Application
CE3F4 has been used as a selective exchange protein directly activated by cAMP isoform 1 (Epac1) inhibitor in cell proliferation assay to study the influence of Epac type I on cell proliferation of C6 cells (a model of glioma).
Biochem/physiol Actions
CE3F4 is a tetrahydroquinoline derivative that blocks agonist-stimulated Epac1 (exchange protein directly activated by cAMP isoform 1) guanine nucleotide exchange activity toward its effector Rap1 (IC50 = 23 μM; Epac agonist = 2 μM 8-CPT-2′-O-Me-cAMP) by targeting agonist-bound Epac1 in an agonist-uncompetitive manner without affecting the GDP exchange on Rap1, Rap1-Epac1 interaction, or PKA type I/II activity (CβRIβ & CαRIIβ). CE3F4 (20 μM) effectively inhbits cellular Rap1 activation upon 10 μM Sp-8-pCPT-2′-O-Me-cAMPS (Epac1-transfected HEK293 and rat neonatal cardiac myocytes) or 10 μM β-adrenergic receptor agonist isoprenaline stimulation (β1AR & Epac1 dually transfected HEK293). The isolated CE3F4 R enantiomer is reported to display 10-fold Epac1 selectivity over Epac2, and is 10-times more potent than the CE3F S enantiomer against Epac1.
Epac1 is a downstream effector of the cyclic adenosine monophosphate (cAMP) pathway.

Isoform 1 and isoform 2 of exchange protein directly activated by cAMP (Epac1 and Epac2) contribute to cAMP signaling in numerous cellular processes. Their guanine-nucleotide exchange factor (GEF) activity toward the small GTP-binding protein Rap1 is stimulated by the agonist

The signaling molecule cAMP primarily mediates its effects by activating PKA and/or exchange protein activated by cAMP (Epac). Epac has been implicated in many responses in cells, but its precise roles have been difficult to define in the absence of

Supressed levels of intracellular cAMP have been associated with malignancy. Thus, elevating cAMP through activation of adenylyl cyclase (AC) or by inhibition of phosphodiesterase (PDE) may be therapeutically beneficial. Here, we demonstrate that elevated cAMP levels suppress growth in C6
