BioAssay: AID 643562

Inhibition of P38alpha in human whole blood assessed as inhibition of TNF-alpha-induced IL-8 production incubated for 1 hr prior to TNFalpha challenge measured after 16 to 18 hrs by ECL based antibody sandwich assay

Structure-activity relationship (SAR) investigations of a novel class of triazolopyridazinone p38alpha mitogen activated protein kinase (MAPK) inhibitors are disclosed. From these studies, increased in vitro potency was observed for 2,6-disubstituted phenyl moieties and N-ethyl triazolopyridazinone cores due to key contacts with Leu108, Ala157 and Val38. Further investigation led to the more ..

Title: Identification of triazolopyridazinones as potent p38alpha inhibitors.

Abstract: Structure-activity relationship (SAR) investigations of a novel class of triazolopyridazinone p38alpha mitogen activated protein kinase (MAPK) inhibitors are disclosed. From these studies, increased in vitro potency was observed for 2,6-disubstituted phenyl moieties and N-ethyl triazolopyridazinone cores due to key contacts with Leu108, Ala157 and Val38. Further investigation led to the identification of three compounds, 3g, 3j and 3m that are highly potent inhibitors of LPS-induced MAPKAP kinase 2 (MK2) phosphorylation in 50% human whole blood (hWB), and possess desirable in vivo pharmacokinetic and kinase selectivity profiles.
