  Discovery and Optimization of Novel 3-Piperazinylcoumarin Antagonist of Chemokine-like Factor 1 with Oral Antiasthma Activity in Mice

  摘要：

  Chemokine-like factor 1 (CKLF1) is a novel functional cytokine that acts through receptor CC chemokine receptor 4 (CCR4). Activation of CCR4 by CKLF1 plays an important role in diseases such as asthma and multiple Sclerosis. This article describes a cell-based screening assay Using an FITC-labeled CCR4 agonist (CKLF1-C27), a CKLF1 peptide fragment. Screening of our in-stock small-molecule library identified a 3-piperazinylcoumarin analogue 1 (IC50 = 4.36 x 10(-6) M) that led to the discovery of orally active compound 41 (IC50 = 2.12 x 10(-8) M) through systematic optimization. Compound 41 blocked the calcium mobilization and chemotaxis induced by CKLF1-C27 and reduced the asthmatic pathologic changes in lung tissue of human CKLF1-transfected mice. Further studies indicated that compound 41 ameliorated pathological changes via inhibition of the NF-kappa B signal pathway.
