mono- and di-O-prenylated chalcone derivatives were designed on the basis of a homology derived molecular model of 5-lipoxygenase (5-LOX). The compounds were docked into 5-LOX active site and the binding characteristics were quantified using LUDI. To verify our theoretical assumption, the molecules were synthesized and tested for their 5-LOX inhibitory activities. The synthesis was carried out by Claisen–Schmidt
基于5-脂氧合酶(5-LOX)的同源性衍生分子模型,设计了十种新颖的单-和二-O-烯丙基化查尔酮衍生物。将化合物对接至5-LOX活性位点,并使用LUDI定量结合特征。为了验证我们的理论假设,对分子进行了合成并测试了其5-LOX抑制活性。通过单-和二-O-烯丙基化的苯乙酮与适当的醛的克莱森-施密特缩合反应进行合成。5-LOX体外抑制试验显示,二-O-异戊烯化查耳酮的功效比其单-O-异戊烯化查耳酮类似物更高。化合物5e对IC 50表现出良好的抑制作用为4μM。计算的结合能和LUDI得分的总体趋势与实验数据在质量上吻合良好。此外,化合物5e中显示了强的抗增殖作用(GI 50对乳腺癌细胞系在9μM),MCF-7。
