Abstract
A novel structural class of p38 mitogen-activated protein (MAP) kinase inhibitors consisting of substituted 4-(phenylamino)-pyrrolo[2,1- f][1,2,4]triazines has been discovered. An initial subdeck screen revealed that the oxindole-pyrrolo[2,1- f][1,2,4]triazine lead 2a displayed potent enzyme inhibition (IC 50 60 nM) and was active in a cell-based TNFalpha biosynthesis inhibition assay (IC 50 210 nM). Replacement of the C4 oxindole with 2-methyl-5- N-methoxybenzamide aniline 9 gave a compound with superior p38 kinase inhibition (IC 50 10 nM) and moderately improved functional inhibition in THP-1 cells. Further replacement of the C6 ester of the pyrrolo[2,1- f][1,2,4]triazine with amides afforded compounds with increased potency, excellent oral bioavailability, and robust efficacy in a murine model of acute inflammation (murine LPS-TNFalpha). In rodent disease models of chronic inflammation, multiple compounds demonstrated significant inhibition of disease progression leading to the advancement of 2 compounds 11b and 11j into further preclinical and toxicological studies.
