pyridazine elimination reaction between tetrazines and allylic substituted trans‐cyclooctenes (TCOs) is a key player in bioorthogonal bond cleavage reactions. Determining the rate of elimination of alkylamine substrates has so far proven difficult. Here, we report a fluorogenic tool consisting of a TCO‐linked EDANS fluorophore and a DABCYL quencher for accurate determination of both the click and release
四嗪和烯丙基取代的反式环辛烯(TCO)之间的逆电子需求狄尔斯-阿尔德哒嗪消除反应是生物正交键断裂反应的关键参与者。迄今为止,确定烷基胺底物的消除率很困难。在这里,我们报告了一种由 TCO 连接的 EDANS 荧光团和 DABCYL 猝灭剂组成的荧光工具,用于准确测定任何四嗪在生理相关浓度下的点击和释放速率常数。
