Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide, synthesizing and screening of novel anti-cancer drugs provides an alternative therapeutic strategy for renewal of the chemotherapy regimens against lung cancer. To this end, several compounds were synthesized based on the modification of the original myricetin, and their anti-tumor activity against the human non-small cell lung cancer (NSCLC) A549 cells were measured. Among the myricetin derivatives, S4-10 has displayed the highest antitumor efficacy in dose-dependent manner. The proliferation of A549 cells were significantly attenuated by given 6 µM of S4-10 both in vitro and in vivo. Further, the treatment of S4-10 also results in the inhibition of cell migration and invasiveness and the induction of cell apoptosis and G2 cycle arrest of A549 cells. Moreover, we found that S4-10 inhibits the progression of A549 cells through the sterol biosynthetic-cell apoptosis axis. These findings shed the light of developing S4-10 as a promising treatment agent for NSCLC.
