阿尔茨海默病(AD)是一种严重的多因素神经退行性疾病,其特征是大脑中神经元的进行性丧失。尽管进行了很多研究,但 AD 进展的发病机制和机制尚未完全清楚。只有少数药物被批准用于治疗 AD。 AD 的多因素特征表明,开发能够针对与该疾病相关的多种病理机制的分子非常重要。因此,在全球公认的多功能配体治疗兴趣的背景下,我们在此报告了一组五种( 1a - e )新型阿魏酸杂化化合物(即阿魏酰基-苄氧基酰胺衍生物)的合成、表征、理化和生物学评估包含不同的取代基,作为潜在的抗阿尔茨海默氏病药物。这些杂化物可以保留天然阿魏酸支架的自由基清除活性和金属螯合能力,还表现出良好/温和的抑制自身Aβ聚集的能力以及相当好的抑制Cu诱导的Aβ聚集的能力。与已知的口服药物相比,预测的药代动力学特性表明吸收良好。

series of novel 12-alkoxyiminothiopentadecanlactones were synthesized starting from 2-nitrocyclododecanone by Michael addition to acrolein, followed by selective reduction of the aldehyde group, conversion of hydroxyl group to mercapto group, ringexpansion, Nef reaction, and finally reaction with alkoxyamines. Their structures were confirmed by 1H NMR, 13C NMR spectra, and mass spectrometry. The Z and E
图形摘要 摘要 以 2-硝基环十二酮为原料,通过迈克尔加成到丙烯醛,然后选择性还原醛基,羟基转化为巯基,扩环,Nef 反应,最后与 2-硝基环十二烷酮反应,合成了一系列新型 12-烷氧基亚氨基硫代十五烷内酯。烷氧基胺。它们的结构经 1H NMR、13C NMR 谱和质谱证实。一些标题化合物的 Z 和 E 异构体通过柱色谱分离,它们的构型通过 1 H NMR 确定。这些化合物对天门冬青霉表现出优异的杀真菌活性,并且优于商业杀真菌剂百菌清。

Novel trifluoromethanesulfonanilide oxime ether compounds useful for controlling endo and/or ectoparasites in the environment are provided, together with methods of making the same, and methods of using the inventive compounds to treat parasite infestations in vivo or ex vivo.
inhibitor has been demonstrated significant clinical benefit for blocking MAPK pathway activation and possibly could block reactivation of the MAPK pathway at the time of BRAF inhibitor resistance. Twenty N-(benzyloxy)-1,3-diphenyl-1H-pyrazole-4-carboxamide derivatives have been designed and synthesized as MEK inhibitors, and their biological activities were evaluated. Among these compounds, compound 7b
attracted attention of researchers owing to their interesting biological properties. Current work details the synthesis of indole containing oxime ether derivatives and their evaluation for antimicrobial activityagainst a panel of bacterial and mycobacterial strains. Synthesized compounds demonstrated good to moderate activityagainst drug-resistant S. aureus including resistant to vancomycin. Among
由多重耐药菌引起的感染已成为对人类健康的持续威胁。尽管目前有多种抗生素可用于治疗传染病,但仍有大量细菌菌株对其中的许多菌株产生了抗药性。其中,金黄色葡萄球菌引起的感染在成人和儿童人群中占主导地位。吲哚是一种突出的化学支架,存在于许多具有药理活性的天然产品和合成药物中。许多含肟醚的化合物由于其有趣的生物学特性而引起了研究人员的关注。目前的工作详细介绍了含吲哚肟醚衍生物的合成及其对一组细菌和分枝杆菌菌株的抗菌活性的评估。合成的化合物对耐药性金黄色葡萄球菌表现出良好到中等的活性,包括对万古霉素的耐药性。其中,发现化合物5h对金黄色葡萄球菌的敏感菌株以及 MRSA 和 VRSA 菌株具有强效活性具有1μMIC克/毫升和2-4μ克/毫升分别。此外,发现化合物5h对 Vero 细胞无毒,并表现出>40 的良好选择性指数。此外,5h、E -9a和E -9b对金黄色葡萄球菌具有良好的生物膜抑制作用。有了这
