BQ-3020 is a linear endothelin (ET) analog that is highly selective for ETB receptors. It displaces [125I] ET-1 binding to ETB receptors in porcine cerebellar membranes with an IC50 value of 0.2 nM [1].
ET-1, a 21-amino acid peptide, is one of known isoforms of endothelin (ET-1, ET-2, ET-3), it has strong vasoconstrictor and mitogenic activity. ETB receptor is one of endothelin receptors (i.e. ETA and ETB). ETB receptor has nearly the same affinity for all endothelin isoforms [2].
BQ-3020 displaced [125I] ET-1 binding to ETB receptors in porcine cerebellar membranes at a concentration 4,700 times lower than that to ETA receptors (selective to ET-1) on aortic vascular smooth muscle cells (IC50: 940 nM) [1].
In eight healthy men aged from 20-28 years, the local response of Sarafotoxin S6c (SFTX6c) (5 pmol/min) or BQ-3020 (50 pmol/min) to intra-arterial or intravenous infusion was assessed. Comparing these studies, there was no significant difference between baseline measurements. All the effects were just in the infused arm. Following intra-arterial infusion, both SFTX6c and BQ-3020 produced vasoconstriction indicated by the reduction in forearm blood flow (-25±7% and -27±7%, respectively). Following intravenous infusion, both SFTX6c and BQ-3020 produced a vein diameter reduction (-30±8% and -16±7%, respectively) [3].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
