Abstract
The present invention relates to methods of forming metal-pyridine derivative complexes using pericyclic reactions with metal-1,2,4-triazine derivative complexes and a dienophile as the reactants. The reactants are bioorthogonal and the methods are particularly useful in preparing imaging agents.
Claims28
A method of forming a pyridine;
- the method comprising:
- contacting a compound comprising a 1,2,4-triazine with a compound comprising a dienophile to form a compound comprising a pyridine,
- wherein the 1,2,4-triazine is complexed to a metal.
A kit for medical imaging or for imaging a biological sample, the kit comprising:
- a compound comprising a 1,2,4-triazine;
- and
- a compound comprising a dienophile;
- wherein the 1,2,4-triazine is complexed to a metal;
- and
- wherein either:
- A) the compound comprising the 1,2,4-triazine further comprises a biological targeting moiety;
- or
- B) the compound comprising the dienophile further comprises a biological targeting moiety.
