1,2,4-Triazines Are Versatile Bioorthogonal Reagents. 2015

David N Kamber, and Yong Liang, and Robert J Blizzard, and Fang Liu, and Ryan A Mehl, and K N Houk, and Jennifer A Prescher

A new class of bioorthogonal reagents, 1,2,4-triazines, is described. These scaffolds are stable in biological media and capable of robust reactivity with trans-cyclooctene (TCO). The enhanced stability of the triazine scaffold enabled its direct use in recombinant protein production. The triazine-TCO reaction can also be used in tandem with other bioorthogonal cycloaddition reactions. These features fill current voids in the bioorthogonal toolkit.

UI MeSH Term Description Entries
D007202 Indicators and Reagents Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
