Org 48762-0
Based on 1 Customer Validation
Org 48762-0 (UR13870) is a potent, orally active and selective p38 inhibitor with an EC50 of 0.1 μM for p38α kinase. Org 48762-0 shows a high degree of kinase selectivity for p38α and p38β over other kinases. Org 48762-0 reduces Lipopolysaccharides (HY-D1056) (LPS)-induced TNFα release. Org 48762-0 can be used for the study of rheumatoid arthritis (RA) and Werner syndrome.

Biological Activity
|
p38α 0.1 nM (EC50) |
Org 48762-0 completely inhibits LPS-induced TNFα release from peripheral blood mononuclear cells (PBMC) with an EC50 value of 0.06 μM. Org 48762-0 dose-dependently inhibits stress-induced MK2 translocation, with an EC50 value of 0.69 μM[1].
Org 48762-0 (0.1-10 μM; pre-incubated for 30 min) is capable of inhibiting IL-1β-induced signalling cascades, consequently interfering with production of proinflammatory cytokines[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:THP-1 cells stimulated with IL-1β.
-
Concentration:0.1 μM, 1 μM, 10 μM
-
Incubation Time:Pre-incubated for 30 min and subsequently stimulated with 10 ng/mL IL-1β.
-
Result:Inhibited IL-1β-induced phosphorylation of p38 kinase as well as of HSP27, a downstream marker of p38 kinase activity.
In mice, Org 48762-0 shows an oral bioavailability of 85% and exhibits sustained systemic exposure (>1 μM) for 24 h after a dose of 4.0 mg/kg. When Org 48762-0 is administered intravenously (1.6 mg/kg), the compound shows a low volume of distribution in steady state (Vss: 50.0 mL/kg) and a low clearance (CL: 9.0 mL/h/kg), resulting in a mean residence time of 5.3 h[1].

-
Animal Model:Female Balb/c mice (7- to 8-week old) were intraperitoneally challenged with LPS (20 μg/mouse) dissolved in PBS to induce inflammatory responses[1].
-
Dosage:0.3 mg/kg, 1 mg/kg, 3 mg/kg
-
Administration:p.o; once
-
Result:Dose-dependently inhibited LPS-induced TNFα production.
Significantly reduced serum levels of IL-1β, IL-6, macrophage inflammatory protein-1α/β, RANTES and MCP-1 induced by LPS challenge.
