We describe structure-based optimization of a series of novel 2,4-diaminopyrimidine MK2 inhibitors. Co-crystal structures (see accompanying Letter) demonstrated a unique inhibitor binding mode. Resulting inhibitors had IC(50) values as low as 19nM and moderate selectivity against a kinase panel. Compounds 15, 31a, and 31b inhibit TNFalpha production in peripheral human monocytes.
