Conjugation is an important reaction that enables coupling of molecules. Many protocols exist for the synthesis of binary conjugates from two different molecules or for the polyvalent display of a single molecule. There aren't many methods for the synthesis of ternary conjugates. However, methods for ternary conjugation are important for understanding the interplay of interactions between three biomolecules (or any three molecules per se). A strategy for ternary bioconjugation using inverse electron demand Diels–Alder reaction with tetrazine is studied. Ternary conjugation was demonstrated by the reaction of a model glyco-peptide binary conjugate with a fluorescent tagged olefin.
共轭反应是一种重要的反应,能够实现分子的耦合。存在许多用于合成两种不同分子之间的二元共轭物或单个分子的多位展示的方案。但对于合成三元共轭物的方法并不多。然而,三元共轭的方法对于理解三个
生物分子(或任意三个分子本身)之间的相互作用至关重要。研究了一种利用逆电子需求Diels-Alder反应与
四唑进行三元
生物共轭的策略。通过模型糖肽二元共轭物与荧光标记的烯烃之间的反应,展示了三元共轭。
