modelling studies it was also demonstrated that 6c, 6d and 8a mimicked very well the reference structures of 4a and its rigid analog 5. Another, more complex 1,2,3,4‐tetrahydroisoquinoline derivative 3, which served as a model compound to confirm the previously reported 5‐HT1A binding mode of derivatives 1a–d and 2, had the highest 5‐HT1A affinity (Ki = 6.7 ± 0.5 nM) of all the investigated compounds
一组 1-芳基哌嗪 (4) 1,2,3,4-四氢异喹啉 (6) 和 - 喹啉 (7) 的 5-HT1A 受体亲和力和电离常数,含有 N-(ω-芳烷基) 或 N-( E) 确定了肉桂基取代基以及两种吗啉衍生物 (8a, 8b)。结果表明,一些四氢异喹啉 (6c, 6d) 和吗啉 (8a) 衍生物是 5-HT1A 配体等电位的 1-苯基哌嗪 (4a) 和 1,2,3,4,4a5-六氢吡嗪并 [1,2-a] 吲哚 ( 5)。在分子模型研究的基础上,还证明 6c、6d 和 8a 很好地模拟了 4a 及其刚性类似物 5 的参考结构。 另一种更复杂的 1,2,3,4-四氢异喹啉衍生物 3,用作用于确认先前报道的衍生物 1a-d 和 2 的 5-HT1A 结合模式的模型化合物具有最高的 5-HT1A 亲和力(Ki = 6.7 ± 0.
