Abstract
The present invention relates to use of SC79 or an analogue thereof in the preparation of a blood-brain barrier permeability regulator. The blood-brain barrier permeability regulator comprises SC79 or an analogue thereof as an active ingredient, which down-regulates expression of tight junction proteins Claudin-5 and Occludin by activating Claudin-5 and Occludin signaling pathway downstream the protein kinase B, and thereby increases the blood-brain barrier permeability, and enhances the efficiency of transportation of a brain targeting drug delivery system, especially, an Angiopep-2-modified glycolipid nano-delivery system, into the brain. The present invention also relates to a kit comprising the blood-brain barrier permeability regulator and a brain targeting drug delivery system. According to the present invention, use of the blood-brain barrier permeability regulator in combination with a brain targeting drug delivery system can enhance the efficiency of transportation of a brain targeting drug delivery system into the brain, and thereby improve the therapeutic efficacy of the brain targeting drug delivery system.
