peroxidation inhibition. The molecular features that govern their bioactivity were explored through in silico docking experiments. The results showed that acidic moieties must be placed in certain distance and orientation in the active site of LOX enzyme in order to productively exhibit inhibitory activity. In addition, the 2-pyrrolidinone template significantly contributes in the inhibitory properties
设计,合成并测试了新型的2-吡咯烷酮衍生物的抗氧化和抗炎活性。评价化合物对LOX的抑制活性。还测试了其中最有效的14d [IC 50 0.08(±0.005)mM]和14e [IC 50 0.0705(±0.003)mM]。化合物14d诱导了对大鼠爪水肿的等电位抑制,这与常用标准吲哚美辛(47%)产生的效果非常接近。化合物14e的LOX抑制活性脂质过氧化抑制百分比的值平行进行,这意味着该LOX抑制活性由脂质过氧化抑制支持。通过计算机对接实验探索了控制其生物活性的分子特征。结果表明,酸性部分必须在LOX酶的活性位点以一定的距离和方向放置,以便有效地发挥抑制活性。另外,2-吡咯烷酮模板对新化合物的抑制特性有显着贡献。
