The synthesis of novel N-acylethanolamines and their use as inhibitors of the aCDase is reported here. The compounds are either 2-oxooctanamides or oleamides of sphingosine analogs featuring a 3-hydroxy-4,5-hexadecenyl tail replaced by ether or thioether moieties. It appears that, within the 2-oxooctanamide family, the C3-OH group of the sphingosine molecule is required for inhibition both in vitro
本文报道了新型N-酰基乙醇胺的合成及其作为αCDase抑制剂的用途。所述化合物是具有3-羟基-4,5-十六碳烯基尾部被醚或硫醚部分取代的鞘氨醇类似物的2-氧代辛酰胺或油酰胺。看来,在2-氧代己酰胺家族中,鞘氨醇分子的C3-OH基团对于在体外和在培养的细胞中抑制都是必需的。此外,尽管(E)-4双键对于抑制活性不是必需的,但是(E)构型是必需的,因为具有(Z)-4不饱和度的类似物不是抑制性的。在体外,没有一种油酰胺抑制aCDase。相反,除了N-油酰基乙醇胺及其类似物具有S-癸基和S-十六烷基取代基外,所有合成的油酰胺均抑制培养细胞中的aCDase,尽管效能相对较低。我们得出的结论是,新型aCDase抑制剂可从电子缺陷型酰基鞘氨醇碱基的N-酰化反应中演变而来。相反,N-油酰基鞘氨醇主链的化学修饰似乎没有提供获得aCDase抑制剂的适当策略。
