"Pretreatment of hela cells with sb 203580, a pyridinyl imidazole compound that specifically inhibits p38 mitogen-activated protein kinase (mapk). It has previously been established that sb 203580 acts primarily to block the catalytic activity of p38 mapk. However, it has been suggested that in cells, the compounds could also inhibit p38 mapk activation by virtue of their ability to bind to the inactive enzyme."

"SB203580 is a competitive inhibitor of p38alpha and p38beta by blocking ATP binding to the kinase, while BIRB796 is an allosteric inhibitor of p38alpha, p38beta, and p38gamma."
