A group of 4-(benzyloxy)-1-phenylbut-2-yn-1-ol derivatives were designed using Site point connection method, synthesized and evaluated for their 5-Lipoxygenase (5-LOX) inhibitory activity. Hydrophobic site points in 5-LOX were considered for the study and substitutions were planned such that 4k will have strong hydrophobic group in the corresponding site point. Biological results supported the in silico
使用定点连接方法设计了一组4-(苄氧基)-1-苯基丁-2-yn-1-ol衍生物,合成并评估了其对5-脂氧合酶(5-LOX)的抑制活性。本研究考虑了5-LOX中的疏水位点,并计划了替代,以使4k在相应的位点具有强疏水基团。生物学结果支持了化合物4k的计算机模拟预测,该化合物对5-LOX的IC 50值为8μM,具有良好的抑制作用。化合物4j和4k对多种癌细胞系(COLO-205,MDA-MB-231和HepG2)显示出有效的细胞毒性作用,但对正常细胞系(HaCaT)无作用。总体趋势显示4k是最有效的化合物。进一步的研究证明了4k在脂多糖(LPS)诱导的小鼠急性肺损伤(ALI)模型中的保护作用。
