Structural Studies of 5-Ethyl-2′-Deoxyuridine by Selective Pulse 1H DPFGSE NOE Spectroscopy and PM3 Calculations

Abstract

The solution conformation of 5-ethyl-2′-deoxyuridine (EDU) has been calculated from the vicinyl proton-proton NMR coupling constants and nuclear Overhauser (NOE) distances using excitation sculpting of selective pulses (Double Pulsed Field Gradient Spin Echo NOE) at 500 MHz and molecular modelling (PM3) studies.
