skeletons, respectively, showed potent growth inhibitory activities against both types of cancer cells (IC(50) values: 5.7+/-0.9 to 13.0+/-0.7 microM in the case of HCT 116 cells and 5.2+/-0.7 to 12.3+/-0.9 microM in the case of Hep G2 cells). All hydroxynaphthoquinone derivatives isolated in this study exhibited extremely potent growth inhibitory activities against both types of cancer cells (IC(50) values:
从棕榈大黄(Polygonaceae)的根中分离出七个羟基蒽醌衍生物1-7。合成了两个丙酸酯蒽醌衍生物8和9。从紫草紫薇的根中分离出四种羟基萘醌衍生物13、14、16和21。et Zucc。(Boraginaceae)和三种萘醌衍生物(19、22和23)从大果巨果(Royle)Pauls的根中分离出来。(蔷薇科)。通过MTT分析检查了蒽醌和萘醌衍生物对P-gp表达不足的HCT 116细胞和P-gp过度表达的Hep G2细胞的细胞毒性。在蒽醌衍生物中,分别在蒽醌骨架上具有OH,CH(2)OH和COOH取代基的化合物3-5 对两种类型的癌细胞均显示出有效的生长抑制活性(IC(50)值:HCT 116细胞为5.7 +/- 0.9至13.0 +/- 0.7 microM,而5.2 +/- 0.7至12.3 +/- 0.9 microM对于Hep G2细胞)。在这项研究中分离的所有羟基萘醌衍生物均对
