  Discovery of Novel 2-((Pyridin-3-yloxy)methyl)piperazines as α7 Nicotinic Acetylcholine Receptor Modulators for the Treatment of Inflammatory Disorders

  摘要：

  Herein we report the design, synthesis, and structure activity relationships for a new class of alpha 7 nicotinic acetylcholine receptor (nAChR) modulators based on the 2-((pyridin-3-yloxy)methyl)piperazine scaffold. The oxazolo[4,5-b]pyridine, (R)-18, and 4-methoxyphenylurea, (R)-47, were identified as potent and selective modulators of the alpha 7 nAChR with favorable in vitro safety profiles and good oral bioavailability in mouse. Both compounds were shown to significantly inhibit cellular infiltration in a murine model of allergic lung inflammation. Despite the structural and in vivo functional similarities in the compounds, only (R)-18 was shown to be an agonist. Compound (R)-47 demonstrated silent agonist activity. These data support the hypothesis that the anti-inflammatory activity of the alpha 7 nAChR is mediated by a signal transduction pathway that is independent of ion current.
