The 6-bromo-7-hydroxy-coumarin-4-ylmethyl (Bhc) group has been used widely in cage chemistry because of its high molar absorptivity and photolytic efficiency. One of the drawbacks of coumarins however is their low aqueous solubility. Aqueous solubility is important in the behavior of caged compounds because hydrophobic caged compounds might be aggregated in physiological conditions and consequently
6-溴-7-羟基香豆素-4-基甲基(Bhc)基团由于其高的摩尔吸收率和光解效率而被广泛用于笼化学中。然而,香豆素的缺点之一是其低的水溶性。水溶性对于笼状化合物的行为很重要,因为疏水性笼状化合物可能会在生理条件下聚集,因此光裂会受到损害。该实验室先前开发的含溴(8-氮杂-Bhc)或碘(8-氮杂-Ihc)的8-氮杂香豆素-4-基甲基衍生物具有比相关香豆素更高的水溶性。在此,为了改善笼状二酰基甘油内酯(DAG-内酯)的亲水性和管理,将8-氮杂-Bhc和8-氮杂-Ihc引入DAG-内酯结构中。2)显示出优异的光解效率,其允许通过短暂的光辐射快速释放DAG-内酯(1)。8-氮杂-7-羟基-6-碘-香豆素-4-基甲基可以用于笼罩生物活性化合物,尤其是疏水性化合物。
