Synthesis and DNA Binding Properties of a Purine Analogue of Bisbenzimide
摘要:
The synthesis of a purine containing analogue (1) of bisbenzimide (2) and its DNA binding properties are described. Analogue 1 is found to have increased tolerance for binding to GC sites implying the formation of the new hydrogen bonds between guanine-2-NH2 in the minor groove of DNA and the concave purine N3 atom of 1.
