The synthesis, cytotoxicity, and behavior in cell culture of a new set of first- (G1) and second-generation (G2) dendrimers is reported. The surface functionality of these dendrimers has been varied to see whether structure/toxicity relations can be observed. The outermost functional groups are amines that are decorated either with protons, tert-butoxycarbonyl (Boc) or benzyloxycarbonyl (Cbz) protecting
据报道,一组新的第一(G1)和第二代(G2)树状聚合物的合成,细胞毒性和在细胞培养中的行为。这些树枝状聚合物的表面功能已经改变,以查看是否可以观察到结构/毒性关系。最外面的官能团是被质子,叔丁氧羰基(Boc)或苄氧羰基(Cbz)保护基,Boc保护或未保护的天然氨基酸残基,乙二胺配体和/或丹磺酰基荧光标记修饰的胺。使用人MCF-7乳腺癌细胞系在浓度依赖性测定中确定了细胞毒性。HeLa细胞将丹磺酰标记的树状聚合物内化后,通过共聚焦荧光显微镜监测细胞摄取和细胞内分布。
