General description

A non-ATP-competitive, reversible, selective inhibitor of p38α-mediated MK2a (mitogen-activated protein kinase-activated protein kinase 2a) phosphorylation (Kiapp = 330 nM). Does not inhibit p38α-mediated phosphorylation of the the other two known p38 substrates, MBP and ATF-2.
A reversible p-amidophenolic compound that selectively inhibits the phosphorylation of MK2a (mitogen-activated protein kinase-activated protein kinase 2a; Kiapp = 330 nM) by p38α in a non-ATP-competitive manner. Does not block the kinase activity of p38α towards the other two known p38 substrates, MBP and ATF-2.
