In the present report, the D3 receptor pharmacophore is modified in the 2,3-diCl- and 2-OCH3-phenylpiperazine class of compounds with the goal to improve D3 receptor affinity and selectivity. This extension of structure-activity relationships (SAR) has resulted in the identification of the first enantioselective D3 antagonists (R- and S-22) to be reported, wherein enantioselectivity is more pronounced at D3 than at D2, and that a binding region on the second extracellular loop (E2) may play a role in both enantioselectivity and D3 receptor selectivity. Moreover, we have discovered some of the most D3-selective compounds reported to date that show high affinity (Ki = 1 nM) for D3 and ∼400-fold selectivity over the D2 receptor subtype. Several of these analogs showed exquisite selectivity for D3 receptors over >60 other receptors, further underscoring their value as in vivo research tools. These lead compounds also have appropriate phys. characteristics for in vivo exploration and therefore will be useful in determining how intrinsic activity at D3 receptors tested in vitro is related to behaviors in animal models of addiction and other neuropsychiatric disorders. In the experiment, the researchers used many compounds, for example, 5-Fluoro-1-benzothiophene-2-carboxylic acid (cas: 70060-13-8Application of 70060-13-8).
5-Fluoro-1-benzothiophene-2-carboxylic acid (cas: 70060-13-8) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Application of 70060-13-8
