The biological activity of synthetic ceramide analogues, having modified sphingoid and N-acyl chains, as well as fluorine substituents in the allylic position, was investigated in hippocampal neurons. Their influence on axonal growth was compared to that of C(6)-N-acyl analogues of natural ceramides. D-erythro-Ceramides with a phenyl group in the sphingoid moiety and a short N-acyl chain were able
在海马神经元中研究了合成的神经酰胺类似物的生物活性,该神经酰胺类似物具有修饰的类神经鞘和N-酰基链以及在烯丙基位置的氟取代基。他们对轴突生长的影响与天然神经酰胺的C(6)-N-酰基类似物进行了比较。在鞘氨醇部分具有苯基且N-酰基链短的D-赤型神经酰胺能够逆转伏马菌素B(1)(FB(1))的抑制作用,但不能逆转D-threo-1-苯基的抑制作用-2-癸酰基氨基-3-吗啉代-1-丙醇(PDMP)对海马神经元轴突生长的促进作用。此外,我们证明了鞘氨醇部分中具有芳香环的神经酰胺类似物被葡糖神经酰胺合酶识别为底物,这表明观察到的生物学效应是通过糖基化激活神经酰胺类似物介导的。在鞘氨醇部分的苯环的对位引入甲基,戊基,氟或甲氧基取代基产生部分活性的化合物。同样,用苯环取代噻吩基并不能消除逆转FB(1)对轴突生长的抑制作用。具有烯丙基氟取代基的D-赤型和L-苏型神经酰胺类似物均部分逆转了FB(1)的抑制作
