FLLL31 selectively binds to Janus kinase 2 and the STAT3 Src homology-2 (SH2) domain, effective inhibitors of STAT3 phosphorylation. STAT3 plays a critical role in early embryogenesis, but is largely dispensable in normal adult cells and tissues. On the other hand the JAK2/STAT3 signaling pathway is persistently activated in great number of human solid and blood cancers. Such activation is commonly associated with a worse prognosis. FLLL31 is a curcumin derivative locked in diketone-tautomeric form, which supposedly improves binding to SH2 domain. The compound inhibits JAK2 kinase activity and prevents STAT3 phosphorylation. FLLK31 is a potent and selective inhibitor of the STAT3 signaling pathway.
