Special Issue Information

Dear Colleagues,

Mass Spectrometry Imaging (MSI) holds great potential in the fields of drug pharmacokinetics and drug delivery systems. It offers the unique advantage of providing spatially resolved information about the distribution and behavior of drugs within biological tissues.

In drug pharmacokinetics, MSI enables for the direct visualization of drugs and their metabolites within tissues, allowing for a comprehensive understanding of their absorption, distribution, metabolism, and excretion. These spatially resolved data aid in determining drug efficacy, optimizing dosage regimens, and advancing personalized medicine approaches.

Additionally, MSI plays a vital role in evaluating drug delivery systems. It offers valuable insights into drug release profiles, targeting efficiency, and potential off-target effects by visualizing drugs' spatial distribution and release of kinetics from various delivery platforms, such as nanoparticles and liposomes. This information assists in the optimization of drug delivery systems for improved therapeutic outcomes and minimized adverse effects.

Various MSI techniques, including MALDI-MSI and DESI-MSI, have been extensively employed in preclinical and clinical studies to investigate drug pharmacokinetics and delivery systems. These techniques offer high spatial resolution, sensitivity, and the ability to analyze a diverse range of compounds. By providing detailed spatial information, they contribute to the development of safer and more effective drug therapies.

Supervised by Prof. Dr. Mitsutoshi Setou and assisted by our Topical Advisory Panel Member Dr. Ariful Islam, this Special Issue aims to gather original research articles and reviews about Mass Spectrometry Imaging for drug pharmacokinetics and drug delivery systems.

Knowledge of gender-specific drug distributions in different organs are of great importance for personalized medicine and reducing toxicity. However, such drug distributions have not been well studied. In this study, we investigated potential differences in the distribution of imipramine and chloroquine, as well as their metabolites, between male and female kidneys. Kidneys were collected from mice treated with imipramine or chloroquine and then subjected to atmospheric pressure matrix-assisted laser desorption ionization-mass spectrometry imaging (AP-MALDI-MSI). We observed differential distributions of the drugs and their metabolites between male and female kidneys. Imipramine showed prominent distributions in the cortex and medulla in male and female kidneys, respectively. Desipramine, one of the metabolites of imipramine, showed significantly higher (*** p < 0.001) distributions in the medulla of the male kidney compared to that of the female kidney. Chloroquine and its metabolites were accumulated in the pelvis of both male and female kidneys. Interestingly, they showed a characteristic distribution in the medulla of the female kidney, while almost no distributions were observed in the same areas of the male kidney. For the first time, our study revealed that the distributions of imipramine, chloroquine, and their metabolites were different in male and female kidneys. Full article
