A series of enediyne prodrugs with (E)- or (Z)-3-hydroxy-4-(arylmethylidene)cyclodeca-1,5- diyne scaffolds have been synthesized via an intramolecular Nozaki-Hiyama-Kishi reaction as the key step. Cytotoxicity in micro molar range against P388 cancer cell line was observed for selected compounds and a structure-activity relationship is discussed.
