生物活性

Tetramethylcurcumin (FLLL31), derived from curcumin, specifically suppresses the phosphorylation of STAT3 by binding selectively to Janus kinase 2 and the STAT3 Src homology-2 domain. Tetramethylcurcumin exhibits anti-inflammatory and anti-cancer effects[1][2].

IC50 & Target[1]

STAT3

 

体外研究
(In Vitro)

Tetramethylcurcumin (FLLL31; 2.5 and 5 µM; for 24 hours) downregulats STAT3 phosphorylation and DNA-binding activity in MDA-MB-231 breast and PANC-1 pancreatic cancer cells[1].
Tetramethylcurcumin inhibits cell viability, cell invasion. Tetramethylcurcumin is a effective inhibitor of STAT3 phosphorylation, DNA-binding activity, and transactivation in vitro, leading to the impediment of multiple oncogenic processes and the induction of apoptosis in pancreatic and breast cancer cell lines[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
