The synthesis of a new series of D-erythro-homoceramide analogues is described. Several synthetic approaches were investigated. Homoceramides can be successfully synthesized from L-homoserine as chiral building block and a protected Weinreb-amide as a key intermediate. The synthesis of short-chain analogues with a heptyl side chain, as well as with a phenyl residue in the sphingoid part (instead of
描述了一系列新的D-赤型-高同酰胺酰胺类似物的合成。研究了几种综合方法。可以从L-高丝氨酸中成功合成同质神经酰胺作为手性结构单元,并从保护的Weinreb-酰胺中获得关键的中间体。进行了具有庚基侧链以及鞘氨醇部分中的苯基残基(而不是天然存在的十三烷基侧链)的短链类似物的合成。研究了均神经酰胺15-17和24逆转伏马菌素B(1)对轴突生长的抑制作用的潜力。不幸的是,由于缺乏对葡糖基高酰胺的新陈代谢,所测试的化合物均未显示出任何生物活性。
