Drug repurposing: Discovery of troxipide analogs as potent antitumor agents.

ABSTRACT: 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 μM, 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 sig
