Design, synthesis and antiproliferative activity in cancer cells of novel dihydropyrazolyl and pyrazolyl artemisinin-phenyl ethers / 中国中药杂志

To explore potent anticancer agent based on artemisinin scaffold, a series of 10--phenyl ethers derivatives containing dihydropyrazolyl or pyrazolyl moiety have been designed and synthesized. Their structures were determined by LC-MS and ¹H-NMR date. Inhibitory effects of the target compounds in human breast cancer MCF-7, MCF/Adr, MDA-MB-231 cells and prostate cell line PC-3 were determined by MTT assay. Those derivatives displayed good antiproliferative activity against the tested cancer cells. Particularly, target compounds exhibited significant cytotoxicity against drug-resistance cells MCF/Adr, which was worthy for further investigation.
