Displaying 1 results of Tucatinib Stable Isotopes Tucatinib is a small molecule kinase inhibitor that selectively targets HER2-positive breast cancer. Stable isotopes of Tucatinib are non-radioactive forms of the drug that have the same chemical and physical properties as the regular drug, but with different atomic masses. These isotopes are used in research applications to study the metabolism, pharmacokinetics, and pharmacodynamics of Tucatinib, as well as for drug development and clinical trials. The availability of stable isotopes of Tucatinib is important in advancing our understanding of the drug's mechanism of action and its potential therapeutic applications.
