摘要
We have discovered a novel class of (E)-3-acyloxy-4-(arylmethylidene)cyclodeca-1,5-diynes which exhibit promising enediyne-like DNA cleavage and cytotoxic activities. LC-MS analysis of the incubation mixture (pH 8.5, 37 degreesC) confirmed formation of 10-membered ring enediyne presumably via an allylic cation and suggested that the 1,4-benzenoid diradical might be one of the active species for DNA damage and cytotoxicity.
