muscle assay.
