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 chemicalsynthesis of the hydroxylated phase‐I‐metabolites 9, 11, and 12 is effected by Triton B catalysed saponification of the bromides 7 and 8 and boron tribromide mediated ether cleavage of 6 and 10 to 11 and 12. The chelated enol 9 was coupled with the bromosugar 13 to afford the glucuronide 14 that was saponified to the phase‐II‐metabolite 15.
