Measuring pharmacodynamics is crucial for drug development, but traditional pharmacodynamic studies based on tissue dissection and subsequent biochemical analysis are labor- and resource-intensive. We developed a non-invasive imaging method to efficiently and rapidly visualize the pharmacodynamics of kinase inhibitors and degraders using an engineered kinase-modulated bioluminescent indicator.
