Project TitleTetrazine-Trans-Cyclooctene Ligation as the Basis of PET/SPECT Probes and Radiotherapies
Track Code2011-002
Short Description

The innovation is a new class of ligation reaction that proceeds with exceptionally high reaction rates.  The reaction involves the cycloaddition of 1,2,4,5-tetrazene derivatives with dienophiles.  The reaction tolerates a broad rate of functionality, including thiols and primary amines, and the reaction proceeds in high yield in organic solvents and water.  Examples of tetrazene ligation reactions are demonstrated in biological media and in cell lysate.  The selectivity and aqueous compatibility of the reaction make it suitable for numerous in vivo and in vitro applications, including the ligation reactions of small molecules, peptides, proteins, oligonucleotides, other types of polymers, nanoparticles, and on surfaces (e.g. glass slides, gold).  Also described are new methods for producing tetrazines, cyclopropene derivatives, and trans-cyclooctene derivatives.
