The compounds of formula (I), or its pharmaceutically acceptable salts, or any stereoisomer or mixture thereof, wherein: R1 and R1' are both H, or R1 and R1' are taken together forming a biradical of formula -CH2-C(R4)=CH-; R2 and R3 are radical independently selected from the group consisting of H, F, CI and (C1-C4)-alkyl; R4 is a (C1-C2)-alkyl radical; and n is an integer from 2 to 15, are useful for the treatment of a neurodegenerative disorder such as Alzheimer's disease.

amino group of huprine or the simplified 4-aminoquinoline analogue tacrine. Here, we describe the evaluation of a small in-house library and a second generation of newly synthesized derivatives, which has led to the identification of 13 side chain modified 4-aminoquinoline derivatives with submicromolar potencies against T. brucei. Among these compounds, the guanidinononyltacrine analogue 15e exhibits
目前针对人类非洲锥虫病 (HAT) 的药物存在几个严重的缺陷。因此,迫切需要寻找新的、有效的、脑渗透性的、安全的和廉价的抗锥虫化合物。我们最近报道了我们小组开发的作为抗胆碱酯酶剂的 4-氨基喹啉衍生物石杉碱 Y,对布氏锥虫表现出亚微摩尔效力并且其同源和异源二聚化可导致效力和选择性增加多达三倍。作为更有效的小分子抗 HAT 剂的替代策略,我们探索了在石杉碱的伯氨基基团或简化的 4-氨基喹啉类似物他克林上引入 ω-氰基烷基、ω-氨基烷基或 ω-胍基烷基链。在这里,我们描述了对一个小型内部库和第二代新合成衍生物的评估,这导致鉴定了 13 种侧链修饰的 4-氨基喹啉衍生物,这些衍生物对布氏锥虫具有亚微摩尔效力。在这些化合物中,胍壬吖啶类似物15e与母体石斛 Y 相比,抗锥虫效力提高 5 倍,选择性提高 10 倍,抗胆碱酯酶活性降低 100 倍。它是一种有趣的抗 HAT 铅,可以进一步优化以消除其剩余的抗胆碱酯酶活性。
