维生素 B 12结合物在生物科学中得到广泛研究。由于光提供时空控制,我们决定开发一种制备维生素 B 12结合物的方法,该结合物在暴露于光时会释放束缚分子。在此,我们报告了维生素 B 12衍生物,其具有适合与胺、叠氮化物和炔烃结合的光不稳定接头。这种偶联物的潜在应用是广泛的,包括将药物、标签和显像剂输送到它们的作用位置和时空释放。

wild-type enzyme to organic synthesis has been demonstrated in the regioselective acylation of nucleosides in anhydrous dimethylformamide (with 65-100% regioselectivity at the 5'-position), in the enantioselective hydrolysis of N-protected and unprotected common and uncommon amino acid esters inmore » water (with 85-98% enantioselectivity for the L-isomer), and in the synthesis of di- and oligopeptides
