IC50: 8.4 μM (EPAC2)[1]
EPAC1[1]
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].
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].

5-Cyano-6-oxo-1,6-dihydro-pyrimidines as potent antagonists targeting exchange proteins directly activated by cAMP
Bioorg Med Chem Lett 2012 Jun 15;22(12):4038-43.PMID:22607683DOI:PMC3362663
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. To explore the structural determinants for Epac antagonist properties of high throughput screening (HTS) hit ESI-08, pyrimidine 1, a series of 5-cyano-6-oxo-1,6-dihydro-pyrimidine analogues have been synthesized and evaluated for their activities for Epac inhibition. Structure-activity relationship (SAR) analysis led to the identification of three more potent Epac antagonists (6b, 6g, and 6h). These inhibitors may serve as valuable pharmacological probes for further elucidation of the physiological functions and mechanisms of Epac regulation. Our SAR results and molecular docking studies have also revealed that further optimization of the moieties at the C-6 position of pyrimidine scaffold may allow us to discover more potent Epac-specific antagonists.
