摘要
目的合成鬼臼毒素聚合物胶团,评价其对人胶质瘤细胞的增殖抑制作用。方法制备鬼臼毒素聚合物胶团,考察其理化性质,通过肿瘤细胞摄取实验,噻唑蓝(MTT)法检测其对U87细胞的增殖抑制作用。结果鬼臼毒素聚合物胶团比游离药物鬼臼毒素对人胶质瘤细胞有更大的增殖抑制作用,显著增加肿瘤细胞内的药物浓度。结论鬼臼毒素聚合物胶团对人脑胶质瘤细胞增殖有明显的抑制作用。
OBJECTIVE To investigate the effect of stearic acid grafted chitosan oligosaccharide polymeric micelles loading podophyllotoxin（CSO-SA/PPT） on the cell proliferation in human glioma cells. METHODS CSO-SA/PPT were prepared to investigate its physical and chemical properties. U87 cell proliferative activity was measured by tumor cell uptake assay and MTT assay. RESULTS The CSO-SA/PPT had greater inhibition on human glioma cells proliferation compared with free podophyllotoxin formulation. And in vitro drug uptake tests showed that CSO-SA/PPT presented more uptake characteristics than free podophyllotoxin. CONCLUSION CSO-SA/PPT plays an inhibitory role in the cell proliferation in human glioma cells.
