  Fluorescent nucleosides with ‘on–off’ switching function, pH-responsive fluorescent uridine derivatives

  摘要：

  We synthesized various pH-responsive fluorescent deoxyuridine derivatives (1a-g). These fluorescent nucleosides exhibited distinctive fluorescence at 470-600 nm in aqueous solvents containing methanol only at acidic to neutral pH values. In particular, 1f exhibited strong fluorescence only at pH range of 3.1-7.2 with a pK(a) of 6.1. Such pH-sensitive fluorescent nucleosides can be used as 'on-off' fluorescence switch for monitoring pH change in biological systems, particularly for cancer cell detection. (C) 2012 Elsevier Ltd.
