Geometrically Constrained Analogues of N-Benzylindolylglyoxylylamides: [1, 2, 4]Triazino[4, 3-a]benzimidazol-4(10H)-one Derivatives as Potential New Ligands at the Benzodiazepine Receptor

3‐ethoxycarbonyl [1, 2, 4]triazino [4, 3‐a]benzimidazol‐4(10H)‐one 14 and its N(10)‐methyl analogue 15 closely related to 3‐alkoxycarbonyl‐β‐carbolines I were also investigated. The title compounds exhibited a lower affinity compared with the corresponding indolylglyoxylylamide derivatives II. Attempts were made to rationalize these results taking into account the possible tautomeric equilibria involving
合成了一系列 3 - 苄氨基 - 和 3 - 芳基烷基氨基羰基 [1, 2, 4] 三嗪基 [4, 3 - a] 苯并咪唑 1-12 并进行生物学分析,作为 N - 苄基吲哚基乙氧基酰胺 II 的几何受限类似物,它们是高亲和力配体在苯二氮卓受体(BzR)。中间体3-乙氧基羰基[1,2,4]三嗪基[4,3-a]苯并咪唑-4(10H)-one 14及其与3-烷氧基羰基-β-咔啉密切相关的N(10)-甲基类似物15 . 也被调查了。与相应的吲哚基乙醛酰胺衍生物 II 相比,标题化合物表现出较低的亲和力。考虑到涉及这些配体的可能的互变异构平衡,试图使这些结果合理化。
