Low-generation dendrimers containing a high density of surface hydroxyl groups, and methods of synthesis thereof are provided. In particular, oligo ethylene glycol (OEG)-like dendrimers with a high surface functional groups at relatively low generations (e.g. ˜120 hydroxyls in the third generation, with a size of just 1-2 nm) is described. Dendrimer formulations including one or more prophylactic, therapeutic, and/or diagnostic agents, and methods of use thereof are also described. The formulations are suitable for topical, enteral, and/or parenteral delivery for treating one or more diseases, conditions, and injuries in the eye, the brain and nervous system (CNS), particularly those associated with pathological activation of microglia and astrocytes.
本文提供了含有高密度表面羟基基团的低代数树状分子及其合成方法。具体来说,本文描述了具有高表面功能基团的寡聚乙二醇(OEG)类树状分子,其代数相对较低(例如第三代中约有120个羟基,大小仅为1-2纳米)。本文还描述了包括一种或多种预防性、治疗性和/或诊断性药物的树状分子制剂及其使用方法。这些制剂适用于局部、肠道和/或静脉注射治疗与微胶质细胞和星形胶质细胞病理激活相关的眼部、大脑和神经系统(CNS)中的一种或多种疾病、状况和损伤。
