|
Preparation method |
The solubility of this compound in DMSO is > 30.7 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
9.8 nM-10 µM, 1 h |
|
Applications |
LY2228820 is a potent and selective inhibitor of the α- and β-isoforms of p38 MAPK with IC50 values of 5.3 and 3.2 nmol/L, respectively. In anisomycin-stimulated HeLa cells, LY2228820 efficiently inhibited phosphorylation of p38α MAPK substrate, MK2 (Thr334). LY2228820 also decreased TNF-α secretion induced by LPS/IFN-γ in mouse peritoneal macrophages. |
| Animal experiment [2]: | |
|
Animal models |
Athymic nude female mice |
|
Dosage form |
Oral administration, 20 and 40 mg/kg，three times daily |
|
Application |
LY2228820 reduced hemoglobin content in athymic nude mice. LY2228820 treatment resulted in a significant reduction of VEGF-A-stimulated vascularization in an ear angiogenesis model, indicating LY2228820 treatment impaired neoangiogenesis. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

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.
