PV-10 is an injectable formulation of rose bengal disodium (RB) (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein disodium salt), which is a small molecule halogenated xanthene and PV-10's active pharmaceutical ingredient.
The different types of aggregation between rosamines once anchored to the Ti[O.sub.2] molecules in the film and their implications on their respective spectra can be explained in terms of the type of interaction between rosamine and Ti[O.sub.2], taking into account that the transition dipole moments for both rosamines are located along the xanthene ring.
Therefore, the photodynamic efficiency of four xanthene dyes (Rose Bengal, erythrosin B, eosin Y, and fluorescein) was determined in the present study by comparing their medium inhibitory concentration ([IC.sub.50]) values in HEp2 cells, their photodynamic activity using uric acid as a chemical dosimeter, and their octanol-buffer partition coefficient (log P).
