Abstract: Resistance phenomena during chemotherapy of tumor has been severely hampering the applications of chemotherapeutics. Due to advantage of drug repurposing, discovery of new chemosensitizers based on approved drugs is an effect strategy to find new candidates. Herein, we found antidepressant drug - sertraline, could sensitize drug-resistant gastric cancer cell (SGC-7901/DDP) with the IC value of 18.73 μM. To understand the structure-activity relationship and improve the activity, 30 derivatives were synthesized and evaluated. The IC value of the best compound was improved to 5.2 μM. Moreover, we found apoptosis induction and cell cycle arrest was the reason for the cell death of the drug-resistant cells after treatment of sertraline and derivatives, and PI3K/Akt/mTOR pathway was involved.
