BQ-3020 TFA

BQ-3020 (TFA) is a selective ETB receptor agonist that obstructs [125I]ET-1 binding to the ETB receptor in the cerebellum, exhibiting an IC50 of 0.2 nM, and induces vasoconstriction [1].

BQ-3020 (TFA) is a selective ETB receptor agonist that inhibits [125I] et-1 binding to the ETB receptor in the cerebellum with a 0.2nm IC50, causing vasoconstriction.

BQ-3020 ammonium, a selective endothelin receptor (ET B receptor) agonist, demonstrates inhibition of [125 I] ET-1 binding to ET B receptors with an IC50 of 0.2 nM and induces vasoconstriction in rabbit pulmonary arteries. Additionally, it promotes relaxation of the pig urinary bladder neck, rendering it useful for research into cardiovascular diseases [1] [2].

BQ-123 TFA, a potent and selective endothelin A (ETA) receptor antagonist, demonstrates an IC50 of 7.3 nM and a Ki of 25 nM. It effectively inhibits endothelin-1-induced proliferation of human pulmonary artery smooth muscle cells and reduces blood pressure in various rat hypertension models [1] [2] [3].
