Usage And Synthesis:

Chemical Properties: Off-white Cryst UsageHomoharringtonine (HHT) combined with some botanical drugs could induce cancer cells to resemble normal cells. HHT was prepared by a semi-synthetic method from Cephalotaxine, a major alkaloid of Cepahlotaxus species through the formation of a-ketoes Biological ActivityInhibitor of protein synthesis. Blocks elongation phase of translation by binding to the 60-S ribosome subunit. Antileukemic. Homoharringtonine
