摘要:盐霉素(salinomycin)作为一种离子载体型抗生素,有抑制肿瘤细胞增殖、转移及促凋亡的作用。其特异性杀伤肿瘤干细胞(cancerstemcell,CSC)作用的发现也引起了国内外学者的广泛关注。近年来,有研究发现盐霉素杀死小鼠身上乳腺癌干细胞的能力比普通化疗药高100倍。通过手术及传统化疗药抗癌的方法已经难以对抗肿瘤的高复发与转移,盐霉素这种靶向作用于CSC的能力使得根治肿瘤和防止肿瘤复发和转移在理论上成为可能。多项研究已经证实盐霉素能够对抗多种肿瘤干细胞,该文通过查阅国内外大量文献将系统阐述盐霉素杀伤肿瘤干细胞的作用及其机制,以期为研发抗肿瘤新药提供依据。

Abstract:Salinomycin,a potassium ionophore antibiotic, can suppress the proliferation, metastasis and induce the apoptosis of diverse cancer cells. The specific anti-cancer stem cell(anti-CSC) activity of salinomycin has evoked excitement at home and abroad.In view of recent findings, salinomycin could deplete the proportion of CSCs by>100-fold relative to traditional chemotherapy drugs.The traditional methods of surgery and chemotherapy have proved to be difficult to prevent recurrence of metastasis of tumor.Fortunately,it is possible in theory to cure cancer radically and prevent recurrence of metastasis of tumor by specifically killing targeted tumor stem cells. Many studies have confirmed that salinomycin can fight against a variety of cancer stem cells. Through consulting a large number of literature at home and abroad, this paper systematically reviewed the role of the anti-CSCs activity and its possible antitumor mechanism of salinomycin, in order to provide the basis for developing anti-tumor drugs.

盐霉素(Salinomycin,SAL)又名沙利霉素,属于新一代的离子型促生长剂,也是一种离子载体抗生素,是由日本研究者于1968年从白色链霉菌中提取的一种羧基聚醚类型化合物[1],它能中和细胞中的阳离子,对大多数革兰氏阳性菌及各种球虫有较好的抑制和杀伤作用[2-4]。2009年,美国的研究人员Gupta等[5]对16000种化合物进行检测发现盐霉素能杀死乳腺癌干细胞,且杀死的能力较普通化疗药紫杉醇高出100倍。2……
