FLLL31

Tetramethylcurcumin (FLLL31; 2.5 and 5 μM; for 24 hours) downregulas STAT3 phosphorylation and DNA-binding activity in MDA-MB-231 breast and PANC-1 pancreatic cancer cells.
Tetramethylcurcumin inhibits cell viability , cell invasion. Tetramethylcurcumin is an 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.
