Laminin-related peptides, Tyr-Ile-Gly-Ser-Arg analogs, were prepared and their inhibitory effects on experimental metastasis were examined. Of the amino acids in the Tyr-Ile-Gly-Ser-Arg sequence, L-Arg was very important and Ile was not essential for the inhibitory effect. To obtain a potent inhibitor of metastasis, hybrids of Tyr-Ile-Gly-Ser-Arg-Gly and 2 types of poly(ethylene glycol) were prepared. The inhibitory effects of the hybrids were more potent than that of Tyr-Ile-Gly-Ser-Arg-Gly.
制备了层粘连蛋白相关肽，即酪氨酸 - 异亮氨酸 - 甘氨酸 - 丝氨酸 - 精氨酸类似物，并检测了它们对实验性转移的抑制作用。在酪氨酸 - 异亮氨酸 - 甘氨酸 - 丝氨酸 - 精氨酸序列中的氨基酸中，L - 精氨酸非常重要，而异亮氨酸对抑制作用并非必不可少。为了获得一种有效的转移抑制剂，制备了酪氨酸 - 异亮氨酸 - 甘氨酸 - 丝氨酸 - 精氨酸 - 甘氨酸与两种聚乙二醇的杂化物。这些杂化物的抑制作用比酪氨酸 - 异亮氨酸 - 甘氨酸 - 丝氨酸 - 精氨酸 - 甘氨酸更强。
