Usage

Uses

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.

Biological Activity

ly2228820 is a potent, selective, atp-competitive small-molecule inhibitor inhibiting α- and β-isoforms of p38 mapk with ic(50) values of 5.3nm and 3.2 nm, respectively1.in multiple myeloma (mm) cell lines, ly2228820 enhanced the cytotoxicity of bortezomiba via reducing bortezomib-induced phosphorylation of heat shock protein 27 (hsp27). ly2228820 significantly reduced il-6 secretion from bm mononuclear cells (bmmncs) and long term cultured-bm stromal cells (lt-bmscs). besides, ly2228820 can also inhibit secretion of macrophage inflammatory protein-1a (mip-1a) in bmmncs, cd138+ patient mm cells and normal cd14+ osteoclast cells 2.studies in mice implanted with b16-f10 melanoma showed that orally administered ly2228820 can effectively suppress the tumor-phospho-mk2 expression. treatment of ly2228820 caused a significant tumor growth delay in a549 nsclc xenograft models1.
