toxicity. With the new analogues synthesized in this study, the role of the phenolic moiety, ester function, and bioisosterism was investigated. Several of the 34 compounds inhibited the biosynthesis of 5-LO products, and 20 compounds were 2–11 times more potent than zileuton in PMNL, which are important producers of 5-LO products. Compounds 5i (IC50: 0.20 μM), 5l (IC50: 0.20 μM), and 5o (IC50: 0.21 μM)
芥子酸存在于许多可食用植物和水果中,例如油菜籽,它是主要的酚类化合物。合成并筛选了新的芥子酸苯乙酯 (SAPE) 类似物作为受刺激的 HEK293 细胞和多形核白细胞 (PMNL) 中 5-脂氧合酶 (5-LO) 生物合成的抑制剂。抑制 5-LO 催化的白三烯生物合成是针对某些炎症性疾病和过敏症的有效治疗策略。不幸的是,迄今为止唯一获批的抑制剂由于其药代动力学特征和肝毒性较差,临床应用有限。利用本研究中合成的新类似物,研究了酚部分、酯功能和生物等排性的作用。34 种化合物中有几种抑制 5-LO 产物的生物合成,在 PMNL 中,20 种化合物的效力是齐留通的 2-11 倍,后者是 5-LO 产品的重要生产商。化合物在苯乙基部分的间位带有 4-三氟甲基、甲基或甲氧基取代基的5i (IC 50 : 0.20 μM)、5l (IC 50 : 0.20 μM) 和5o (IC 50 : 0.21 μM)
