The disclosure encompasses caged compounds such as caged nucleoside phosphoesters (caged nucleotides). In an embodiment, the caged nucleotides include compounds corresponding to those described by formula (I) that may be activated by two-photon excitation, and methods of synthesis of such compounds. 8-Bromo-7-hydroxyquinoline-caged ATP was synthesized and examined for its photochemistry as a biologically useful, temporally and spatially controlled ATP-releasing reagent. The combination of two-photon excitation hydrolysis and activation of caged ATP enables methods for finely focusing ATP activation at the sub-cellular level or to a greater depth of activation, thereby providing improved resolution of ATP-dependent processes at the cellular level.
该披露涵盖了笼状化合物,例如笼状核苷酸磷酸酯(笼状核苷酸)。在一种实施方式中,笼状核苷酸包括与式(I)所描述的化合物相对应的化合物,可以通过双光子激发激活,并且还涉及这些化合物的合成方法。8-溴-7-羟基喹啉笼状ATP已被合成并检查其光化学作用作为一种生物学上有用的、时间和空间可控的ATP释放试剂。双光子激发水解和激活笼状ATP的组合使得在亚细胞水平或更大深度的ATP激活方法得到了精细聚焦,从而提供了在细胞水平上改进ATP依赖过程的分辨率的方法。
