  Part 2: Structure–activity relationship (SAR) investigations of fused pyrazoles as potent, selective and orally available inhibitors of p38α mitogen-activated protein kinase

  摘要：

  A novel class of pyrazolopyridazine p38 alpha mitogen-activated protein kinase (MAPK) inhibitors is disclosed. A structure activity relationship (SAR) investigation was conducted driven by the ability of these compounds to inhibit the p38a enzyme, the secretion of TNF alpha in a LPS-challenged THP1 cell line and TNF alpha-induced production of IL-8 in the presence of 50% human whole blood (hWB). This study resulted in the discovery of several inhibitors with IC50 values in the single-digit nanomolar range in hWB. Further investigation of the pharmacokinetic profiles of these lead compounds led to the identification of three potent and orally bioavailable p38 alpha inhibitors 2h, 2m, and 13h. Inhibitor 2m was found to be highly selective for p38 alpha/beta over a panel of 402 other kinases in Ambit screening, and was highly efficacious in vivo in the inhibition of TNF alpha production in LPS-stimulated Lewis rats with an ED50 of ca. 0.08 mg/kg.

  Part 1: Structure–Activity Relationship (SAR) investigations of fused pyrazoles as potent, selective and orally available inhibitors of p38α mitogen-activated protein kinase

  摘要：

  A novel class of fused pyrazole-derived inhibitors of p38 alpha mitogen-activated protein kinase (MAPK) is disclosed. These inhibitors were evaluated for their ability to inhibit the p38a enzyme, the secretion of TNF alpha in a LPS-challenged THP1 cell line and TNF alpha-induced production of IL-8 in 50% human whole blood. This series was optimized through a SAR investigation to provide inhibitors with IC50 values in the low single-digit nanomolar range in whole blood. Further investigation of their pharmacokinetic profiles led to the identification of two potent and orally bioavailable p38 inhibitors 10m and 10q. Inhibitor 10m was found to be efficacious in vivo in the inhibition of TNFa production in LPS-stimulated Lewis rats with an ED50 of 0.1 mg/kg while 10q was found to have an ED50 of 0.05-0.07 mg/kg.
