Application

5-[4-(1,2,4,5-Tetrazin-3-yl)benzylamino]-5-oxopentanoic acid may be used in the synthesis of a PEG-tetrazine (PEG-Tz) macromer via acid-amine conjugation. This macromer can undergo click reaction with norbornene-functionalized peptides to form hydrogels that is useful for 3D cell culture.
Acid functionalized tetrazine for inverse electron demand Diels-Alder cycloaddition reactions. The tetrazine will react with strained alkenes such as transcyclooctene, norbornene and cyclopropene to yield a stable covalent linkage. Tetrazines have proven useful in bioorthogonal reactions for many biological imaging and bioconjugation applications.

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
