  Probing the Steric Space at the Floor of the D₁ Dopamine Receptor Orthosteric Binding Domain: 7α-, 7β-, 8α-, and 8β-Methyl Substituted Dihydrexidine Analogues

  摘要：

  To probe the space at the floor of the orthosteric ligand binding site in the dopamine D-1 receptor, four methylated analogues of dihydrexidine (DHX) were synthesized with substitutions at the 7 and 8 positions. The 8 alpha-axial, 8 beta-equatorial, and 7 alpha-equatorial were synthesized by photochemical cyclization of appropriately substituted N-benzoyl enamines, and the 7 beta-axial analogue was prepared by an intramolecular Henry reaction. All of the methylated analogues displayed losses in affinity when compared to DHX (20 nM): 8 beta-Me-ax-DHX (270 nM), 8 alpha-Me-eq-DHX (920 nM), 7 beta-Me-eq-DHX (6540 nM), and 7 alpha-Me-ax-DFLX (>10000 nM). Molecular modeling studies suggest that although the disruption of an aromatic interaction between Phe203(54.7) and Phe288(6.51) is the cause for the 14-fold loss in affinity associated with 8 beta-axial substitution, unfavorable steric interactions with Ser107(3.36) result in the more dramatic decreases in binding affinity suffered by the rest of the analogues.
