摘　　要：近年来,青蒿素类化合物抗肿瘤活性受到越来越多的关注,对人急性早幼粒白血病细胞HL-60、小鼠白血病细胞P388、人乳腺癌细胞MCF-7等肿瘤细胞都表现出较好的抑制作用。本文设计并合成16个新型10-O-氮杂环取代二氢青蒿素类化合物,采用细胞计数法和MTT法测试所合成化合物对人急性早幼粒白血病细胞HL-60、人乳腺癌细胞MCF-7及耐多柔比星细胞MCF-7/Adr的生长抑制活性。药理实验结果表明:在敏感细胞HL-60和MCF-7中,所有目标化合物的生长抑制活性比先导物二氢青蒿素都有所提升,但弱于阳性对照药多柔比星;在耐药细胞MCF-7/Adr中,所有目标化合物表现出强于在敏感细胞MCF-7的生长抑制作用,其GI50值显著低于二氢青蒿素和多柔比星;化合物GF02、GH04、ZH04在3个细胞株中均表现出强烈的生长抑制活性,值得深入研究。Increasing attention has been focused on the antitumor activity of artemisinin derivatives in recent years, for artemisinin had been reported to have cytotoxic effects against HL-60, P388 and MCF-7 tumor cells. We report here the synthesis and evaluation for antitumor activity of a series of artemisinin-ether derivatives bearing tetrahydropyrrole, morpholine, piperidine, substituted piperidines and azoles with various linkers. Sixteen 10-O-substituted dihydroartemisinin derivatives were designed and synthesized, all of which have never been reported in literatures and whose antiproliferative effects on human breast cancer MCF-7, MCF-7/Adr and HL-60 cells were determined by MTT assay or direct cell counting. Each of these artemisinin derivatives possessed better effects than dihydroartemisinin evidently against HL-60 and MCF-7 cells growth, while less potent than doxorubicin. All target compounds exhibited significantly improved potency compared to DHA and doxorubicin on the doxorubicin-resistant MCF-7/Adr cells, so did they in their sensitive counterparts MCF-7 cells. Among them, compounds GF02, GH04 and ZH04 showed strong activity against these three cell lines growth. Further research is undergoing.
