(2R,3Z)-, (2R,3E)-, (2S,3Z) and (2S,3E)-2-Acetylamino-3-octadecen-1-ol, and (2R)- and (2S)-2-acetylamino-octadecan-1-ol were prepared using the Wittig olefination of Garner's aldehyde (N-Boc-N,O-isopropylidene-L- or D-serinal) from L- or D-serine. The apoptotic activities of these saturated and unsaturated 2-acetylaminoalcohols were examined in human leukemia HL-60 cells using MTT assay. Among the newly synthesized compounds, the cis-isomers were the most potent. Despite their simple structures, (2R,3Z)- and (2S,3Z)-2-acetylamino-3-octadecen-1-ol showed high and comparable apoptotic activities compared with N-acetyl-D-erythro-sphingosine (D-e-C2-Cer, a well-known inducer of apoptosis). Their apoptotic activities were in the order D-e-C2-Cer≈L-e-C2-Cer≈(2R,3Z)-≈(2S,3Z)-?(2R,3E)-≈(2S,3E)-≈(2R) -≈(2S)-derivative. Qualitative analysis of DNA fragmentation caused by these compounds was conducted using agarose gel electrophoresis, and typical DNA fragmentation was found in the cases of (2R,3Z)- and (2S,3Z)-isomers such as C2-Cer, but not trans and saturated isomers. The morphological features of the cells, the proteolytic processing of pro-caspase-3, and the cleavage of PARP as a result of exogenous treatment with (2R,3Z)- and (2S,3Z)-isomers indicated that cell death induced by these compounds was apoptosis. These observations suggest that these newly synthesized compounds, (3Z)-2-Acetylamino-3-octadecen- 1-ol, have similar characteristics and apoptosis-inducing activities against HL-60 cells with C2-Cer.
