A novel series of 5-(ω-aryloxyalkyl)oxazole derivatives was prepared and their effects on brain-derived neurotrophic factor (BDNF) production were evaluated in human neuroblastoma (SK-N-SH) cells. Syntheses were performed by construction of an oxazole ring as a key reaction. Most of the 5-(ω-aryloxyalkyl)oxazole derivatives markedly increased BDNF production in SK-N-SH cells. 4-(4-Chlorophenyl)-2-(2-methyl-1H-imidazol-1-yl)-5-[3-(2-methoxyphenoxy)propyl]-1, 3-oxazole, one of the most promising compounds, showed potent activity (EC50=7.9 μM) and the improvement of the motor nerve conduction velocity and the tail-flick response accompanied by a recovery of the brain-derived neurotrophic factor level in the sciatic nerve of streptozotocin (STZ)-diabetic rats.
一系列新颖的5-(ω-芳氧基烷基)噁唑衍生物被制备出来,并在人神经母细胞瘤(SK-N-SH)细胞中评估了它们对脑源性神经营养因子(BDNF)产生的影响。合成过程通过构建噁唑环作为关键反应来完成。大部分5-(ω-芳氧基烷基)噁唑衍生物显著增加了SK-N-SH细胞中的BDNF产量。其中一种非常有前景的化合物,即4-(4-氯苯基)-2-(2-甲基-1H-咪唑-1-基)-5-[3-(2-甲氧基苯氧基)丙基]-1,3-噁唑,显示了强大的活性(EC50=7.9微摩尔),并且伴随脑源性神经营养因子水平在链脲佐菌素(STZ)诱导的糖尿病大鼠坐骨神经中的恢复,改善了运动神经传导速度和尾部拍打反应。
