  N-Substituted (2,3-Dihydro-1,4-benzodioxin-2-yl)methylamine Derivatives as D₂ Antagonists/5-HT_1A Partial Agonists with Potential as Atypical Antipsychotic Agents

  摘要：

  A series of N-substituted 1-(2,3-dihydro-1,4-benzodioxin-2-yl)methylamine derivatives with D-2 antagonist/5-HT1A partial agonist activity has been prepared as potential atypical antipsychotic agents. Optimization of in vitro receptor binding activity and in vivo activity in rodent models of psychosis has led to compound 24, which showed good affinities for human D-2, D-3, and 5-HT1A receptors but significantly less affinity for human alpha(1) adrenoceptors and rat H-1 and muscarinic receptors. In rodents, 24 showed functional D-2-like antagonism and 5-HT1A partial agonism. After oral dosing, 24 showed good activity in rodent antipsychotic tests and very little potential to cause extrapyramidal side effects (EPS), as measured by its ability to induce catalepsy in rats only at very high doses. In the light of this promising profile of activity, 24 has been selected for clinical investigation as a novel antipsychotic agent with a predicted low propensity to cause EPS.

  allow the development of new types of structures based on 1,4-benzodioxine. Forty-one new 1,4-benzodioxine molecules substituted at different positions of the heterocyclic nucleus were synthesized to determine the minimum structural requirements by studying structure-activity relationships. Eighteen of them were tested in vitro and in vivo for their anti-inflammatory activity related to the antagonist

  新的白三烯 B4 (LTB4) 拮抗剂已被合成，可被视为潜在的抗炎药物。含有 1,4-苯并二恶英双氧化核的结构构成了一组潜在的白三烯 B4 (LTB4) 拮抗剂。本研究的目的是获得有效和选择性的 LTB4 拮抗剂，作为阐明 LTB4 在炎症过程中的作用的一种方式，从而允许开发基于 1,4-苯并二恶英的新型结构。合成了 41 个在杂环核不同位置取代的新 1,4-苯并二恶英分子，通过研究构效关系确定最低结构要求。其中十八个在体外和体内进行了测试因为它们的抗炎活性与 LTB4 的拮抗剂特性有关。药理学试验表明化合物24b、24c和24e具有令人满意的体外活性，IC50 分别为 288、439、477 nM。使用在体外试验24b中表现出更大活性的化合物进行的体内试验的结果显示出显着的抗炎特性。

  None of these derivatives are as potent or selective as 5, although some do display a degree of selectivity as antagonists. Some derivatives were found to possess agonist properties that, with the exception of 23, favored the postsynaptic site.
