Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/24356814

Ralimetinib (LY2228820), a trisubstituted imidazole derivative, is a potent and selective, ATP-competitive inhibitor of the α- and β-isoforms of p38 mitogen-activated protein kinase. LY2228820 produced significant tumor growth delay in multiple in vivo cancer models (melanoma, non-small cell lung cancer, ovarian, glioma, myeloma, breast). Eli Lilly is developing ralimetinib for the treatment of cancer.

Sample Use Guides

In Vivo Use Guide

The recommended phase II dose of Ralimetinib in patients with advanced cancer was 300 mg every 12 hours as monotherapy or in combination with tamoxifen.

Route of Administration: Oral

In Vitro Use Guide

In cell-based assays, Ralimetinib (LY2228820) potently and selectively inhibited phosphorylation of MK2 (Thr334) in anisomycin-stimulated HeLa cells (at 9.8 nmol/L by Western blot analysis) and anisomycin-induced mouse RAW264.7 macrophages (IC(50) = 35.3 nmol/L) with no changes in phosphorylation of p38α MAPK, JNK, ERK1/2, c-Jun, ATF2, or c-Myc ≤ 10 μmol/L. LY2228820 also reduced TNF-α secretion by lipopolysaccharide/IFN-γ-stimulated macrophages (IC(50) = 6.3 nmol/L).
