英文摘要 | AIM: To study the characteristics of tetrahydroprotoberberines (THPB) on dopamine D-1 and D-2 receptors and elucidate their structure-activity relationship. METHODS: Radioligand assay in vitro with a two-site model program analysis. RESULTS: Four THPB with two hydroxyl groups on C-2 and C-9 or C-2 and C-10 exhibited R-H and R-L two binding sites to D-1 receptors and guanosine triphosphate regulated the R-H binding site of SPD and THPB-132A in competition assay, while eleven THPB including nonhydroxy-THPB, monohydroxy-THPB, and THPB with two hydroxyl groups attaching to C-3 and C-10 showed one binding site to D-1 receptors under the same conditions. However, the tested eleven THPB all manifested one binding site to D-2 receptors in competition assay, and the 2-hydroxy-THPB had the most potent affinity for D-2 receptors. CONCLUSION: Dihydroxy-THPB with two hydroxyl groups attaching to C-2 and C-9 or C-2 and C-10 possess the intrinsic activity of agonist to D-1 receptors, while the other THPB do not. The tested eleven THPB all are the antagonists of D-2 receptors. |
