Biological Activity
IC50: 0.43 μM (EPAC2)[1]
ESI-05 (0.01 μM -1 nM) inhibits cAMP-mediated EPAC2 GEF activity with IC50 of 0.43 μM, but completely ineffective in suppressing EPAC1 GEF activity[1].
?
ESI-05 (1, 5, 10, and 25 μM; 5 min) selectively modulates EPAC2 activation in living cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:HEK293 cells
-
Concentration:1, 5, 10, and 25 μM
-
Incubation Time:5 min
-
Result:Led to a dose-dependent reduction of the EPAC-selective cAMP analog (007-AM) induced Rap1 activation.

Animal Model:Intracranial hemorrhage (ICH) model[2]
-
Dosage:2, 4, and 8 mg/kg
-
Administration:
-
Result:Decreased the apoptosis rate of nerve cells in the cortex accompanied by a corresponding decrease in the protein expression of phosphorylated p38, Bcl-2like protein 11 (BIM), and caspase-3.

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.
Please enter the basic information of animal experiments:
