Non-natural ceramide analogues, C2-homo-ceramide and C2-homo-dihydroceramide, were prepared from l-aspartic acid via l-homo-serine. The apoptotic activities of the synthesized ceramide analogues were examined in HL-60 human leukemia cells. C2-homo-and C2- bishomo-ceramide indicate low but considerable apoptotic activities in comparison with C2- ceramide.
