  based on a two-step derivatization to 2-N-naphthimide- 1,3,4-O-trinaphthoate derivatives which gives rise to unique exciton coupled circular dichroic and 1H-NMR spectra in selected solvents. The spectra can be used as reference data for assignment of relative as well as absolute configurations of phytosphingosine isomers and congeners at the low-nanomole level.

  通过使用Wittig和Julia烯化反应，然后进行Sharpless二羟基化反应，已轻松合成了植物鞘氨醇的8种构型异构体中的4种。这四种立体异构体的集合用作模型化合物，用于开发用于分配所有植物鞘氨醇异构体的相对和绝对构型的通用化学/ CD / NMR方案。该程序基于两步衍生化为2- N-萘酰亚胺-1,3,4 - O-叔萘甲酸酯衍生物，这在选定的溶剂中产生了独特的激子耦合的圆二色性光谱和1 H-NMR光谱。光谱可用作参考数据，用于分配低鞘氨醇水平的植物鞘氨醇异构体和同类物的相对和绝对构型。

  (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-serme. 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-Cerapproximate toL-e-C2-Cerapproximate to(2R,3Z)-approximate to(2S,3Z)- > > (2R,3E)-approximate to(2S,3E)-approximate to(2R)-approximate to(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.

• Pachastrissamine (jaspine B) and its stereoisomers inhibit sphingosine kinases and atypical protein kinase C
  作者：Yuji Yoshimitsu、Shinya Oishi、Jun Miyagaki、Shinsuke Inuki、Hiroaki Ohno、Nobutaka Fujii

  Sphingosine kinases (SphKs) are oncogenic enzymes that regulate the critical balance between ceramide and sphingosine-1-phosphate. Much effort has been dedicated to develop inhibitors against these enzymes. Naturally occurring pachastrissamine (jaspine B) and all its stereoisomers were prepared and evaluated for their inhibitory effects against SphKs. All eight stereoisomers exhibited moderate to potent inhibitory activity against SphK1 and SphK2. Inhibitory effects were profiled against protein kinase C (PKC) isoforms by in vitro experiments. Atypical PKCs (PKC zeta and PKC iota) were inhibited by several pachastrissamine stereoisomers. The improved activity over N,N-dimethylsphingosine suggests that the cyclic scaffold in pachastrissamines facilitates potential favorable interactions with SphKs and PKCs. (C) 2011 Elsevier Ltd.
