product name ESI-09


Description: ESI-09 is a specific exchange protein directly activated by cAMP (EPAC) inhibitor with IC50 of 3.2 μM and 1.4 μM for EPAC1 and EPAC2, respectively, it displays >100-fold selectivity over PKA. ESI-09 (25 µM) reduced EPAC1 and EPAC2 GEF activity to basal levels in the presence of 25 µM cAMP. In the presence of 25 µM cAMP, ESI-09 inhibited cAMP-mediated EPAC2 and EPAC1 GEF activity with IC50 values of 1.4 and 3.2 µM respectively and exhibited 100 times selectivity than PKA.

In Vitro

In vitro activity: ESI-09, a novel non-cyclic nucleotide EPAC antagonist, that is capable of specifically blocking intracellular EPAC-mediated Rap1 activation and Akt phosphorylation, as well as EPAC-mediated insulin secretion in pancreatic β cells. On the other hand, ESI-09 fails to suppress epidermal growth factor (EGF)-induced phosphorylation of Akt in AsPC1 cells. In pancreatic cancer cells, ESI-09 inhibits cells migration and invasion through decreasing 007-AM-induced cell adhesion dose-dependently. ESI-09 significantly reduces intracellular and total bacterial counts in human umbilical vein endothelial cells. ESI-09 effectively antagonizes Schwann cells (SC) differentiation induced by CPT-cAMP as well as the formation of myelin. In SC-neuron cultures, ESI-09 dramatically reduces the number of O1 positive and MBP positive SCs without compromising the health of the neurons or the SCs themselves.


Kinase Assay:


Cell Assay: In the pancreatic cancer cell line AsPC-1, ESI-09 inhibited Akt phosphorylation at T308 and S473 stimulated by 007-AM in a dose dependent way. In pancreatic endocrine β cells, ESI-09 inhibited the increase of insulin secretion stimulated by 007-AM in a dose dependent way. In pancreatic cancer cell lines AsPC-1 and PANC-1, ESI-09 significantly reduced cell migration through the inhibition of EPAC1.

In Vivo ESI-09 (10 mg/kg/d, i.p.), via pharmacological inhibition of EPAC1, protects WT C57BL/6 mice from fatal SFG rickettsiosis.
