Novel antitumor artemisinin derivatives targeting G1 phase of the cell cycle
摘要:
Modification of artemisinin structure led us to the discovery of a novel class of antitumor compounds. These artemisinin derivatives containing cyano and aryl groups showed potent antiproliferative effect in vitro against P388 and A549 cells. This activity was reflected in P388 murine leukemia by an accumulation of cells in G1 phase, and induction of apoptosis. (C) 2000 Elsevier Science Ltd. All rights reserved.
A new type of ether of dihydroartemisinin containing cyano and aryl groups was prepared and tested for cytotoxicity to A549, P388, L1210 and HT29 cells using the MTT assay. 12k and 121 were the most cytotoxic compounds. 13 lacking the peroxy group showed a 1000-fold less potency than 121. Similarly, the inactive compound 14 indicated that the position of cyano groups was also important. Flow cytometry data showed that the compounds caused an accumulation of P388 cells in the G(1)-phase of the cell cycle. (C) 2002 Elsevier Science Ltd. All rights reserved.
