  3. ESI-08

ESI-08 is a potent and selective EPAC antagonist, which can completely inhibit both EPAC1 and EPAC2 (IC50 of 8.4 μM) activity. ESI-08 selectively blocks cAMP-induced EPAC activation, but does not inhibit cAMP-mediated PKA activation.

Description

ESI-08 is a potent and selective EPAC antagonist, which can completely inhibit both EPAC1 and EPAC2 (IC50 of 8.4 μM) activity. ESI-08 selectively blocks cAMP-induced EPAC activation, but does not inhibit cAMP-mediated PKA activation[1].

IC50 & Target

IC50: 8.4 μM (EPAC2)[1]
EPAC1[1]

In Vitro

Exchange proteins directly activated by cAMP (EPAC) are a family of guanine nucleotide exchange factors that regulate a wide variety of intracellular processes in response to second messenger cAMP. ESI-08 at 25 μM has been found not to alter cAMP-induced type I and II PKA holoenzymes activation while H89, a selective PKA inhibitor, blocked the type I or II PKA activities completely[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
