growing application of tetrazine bioorthogonal chemistry, it is still challenging to access tetrazines conveniently from easily available materials. Described here is the de novo formation of tetrazine from nitriles and hydrazine hydrate using a broad array of thiol‐containing catalysts, including peptides. Using this facile methodology, the syntheses of 14 unsymmetric tetrazines, containing a range of

2-pyridyltetrazines serve a dual role by enabling protein purification through metal chelation and still maintaining their rapid kinetics in bioorthogonal reactions. ABC-tagging is successful for proteins tagged at the C- or N-terminus or at internal positions, is successful in complex mixtures including cell lysate, and can be carried out on-resin to generate multidomain proteins.
基于 2-吡啶基四嗪的亲和生物正交化学标签 (ABC-tags) 具有双重作用,通过金属螯合实现蛋白质纯化,并在生物正交反应中仍然保持其快速动力学。ABC 标记对于在 C 端或 N 端或内部位置标记的蛋白质是成功的,在包括细胞裂解物在内的复杂混合物中也是成功的,并且可以在树脂上进行以生成多结构域蛋白质。
