Structure-activity studies on the lycorine pharmacophore: A potent inducer of apoptosis in human leukemia cells

Phytochemistry. 2009 May;70(7):913-9. doi: 10.1016/j.phytochem.2009.04.012. Epub 2009 May 20.

Abstract

The direct chemoselective differential functionalization of the ring-C hydroxyl groups present in the Amaryllidaceae alkaloid lycorine is described allowing for selective manipulation of the 1,2-hydroxyl groups. A mini-library comprised of synthetic and natural lycorane alkaloids was prepared and their apoptosis-inducing activity investigated in human leukemia (Jurkat) cells. Further insights into the nature of this interesting apoptosis-inducing pharmacophore are described, including the requirement of both free hydroxyl groups in ring-C.
