  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.

  摘要：

  已经合成了几种N-酰基-3,5-二甲氧基-4-羟基苯基烷基胺，并评估了它们使邻苯二酚9-甲基转移酶（COMT）失活的能力。发现N-碘乙酰基-3,5-二甲氧基-4-羟基苯乙胺可快速且不可逆地使该酶失活。相应的N-溴乙酰基衍生物也使COMT失活，但速率比N-碘乙酰基衍生物慢。N-乙酰基和N-富芳基衍生物完全没有活性。这些试剂对COMT的灭活似乎是通过可解离的复合物中的单分子反应而不是非特异性双分子反应进行的。使用变化链长的N-碘乙酰基苯基烷基胺测定相对于结合这些抑制剂的芳族部分的位点被修饰的氨基酸残基的接近度。在这些抑制剂中，分隔芳香环和碘乙酰胺部分的亚甲基碳的数量不会极大地影响与COMT的结合，也不会影响酶的失活速度。从这些观察结果可以得出结论，被这类亲和标记试剂修饰的氨基酸部分必须相对接近或部分结合这些抑制剂的芳族区域。

  The number of methylene carbons separating the aromatic ring and the iodoacetamide moiety in these inhibitors did not greatly influence the binding to COMT nor did it affect how rapidly the enzyme was inactivated. From these observations it was concluded that the amino acid moiety being modified by this class of affinity labeling reagents must be relatively close to or part of the site which binds
