  Synthesis and Molecular Modeling of 1-Phenyl-1,2,3,4-tetrahydroisoquinolines and Related 5,6,8,9-Tetrahydro-13bH-dibenzo[a,h]quinolizines as D1 Dopamine Antagonists

  摘要：

  New 1-phenyl-1,2,3,4-tetrahydroisoquinolines and related 5,6,8,9-tetrahydro-13bH-dibenzo[a,h]-quinolizines were prepared as ring-contracted analogs of the prototypical 1-phenyl-2,3,4,5-tetrahydrobenzazepines (e.g., SCH23390) as a continuation of our studies to characterize the antagonist binding pharmacophore of the D-1 dopamine receptor. Receptor affinity was assessed by competition for [H-3]SCH23390 binding sites in rat striatal membranes. The 6-bromo-1-phenyltetrahydroisoquinoline analog 2 of SCH23390 1 had D-1 binding affinity similar to that for the previously reported 6-chloro analog 6, whereas the 6,7-dihydroxy analog 5 had significantly lower D-1 affinity. Conversely, neither 6-monohydroxy- (3) nor 7-monohydroxy-1-phenyltetrahydroisoquinolines (4) had significant affinity for the D-1 receptor. These results demonstrate that 6-halo and 7-hydroxy substituents influence D-1 binding affinity of the 1-phenyltetrahydroisoquinolines in a fashion similar to their effects on 1-phenyltetrahydrobenzazepines. azepines. The conformationally constrained 3-chloro-2-hydroxytetrahydrodibenzoquinolizine 9 had much lower affinity relative to the corresponding, and more flexible, 6-chloro-7-hydroxy-1-phenyltetrahydroisoquinoline 6. Similarly, 2,3-dihydroxytetrahydrodibenzoquinolizine 10 had much lower D-1 affinity compared to dihydrexidine 14, a structurally similar hexahydrobenzo[a]phenanthridine that is a high-affinity full D-1 agonist. Together, these data not only confirm the effects of the halo and hydroxy substitutents on the parent nucleus but demonstrate the pharmacophoric importance of both the nitrogen position and the orientation of the accessory phenyl ring in modulating D-1 receptor affinity and function. Molecular modeling studies and conformational analyses were conducted using the data from these new analogs in combination with the data from compounds previously synthesized. The resulting geometries were used to refine a working model of the D-1 antagonist pharmacophore using conventional quantitative structure-activity relationships and three-dimensional QSAR (CoMFA).

  用作抗惊厥药的 1,2,3,4-四氢异喹啉衍生物的 3D 药效团模型

  摘要：

  最近披露的一系列 6,7-二甲氧基-1,2,3,4-四氢异喹啉衍生物作为一类新的非竞争性 AMPA 受体拮抗剂，获得了预测抗惊厥活性的 3D 药效团模型。训练集包括 17 种化合物，它们对 DBA/2 小鼠的听觉癫痫发作具有不同的效力。使用 Catalyst 4.9 的 HypoGen 模块生成的最佳统计假设由五个特征组成：两个氢键受体、两个疏水特征和一个疏水芳族区域，提供了一个相关系数为 0.919 的模型。所获得的模型是设计一些含有四氢异喹啉支架的新型抗惊厥药的有效工具。此外，为了解释新设计的 N-取代衍生物的不同程度的功效，

  An enantioselective, copper-catalyzed alkynylation of cyclic α,α-diaryl ketiminium ions has been developed to deliver isoquinoline products with diaryl, tetrasubstituted stereocenters. The success of this reaction relied on identification of Ph-PyBox as the optimal ligand, i-Pr2NEt as the base, and CHCl3 as the solvent. A broad scope and functional group tolerance were observed. Notably, the use of
