(-)-Cubebin, isolated from the seeds of Piper cubeba, and its five different types of derivatives (a total of 17), with varying functionalities, were tested for their in vitro anticancer activity against six human cancer cell lines (A549, K562, SiHa, KB, HCT116 and HT29) using MTT assay. Cubebin as well as its derivatives containing lactone and amide groups showed significant anticancer activity. In some of the tested cell lines, the amide derivatives showed higher activity. Morphological analysis indicated that these compounds act through apoptosis mediated pathway of cell death and we expect that these results will pave new paths in the development of novel anticancer agents by the derivatization of (-)-cubebin.

(-)-Cubebin是从Piper cubeba的种子中分离出来的,其五种不同类型的衍生物(总计17种)具有不同的官能团。通过MTT法对这六种化合物在体外对六个人类癌细胞系(A549、K562、SiHa、KB、HCT116 和HT29)的抗肿瘤活性进行了测试。Cubebin及其含有内酯和酰胺基团的衍生物显示出显著的抗肿瘤活性。在某些测试的细胞系中,酰胺衍生物表现出更高的活性。形态学分析表明,这些化合物通过凋亡介导的细胞死亡途径发挥作用,我们预期这些结果将为通过(-)-Cubebin的衍生物开发新型抗肿瘤药物铺平道路。(C) 2016 Elsevier Ltd. 保留所有权利。
