Novel carbosilane dendrimers, their preparation and their uses. The dendrimers of the invention have secondary, tertiary and quaternary amino groups at their branch ends. Their possible uses include vehicles for carrying anionic-charged molecules in the blood, such as nucleic acids, among them ODN and RNAi, and other anionic drugs with which they have the capacity of interacting, protecting them from interaction with plasma protein and/or increasing their penetration rate in target cells. In the cases where the bond is long-lasting, the dendrimers of the invention can be used to fix anionic molecules to surfaces. Their uses also include their administration as active ingredients to prevent or treat diseases caused by micro-organisms with whose structure and/or life cycle they interfere.
新型碳硅烷树枝状聚合物、其制备方法及其用途。本发明的树枝状聚合物在其分支末端具有仲氨基、叔氨基和季氨基。它们的可能用途包括在血液中携带阴离子带电分子的载体,如核酸(其中包括 ODN 和 RNAi)和其他阴离子药物,它们有能力与这些药物相互作用,保护它们不与血浆蛋白相互作用和/或提高它们在靶细胞中的穿透率。在键合持久的情况下,本发明的树枝状聚合物可用于将阴离子分子固定在表面上。它们的用途还包括作为活性成分用于预防或治疗由其结构和/或生命周期受到干扰的微生物引起的疾病。
