Matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry (IMS) has emerged as a powerful technology in drug discovery and development for determining label-free distributions of drugs and their metabolites in tissues. In the past few years, MALDI IMS has been further advanced to achieve absolute quantification of drug distributions. Moreover, MALDI IMS has also been applied to map endogenous molecule distribution in the context of specific histological features or pathological phenotypes to provide a molecular basis for tissue histology/pathology, facilitating pathway analysis and understanding mechanistic principles of diseases. Here, representative examples will be presented to demonstrate how MALDI IMS is applied to quantitively visualize pharmacokinetics and identify localized molecular markers in drug discovery and development.
