A novel series of compounds obtained by fusing the metal-chelating agent clioquinol and the antioxidant ebselen were designed, synthesized and evaluated as multi-target-directedligands against Alzheimer's disease (AD). Specifically, compared with their parent compounds clioquinol and ebselen, these hybrids demonstrated significant potency in inhibiting self- and Cu(II)-induced amyloid-β (Aβ) aggregation
设计,合成和评估了通过将金属螯合剂氯喹醇和抗氧化剂依布硒啉融合而获得的一系列新型化合物,这些化合物可作为针对阿尔茨海默氏病(AD)的多靶标配体。具体而言,与它们的母体化合物喹喔啉和依伯硒仑相比,这些杂种显示出显着的抑制自我和Cu(II)诱导的淀粉样β(Aβ)聚集的能力,并充当了杰出的抗氧化剂和生物金属螯合剂。此外,该杂种在依布硒啉相关的药理特性方面显示出显着改善,包括模仿谷胱甘肽过氧化物酶和清除H 2 O 2的能力。在这些分子中,化合物10h被确定为AD治疗的潜在先导化合物。重要的是,发现该化合物具有快速的H 2 O 2清除活性和谷胱甘肽过氧化物酶样(GPx样)活性。此外,化合物10h能够有效地分解预制的自我和Cu(II)诱导的Aβ聚集体。此外,在高达2000 mg kg -1的剂量下,10h能够穿透中枢神经系统(CNS),并且在小鼠中没有表现出任何急性毒性。

investigation its mechanism of action, we designed and synthesized its biotinylated derivative 2 as a novel probe. From commercially available starting material, 2 was obtained in 6 steps with 13.4% overall yield. It is notable that this practical synthetic route give a template for the preparation of unsymmetrical di-benzo[d][1,2]selenazol-3(2H)-ones. Based on probe 2, we developed a novel biomolecular
Hexylselen是一种新型的亚微摩尔双KGA / GDH抑制剂,可有效抑制癌细胞,并具有最小的毒性。为了进一步研究其作用机理,我们设计并合成了其生物素化衍生物2作为新型探针。从市售原料中,经6个步骤得到2个,总收率为13.4%。值得注意的是,该实用的合成途径为制备不对称的二苯并[ d ] [1,2]硒烯唑-3(2 H)-酮提供了模板。基于探针2,我们开发了一种新颖的生物分子相互作用测定法,用于方便,可靠地测试KGA变构抑制剂,并通过竞争性实验证实,己基硒醚作为KGA的变构抑制剂,与BPTES具有相同的结合口袋,而与Ebselen没有相同的结合口袋。
