tetrapeptide 5

Tetrapeptide-5 is a humectant or hydroscopic moisturizer.

Acetyl Tetrapeptide-5 acetate helps reduce eye puffiness, improve skin elasticity as well as overall smoothness.

Eyeseryl, also known as Acetyl Tetrapeptide-5, humectant or hydroscopic moisturizer which helps reduce eye puffiness, improve skin elasticity as well as overall smoothness.

H-Arg-Gly-Asp-Cys-OH is a tetrapeptide that contains the arginine-glycine-aspartate (RGD) motif, a sequence that acts as a recognition site for various adhesion proteins.1It inhibits the binding of fibrinogen to endothelial cells and ADP-stimulated platelets with IC50values of 320 and 35 μM, respectively.2Implantation of titanium rods coated with H-Arg-Gly-Asp-Cys-OH increases bone formation in rat femurs.3H-Arg-Gly-Asp-Cys-OH has been conjugated to polyethylenimine to improve gene transfection efficiency.4 1.Park, H.S., Kim, C., and Kang, Y.K.Preferred conformations of RGDX tetrapeptides to inhibit the binding of fibrinogen to plateletsBiopolymers63(5)298-313(2002) 2.Tranqui, L., Andrieux, A., Hudry-Clergeon, G., et al.Differential structural requirements for fibrinogen binding to platelets and to endothelial cellsJ.

Tyr-W-MIF-1, an opioid tetrapeptide, exhibits both opiate and antiopiate activities, and has been demonstrated to induce analgesia [1] [2] [5].

Caprooyl-tetrapeptide-3 acetate, employed for diminishing fine lines and wrinkles, enhances collagen VII and laminin-5 expression in corticoid-induced skin aging models [1].
