As a TCM, Hedyotis diffusa Willd. has been using to treat malignant tumors, and many studies also showed that the extracts from Hedyotis diffusa Willd. possessed evident antitumor activities. Therefore, we carried out chemical study on Hedyotis diffusa Willd. and investigated the cytotoxicity of the obtained compounds on a panel of eight tumor cell lines. As a result, four new compounds were isolated
作为中药,白花蛇舌草。一直用于治疗恶性肿瘤,许多研究还表明,白花蛇舌草提取物的提取物。具有明显的抗肿瘤活性。因此,我们对白花蛇舌草进行了化学研究。并研究了所得化合物对八种肿瘤细胞系的细胞毒性。结果,从白花蛇舌草中分离出四个新化合物,包括三个Shecaoiridoidside AC(1-3)的鸢尾苷和Shecaocerenoside A(4)的脑苷。另外,还获得了六个已知的虹彩化合物(5-10)。还体外评价了所有化合物对HL-60,HeLa,HCT15,A459,HepG2,PC-3,CNE-2和BCG-823的人肿瘤细胞系的细胞毒性。新化合物3对除Hela外的所有肿瘤细胞系均表现出明显的细胞毒性,IC50值为9.6 µM至62.2 µM,而新化合物4对所有细胞系均表现出中等的细胞毒性,IC50值为33.6 µM至89.3 µM。相比之下,新化合物1和已知化合物9显示出对HCT15,A459
