inhibitors of the BfrB–Bfd protein–protein interaction. The process was initiated by screening a fragment library and followed by obtaining the structure of a fragment hit bound to BfrB. The structural insights were used to develop a series of 4-(benzylamino)- and 4-((3-phenylpropyl)amino)-isoindoline-1,3-dione analogs that selectively bind BfrB at the Bfd binding site. Challenging P. aeruginosa cells with
Specific bradycardic agents. 1. Chemistry, pharmacology, and structure-activity relationships of substituted benzazepinones, a new class of compounds exerting antiischemic properties
phthalmidine moiety. This has resulted in a second generation of specificbradycardicagents with increased potency and selectively and prolonged duration of action represented by the benzazepinone-derivative UL-FS 49 (4). Structure-activityrelationships within this novel class of compounds have revealed a marked dependence of activity on the substitution pattern of the aromatic rings, the nature of the central
underlying causes of Alzheimer'sdisease (AD) remain a mystery, with multiple pathological components, including oxidative stress, acetylcholinesterase, amyloid-β, and metal ions, all playing a role. Here we report a strategic approach to designing flavonoids that can effectively tackle multiple pathological elements involved in AD. Our systematic investigations revealed key structuralfeatures for flavonoids
阿尔茨海默病 (AD) 的根本原因仍然是个谜,多种病理成分,包括氧化应激、乙酰胆碱酯酶、β 淀粉样蛋白和金属离子,都发挥了作用。在这里,我们报告了一种设计黄酮类化合物的战略方法,可以有效地解决 AD 中涉及的多种病理因素。我们的系统研究揭示了类黄酮同时靶向和调节致病靶点的关键结构特征。基于完整的结构-活性关系分析,我们的研究结果导致开发出一种极具前景的黄酮类化合物,该类黄酮具有一系列功能。此外,我们的机理研究证实,这种类黄酮的多功能反应性是由其氧化还原电位和与致病因子的直接相互作用驱动的。这项工作凸显了多靶点黄酮类化合物作为对抗 AD 的新解决方案的潜力。
