thio-evodiamine (66c) showed excellent in vitro and in vivo antitumor efficacy with good tolerability and low toxicity. Antitumor mechanism and target profiling studies indicate that compound 66c is the first-in-class triple topoisomerase I/topoisomerase II/tubulin inhibitor. Overall, this study provided an effective strategy for natural product-based drug discovery.

dual unsaturated pendants, i.e. pyrrole and alkenic moieties, initiates a complexity building photoinduced cascade of an unprecedented formal [4+2+2+2] topology, resulting in the formation of four σ-bonds and setting six new stereogenic centers in a single photochemical step with up to 220 mcbit complexity increases.
