调节体内小分子化学的能力将使成像和药理学的探索成为可能。然而,这些目标的实现将需要具有高特异性和精确控制的反应。在这里,我们证明了在体外和体内的高度特异性Staudinger-Bertozzi结扎光控。我们简单的方法,光笼的关键膦原子,允许与光化学试剂,可以为特定的应用程序设计的简便生产。所得到的化合物,这是稳定和有效地激活,使空间标记的代谢引入叠氮化物在体外和活斑马鱼。
The ability to regulate small molecule chemistry in vivo will enable new avenues of exploration in imaging and pharmacology. However, realization of these goals will require reactions with high specificity and precise control. Here we demonstrate photocontrol over the highly specific Staudinger–Bertozzi ligation in vitro and in vivo. Our simple approach, photocaging the key phosphine atom, allows for the facile production of reagents with photochemistry that can be engineered for specific applications. The resulting compounds, which are both stable and efficiently activated, enable the spatial labeling of metabolically introduced azides in vitro and on live zebrafish.
