Product Introduction

Bioactivity
Description
BQ-788 is a selective and potent ETB receptor antagonist with potential hypertensive activity.BQ-788 inhibits ET-1 binding to ETB receptors and inhibits exogenous ET-1-induced elevation of coronary artery perfusion pressure.
Targets&IC50
ETB:1.2 nM, ETA:1300 nM (Human SK-N-MC cells)
In vitro
BQ-788 potently and competitively inhibits the binding of (125I-labeled ET-1) to ETB receptors in human Girardi heart cells (hGH) with an IC50 of 1.2 nM, but poorly inhibits the binding to ETA receptors in human neuroblastoma cells (SK-N-MC) with an IC50 of 1300 nM. Up to 10 μM, BQ-788 shows no agonistic activity and competitively inhibits vasoconstriction induced by an ETB-selective agonist (pA2, 8.4). Additionally, BQ-788 inhibits several bioactivities of ET-1, including bronchoconstriction, cell proliferation, and clearance of perfused ET-1[1].
In vivo
In conscious rats, BQ-788 (3 mg/kg/h, i.v.) completely inhibits ETB receptor-mediated depressor responses induced by a pharmacological dose of ET-1 or sarafotoxin6c (0.5 nmol/kg, i.v.), but not pressor responses. Additionally, BQ-788 markedly increases the plasma concentration of ET-1, considered an index of potential ETB receptor blockade in vivo. In Dahl salt-sensitive hypertensive (DS) rats, BQ-788 (3 mg/kg/h, i.v.) raises blood pressure by about 20 mm Hg. It is reported that BQ-788 also inhibits ET-1-induced bronchoconstriction, tumor growth, and lipopolysaccharide-induced organ failure[1]. BQ 788 (3 mg/kg) results in an eightfold leftward shift in the ET-1 dose-response curve, suggesting significant involvement of ETB dilator receptors[2]. In mice treated with 30 nmol BQ-788 by intraplantar administration, there is a reduction in mechanical hyperalgesia (47% and 42%), thermal hyperalgesia (68% and 76%), oedema (50% and 30%), myeloperoxidase activity (64% and 32%), and overt-pain like behaviors. Additionally, intraplantar treatment with clazosentan or BQ-788 decreases spinal (45% and 41%) and peripheral (47% and 47%) superoxide anion production as well as spinal (47% and 47%) and peripheral (33% and 54%) lipid peroxidation, respectively[3].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
