Three compounds were separated from the root of Rhododendron molle G.Don and identified as Rhodojaponin-Ⅲ, taraxerol, β-sitosterol for the first time.展开更多
目的:研究蒲公英萜醇对肺癌细胞糖酵解效应的影响。方法:采用肺癌细胞株H1299,A549检测细胞葡萄糖消耗及乳酸含量及细胞ATP,NAD+/N A D H含量;同时给予血小板衍生生长因子BB(platelet-derived grow th factor BB,PDGF-BB)上调Akt途径促...目的:研究蒲公英萜醇对肺癌细胞糖酵解效应的影响。方法:采用肺癌细胞株H1299,A549检测细胞葡萄糖消耗及乳酸含量及细胞ATP,NAD+/N A D H含量;同时给予血小板衍生生长因子BB(platelet-derived grow th factor BB,PDGF-BB)上调Akt途径促进糖酵解反应,考察蒲公英萜醇对肺癌细胞糖酵解的影响。结果:蒲公英萜醇可明显降低肺癌细胞葡萄糖消耗、乳酸含量及细胞ATP含量,升高NAD+/NADH含量。给予PDGF刺激H1299,A549细胞后细胞葡萄糖消耗及乳酸含量显著升高,细胞ATP含量升高,己糖激酶(hexokinase,HK)活性明显升高,NAD+/NADH含量降低;给予蒲公英萜醇后,可明显降低PDGF-BB诱导的H1299,A549细胞糖酵解水平,抑制HK活性,并抑制Akt磷酸化水平;结论:蒲公英萜醇可抑制肺癌细胞糖酵解水平,抑制HK活性,该作用与调控Akt途径相关。展开更多
