Tpl2 Kinase Inhibitor

A cell-permeable naphthyridine compound that acts as a potent, reversible, and ATP-competitive inhibitor of Tpl2 kinase (IC₅₀ = 50 nM). Displays significant selectivity over other related kinases (IC₅₀ = 5, >40, 110, 180, >400 and >400 µM for EGFR, MEK, MK2, p38, Src, and PKC, respectively). Shown to inhibit LPS-induced TNF-α production both from primary human monocytes and in whole blood (IC₅₀ = 700 nM and 8.5 µM, respectively).

Cell permeable: yes
