A library of 64 phytosphingolipid analogues resulting from the systematic variation of the C1, C3, C4, and the N-acyl moiety of phytosphingosine (PHS) has been prepared from common scaffolds derived from the chiral pool and Sharpless asymmetric dihydroxylation reactions. Library members have been evaluated as growth inhibitors of the yeast Saccaromyces cerevisiae. In addition, 1-amino-N-pivaloyl PHS analogues were also tested as IPC synthase inhibitors, in comparison with the natural product khafrefungin.
已制备出一个由64种植物鞘氨醇类类似物组成的库,这些类似物是通过系统改变植物鞘氨醇(PHS)的C1、C3、C4和N-酰基基团而获得的,采用了源自手性池和Sharpless不对称二醇化反应的公共骨架。该库的成员作为酵母酿酒酵母(Saccaromyces cerevisiae)的生长抑制剂进行了评估。此外,还测试了1-氨基-N-哌喹酰PHS类似物,作为IPC合成酶抑制剂,并与天然产物khafrefungin进行比较。
