摘要：
The first structurally characterized example of a metal-metal bonded complex bridged by the DNA nucleobase adenine through the N1, N6 positions is reported. The new dirhenium compound, Re-2(O2CCH2CH3)(2)(9-EtA)(2)Cl-2 . CH3CH2O . C6H14, binds to adenine at the sites where thymine normally engages in Watson-Crick base-pairing. Such chemistry, if it occurs in vivo, could play a role in the carcinostatic activity of tetrapropionatodirhenium complexes that are known to inhibit DNA replication. (C) 1998 Elsevier Science S.A.
