In vitro 秦岭绞股蓝(Gynostemma pentaphyllum (Thunb.) Makino)作为众所周知的中国传统草药之一,已被证实能有效对抗诸如肺癌等慢性疾病。本研究从原始的、经过热处理的以及碱性水解处理过的秦岭绞股蓝中分离出七种达马烷型化合物,并利用MTT细胞毒性测定法比较它们对非小细胞肺癌A549细胞的细胞毒性活性。方法与结果:通过化学和光谱学方法,确定了这些化合物的结构,包括gypenoside LVI、Gypenoside XLVI、gypenoside L、gypenoside LI、damulin A、damulin B 和20S-dammar-24-en-2α,3β,12β,20-tetrol。这些化合物对A549细胞显示出强烈的细胞毒性活性,其半抑制浓度(IC50)分别为105.89±2.48、52.63±8.31、34.94±4.23、50.96±9.55、26.98±0.51、4.56±0.58、12.54±0.53 μg/ml,而阳性对照物20S-Rg3的IC50值为55.36±3.20 μg/ml。通过比较它们的结构与细胞毒性活性,这些化合物可能具有某种结构-活性关系。结论:基于这七种成分的结构和细胞毒性活性关系,C-2位的羟基、C20(21)和C20(22)位置的双键、糖的连接数目以及C-20的构型对其对A549细胞的细胞毒性活性十分重要。
