  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.
