Beschreibung

General description

A cell-permeable compound that targets cAMP-binding domain of EPAC/cAMP-GEF and inhibits cAMP-dependent EPAC GEF activity (IC₅₀ = 1.4 and 3.2 µM, respectively, against EPAC2 and EPAC1).

A cell-permeable, propionitrile compound that targets the CBD (cAMP-binding domain) of EPAC/cAMP-GEF with 4-fold higher affinity than cAMP (IC₅₀ = 10 vs. 39 µM, respectively, against 8-NBD-cAMP in competition EPAC2 binding assay) and selectively inhibits cAMP-dependent EPAC GEF activity (IC₅₀ = 1.4 and 3.2 µM, respectively, against EPAC2 and EPAC1; [cAMP] = 25 µM) with much reduced potency toward cAMP-dependent PKA activity (10% and 20% inhibition at 100 µM, respectively, against 100 µM cAMP-stimulated Type Iα and IIβ PKA activity). Shown to block both basal and 8-CPT-2′-O-Me-cAMP prodrug 007-AM-stimulated Akt thr308/Ser473 phosphorylations in serum-starved human pancreatic cancer AsPC-1 (%thr308/%Ser473 of basal phosphorylation = 200%/185%, 85%/65%, and <10%/<10%, respectively, with 0, 1, 10 µM ESI-09; [007-AM] = 10 µM) and rat pancreatic β-cell INS-1 without affecting EGF-stimulated Akt phosphorylations, resulting in effective inhibition of EPAC-mediated insulin secretion from INS-1 cells (by 57% and 100%, respectively, at 5 and 10 µM; [007-AM] = 10 µM) and pancreatic cancer cell invasion (~60% inhibition at 5 µM using AsPC-1 and PANC-1 cells).
