structure–activity relationships (SARs) of 19 andrographolide analogues which were synthesized by modification at the three hydroxyl groups. A number of the andrographolide analogues showed much higher cytotoxic activities than that of the parent compound on cancer cells including P-388, KB, COL-2, MCF-7, LU-1 and ASK cells. SAR studies of the synthetic analogues indicated that the introduction of silyl ether or
穿心莲内酯是穿心莲的主要二萜类内酯,对癌细胞有毒性。在本研究中,我们研究了19种穿心莲内酯类似物的结构-活性关系(SAR),它们通过在三个羟基上的修饰合成。许多穿心莲内酯类似物对癌细胞的细胞毒性活性比母体化合物高得多,包括P-388,KB,COL-2,MCF-7,LU-1和ASK细胞。合成类似物的SAR研究表明,将甲硅烷基醚或三苯基甲基醚基团引入母体化合物的C-19中会导致对癌细胞的毒性增加。19- O-三苯甲基醚类似物18 与有效的抗癌药玫瑰树碱相比,它显示出更高的细胞毒活性,该类似物可能是潜在的潜在结构导致开发新的抗癌药。
