then in vitro antiwrinkle activity and transdermal delivery were compared between GHK and GHK‐R4. Notably, Arg4 conjugation accelerated the cellular penetration of GHK both in vitro and in vivo. Furthermore, higher in vitro antiwrinkle activity and collagen biosynthesis was obtained with GHK‐R4 at much lower doses than with control R4‐free GHK. The enhanced activity and delivery of GHK‐R4 might be due
GHK(Gly-His-Lys)是一种在人体皮肤和血浆中发现的天然肽,已广泛用于药妆和制药领域。亲水性的GHK和GHK-Cu渗透到皮肤的能力有限;因此,已经开发出各种用于皮肤递送的策略。在这项研究中,将Arg 4与GHK偶联以获得七肽GHK-R4,然后比较GHK和GHK-R4的体外抗皱活性和透皮递送。值得注意的是,Arg 4缀合加速了GHK在体外和体内的细胞渗透。此外,与不含R4的对照GHK相比,GHK‐R4的剂量具有更低的体外抗皱活性和胶原生物合成。GHK-R4的活性和递送增强可能归因于R4本身的细胞穿透能力和基质金属蛋白酶(MMP)抑制活性。
