摘要: 目的:研究超支化聚缩水甘油-羟喜树碱药物递送系统(biodegradable hyperbranched polyglycerol-hydroxy camptothecin, dHPG-HA)对体外培养的人腺样囊性癌(高肺转移)细胞(salivary adenoid cystic carcinoma-lung metastases, SACC-LM)的抑制作用。方法:细胞计数试剂盒(cell counting kit, CCK8)检测药物浓度为0.001、0.01、0.1、1、10、100 μg/mL的羟喜树碱(hydroxy camptothecin, HA)和含等量HA的dHPG-HA,在24、48 h对肿瘤细胞的抑制作用;流式细胞仪检测浓度为0.001、0.01、0.1、1、10 μg/mL的dHPG-HA是否能诱导SACC-LM细胞凋亡。结果:HA和dHPG-HA对SACC-LM细胞增殖均有明显抑制作用,且作用呈剂量依赖性和时间依赖性;dHPG-HA对SACC-LM细胞的细胞毒性明显低于HA;dHPG-HA能诱导SACC-LM细胞凋亡。结论:dHPG的构建能达到使药物HA缓释的作用并降低其细胞毒性。

Abstract: Objective: To investigate the inhibition effects of hyperbranched polyglycidol-hydroxy camptothecin (dHPG-HA) drug delivery system on cultured human adenoid cystic carcinoma (high lung metastasis) cells (SACC-LM). Methods: SACC-LM cells cultured in vitro were treated with different concentrations of hydroxy camptothecin (HA) and (dHPG-HA) which contained equal amounts of HA, and the proliferation inhibition of SACC-LM cells was detected with cell counting kit assay (CCK8). Apoptosis of SACC-LM cells treated by various concentrations of HA and dHPG-HA was ascertained by flow cytometry. Results: The proliferation of SACC-LM cells was significantly reduced. And the effect was dose-dependent and time-dependent. In addition, the cytotoxicity of dHPG-HA on SACC-LM cells was obviously lower than free HA. Furthermore, dHPG-HA could induce apoptosis of SACC-LM cells effectively. In a word, the construction of drug carrier (dHPG) on HA provided sustained release of drugs and reduced its cytotoxicity.

Key words: salivary adenoid cystic carcinoma-lung metastases cell, biodegradable hyperbranched polyglycerol-hydroxy camptothecin, inhibition, apoptosis
