A selective turn-on fluorescence strategy for the detection of 5-hydroxymethyl-2′-deoxycytidine†
Abstract
A new type of 1,3-O,N-heterocycle, including two fluorescent derivatives, has been synthesised by the reaction of the hydroxyl and amine groups of 5-hydroxymethyl-2′-deoxycytidine (hmC). This reactivity is shown to enable the selective recognition of hmC over other natural nucleotides in aqueous buffer.
