Displaying 2 results of Camptothecin Stable Isotopes Camptothecin stable isotopes are a set of isotopically labeled compounds used in research and drug development. Camptothecin is a natural alkaloid known for its anti-cancer properties, but its use is limited due to its toxicity and instability. The stable isotopes of camptothecin provide a valuable tool for studying its pharmacokinetics and metabolism, as well as for synthesizing analogs with improved properties. These isotopes are also used in clinical trials to track drug distribution and efficacy.
