30.0mg/ml Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Ralimetinib (LY2228820) dimesylate is a novel and potent inhibitor of p38 MAPK with IC50 of 7 nM in a cell-free assay, does not alter p38 MAPK activation. Phase 1/2.
in vitro LY2228820 inhibits p38α, as well as the level of phosphoMAPKAPK-2 (pMK2) in RAW 264.7 cells, with IC50 values of 7 nM and 34.3 nM, respectively. Furthermore, LY2228820 inhibits lipopolysaccharide (LPS)-induced TNFα formation in murine peritoneal macrophages, with IC50 of 5.2 nM. [1] In multiple myeloma (MM) cells, including INA6, RPMI-8226, U266, and RPMI-Dox40, LY2228820 (200 nM–800 nM) significantly blocks p38MAPK signaling, as revealed by its inhibition on phosphorylation of HSP27, a downstream target of p38MAPK, without affecting the expression level of HSP27. LY2228820 (200 nM–400 nM) enhances bortezomib-induced cytotoxicity and apoptosis, but LY2228820 alone doesn't inhibit the growth of MM.1S cells. LY2228820 (200 nM–800 nM) also inhibits secretion of IL-6 and MIP-1α in long-term BM stromal cells (LT-BMSCs), BM mononuclear cells (BMMNCs), peripheral blood (PB) CD138+, CD138− or PB CD14+ cells. LY2228820 (400 nM–800 nM) also blocks osteoclastogenesis from CD14+ cells. [2]
in vivo In LPS-induced mice, LY2228820 effectively inhibits the formation of TNFα with a threshold minimum 50% effective dose (TMED50) less than 1 mg/kg. In a rat model of collagen-inducedarthritis (CIA), LY2228820 displays potent effects on paw swelling, bone erosion, and cartilage destruction, with a threshold minimum 50% effective dose (TMED50)of 1.5 mg/kg.

プロトコル(参考用のみ)

キナーゼアッセイ Inhibition of p38α
Inhibition of p38α is determined using recombinant human p38α in a standard filter binding protocol using ATP[γ-33P] and EGFR 21-mer peptide as substrate. Functional inhibition of TNFα in murine peritoneal macrophages is determined using LPS stimulation in the presence of LY2228820. To assess p38α activity in cells more directly, RAW 264.7 cells are treated with LY2228820 and then stimulated with anisomycin. The level of p38α activity is detected using a phosphoMAPKAPK-2 (pMK2) (Thr 334) antibody which reacts with a residue specifically phosphorylated by p38α.
細胞アッセイ 細胞株 MM cells, including INA6, RPMI-8226, U266, and RPMI-Dox40
濃度 200 nM–800 nM
反応時間 48 hours
実験の流れ MTT assays and APO 2.7 staining are performed to assess cellular proliferation and induction of apoptosis, respectively. Viability is expressed as percent viable cells. Apoptosis in cells is evaluated by APO 2.7 staining. For detection of mitochondrial membrane protein 7A6 expressed in apoptotic cells, cells are incubated with APO 2.7 reagent for 20 min. Expression of APO 2.7 is determined using an EPICS XL flow cytometer.
動物実験 動物モデル Lipopolysaccharide (LPS)-induced Balb/c mice
