TCO(反式环辛烯)基团以其双键上的高内应变而著称,这促进了与四唑衍生物的应变促进的逆需求迪尔斯-阿尔德反应(SPIEDAC)。即使在各种官能团存在的情况下,这种反应也能选择性地进行,因此它可以用作点击化学工具。利用TCO的点击化学不需要金属催化剂,并且以快速的反应速率为其主要特点。这种点击化学满足了生物正交反应的标准(快速、选择性、生物相容性、无金属),并发现在蛋白质标记和成像等多种应用中都有用途。1,2,3,4)
TCO(反式环辛烯)与四唑衍生物之间的反应速率被描述为[TCO > TCO*]和[轴向 > 赤道向]。然而,在生物环境中,特别是在硫醇存在的情况下,其稳定性被描述为[TCO* > TCO]。5)
此外,最近的报告表明,在无金属催化剂的条件下,2-TCO衍生物与四唑衍生物之间的反应可以展示“点击-释放”反应,这为它们作为前药的角色展示了前景。6,7,8,9)
基于这些特性,我们提供了一系列有用的TCO衍生物,适用于合成,包括4-硝基苯基碳酸酯(NPC)酯、带有PEG延伸的胺、生物素、DBCOs(二氟环辛基苯丙氨酸)、NHS(N-羟基琥珀酰亚胺)酯、马来酰亚胺衍生物等。
