Deskripsi

A series of 1,4-naphthoquinone derivatives containing were synthesized as anti-cancer agents and the crystal structure of compound <b>5a</b> was confirmed by X-ray diffraction. In addition, the inhibitory activities against four cancer cell lines (HepG2, A549, K562, and PC-3) were tested, respectively, and compound <b>5i</b> showed significant cytotoxicity on the A549 cell line with the IC<sub>50</sub> of 6.15 μM. Surprisingly, in the following preliminary biological experiments, we found that compound <b>5i</b> induced autophagy by promoting the recycling of EGFR and signal transduction in the A549 cell, resulting in the activation of the EGFR signal pathway. The potential binding pattern between compound <b>5i</b> and EGFR tyrosine kinase (PDB ID: 1M17) was also identified by molecular docking. Our research paves the way for further studies and the development of novel and powerful anti-cancer drugs.
