Stable isotope-labeled compounds are used as environmental pollutant standards for the detection of air, water, soil, sediment and food.
In addition to treating various diseases, isotopes are used for imaging, diagnosis, and newborn screening.
Small molecule compounds labeled with stable isotopes can be used as chemical reference for chemical identification, qualitative, quantitative, detection, etc. Various types of NMR solvents can be used to study the structure, reaction mechanism and reaction kinetics of compounds.
Stable isotope labeling allows researchers to study metabolic pathways in vivo in a safe manner.

Description | Topotecan-[d5] is the labelled analogue of Topotecan. Topocecan is a semisynthetic derivative of camptothecin with antineoplastic activity. During the S phase of the cell cycle, topotecan selectively stabilizes topoisomerase I-DNA covalent complexes, inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when complexes are encountered by the DNA replication machinery. Camptothecin is a cytotoxic quinoline-based alkaloid extracted from the Asian tree Camptotheca acuminata. |
