Biochem/physiol Actions

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.

Several compounds extracted from spices and herbs exhibit antiviral effects in vitro, suggesting potential pharmacological uses. Curcumin, a component of turmeric, has been used as a food additive and herbal supplement due to its potential medicinal properties. Previously, curcumin exhibited antiviral

Pattern recognition receptors (PRR) promote inflammation but also its resolution. We demonstrated that a specific PRR-formyl peptide receptor 1 (FPR1)-sustains an inflammation resolution response with anti-angiogenic and antitumor potential in gastric cancer. Since toll-like receptor 7 (TLR7) is crucial in
