Embodiments of the invention are directed to compounds that inhibit an activity of EP AC proteins and methods of using the same. The inventors have developed a sensitive and robust high throughput screening (HTS) assay for the purpose of identifying EPAC specific inhibitors (Tsalkova et al. (2012) PLOS ONE 7 (1):e30441).

EPAC1 and EPAC2, two isoforms of exchange proteins directly activated by cAMP (EPAC), respond to the second messenger cAMP and regulate a wide variety of intracellular processes under physiological and pathophysiological circumstances. Herein, we report the chemical design, synthesis, and pharmacological characterization of three different scaffolds (diarylsulfones, N,N-diarylamines, and arylsulfonamides) as highly potent and selective antagonists of EPAC2. Several selective EPAC2 antagonists have been identified including 20i (HJC0350), which has an apparent IC50 of 0.3 mu M for competing with 8-NBD-cAMP binding of EPAC2 and is about 133-fold more potent than cAMP. Compounds 1 (ESI-05), 14c (HJC0338), and 20i, selected from each series, have exhibited no inhibition of EPAC1-mediated Rap1-GDP exchange activity at 25 mu M, indicating that they are EPAC2-specific antagonists. Moreover, live-cell imaging studies using EPAC1, EPAC2, or PICA FRET sensor also demonstrate that 20i functions as an EPAC2 specific antagonist.
