N2 - Drug repurposing plays a vital role in the discovery of undescribed bioactivities in clinical drugs. Based on drug repurposing strategy, we for the first time reported a novel series of troxipide analogs and then evaluated their antiproliferative activity against MCF-7, PC3, MGC-803, and PC9 cancer cell lines and WPMY-1, most of which showed obvious selectivity toward PC-3 over the other three cancer cell lines and WPMY-1. Compound 5q, especially, could effectively inhibit PC3 with an IC50 value of 0.91 mu M, which exhibited around 53-fold selectivity toward WPMY-1. Data indicated that 5q effectively inhibited the colony formation, suppressed the cell migration, and induced G1/S phase arrest in PC3 cells. Also, compound 5q induced cell apoptosis by activating the two apoptotic signaling pathways in PC3 cells: death receptor-mediated extrinsic pathway and mitochondria-mediated intrinsic pathway. Compound 5q up-regulated the expression of both pro-apoptotic Bax and P53, while down-regulated anti-apoptotic Bcl-2 expression. Besides, compound 5q significantly increased the expression of cleaved caspase 3/9 and cleaved PARP. Therefore, the successful discovery of compound 5q may further validate the feasibility of this theory, which will encourage researchers to reveal undescribed bioactivities in traditional drugs.
