Biological Activity

Description

Regadenoson (CVT-3146, Lexiscan) is a selective A2A adenosine receptor agonist with coronary vasodilating activity.

Targets

A2AR ^[1]

290 nM(Ki)

In vitro
In vitro	Regadenoson has a relatively low binding affinity (hA2A Ki=290 nM) for human A2A receptors and greater than 30-fold selectivity versus the A2B and A3AR subtypes and 13-fold over the A1AR. Regadenoson behaves as a weak partial agonist causing cAMP accumulation in PC12 cells but as a full and potent agonist causing coronary vasodilation^[1].

In Vivo
In vivo	In a dog model, intravenous bolus injection of regadenoson causes a dose-dependent increase in myocardial blood flow and a dose-dependant decrease in coronary vascular resistance. In a rat heart model, regadenoson was shown to have a dose-dependent increase in heart rate and a decrease in mean arterial pressure at the higher doses. Regadenoson also caused more than a 2-fold increase in serum norepinephrine and epinephrine. For clinical data, Regadenoson has a volume of distribution of 11.5 L and 78.7 L (at steady-state), and an estimated clearance of 37.8 L/h. It is renally excreted (58% of total elimination) with a terminal half-life of 33 to 108 min^[2].

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 ddH₂O, 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.
