In an attempt to develop potent and selective anti-tumor agents, two novel series of artemisinin-chalcone hybrids were designed, synthesized and screened for their antitumor activities against HT-29, A549, MDA-MB-231, HeLa and H460 cell lines in vitro. Nearly all of the tested compounds showed significantly increased anti-tumor activity compared with the corresponding dihydroartemisinin (DHA). Most of the title compounds displayed good selectivity toward HT-29 and HeLa cell lines with IC50 values ranging from 0.09 to 0.85 μM. Among them, the most promising compound 9c (IC50 range of 0.09—0.93 μM) was 10.5- to 70-times more active than DHA (IC50 range of 5.6—15.6 μM) respectively.
为了开发有效且选择性强的抗肿瘤药物,设计、合成并筛选了两类新型青蒿素-查尔酮杂合物,测试其对HT-29、A549、MDA-MB-231、HeLa和H460细胞系的抗肿瘤活性。几乎所有测试的化合物与相应的二氢青蒿素(DHA)相比,均显示出显著增强的抗肿瘤活性。大多数目标化合物对HT-29和HeLa细胞系表现出良好的选择性,IC50值范围为0.09至0.85 μM。其中,最有前景的化合物9c(IC50范围为0.09—0.93 μM)比DHA(IC50范围为5.6—15.6 μM)活性高出10.5至70倍。
