Pharmaco*kinetics (PK)is the study of the time course of drug’s absorption, distribution, metabolism, and excretion (ADME), what the body interact with a drug, related to the movement of drug into, pass, and out of the body. In order for a drug to be effective in the body, enough of the active form must reach the target to elicit the desired effect. The compound with the best activity against the target enzyme or receptor may have very poor ADME characteristics such as metabolic instability or poor intestinal absorption. When choosing a lead candidate from multiple compounds, the activity of the drug in the efficacy screen must be balanced with acceptable ADME and stability characteristics. Pharmaco*kinetic studies with mass spectrometry bioanalysis can provide the quantitative information about the half-life of the administrated compound from in vitro and in vivo test, and more useful information of how quickly it can be metabolized or excreted by enzymatically or nonenzymatically. To track the drug accumulation and distribution in organism from in vivo PK study, the mass spectrometry imaging and quantification can come up with innovative solutions to quantify dynamic drug exposures in all targeted tissues, or using artificial intelligence modeling to predict the drug exposure in disease or normal organs.

Mass spectrometry imaging (MSI)is an emerging technique that allows molecular visualization of the distribution of drugs, lipids, peptides, proteins and metabolites in a two-dimensional space directly in biological tissues. MSI allows unlabeled drug compounds and drug metabolites to be detected and identified and quantified according to their mass-to-charge ratios (m/z) at high resolution in complex tissue environments. This technique has better specificity and provides the possibility to combine histological data with MS ones and to visualize simultaneously the distribution drugs or biomarkers in relation to tumor heterogeneity, provide new understandings of the dynamic processes impacting drug uptake and metabolism at the local sites targeted by therapy.

The use of bioanalytical technologies such as quantitativeliquid chromatography-mass spectrometry(LC-MS/MS) has been accepted as the gold-standard technology to support PK and drug metabolism studies. It comes significant improvements in assay sensitivity, selective and specificity, plus the potential to reduce assay time per samples, and the detection of compounds of interest in different matrices, no matter how complex - including plasma, blood, serum, urine, faces, spinal fluid, skin, muscle, artery, myocardium, liver and kidney, and a variety of tumor types.
