阿尔茨海默病研究 - 阿尔茨海默病的根本原因是氧化和硝化作用 现有治疗方法大多仅针对间接因素如错误折叠的淀粉样蛋白和tau蛋白或神经炎症 而非直接清除导致氧化和硝化的化合物如过氧化氢和过氧亚硝酸盐 因此多数疗法仅能短暂延缓早期病情进展 [1] - 某些天然产物如人参精油通过芳香疗法可抑制氧化和硝化作用 清除氧化应激和亚硝化应激的介质 并部分修复损伤 此类治疗有望实现病情稳定 [1] - 研究重点关注Anavex和Cyclo Therapeutics等公司 因其候选药物可能具备上述作用机制 [1] 药物机制分析 - Anavex的blarcamesine在长期开放标签试验中表现与Aricept相当 未显示出更优疗效 [1] - 当前阿尔茨海默病药物研发存在局限性 主要聚焦于间接病理因素 缺乏针对氧化/硝化损伤的直接修复能力 [1]
