  Synthesis and DNA cleavage reaction characteristics of enediyne prodrugs activated via an allylic rearrangement by base or UV irradiation

  摘要：

  A number of enediyne prodrugs 1-5 possessing in (E)-3-Ilydi-oxy-4-(2'-hydroxy-1'-phenylethylidene)cyclodeca-1,5-diyne scaffold have been synthesized via the Sonogashira Coupling and an intramolecular Nozaki-Hiyama-Kishi reaction as the key steps. Upon incubation with enediyne prodrugs 4 and 5 possessing a free hydroxymethyl group oil the exocyclic double bond, circular supercoiled DNA (Form 1) underwent single strand cleavage into Circular relaxed DNA (Form 11) in buffer solution at pH 8.5, while the silylated analogs 1-3 showed very weak DNA cleavage activity. Alternatively, the silylated analogs 1-3 Could be activated by UV irradiation via a photochemical alkene isomerization followed by an allylic rearrangement to form the putative epoxy enediyne, resulting in efficient DNA cleavage similar to the level observed with the prodrugs 4 and 5.
