    New, selective 3-aminopyrazole based MK2-inhibitors were discovered by scaffold hopping strategy. The new derivatives proved to inhibit intracellular phosphorylation of hsp27 as well as LPS-induced TNFalpha release in cells. In addition, selected derivative 14e also inhibited LPS-induced TNFalpha release in vivo.
