pathologies. MTDLs that combine neuro-repair properties and block the first steps of neurotoxic cascades could be the so long wanted remedies to treat neurodegenerative diseases (NDs). By linking two privileged scaffolds with well-known activities in ND-targets, the flavonoid and the N,N-dibenzyl(N-methyl)amine (DBMA) fragments, new CNS-permeable flavonoid - DBMA hybrids (1-13) were obtained. They were
多靶标定向配体(MTDLs)的设计是获得有效的复杂病理学药物的有效方法。结合神经修复特性并阻断神经毒性级联反应第一步的MTDL可能是治疗神经退行性疾病(ND)的长期以来一直希望的补救措施。通过将两个具有众所周知的ND目标活性的特权支架,类黄酮和N,N-二苄基(N-甲基)胺(DBMA)片段连接起来,获得了新的CNS渗透性类黄酮-DBMA杂种(1-13)。 。他们在一系列涉及阿尔茨海默氏病(AD)和其他ND的靶标中进行了生物学评估,这些靶标分别是人胆碱酯酶(hAChE / hBuChE),β-分泌酶(hBACE-1),单胺氧化酶(hMAO-A / B),脂氧合酶5(hLOX-5)和sigma受体(σ1R/σ2R)。经过漏斗式筛选后,6 7-二甲氧基色酮-DBMA(6)因其具有神经源性和在hAChE,hLOX-5,hBACE-1和σ1R中具有有趣的MTD谱而突出显示。分子动力学模拟显示杂种6最相
