  名称：

  1-(3-Cyanobenzylpiperidin-4-yl)-5-methyl-4-phenyl-1,3-dihydroimidazol-2-one:  A Selective High-Affinity Antagonist for the Human Dopamine D₄ Receptor with Excellent Selectivity over Ion Channels

  摘要：

  After the requirement of pseudocycle formation in the ureas 3 and 7 for hD(4) binding and selectivity was confirmed, structural hybridization with the known hD(4) ligand 2 led to the design and identification of the lead 4-(2-oxo-1,3-dihydroimidazol-2-yl)piperidine . Optimization studies were carried out on 8 with the aim of achieving 1000-fold selectivity for hD(4) over all other receptors while retaining the good pharmacokinetic properties of the lead. After initial preparation of 8 as a minor component in a low-yielding reaction, a novel and regioselective "four-step/one-pot'' procedure was developed which proved to be applicable to rapid investigation of the SAR of the 1,3-dihydroimidazol-2-one ring. Various changes to substituents attached to the 3-, 4-, or B-position of the 1,3-dihydroimidazol-2-one core of 8 did not significantly improve selectivity for hD(4) over hD(2) and hD(3). Greater Selectivity( > 1000-foId) was ultimately achieved by meta substitution of the benzyl group of 8 with various substituents. Compounds 28, 31, and 32 all possess the required selectivity for hD(4) over the other dopamine subtypes, but only 32 has > 1000-fold selectivity over-all the key counterscreens we tested against. Compound 32 is an antagonist at hD(4) and has a good pharmacokinetic profile in the rat, with excellent estimated in vivo receptor occupancy, thus making it a potentially useful pharmacological tool to investigate the role of the D-4 receptor.
