LY2228820 is a novel and potent p38MAPK inhibitor with potent antiinflammatory activity. LY2228820 significantly inhibited phosphorylation of MAPKAPK2 and/or HSP27, down stream targets of p38MAPK, in both multiple myeloma (MM) cell lines and LT-BMSCs. LY2228820 is a potential candidate to improve MM patient outcome both by enhancing the effect of Bortezomib (B675700) and by reducing osteoskeletal events.
