Pyrazolone methylamino piperidine derivatives as novel CCR3 antagonists
摘要:
The discovery and optimization of a novel class of potent CCR3 antagonists is described. Details of synthesis and SAR are given together with some ADME properties of selected compounds. An optimal balance between activities, physicochemical properties, and in vitro metabolic stability was reached by the proper choice of substituents. (c) 2007 Elsevier Ltd. All rights reserved.

The present invention provides a method for assaying alpha-methylacyl-CoA racemase activity. In the assay, a sample containing an alpha-methylacyl-CoA racemase or suspected of containing an alpha-methylacyl-CoA racemase is contacted with (2R)-pristanoyl-CoA. If alpha-methylacyl-CoA racemase is present in the sample, (2R)-pristanoyl-CoA is converted into (2S)-pristanoyl-CoA. The method then utilizes a cycling reaction system between (2S)-pristanoyl-CoA and trans-2,3-dehydropristanoyl-CoA to generate a detectable signal that corresponds to the alpha-methylacyl-CoA racemase activity. Kits for assaying alpha-methylacyl-CoA racemase based on the same principle are also provided.
