The phenoxazine scaffold is widely used to stabilize nucleic acid duplexes, as a part of fluorescent probes for the study of nucleic acid structure, recognition, and metabolism, etc. Here we present the synthesis of phenoxazine-based nucleoside derivatives and their antiviral activity against a panel of structurally diverse viruses: enveloped DNA herpesviruses varicella zoster virus (VZV) and human
The 8-oxoG-clamp, a specific fluorescent probe for 8-oxo-deoxyguanosine (8-oxo-dG), was incorporated into the oligodeoxynucleotide (ODN) within or at the 3 '-end of the purine and the pyrimidine sequences. Based on the UV-melting temperature, the 8-oxoG-clamp showed slightly lower stabilizing effects on the duplexes containing 8-oxo-dG at the complementary site than that with dG. On the other hand, 8-oxo-dG in DNA was selectively detected by fluorescence quenching of the 8-oxoG-clamp. (C) 2008 Elsevier Ltd. All rights reserved.
