早在1961年,Witting在“ZurExistenz NiedergliedrigerCycloalkine,I和II”中就提到苯基叠氮与环辛炔能够发生无铜催化的点击反应。然而,大多数环辛炔试剂又不具有良好的水溶性,限制了它们在生物医药中的应用。
键凯科技拥有一系列聚乙二醇-环辛炔衍生物的**(发明**,**号:ZL201310300951.6),这些环辛炔衍生物可以在无铜的条件下与叠氮化物反应,从而使后处理非常简单,消除了传统点击化学的细胞毒性问题。 键凯科技PEG-环辛炔衍生物具有良好的水溶性和生物相容性。聚乙二醇衍生物广泛应用于多肽、蛋白质和药物传递中,以延长半衰期,降低免疫原性和毒性,也可与药物分子通过PEG化结合,作为水凝胶的一部分。
新型PEG环新炔衍生物的优点:
无铜条件下与叠氮化物进行点击反应
与传统的点击化学相比,没有细胞毒性问题,
良好的水溶性和生物相容性
在药物输送中的应用,可以延长半衰期,降低药物免疫原性和毒性
多臂PEG环辛炔衍生物可用于形成水凝胶
