• 產品描述： RWJ-67657 (JNJ 3026582) is an orally active and selective p38α and p38β MAPK inhibitor with IC50s of 1 and 11 μM, respectively. RWJ-67657 displays no activity at p38γ and p38δ, and exhibits cardio protective effect. Anti-inflammatory and anti-tumor activity

• 靶點： p38α:1 μM (IC50);p38β:11 μM (IC50);p38MAPK

• 體外研究：
  RWJ-67657 inhibits the release of TNF-α by lipopolysaccharide (LPS)-treated human peripheral blood mononuclear cells with an IC50 of 3 nM, as well as the release of TNF-α from peripheral blood mononuclear cells treated with the superantigen staphylococcal enterotoxin B, with an IC50 value of 13 nM. RWJ67657 (10 μM; 24 hours) decreases colony formation in MCF-7 cells. Cell Proliferation Assay Cell Line: MCF-7 breast carcinoma cells Concentration: 10 μM Incubation Time: 24 hours Result: Decreased colony formation.

• 體內研究：
  RWJ-67657 inhibits TNF-alpha production in lipopolysaccharide-injected mice (87% inhibition at 50 mg/kg) and in rats (91% inhibition at 25 mg/kg) after oral administration. RWJ-67657 (50 mg/kg; administered orally; once per day for 7 consecutive days) displays a potent anti-inflammatory effect. By both improving the functioning of endothelial progenitor cells (EPCs) and reducing inflammation, EPC transplantation plus RWJ-67657 administration synergistically promotes angiogenesis and neurogenesis after diabetic stroke. Animal Model: The db/db mice (male, 8 weeks old) with EPCs Dosage: 50 mg/kg Administration: Administered orally; once per day for 7 consecutive days Result: Increased angiogenesis and neurogenesis of diabetic mice after cotreatment with EPCs transplantation.
