Latest Patents

Horváth holds a patent for a method of assessing ABC transporter activity using a fluorescent dye accumulation assay. This invention is particularly relevant as ABC multidrug transporters are key players in cancer multidrug resistance. The functional assays developed by Horváth provide important tools for both research and diagnostic applications. His patent describes how, in cells expressing functional ABCG2, ABCB1, or ABCC1 transporters, cellular PG fluorescence is significantly reduced. The invention utilizes fluorescein derivative ester compounds of formula Ia, which are analogs of PG, to assess the activity of these transporters. This accumulation assay serves as a novel tool for the parallel determination of the function of multidrug transporters, especially ABCG2, ABCB1, and ABCC1. The assay is applicable for diagnostic purposes and facilitates the selection, separation, and culturing of specific cell populations expressing these transporters.
