  Functionalized acridin-9-yl phenylamines protected neuronal HT22 cells from glutamate-induced cell death by reducing intracellular levels of free radical species

  摘要：

  The in vitro neuronal cell death model based on the HT22 mouse hippocampal cell model is a convenient means of identifying compounds that protect against oxidative glutamate toxicity which plays a role in the development of certain neurodegenerative diseases. Functionalized acridin-9-yl-phenylamines were found to protect HT22 cells from glutamate challenge at submicromolar concentrations. The Aryl(1)-NH-Aryl(2) scaffold that is embedded in these compounds was the minimal pharmacophore for activity. Mechanistically, protection against the endogenous oxidative stress generated by glutamate did not involve up-regulation of glutathione levels but attenuation of the late stage increases in mitochondrial ROS and intracellular calcium levels. The NH residue in the pharmacophore played a crucial role in this regard as seen from the loss of neuroprotection when it was structurally modified or replaced. That the same NH was essential for radical scavenging in cell-free and cell-based systems pointed to an antioxidant basis for the neuroprotective activities of these compounds. (C) 2014 Elsevier Ltd.

  synthesis, and biological investigation of novel antimalarial agents with low potential to develop resistance and structurally based on a highly conjugated scaffold. Starting from a new hit, the designed modifications were performed hypothesizing a specific interaction with free heme and generation of radical intermediates. This approach provided antimalarials with improved potency against chloroquine-resistant

  疟疾是贫困地区的主要健康问题，在这些地区，人们迫切需要以负担得起的价格购买新的抗寄生虫药。我们在此报告了新型抗疟疾药物的设计，合成和生物学研究，这些药物具有发展抗药性的低潜力，并且在结构上基于高度偶联的支架。从新的命中开始，进行设计的修饰，假设与游离血红素发生特定的相互作用并产生自由基中间体。与已知药物相比，该方法为抗疟药提供了增强的抗氯喹抗疟原虫能力。确定了许多结构-活性关系（SAR）趋势，在合成的类似物中，吡咯烷基甲基亚芳基和咪唑衍生物5r，5t，发现8b和8b是新系列中最有效的抗疟药。研究了新化合物的作用机理，并评估了它们的体内活性。
