To discover multifunctional agents for the treatment of Alzheimer's disease (AD), a series of chalcone-O-carbamate derivatives was designed and synthesized based on the multitarget-directed ligands strategy. The in vitro biological activities were evaluated including AChE/BChE inhibition, MAO-A/MAO-B inhibition, antioxidant activities, Aβ1-42 aggregation inhibition, metal-chelating properties and neuroprotective
为了发现用于治疗阿尔茨海默氏病(AD)的多功能药物,基于多靶标定向配体策略,设计并合成了一系列查尔酮-O-氨基甲酸酯衍生物。在体外的生物活性进行了评价,包括乙酰胆碱酯酶/抑制的BChE,MAO-A / MAO-B抑制作用,抗氧化活性,Aβ 1-42聚集抑制作用,金属螯合性质和危害ħ神经保护作用2 ö 2诱导的PC12细胞损伤。结果显示化合物5b和5h具有对IC 50的高度选择性BChE抑制活性值分别为3.1μM和1.2μM,并显示出高度选择性的MAO-B抑制能力,IC 50值分别为1.3μM和3.7μM。另外,化合物5b和5h可以抑制自身诱导的Aβ1-42聚集,抑制百分率分别为63.9%和53.1%。特别地,化合物5b是有效的抗氧化剂和神经保护剂,以及通过螯合Cu 2+和Al 3+的选择性金属螯合剂。而且,化合物5b可以抑制和分解Cu 2+诱导的Aβ1-42聚集,这进一步得到了TEM图像的
