Sugar parts play important roles in recognizing molecules on the cell membranes. We successfully produced sugar-type micellar surfactants, lactonoalkylamide (LacCn), for the first time. Spherical vesicles, three-component hybrid liposomes, were obtained after the sonication of the mixture of L-alpha-dimyristoyl-phosphatidylcholine (DMPC), Tween 20 and LacCn (DMPC:Tween 20:LacCn=65:7:28). It is noteworthy that high inhibitory effects of the three-component hybrid liposomes composed of DMPC, Tween 20, and LacCn (DMPC:Tween 20:LacCn=65:7:28) on the growth of glioma (U251) and lung adenocarcinoma (RERF-LC-OK) cells were attained in vitro without any drug, although no significant inhibitory effects of any individual component (DMPC, Tween 20, LacCn) or the two-component hybrid liposomes of DMPC and Tween 20 on the growth of tumor cells examined were obtained.
糖类部分在识别细胞膜上的分子方面发挥着重要作用。我们首次成功制备了糖型胶束表面活性剂,即内酯烷基酰胺(LacCn)。将L-α-二肉豆蔻酰磷脂酰胆碱(DMPC)、吐温20和LacCn(DMPC:吐温20:LacCn = 65:7:28)的混合物超声处理后,得到了球形囊泡,即三组分混合脂质体。值得注意的是,由DMPC、吐温20和LacCn组成的三组分混合脂质体(DMPC:吐温20:LacCn = 65:7:28)在体外对胶质瘤(U251)和肺腺癌(RERF-LC-OK)细胞的生长具有高抑制作用,且无需任何药物,尽管所检测的任何单个组分(DMPC、吐温20、LacCn)或DMPC与吐温20的双组分混合脂质体对肿瘤细胞生长均未显示出显著抑制作用。
