NMR study of 9,9′-(alkane-α,ω-diyl)diadenine
Abstract
The relationship between NMR chemical shifts of adenine ring protons of low concentrations of 9,9′-(alkane-α,ω-diyl)diadenine and the length of the polymethylene chains has been investigated in buffer solutions at pD 1.0, 7.0 and 13.0 and in organic solvents such as CD3OD,(CF3)2CDOD, [2H6]dimethyl sulfoxide and CF3COOD. The chemical shifts were compared with those of 9-(ω-bromoalkyl)adenine.
