Antiviral activity spectrum of phenoxazine nucleoside derivatives

Antiviral Research, 2019
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 ...

Investigation of the chemistry of phenoxazines

Chemistry of Heterocyclic Compounds, 1972
Depending on the position of the annelated benzene ring, benzophenoxazinones add thiophenols in the benzenoid, quinonoid, or both parts of the molecule to give mono- or diarylmercapto derivatives. A substituent in the benzenoid portion of the molecule hinders polarographic reduction and shifts the visible absorption band bathochromically, while a ...

Tricyanovinylation of phenoxazine and phenothiazine

Chemistry of Heterocyclic Compounds, 1985
In the reaction of tricyanoethylene (TCE) with phenoxazine in DMF at 100 ° C, in addition to the principal reaction product —viz., 3-(tricyanovinyl) phenoxazine — 3-dicyanomethylene-3H-phenoxazine and 3-phenoxazinyl-3-(3H-phenoxazinylene)-cyanomethane are formed in small amounts.
