产品介绍
SPACE peptide acetate 是一种皮肤穿透肽,可促进分子通过皮肤的转移。

产品描述

SPACE peptide acetate is a skin penetrating peptide that facilitates the transfer of molecules through the skin.

体外活性

SPACE peptide, when conjugates to cargoes such as small molecules and proteins, is able to facilitate their penetration across the stratum corneum into epidermis and dermis. The peptide also exhibits increased penetration into various cells including keratinocytes, fibroblasts, and endothelial cells, likely through a macropinocytosis pathway[1]. SPACE enhances cyclosporine A, penetration into the skin significantly. It does not alter the skin lipid barrier. It interacts with skin proteins and induces changes in skin protein secondary structures (α-helices, β-sheet, random coils and turns). SPACE enhances cyclosporine A skin penetration, via a transcellular pathway, enhancing its partitioning into keratin-rich corneocytes through concurrent binding of SPACE with keratin and cyclosporine A. Interaction between SPACE and keratin best correlates with measured cyclosporine A skin transport[2]. SPACE-peptide in combination with a DOTAP-based ethosomal carrier system can enhance skin delivery of siRNA[3]. The SPACE-ethosomal system enhances hyaluronic acid penetration into porcine skin in vitro by 7.8+/?1.1-fold compared to PBS[4].

体内活性

The efficacy of DOTAP-SES in delivering GAPDH-siRNA into skin is confirmed in BALB/C mice. Topical application of DOTAP-SES on mice skin results in 63.2%±7.7% of GAPDH knockdown, which is significantly higher than that from GAPDH-siRNA PBS (p<0.05) [3].
