  DNA Cleavage Potency, Cytotoxicity, and Mechanism of Action of a Novel Class of Enediyne Prodrugs

  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.

  Novel C3-substituted cyclodeca-1,5-diynes can be prepared through novel synthetic procedures using starting (E)-C3-substituted-4-(aryl- or heteroarylmethylidene)cyclodeca-1,5-diynes reagents. Both the C3-substituted cyclodeca-1,5-diyn-3-enes and the starting reagents have improved thermal stability compared to unsubstituted counterparts.

  日期：2001.6

  A general and facile synthesis of the 3-substituted 10-membered ring enediynes 18-22 from the aldehydes 8 and 15 has been established by utilizing the intramolecular Nozaki-Hiyama-Kishi reaction and the lwanthanide(III)-catalyzed rearrangement of allylic alkoxyacetates as the key steps. This work provides ready access to the (E)-3-acyloxy-4-(arylmethylidene)cyclodeca-1,5-diynes, which can be converted into the bioactive enediynes under physiological conditions.
