A series of ebselen derivatives were designed, synthesised and evaluated as inhibitors of cholinesterases (ChEs) and glutathione peroxidase (GPx) mimics. Most of the compounds were found to be potent against AChEs and BuChE, compounds 5e and 5i, proved to be the most potent against AChE with IC50 values of 0.76 and 0.46 μM, respectively. Among these hybrids, most of the compounds were found to be good
设计,合成和评估了一系列依布硒仑衍生物,作为胆碱酯酶(ChEs)和谷胱甘肽过氧化物酶(GPx)模拟物的抑制剂。发现大多数化合物对AChE和BuChE均有效,化合物5e和5i被证明对AChE最有效,IC 50值分别为0.76和0.46μM。在这些杂种中,与ebselen相比,发现大多数化合物都是良好的GPx模拟物。所选择的化合物5e和5i还用于确定催化参数和体外过氧化氢清除活性。结果表明化合物5e和5i 可能是治疗AD的优秀多功能药物。
