生化/生理作用

Maleimide (thiol reactive) functionalized trans-cyclooctene derivative for incorporation of the cyclooctene moiety into thiol 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 thiol to be modified and the reactive alkene.

    Determining nanoscale protein distribution via Photoactivated Localization Microscopy (PALM) mandates precise knowledge of the applied fluorophore's blinking properties to counteract overcounting artifacts that distort the resulting biomolecular distributions. Here, we present a readily applicable methodology to determine, optimize and quantitatively

    1,2,4,5-Tetrazines have been established as effective dienes for inverse electron demand [4 + 2] Diels-Alder cycloaddition reactions with strained alkenes for over 50 years.

    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.
