  名称：

  1-Methyl and 1-(2-hydroxyalkyl)-5-(3-alkyl/cycloalkyl/phenyl/naphthylureido)-1H-pyrazole-4-carboxylic acid ethyl esters as potent human neutrophil chemotaxis inhibitors

  摘要：

  In this paper we report the synthesis and the chemotaxis inhibitory activity of a number of 1H-pyrazole-4-carboxylic acid ethyl esters 2 functionalized in N1 with a methyl group or different hydroxyalkyl chains and in position 5 with a series of 3-substituted urea groups. These compounds were designed as development of previous pyrazole-urea derivatives that resulted potent IL8-induced neutrophil chemotaxis inhibitors in vitro. Most of the new compounds revealed a potent inhibition of both IL8- and fMLP-OMe-stimulated neutrophil chemotaxis. The most active compounds in the fMLP-OMe induced chemotaxis test showed IC(50) in the range 0.19 nM-2 mu M; but we observed a very strong inhibition in the IL8- induced chemotaxis test, having the most active compounds IC(50) at pM concentrations. In vivo compounds 2e and 2f, although to a lesser extent, at 50 mg/kg os decreased granulocyte infiltration in zymosan-induced peritonitis in mice. (C) 2009 Elsevier Ltd. All rights reserved.
