  C-9 and N-Substituted Analogs of cis-(3aR)-(-)-2,3,3a,4,5,9b-Hexahydro-3-propyl-1H-benz[e]indole-9-carboxamide: 5-HT1A Receptor Agonists with Various Degrees of Metabolic Stability

  摘要：

  Closely related analogs of the 5-HT1A receptor agonist cis-(3aR)-(-)-2,3,3a,4,5,9b-hexahydro-3-propyl-LH-benz[e]indole-9-carboxamide (1, U93385) were synthesized and pharmacologically evaluated. 9-Carboxamide analogs with varied nitrogen substitution (R(2)) were synthesized, and their serotonergic activity was evaluated in vitro and in vivo. Many of these compounds were incubated in the presence of rat hepatocytes, and the metabolic stability in vitro was compared to that of compound 1. Only the N-methyl and N-ethyl analogs ((-)-5a and (-)-5b) were more stable than compound 1, indicating that N-dealkylation is a major route of metabolism in this series. In addition, these analogs were found to be partial 5-HT1A receptor agonists in vivo. Modifications were also made to the carboxamide functionality of compound 1 (R(1) in 2) to yield substituted amides or ketones. Among these analogs, the methyl ketone (-)-15a was found to be a 5-HT1A agonist with full intrinsic activity in vivo and was approximately 20 times more potent than compound 1 and 5 times more potent than 8-OH-DPAT.

  顺式-（3aR）-（-）-2,3,3a，4,5,9b-六氢-3-丙基-1H-苯并[e]吲哚-9-羧酰胺的合成及生物活性：有力和选择性5 -HT1A受体激动剂，口服有效。

  摘要：

  顺式（3aR）-（-）-2,3,3a，4,5,9b-六氢-3-丙基-1H-苯并[e]吲哚-9-羧酰胺（（-）-在图3a）中描述了U93385。还合成并评估了顺式外消旋体及其对映体以及相应的反式对映体。这些类似物的合成是通过将9-羟基前体四步转化为9-羧酰胺或使用（R）-α-甲基苄基作为手性助剂的替代合成来实现的。发现顺式消旋体（+/-）-3a是选择性和有效的5-HT1A受体激动剂，其活性存在于顺式-（3aR）-对映体（-）-3a中。顺式（3aS）-对映体（+）-3a和反式-（3aR）-对映体（-）-3b显示部分5-HT1A激动剂活性，而其他反式-（3aS）-对映体（+）-3b没有显示活动。对映体（-）-3a在体外和体内生化/行为分析中均具有选择性。该化合物可有效降低小鼠的直肠温度，降低大鼠中脑血清素能神经元的放电速度，并抑制大鼠脑5-HT的合成。该化合物还减少了麻醉猫的交感神经放电和血压，
