Chemistry researchers at Oregon State University have patented a method for making anti-leukemia compounds that until now have only been available via an Asian tree that produces them.

The synthesis of cephalotaxine and homoharringtonine (HHT) paves the way toward less-expensive, more readily available leukemia drugs whose production is not subject to the risks and inefficiencies associated with harvesting natural sources.

Also, the synthesis of cephalotaxine opens the door to preparing other, structurally related compounds for evaluation as potential new cancer drugs.
