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.
