R-130823
R-130823 is an orally active, highly selective p38α inhibitor with an IC50 of 22 nM against p38α, an IC50 of 820 nM against p38β, and no activity against p38γ or p38δ. R-130823 downregulates downstream cartilage degradation and inflammatory mediators, and inhibits the release of MMP-13, MMP-1 and PGE2. R-130823 reduces hind paw swelling, improves hyperalgesia, and blocks arthritis progression. R-130823 is applicable to research related to osteoarthritis and rheumatoid arthritis.

R-130823 potently inhibits purified p38α kinase (IC50 = 22 nM), moderately inhibits purified p38β kinase (IC50 = 820 nM), and shows no activity against p38γ or p38δ[1].
R-130823 (4-2500 nM; 1 h) inhibits the release of MMP-13 (IC50 = 20 nM), MMP-1 (IC50 = 230 nM) and PGE2 (IC50 = 3.9 nM) induced by IL-1β in human primary chondrocytes[1].
R-130823 (0.1-10 μM; incubated for 3 weeks with weekly compound supplementation) inhibits IL-1α/oncostatin M-induced collagen cleavage in bovine nasal cartilage explants, with an IC50 of 510 nM[1].

R-130823 (1-30 mg/kg; p.o.; single dose) dose-dependently ameliorates adjuvant-induced hyperalgesia in rats, with sustained analgesic activity lasting up to 24 hours at the highest tested dose of 30 mg/kg[2].
R-130823 (3-30 mg/kg/day; p.o.; once daily; 14 days) dose-dependently blocks arthritis progression in murine collagen-induced arthritis, with statistically significant suppression of arthritis index (P < 0.0001) and reduced joint tissue inflammation at the highest tested dose of 30 mg/kg/day[2].
