The invention relates to new piperidine derivatives of the formula (I) to their use as medicaments, to methods for their therapeutic use and to pharmaceutical compositions containing them.
The design synthesis, and biological evaluation of a series of pyrazolopyridines was carried out. Structural optimization of the aniline moiety of 4-anilinopyrazolopyridinc derivative 3a, which is one of the newly discovered chemical leads for PDE4 inhibitors from our in-house library, was performed successfully. The details of the discovery of new orally active PDE4 inhibitors, which are expected to show therapeutic potential, are presented and their structure-activity relationships are discussed. Pharmacological evaluation and pharmacokinetic data for representative compounds are also presented. (C) 2004 Elsevier Ltd. All rights reserved.
