  Combating P-glycoprotein-mediated multidrug resistance with 10- O -phenyl dihydroartemisinin ethers in MCF-7 cells

  摘要：

  A series of 10-beta-phenyl ethers of dihydroartemisinin (DHA) with piperazine substitutions were synthesized with the goal of overcoming multidrug resistance in cancer therapy. These novel compounds exerted significant antiproliferative activities in breast cancer MCF-7 and MCF-7/Adr cell lines at the submicromolar level and were shown to be approximately 100- to 300-times more potent than the lead compound DHA. Remarkably, the P-gp-overexpressed MCF-7/Adr cell line showed collateral sensitivity towards these derivatives. Furthermore, compounds 3d and 5c, with the highest selectivity for MCF-7/Adr towards MCF-7 cells, were free from P-gp efflux in a MDCK-MDR1 assay. Flow cytometry and western blot assays suggested that the antiproliferative effects of 5c were associated with cell cycle arrest at G1 phase through the downregulation of Cyclin D1 and Cyclin B1.
