Apexbio Technology LLC BQ-788 SODIUM SALT 1MG
Supplier: Apexbio Technology LLC B32781
BQ-788 sodium salt (CAS 156161-89-6) is a selective antagonist targeting endothelin B (ETB) receptors In vitro studies demonstrate that BQ-788 inhibits ET-1 binding to human ETB receptors with an IC50 of approximately 1 2 nM displaying significantly lower affinity for ETA receptors (IC50 1300 nM) Competitive binding assays also confirm potent ETB receptor antagonism in porcine cerebellar membranes and human hGH cells (IC50 0 9-1 2 nM) BQ-788 exhibits minimal activity towards other peptide hormone receptors tested at concentrations up to 10 M Its notable selectivity and potency for ETB receptors make BQ-788 valuable for investigating ET receptor-mediated physiological processes such as bronchoconstriction
