hydroxyl group at C-5 of PL might interact with STAT3 in the form of hydrogen bonds, which is conducive to the binding of this kind structures with STAT3. Among the target compounds, 7a displayed the most potent inhibition against cancer cells and weaker cytotoxicity on normal cells than PL. The western bolting analysis showed that 7a could suppress the phosphorylation of STAT3 as well as the downstream genes
