arg-gly-asp-cys

Arg-Gly-Asp-Cys is a binding motif of fibronectin and cell adhesion molecules that can inhibit platelet aggregation and fibrinogen binding.

Arg-Gly-Asp-Cys acetate 抑制血小板聚集和纤维蛋白原结合。 Arg-Gly-Asp-Cys acetate 是纤连蛋白与细胞粘附分子的结合基序。

Arg-Gly-Asp-Cys TFA serves as the binding motif through which fibronectin interacts with cell adhesion molecules. This compound has the ability to hinder platelet aggregation and fibrinogen binding.

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.
