Interaction of quinones with three pyrimidine bases: A laser flash photolysis study

The interaction between three different pyrimidine bases, uracil (U), cytosine (C) and thymine (T) and two quinones, 2-methyl-1,4-naphthoquinone or menadione (MQ) and 9,10-anthraquinone (AQ) have been studied using laser flash photolysis technique in organic homogeneous medium, The three pyrimidines have revealed a difference in their extent of reactivity towards the quinones. which has been attributed to their structural difference. Our works have revealed that the difference in structural dimension of the quinones is also responsible for affecting the reactivity of these pyrimidines in homogeneous medium. (C) 2009 Elsevier B.V.
