    • Provided is a polypeptide having anti-tumor activity. The amino acid sequence of the polypeptide is FPGSDRF, X-FPGSDRF, FPGSDRF-Z, or X-FPGSDRF-Z, S being a phosphorylated serine residue, X and Z each being an amino acid residue or an amino acid sequence, X being selected from one of F, (R)9, (R)9-F, 6-aminocaproic acid, 6-aminocaproic acid-F, 6-aminocaproic acid-(R)9, and 6-aminocaproic acid-(R)9-F, and Z being selected from one of A, (G) n-RGD, and A-(G)n-RGD. The polypeptide has no toxicity for normal histocytes. However, when being used with chemicals (such as arsenic trioxide), the polypeptide can increase toxicity for tumor cells. Also provided are uses of the polypeptide for preparing anti-tumor drugs.
    • 提供了具有抗肿瘤活性的多肽。 多肽的氨基酸序列是FPGSDRF,X-FPGSDRF,FPGSDRF-Z或X-FPGSDRF-Z,S是磷酸化丝氨酸残基,X和Z各自是氨基酸残基或氨基酸序列,X被选择 来自F,(R)9,(R)9-F,6-氨基己酸,6-氨基己酸-F,6-氨基己酸 - (R)9和6-氨基己酸 - (R) F和Z选自A,(G)n-RGD和A-(G)n-RGD中的一个。 该多肽对正常组织细胞无毒性。 然而,当与化学品(例如三氧化二砷)一起使用时,多肽可以增加肿瘤细胞的毒性。 还提供多肽用于制备抗肿瘤药物的用途。
