ABSTRACT:
Compounds are provided that act as potent antagonists of the CCR1 receptor, and have in vivo anti-inflammatory activity. The compounds are 3-imidazoyl-pyrazolo[3,4-b]pyridine derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR1-mediated disease, and as controls in assays for the identification of competitive CCR1 antagonists.
