  新型芳基酰胺作为脑渗透接头蛋白 2 相关激酶 1 (AAK1) 抑制剂治疗神经性疼痛的发现、结构-活性关系和体内评价

  摘要：

  有效治疗慢性疼痛，特别是神经性疼痛，没有通常伴随当前可用治疗选择的副作用，是一个显着未满足的医疗需求领域。小鼠基因敲除的表型筛选导致发现接头蛋白 2 相关激酶 1 (AAK1) 是神经性疼痛的潜在治疗靶点。一系列基于芳基酰胺的 AAK1 抑制剂的构效关系的合成和优化导致59的鉴定，这是一种脑渗透性 AAK1 选择性抑制剂，被证明是一种有价值的工具化合物。在小鼠中评估了化合物59对 μ2 磷酸化的抑制。对59 人进行的研究在疼痛模型中证明该化合物在持续性疼痛的 II 期福尔马林模型和大鼠神经性疼痛的慢性收缩损伤诱导模型中是有效的。这些结果表明 AAK1 抑制是治疗神经性疼痛的一种有前途的方法。

  discernible correlation with their antimicrobial activity. This trend was particularly pronounced for colistin-resistant pathogens. The most active compounds demonstrated competitive activity against a panel of Gram-negative pathogens, while exhibiting low in vitro cytotoxicity. Importantly, most of these hits also retained (or even had increased) potency against colistin-susceptible strains. These findings

  鉴于人类病原体中抗菌素耐药性的普遍性增加，迫切需要针对多重耐药 （MDR） 细菌的抗生素。特别是，对用于治疗严重革兰阴性 MDR 感染的最后手段抗生素粘菌素迅速出现的耐药性至关重要。在这里，探索了一系列含有非天然氨基酸的多粘菌素，一些类似物对大肠杆菌、肺炎克雷伯菌、鲍曼不动杆菌和铜绿假单胞菌表现出优异的抗菌活性。该系列化合物的疏水性（通过在反相分析 HPLC 中的保留性测量）与其抗菌活性表现出明显的相关性。这种趋势对于粘菌素耐药病原体尤为明显。最活跃的化合物对一组革兰氏阴性病原体表现出竞争活性，同时表现出低体外细胞毒性。重要的是，这些命中中的大多数还保留（甚至增加了）对粘菌素敏感菌株的效力。这些发现推断，微调疏水性可能使设计出具有良好活性特征的多粘菌素类似物。
