GS-6201 (CVT-6883) is a selective adenosine A2B receptor antagonist. GS-6201 displays high affinity and selectivity for the human adenosine A2B receptors (Ki=22 nM). GS-6201 reduces caspase-1 activity in the heart, and attenuates cardiac remodeling after acute myocardial infarction (AMI) in the mouse. GS-62013 attenuates the airway reactivity induced by NECA, AMP, or allergen in sensitized mice.

Description

GS-6201 (CVT-6883) is a selective adenosine A2B receptor antagonist. GS-6201 displays high affinity and selectivity for the human adenosine A2B receptors (Ki=22 nM)[1]. GS-6201 reduces caspase-1 activity in the heart, and attenuates cardiac remodeling after acute myocardial infarction (AMI) in the mouse[2]. GS-62013 attenuates the airway reactivity induced by NECA, AMP, or allergen in sensitized mice[3].

IC50 & Target

Ki: 22 nM (human A2B receptors), 1070 nM (human A3 receptors), 1940 nM (human A1 receptors), 3280 nM (human A2A receptors)[1]
In Vivo

GS-6201 (CVT-6883) (4 mg/kg; i.p.; every 12 h for 14 days) significantly reduces IL-6, TNF-α, E-selectin, ICAM-1, and VCAM plasma levels[2].
GS-6201 (4 mg/kg; i.p.; every 12 h for 14 days) leads to a significant attenuation of left and right ventricular enlargement and dysfunction at 7 days, which was maintained at 14 days and also at 28 days[2].
GS-6201 (2 mg/kg; p.o.) treatment shows the Cmax, dAUC and t1/2 are 1110 ng/mL, 6500 ng h/mL, and 4.25 hours, respectively[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2 mg/mL (4.48 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2 mg/mL (4.48 mM); Clear solution

    This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
