A series of fatty acid amides were synthesized and their peroxisome proliferator-activated receptor α (PPAR-α) agonistic activities were evaluated in a normal rat liver cell line, clone 9. The mRNAs of the PPAR-α downstream genes, carnitine-palmitoyltransferase-1 and mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase, were determined by real-time reverse transcription-polymerase chain reaction (RT-PCR) as PPAR-α agonistic activities. We prepared nine oleic acid amides. Their PPAR-α agonistic activities were, in decreasing order, N-oleoylhistamine (OLHA), N-oleoylglycine, Oleamide, N-oleoyltyramine, N-oleoylsertonin, and Olvanil. The highest activity was found with OLHA. We prepared and evaluated nine N-acylhistamines (N-acyl-HAs). Of these, OLHA, C16:0-HA, and C18:1Δ9-trans-HA showed similar activity. Activity due to the different chain length of the saturated fatty acid peaked at C16:0-HA. The PPAR-α antagonist, GW6471, inhibited the induction of the PPAR-α downstream genes by OLHA and N-oleoylethanolamide (OEA). These data suggest that N-acyl-HAs could be considered new PPAR-α agonists.
合成了一系列脂肪酸酰胺,并评估了它们在正常大鼠肝细胞系clone 9中对过氧化物酶体增殖物激活剂受体α(PPAR-α)的激动活性。通过实时反转录聚合酶链反应(RT-PCR)测定了PPAR-α下游基因肉碱棕榈酰转移酶-1和线粒体3-羟基-3-甲基戊二酰辅酶A合酶的mRNA,作为PPAR-α激动活性的指标。我们合成了九种油酸酰胺。它们的PPAR-α激动活性按递减顺序为N-油酸组胺(OLHA)、N-油酸甘氨酸、油酰胺、N-油酸酪胺、N-油酸血清素和Olvanil。最高活性出现在OLHA。我们还合成并评估了九种N-酰基组胺(N-acyl-HAs)。其中,OLHA、C16:0-HA和C18:1Δ9-trans-HA显示出相似的活性。由于饱和脂肪酸不同链长的活性在C16:0-HA处达到峰值。PPAR-α拮抗剂GW6471抑制了OLHA和N-油酸乙醇酰胺(OEA对PPAR-α下游基因的诱导。这些数据表明N-酰基组胺可以被视为新的PPAR-α激动剂。
