Stable Isotope-Labeled Inhibitors

Stable isotope-labeled inhibitors: one or more atoms are replaced by stable isotopic atoms in the molecular structure of the inhibitor, such as 1H, 12C, 14N, and 16O substituted by D(2H), 13C, 15N, and 17O & 18O respectively. Due to the specificity of stable isotope atoms, they can be used for in vivo and in vitro absorption, distribution, metabolism, and excretion (ADME) studies, etc. By introducing stable isotope-labeled inhibitors, it becomes possible to trace precise metabolic pathways and metabolites within organisms. This valuable information provides a foundation for studying synthetic biology, understanding disease pathogenesis, and unraveling the mechanisms of drug actions [1][2][3].
