The present invention addresses the problem of providing an endocytosis enhancer comprising associates formed from a fluorescent protein. The fluorescent protein is preferably any one selected from the group consisting of a white fluorescent protein, a red fluorescent protein, a yellow fluorescent protein, a blue fluorescent protein and a green fluorescent protein. The endocytosis enhancer according to the present invention can enhance the cellular uptake of a drug, which is encapsulated in micelles each formed from a fluorescent-protein-supported carbosilane dendrimer, through endocytosis.

Endocytosis enhancer for drug delivery system

The present invention relates to a targeting-type capsule for drug delivery systems. The present invention addresses the problem of providing a capsule for drug delivery systems by utilizing the reactivity of a thiol with an alkyl halide, wherein the capsule comprises a silole-containing carbosilane dendrimer and a labeling protein containing a target recognition site (e.g., green fluorescent protein), can include a biological polymer or another molecule therein, and can deliver the biological polymer or the like selectively into a target cell.

The object of the present invention is to provide an aggregatable carrier material for drug delivery system and a micelle formed thereof. The present invention provides an aggregatable carrier material for drug delivery system, which is formed by utilizing the reaction between thiol group and alkyl halide. It is formed by using carbosilane dendrimers containing silole and labeled proteins such as green fluorescent protein in aqueous solvent or in mixed solvent of the aqueous solvent and organic solvent. The micelle composed of the material may incorporate compounds having a variety of molecular weight and biopolymers in the aqueous solvent.

The present invention is related to a targeted type shell for drug delivery system. The object of the present invention is to provide the targeted type shell for DDS, which comprises a carbosilane dendrimer containing a silole produced by which is formed by utilizing the reaction between thiol group and alkyl halide, and a targeted protein containing a labeled proteins such as green fluorescent protein with a target recognition site. The shell may incorporate compounds having a variety of molecular weight and biopolymers, and selectively deliver them into targeted cells.
