Modification of artemisinin structure led us to the discovery of a novel cl
ass of antitumor compounds. These artemisinin derivatives containing cyano
and aryl groups showed potent antiproliferative effect in vitro against P38
8 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 El
