Abstract: 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.
