title: Remarkably enhanced inhibitory effects of three-component hybrid liposomes including sugar surfactants on the growth of lung carcinoma cells.
abstract: 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.
