Stable or radioisotope-labeled compounds allow precise tracking and quantification of individual atoms in metabolic pathways. Stable isotopes generally do not change molecular properties but may slightly affect metabolic kinetics; radioactive isotopes may interfere with cells. Markers can distinguish endogenous and exogenous metabolites, reduce false positives, and are beneficial to quantification and reconstruction of metabolic pathways^[2].
In cell culture or enzymatic reactions, the use of isotope markers can precisely control the concentration and exposure time, making it easy to study metabolic reactions and enzyme activities. Through stable isotope analytical metabolomics (SIRM), cellular metabolic networks can be studied, key metabolic nodes and regulatory mechanisms can be identified, and targets can be provided for compound development.
Isotope-labeled compounds can be used in competition binding experiments to evaluate the affinity and binding kinetics of compounds to receptors to help optimize design. Stable isotope labels are used as internal standards in mass spectrometry analysis to improve analysis accuracy and reproducibility and reduce matrix effect interference^[3].
