A new type of polypeptide containing the repeating sequence of cell attachment site in laminin, poly(Tyr-Ile-Gly-Ser-Arg), was synthesized by the polymerization procedure with diphenylphosphoryl azide (DPPA). We found that this polypeptide inhibited the metastatic formation in the lung of malignant tumour cells far more effectively than pentapeptide.
一种含有层粘连蛋白中细胞附着位点重复序列的新型多肽,聚(酪氨酸 - 异亮氨酸 - 甘氨酸 - 丝氨酸 - 精氨酸),通过用二苯基磷酰叠氮化物(DPPA)的聚合程序合成。我们发现这种多肽比五肽更有效地抑制恶性肿瘤细胞在肺中的转移形成。
