Studies on DNA dynamics using 2-N-tert-butylaminoxylpurines

Abstract

2-N-tert-Butylaminoxylpurines (1) and (2) were synthesized from 2'-deoxy-6-chloropurine derivative by lithiation strategy. Effects of motion of 1 and 2 on EPR spectra were studied by EPR measurement in sucrose solution at various temperatures. The single stranded and duplexed 15-mers containing 1 showed the clear difference in the EPR spectra to indicate 1 has the potential to accurately study the dynamics of purine residues.
