Given the growing importance of drug and gene delivery systems, imaging agents, biosensors, and theranostics, there is a need to develop new multifunctional and biocompatible platforms. Here we synthesized and fully characterized a family of novel multifunctional and completely monodisperse dendritic platforms. Our synthetic methodology, based on compatible protecting groups and the attachment of monodisperse triethylene glycol units, allows the control of the generation and differentiation of terminal groups, thus giving rise to multifunctional and perfectly-defined products. A family of dendrons was synthesized and four distinct dendritic structures were chosen from the family in order to determine the effect of the generation and surface groups on their biocompatibility. The stability in serum, cytotoxicity, and hemocompatibility of these products were studied. Our results indicate that these non-toxic, hemocompatible, non-immunogenic, stable and versatile scaffolds may be very interesting candidates for biomedical applications.
鉴于药物和基因递送系统、成像剂、生物传感器和治疗学的重要性与日俱增,因此需要开发新的多功能和生物相容性平台。在此,我们合成了一系列新型多功能、完全单分散树枝状平台,并对其进行了全面表征。我们的合成方法基于兼容保护基团和单分散三甘醇单元的附着,可以控制末端基团的生成和分化,从而产生多功能和完美定义的产品。我们合成了树枝状化合物家族,并从中选择了四种不同的树枝状结构,以确定生成和表面基团对其生物相容性的影响。研究了这些产品在血清中的稳定性、细胞毒性和血液相容性。我们的研究结果表明,这些无毒、血液相容性好、无免疫原性、稳定且用途广泛的支架可能是生物医学应用中非常有趣的候选材料。
