RESUMO
To study the behavior of MDM2-p53 inhibitors in a disease-relevant cellular model, we have developed and validated a set of bioorthogonal probes that can be fluorescently labeled in cells and used in high-content screening assays. By using automated image analysis with single-cell resolution, we could visualize the intracellular target binding of compounds by co-localization and quantify target upregulation upon MDM2-p53 inhibition in an osteosarcoma model. Additionally, we developed a high-throughput assay to quantify target occupancy of non-tagged MDM2-p53 inhibitors by competition and to identify novel chemical matter. This approach could be expanded to other targets for lead discovery applications.
