Hybrids of fibronectin-related peptides [Arg-Gly-Asp (RGD), Arg-Gly-Asp-Ser (RGDS)] and poly(ethylene glycol) (PEG) were prepared and their inhibitory effects on experimental metastasis in mice were examined. The inhibitory effect of RGD was markedly potentiated by hybrid formation with poly(ethylene glycol) #6000. As to inhibitory effect, RGD was more potent than RGDS and RGD PEG hybrids were superior to RGDS PEG hybrids. Hybrid formation with PEG #6000 was more effective than that with PEG #4000.
制备了纤连蛋白相关肽[精氨酸-甘氨酸-天冬氨酸（RGD）、精氨酸-甘氨酸-天冬氨酸-丝氨酸（RGDS）]与聚乙二醇（PEG）的杂化物，并检测了它们对小鼠实验性转移的抑制作用。通过与聚乙二醇#6000形成杂化物，RGD的抑制作用显著增强。就抑制作用而言，RGD比RGDS更有效，且RGD-PEG杂化物优于RGDS-PEG杂化物。与聚乙二醇#6000形成杂化物比与聚乙二醇#4000更有效。
