Recently 5-hydroxymethyl-2'-deoxycytidine (5hmdC), 5-formyl-2'-deoxycytidine (5fdC), and 5-carboxyl-2'-deoxycytidine (5cadC) were discovered in mammalian DNA as oxidation products of 5-methyl-2'-deoxycytidine (5mdC) induced by the ten-eleven translocation family of enzymes. These oxidized derivatives of 5mdC may not only act as intermediates of active cytosine demethylation in mammals but also ...

Adenosine Analogs, Conformation, NMR The solution conformation of adenosine(/Oribosides modified at the 2', 3' or 5' position is derived from the analysis o f the HRNM R spectra of the ribose protons. The conformational equilibria of the furanoside rings are described by the two state N <-+ S model introduced by Altona and Sundaralingam. The new compounds studied are: 2'-thiobenzoyl-2'-deoxyade...
