  Antagonists of human CCR5 receptor containing 4-(pyrazolyl)piperidine side chains. Part 1: Discovery and SAR study of 4-pyrazolylpiperidine side chains

  摘要：

  Replacement of the flexible connecting chains between the piperidine moiety and an aromatic group in previous CCR5 antagonists with heterocycles, such as pyrazole and isoxazole, provided potent CCR5 antagonists with excellent anti-HIV-1 activity in vitro. SAR studies revealed optimal placement of an unsubstituted nitrogen atom in the heterocycle to be meta to the bond connected to the 4-position of piperidine. Truncation of a benzyl group to a phenyl group afforded compounds with dramatically improved oral bioavailability, albeit with reduced activity. (C) 2004 Elsevier Ltd. All rights reserved.

  名称：

  4-N-linked-heterocyclic piperidine derivatives with high affinity and selectivity for human dopamine D4 receptors

  摘要：

  The syntheses of a number of different N-linked heterocyclic pyrazole replacements based on the structure 1 are described (compounds 3-12) as hD4 ligands. After further optimisation the best compound identified was 13 which has high affinity for hD4 (5.2 nM) and >300-fold selectivity for hD4 receptors over hD2 and hD3 receptors.
