点击化学
点击反应是一类具有定量、快速、高效、立体选择性、很少甚至没有副产物生成、反应条件温和等特点的化学反应。点击化学在制药和生物技术行业的生物偶联应用中具有广泛的应用。
传统的叠氮-炔点击反应是指在铜(I)催化的条件下叠氮化物和端炔的1,3-偶极环加成反应。众所周知,铜(I)具有细胞毒性,可损伤红细胞,使传统的点击反应在生物医学应用中受到限制。澳门新莆京游戏大厅的聚乙二醇-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。澳门新莆京游戏大厅PEG-环辛炔衍生物具有良好的水溶性和生物相容性,可广泛应用于多肽、蛋白质和药物传递送中,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,以达到对药物的缓释控制目的。
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;
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;
键凯具有提供大批量生产高品质高性价比PEG-DBCO产品的能力,包括非GMP和GMP级产品。下面是澳门新莆京游戏大厅生产的PEG DBCO产品的详细信息,具有不同分支、分子量和功能的PEG和单分散PEG DBCO衍生物可以通过客户特定合成服务进行合成。
