DM243 is an EPAC1 activator and STAT3 modulator known for its ability to increase GTP-bound Rap1 levels specifically in EPAC1-expressing cells, while exhibiting no effects on EPAC2 or PKA. This compound effectively reduces IL-6/IL-6Rα-induced STAT3 phosphorylation in endothelial cells and suppresses TGF-β1-mediated fibroblast-to-myofibroblast transition, leading to decreased levels of α-smooth muscle actin and Collagen I in lung fibroblasts. Additionally, DM243 demonstrates minimal cytotoxicity in normal human lung fibroblasts, making it a valuable tool for studies related to fibrosis and inflammation.
