8-CPT-2Me-cAMP, sodium salt is a selective agonist of EPAC .
Cyclic AMP guanine nucleotide exchange factors (EPACs) are intracellular sensors for cAMP and function as nucleotide exchange factors for the Ras GTPase homologues Rap1 and Rap2 .
8-CPT-2Me-cAMP, sodium salt is a selective EPAC agonist. 8-CPT-2Me-cAMP increased Rap1 activation by EPAC1. Meantime, light chain 2 (LC2) of the microtubule-associated protein MAP1A increased this response. In LC2- and EPAC1-transfected cells, 8-CPT-2Me-cAMP increased cell adhesion to laminin . In Jurkat Tcells, 8-CPT-2Me-cAMP (100 μM) activated Rap1, which was not affected by H-89, a PKA inhibitor . In 1-LN prostate cancer cells, 8-CPT-2Me-cAMP increased Epac1, p-AktS473 and p-AktT308 in a dose-dependent way. 8-CPT-2Me-cAMP increased p-AktS473 and AktS473 kinase activity by two-three fold. Also, 8-CPT-2Me-cAMP activated mTORC1 and mTORC2 .
In human prostate cancer cells, 8-CPT-2Me-cAMP increased the levels of p-cPLA2S505, COX-2 and PGE2. However, COX-2, EP4 or mTOR inhibitors inhibited this effect and reduced protein and DNA synthesis induced by Epac1. These results suggested Epac1 was a pro-inflammatory modulator and promoted cell proliferation .
