  Multitarget-Directed Benzylideneindanone Derivatives: Anti-β-Amyloid (Aβ) Aggregation, Antioxidant, Metal Chelation, and Monoamine Oxidase B (MAO-B) Inhibition Properties against Alzheimer’s Disease

  摘要：

  A novel series of benzylideneindanone derivatives were designed, synthesized, and evaluated as multitarget-directed ligands against Alzheimer's disease. The in vitro studies showed that most of the molecules exhibited a significant ability to inhibit self-induced beta-amyloid (A beta(1-42)) aggregation (10.5-80.1%, 20 mu M) and MAO-B activity (IC50 of 7.5-40.5 mu M), to act as potential antioxidants (ORAC-FL value of 2.75-9.37), and to function as metal chelators. In particular, compound 41 had the greatest ability to inhibit A beta(1-42) aggregation (80.1%), and MAO-B (IC50 = 7.5 mu M) was also an excellent antioxidant and metal chelator. Moreover, it is capable of inhibiting Cu(II)-induced A beta(1-42) aggregation and disassembling the well-structured A beta fibrils. These results indicated that compound 41 is an excellent multifunctional agent for the treatment of AD.

  influence the level of cyclic diguanylate (c-di-GMP), a universal secondary messenger that plays an important role in biofilm formation in bacteria. Based on our previous finding that c-di-GMP G-quadruplex inducers are effective biofilm formation inhibitors, we designed and synthesized a c-di-GMP G-quadruplex inducer-NO donor conjugate (A11@NO) as a bifunctional antibiofilm agent after obtaining the c-di-GMP

  生物膜形成引起的抗生素耐药性是一个临床挑战。一氧化氮（NO）可以有效地分散成熟的生物膜，还可以协同影响环二鸟苷酸（c-di-GMP）的水平，环二鸟苷酸是一种通用的第二信使，在细菌生物膜的形成中发挥着重要作用。基于我们之前发现c-di-GMP G-四联体诱导剂是有效的生物膜形成抑制剂，我们设计并合成了c-di-GMP G-四联体诱导剂-NO供体缀合物（A11@NO）作为双功能抗生物膜剂。获得c-di-GMP G-四联体诱导剂( A11 )，其具有能够与亚硝基(NO供体)结合的氨基。缀合物A11@NO表现出比A11更好的生物膜抑制效率，并且还可以根除成熟的生物膜。此外，它对铜绿假单胞菌表现出良好的抗菌协同作用，有助于提高妥布霉素对生物膜形成细菌的杀菌效率。与妥布霉素联合使用，A11@NO还提高了秀丽隐杆线虫在超生物膜环境中的存活率。
