Pyrazolo-pyrimidines: A novel heterocyclic scaffold for potent and selective p38α inhibitors
摘要:
The synthesis and structure-activity relationships ( SAR) of p38 alpha MAP kinase inhibitors based on a pyrazolo-pyrimidine scaffold are described. These studies led to the identification of compound 2x as a potent and selective inhibitor of p38 alpha MAP kinase with excellent cellular potency toward the inhibition of TNF alpha production. Compound 2x was highly efficacious in vivo in inhibiting TNF alpha production in an acute murine model of TNF alpha production. X-ray co-crystallography of a pyrazolo-pyrimidine analog 2b bound to unphosphorylated p38 alpha is also disclosed. (C) 2008 Elsevier Ltd. All rights reserved.
