Incorporating in a single step hydrogene isotopes into nucleic acid derivatives


Facilitating the deuterium and tritium labeling of molecules containing nucleic bases such as many compounds of pharmacological interest? This is what researchers from SCBM (CEA-Joliot) in partnership with teams from SPI (CEA-Joliot) and Toulouse managed to achieve. The study was published in Angewandte Chemie.

Abstract from the original paper:

A general approach for the efficient hydrogen‐isotope exchange of nucleobase derivatives is described. Catalyzed by ruthenium nanoparticles, using mild reaction conditions, and involving either D2 or T2 as isotopic sources, this reaction possesses a wide substrate scope and a high solvent tolerability. This novel method facilitates the access to essential diagnostic tools in drug discovery and development: tritiated pharmaceuticals with high specific activities and deuterated oligonucleotides suitable for use as internal standards during LC‐MS quantification.




















Selective hydrogen-isotope exchange (HIE) reaction developped by  SCBM team has many benefits presented in this scheme © SCBM/CEA
