| Description | OPC-28326 is a specific an α2-adrenergic receptor antagonist and acts as a peripheral vasodilator. OPC-28326 inhibits α2A-, α2B- and α2C-adrenoceptors with Ki of 2040, 285, and 55 nM, respectively. |
| Targets&IC50 | α2A-adrenoceptor:2040 nM (ki), α2C-adrenoceptor:55 nM (ki), α2B-adrenoceptor:285 nM (ki) |
| In vitro | OPC-28326 augments microvessel growth and improves endothelial tube formation. OPC-28326 dose-dependently induces phosphorylation of eNOS and Akt without affecting total amounts of eNOS and Akt in HAECs[1]. |
| In vivo | OPC-28326 improves blood flow recovery in murine hindlimb ischemia and increases the number of capillaries in the ischemic leg[1]. In rats, intravenous administration of OPC-28326 (3 - 30 mg/kg) and yohimbine (0.3 - 3 mg/kg) results in a dose-dependent rightward shift in the pressor dose-response curve induced by B-HT 920 without affecting the mydriasis[2]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
