Transdermal Peptide acetate(888486-23-5 free base) 是一种 11 个氨基酸的肽，与 Na+/K+-ATPase β 亚基 (ATP1B1) 结合，主要与 ATP1B1 的 C 端相互作用。透皮肽可以增强许多大分子的透皮传递。透皮肽 TD 1 酰胺是一种新型肽，旨在增强透皮药物传递。

Transdermal Peptide (TD 1 peptide) acetate is a 11-amino acid peptide, binds toNa+/K+-ATPase beta-subunit (ATP1B1), and mainly interacts with the C-terminus of ATP1B1. Transdermal Peptide can enhance the transdermal delivery of many macromolecules.Transdermal Peptide TD 1 Amide is novel peptide designed to enhance transdermal drug delivery.

In the presence of Transdermal Peptide, because of the specific binding of Transdermal Peptide to ATP1B1, cells will upregulate the level of ATP1B1 to maintain function and structure; as a result, the expression of ATP1B1 increases. However, as time goes on, some Transdermal Peptide molecules may be transported into cells by endocytosis; consequently, the expression of ATP1B1 then decreases. The interaction between Transdermal Peptide and ATP1B1 changes not only the expression of ATP1B1, but also the localization of ATP1B1 and then the structure of the epidermal layer. This interaction can be attenuated by inhibitors or competitors, which would result in the reduced delivery of macromolecular drugs across the skin[1].
