General description

Phenoxazine dyes, including several Nile blue analogs, are known to localize selectively in animal tumors.


Phenoxazine is a tricyclic 2′deoxycytidine analog that has been used to improve stacking interactions between heterocycles of oligonucleotide/RNA hybrids and to enhance cellular uptake.

The overall goal of our research is to develop effective new photosensitizers for tumor-selective photodynamic therapy. Phenoxazine dyes, including several Nile blue analogues, are known to localize selectively in animal tumors. Structural modifications yielded several series of analogues with substantially...

One of the major barriers to the development of antisense therapeutics has been their poor bioavailability. Numerous oligonucleotide modifications have been synthesized and evaluated for enhanced cellular permeation with limited success. Phenoxazine, a tricyclic 2' deoxycytidine analog, was designed to...

We examined the in vivo antiviral activities of 2-amino-4,4α-dihydro-4α-7-dimethyl-3H-phenoxazine-3-one (Phx-1), 3-amino-1,4α-dihydro-4α-8-dimethyl-2H-phenoxazine-2-one (Phx-2), and 2-aminophenoxazine-3-one (Phx-3) against herpes viruses. The virus yield three days after administration, changes in the 6-degree's lesion scores, and the morbidity were assessed after herpes simplex virus...

Many industrial pollutants, xenobiotics, and industry-important compounds are known to be oxidized by peroxidases. It has been shown that highly efficient peroxidase substrates are able to enhance the oxidation of low reactive substrate by acting as mediators. To explore this...
