DM245
DM245 is an EPAC1 activator and STAT3 phosphorylation inhibitor with a target pIC50 of 4.801. DM245 activates EPAC1 to increase Rap1-GTP levels, with no activation of EPAC2 or PKA. DM245 reduces IL-6/IL-6Rα-evoked STAT3 phosphorylation in endothelial cells. DM245 suppresses TGF-β1-induced fibroblast-to-myofibroblast transition, reducing αSMA and Collagen I levels. DM245 exhibits minimal cytotoxicity in normal human lung fibroblasts, with negligible loss of intact nuclei after 72 h exposure.

p-STAT3 |
DM245 binds to the EPAC1 CNBD with a pIC50 of 4.80, indicating micromolar affinity for the EPAC1 cyclic nucleotide-binding domain[1].
DM245 (100 μM) significantly activates the EPAC1-Rap1 signaling pathway in EPAC1-transfected U2OS cells[1].
DM245 (1 μM) significantly attenuates IL-6/IL-6Rα-induced STAT3 phosphorylation in HUVECs[1].
DM245 (logarithmic concentration range; 1 h pretreatment, 72 h TGF-β1 stimulation) inhibits TGF-β1-induced fibroblast-to-myofibroblast transition in normal human lung fibroblasts, with midmicromolar potency for both αSMA (pIC50 = 4.58) and Collagen I (pIC50 = 4.34) suppression[1].
DM245 (logarithmic concentration range; 72 h) exhibits minimal cytotoxicity in normal human lung fibroblasts at concentrations effective for suppressing TGF-β1-induced fibroblast-to-myofibroblast transition[1].
