Slovesnova, Nataliya V. published the artcileSynthesis of new water-soluble polyarene-substituted naphtho[1,2-d]oxazole-based fluorophores as fluorescent dyes and biological photosensitizers, Product Details of C10H9NO4S, the publication is Dyes and Pigments (2022), 110410, database is CAplus.
Two new water-soluble PAH-substituted (PAH – polyaromatic hydrocarbon) naphtho[1,2-d] [1,3]oxazole dyes 1-2 were synthesized and investigated for intramol. charge transfer (ICT) behavior, aggregation, and ability to fluorescent staining and photosensitization on living cancer cells of HeLa and Vero cultures. To make clear this behavior a detailed anal. of the relationship between the structure and photophys. properties 1-2 were carried out based on exptl. and computation data. As a result of the staining experiment, there was a diffuse distribution in the cytoplasm of 2-(9-anthracenyl)-containing naphthoxazole 1 as a hydrophilic fluorophore. Whereas 2-(1-pyrenyl)-derivative 2 showed accumulation in the endoplasmic reticulum, as well as addnl. distribution in lipid bilayers. Photodynamic activity of type II was confirmed for the cationic exogenous photosensitizer 2: the IC50 value in the case of HeLa cell culture was 0.50μM. The radical mechanism of photodynamic activity was determined by the EPR method.
