  Oxidation of Adenosine and Inosine: The Chemistry of 8-Oxo-7,8-dihydropurines, Purine Iminoquinones, and Purine Quinones as Observed by Ultrafast Spectroscopy

  摘要：

  Oxidative damage to purine nucleic acid bases proceeds through quinoidal intermediates derived from their corresponding 8-oxo-7,8-dihydropurine bases. Oxidation studies of 8-oxo-7,8-dihyroadenosine and 8-oxo-7,8-dihydroinosine indicate that these quinoidal species can produce stable cross links with a wide variety of nucleophiles in the 2-positions of the purines. An azide precursor for the adenosine iminoquinone has been synthesized and applied in ultrafast transient absorption spectroscopic studies. Thus, the adenosine iminoquinone can be observed directly, and its susceptibility to nudeophilic attack with various nucleophiles as well as the stability of the resulting cross linked species have been evaluated Finally, these observations indicate that this azide might be a very useful photoaffurity labeling agent, because the reactive intermediate, adenosine iminoquinone, is such a good mimic for the universal purine base adenosine.

  A palladium-copper catalyst of homogeneous selective oxidation of thiols is proposed, combining a functional binuclear thiolate-bridged coordination compound of palladium (II) and a modifying thiolate complex of copper (I), having the general formula         [Pd2II(µ-SR)2(NH3)4] · CuIk(SR)m}     (I), where SR is the residue of a thiolate ligand, chosen from the group including a residue of glutathione and acetylcysteine, k = 2 to 14, m ≥ 3k. Also proposed are a catalytic combination, a pharmacological combination, a pharmaceutical composition, and a method of therapeutic action on a patient's organism based on the indicated catalyst.
