一种基于多奈哌齐的新型多功能剂“(E)-5,6-二甲氧基-2-(4-(4-取代的哌嗪-1-基)亚苄基)-2,3-二氢-1 H-茚满-已经设计并合成了“ 1-ones”作为潜在的抗阿尔茨海默氏病药物。体外研究表明,这些化合物显示出中等至良好的AChE和Aβ聚集抑制活性。这些衍生物还具有令人赞叹的抗氧化活性。在整个系列化合物中,IP-9,IP-13和IP-15是最活跃的多功能剂,并显示出显着的AChE抑制,Aβ分解和抗氧化活性。研究表明IP-13和IP-15表现出比标准药物多奈哌齐更好的AChE抑制活性,IP-9,IP-13和IP-15表现出比姜黄素更好的Aβ聚集抑制活性。这些化合物(IP-9,IP-13和IP-15)成功地减轻了H 2 O 2诱导的SH-SY5Y细胞的氧化应激,并表现出出色的针对H 2 O 2的神经保护活性。以及Aβ以浓度依赖性方式诱导SH-SY5Y细胞的毒性。而且,在细胞毒
Design, synthesis and evaluation of novel indandione derivatives as multifunctional agents with cholinesterase inhibition, anti-β-amyloid aggregation, antioxidant and neuroprotection properties against Alzheimer’s disease
A series of novel 2-(4-(4-substituted piperazin-1-yl)benzylidene)-1H-indene-1,3(2H)-diones were designed, synthesized and appraised as multifunctional anti-Alzheimer agents. In vitro studies of compounds 27–38 showed that these compounds exhibit moderate to excellent AChE, BuChE and Aβ aggregationinhibitoryactivity. Notably, compounds 34 and 38 appeared as most active multifunctional agents in the
A series of novel2-(4-(4-substituted piperazin-1-yl)benzylidene)hydrazinecarboxamide derivatives has been successfully designed and synthesized to evaluate their potential as carbonic anhydrase (CA) inhibitors. The inhibitory potential of synthesized compounds against human CAI and CAII was evaluated. Compounds 3a–n exhibited \(\hbox IC}_50}\) values between \(1.89-}415.1\,\upmu \hbox M}\) against

A series of substituted chromones were synthesized and characterized by spectral data. Some of the synthesized compounds were tested for in-vitro antibacterial, antifungal and antioxidant activity. Two compounds have shown very good antioxidant activity and some of the chromone derivatives have exhibited moderate antibacterial and antifungal activity.
Exquisite 1D Assemblies Arising from Rationally Designed Asymmetric Donor-Acceptor Architectures Exhibiting Aggregation-Induced Emission as a Function of Auxiliary Acceptor Strength
melding piperazine and dicyanovinylene to investigate AIE in an asymmetricdonor–acceptor (D–A) construct of A′–D–π–A‐ topology. The synthetic route has been simplified by using phenylpiperazine as a weak donor (D), dicyanovinylene as an acceptor (A), and pyridyl/pyrimidyl groups (PM2/PM3) as auxiliaryacceptors (A′). It has been established that A′ plays a vital role in triggering AIE in these compounds
