An architectural polymer containing hydrophobic isoxazole-based dendron and hydrophilic polyethylene glycol linear tail is prepared by a combination of the robust ZnCl2 catalyzed alkyne-nitrile oxide 1,3-dipolar cycloaddition and esterification chemistry. This water soluble amphiphilic telodendrimer acts as a macromolecular biologically active agent and shows concentration dependent reduction of glioblastoma (U251) cell survival.
一种包含疏水异噁唑基树状结构和亲水聚乙二醇线性尾部的建筑聚合物是通过强大的ZnCl2催化的炔基-亚硝基氧化物1,3-二极环加成和酯化化学的组合制备的。这种水溶性两性端树聚合物作为一种大分子生物活性剂,表现出浓度依赖性的减少胶质母细胞瘤(U251)细胞存活的效果。
