Aplicación
Succinimidyl ester/NHS (amine reactive) functionalized trans-cyclooctene derivative for incorporation of the cyclooctene moiety into amine containing compounds or biomolecules. Trans-cyclooctenes are useful in strain-promoted, copper-free, click chemistry cycloaddition reactions with 1, 2, 4, 5-tetrazines. This cyclooctene will react with tetrazine functionalized compounds or biomolecules, without the need for a catalyst, to result in a stable covalent linkage. The 4+2 inverse electron demand Diels-Alder cycloaddition between trans-cyclooctene and tetrazines is the fastest biologically compatible ligation technology reported, and has had many applications in biological labeling and imaging. The PEG spacer allows for increased water solubility, less aggregation, and an increased distance between the amine to be modified and the reactive alkene.

Bioorthogonal tetrazine cycloadditions have been applied to live cell labeling. Tetrazines react irreversibly with the strained dienophile norbornene forming dihydropyrazine products and dinitrogen. The reaction is high yielding, selective, and fast in aqueous media. Her2/neu receptors on live human breast
