A series of novel benzamide-derived compounds was designed, synthesized and pharmacologically evaluated. Among all 37 synthesized compounds, two series were developed with the modulation of the nature, the position of atoms or groups on the benzamide scaffold, but also the nature of the amine group separated from the benzamide with 2, 3 or 4 methylene groups.

设计,合成和药理学评估了一系列新颖的苯甲酰胺衍生的化合物。在所有37种合成化合物中,开发了两个系列,调节了苯甲酰胺骨架上原子或基团的性质,位置,以及从具有2、3或4个亚甲基的苯甲酰胺中分离出来的胺基的性质。针对sigma蛋白(sigma-1 S1R和sigma-2 S2R)的体外竞争结合试验表明,它们中的大多数赋予S2R / S1R选择性,而对SY5Y细胞无细胞毒性作用,特别是在第一个化合物7a-z的情况下。还评估了一些选定的化合物在40种受体上的激动剂和拮抗剂活性。结果表明,在苯甲酰胺支架上,其性质和与卤代原子的位置,长度链以及疏水部分对胺基的贡献至关重要。其中,在苯甲酰胺支架的4位带有Cl,CN或NO 2基团的化合物7i,w,y对S1R表现出优异的亲和力(Ki = 1.2–3.6 nM),对S2R的选择性(Ki高达1400 nM)和高选择性指数(IC 50(SY5Y) / Ki (S1R)
