  Design, synthesis, and pharmacological evaluation of novel tetrahydroprotoberberine derivatives: Selective inhibitors of dopamine D1 receptor

  摘要：

  A series of new tetrahydroprotoberberine (THPB) derivatives were designed, synthesized, and tested for their binding affinity towards dopamine (D-1 and D-2) and serotonin (5-HT1A and 5-HT2A) receptors. Many of the THPB compounds exhibited high binding affinity and activity at the dopamine D-1 receptor, as well as high selectivity for the D-1 receptor over the D-2, 5-HT1A, and 5-HT2A receptors. Among these, compound 19c exhibited a promising D-1 receptor binding affinity (K-i = 2.53 nM) and remarkable selectivity versus D2R (inhibition = 81.87%), 5-HT1AR (inhibition = 61.70%), and 5-HT2AR (inhibition = 24.96%). Compared with l-(S)-stepholidine (l-SPD) (D-1 K-i = 6.23 nM, D-2 K-i = 56.17 nM), compound 19c showed better binding affinity for the D-1 receptor (2.5-fold higher) and excellent D-2/D-1 selectivity. Functional assays found compounds 18j, 18k, and 19c are pure D-1 receptor antagonists. These results indicate that removing the C10 hydroxy group and introducing a methoxy group at C11 of the pharmacophore of l-SPD can reverse the function of THPB compounds at the D-1 receptor. These results are in accord with molecular docking studies. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.

  1-Bn-DHIQs to 1-Bz-DHIQs without concomitant excessive oxidation of 1-Bz-DHIQs to 1-Bz-IQs is very important for the syntheses of 1-Bz-DHIQ alkaloids and analogues. In this article, we developed a novel Cu(ii)-catalyzed and acid-promoted highly regioselective oxidation of tautomerizable C(sp3)-H bonds adjacent to the C-1 positions of various 1-Bn-DHIQs. It was observed that when 0.2 equiv. of Cu(OAc)2·2H2O

  一种温和、高效、环保的方法将 1-Bn-DHIQs 氧化为 1-Bz-DHIQs，且不会同时将 1-Bz-DHIQs 过度氧化为 1-Bz-IQs，这对于 1-Bz 的合成非常重要。 -DHIQ 生物碱和类似物。在本文中，我们开发了一种新型 Cu(ii) 催化和酸促进的高度区域选择性氧化，可对各种 1-Bn-DHIQ 的 C-1 位置附近的可互变 C(sp3)-H 键进行氧化。据观察，当 0.2 当量时。 Cu(OAc)2·2H2O用作催化剂，3.0当量。以AcOH为添加剂，空气（O2）为清洁氧化剂，在25℃的DMSO中，各种1-Bn-DHIQ可以有效氧化为相应的1-Bz-DHIQ。特别是，在上述反应过程中几乎没有观察到1-Bz-DHIQs过度氧化为1-Bz-IQs。此外，该方法还成功应用于生物碱canelillinoxine的首次全合成。
