4.05mg/ml Taking the 1 mL working solution as an example, add 50 μL of 81 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. 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 Pamapimod (R-1503, Ro4402257) is a novel, selective inhibitor of p38 mitogen-activated protein kinase. It inhibits p38α and p38β enzymatic activity with IC50 values of 0.014±0.002 and 0.48± 0.04 microM, respectively with no activity against p38delta or p38gamma isoforms.
in vitro Pamapimod inhibited p38, but inhibition of JNK was not detected. Pamapimod also inhibited lipopolysaccharide (LPS)-stimulated tumor necrosis factor (TNF) α production by monocytes, interleukin (IL)-1β production in human whole blood, and spontaneous TNFα production by synovial explants from RA patients[1].
in vivo In murine collagen-induced arthritis, pamapimod reduced clinical signs of inflammation and bone loss at 50 mg/kg or greater. In a rat model of hyperalgesia, pamapimod increased tolerance to pressure in a dose-dependent manner, suggesting an important role of p38 in pain associated with inflammation. Pamapimod suppresses spontaneous production of TNFα by synovial explants from RA patients. LPS- and TNFα-stimulated production of TNFα and IL-6 in rodents also was inhibited by pamapimod[1].

実験の流れ

THP-1 cells, growing in log phase, were collected by centrifugation and resuspended in RPMI 1640 containing 5.5×10-5 M 2-mercaptoethanol and 10% fetal bovine serum to a final cell concentration of 2.5×106 cells/ml. Dilutions of pamapimod were predispensed in 25 μl aliquots (before addition of cells) into round-bottom 96-well plates. The starting concentration was 100 μM in 5% dimethyl sulfoxide, and six half-log serial dilutions were made. After the addition of 200 μl of cell suspension and 25 μl of 5 μg/ml LPS in medium, the final dimethyl sulfoxide concentration was 0.5%. Compounds were diluted an additional 10-fold, and the final LPS concentration was 500 ng/ml. The cell suspensions and compound dilutions were combined and incubated for 30 min at 37°C in a 5% CO2 humidified atmosphere, before the addition of LPS (or medium for non-LPS control samples). After the addition of LPS, plates were incubated for 2 h, followed by centrifugation to pellet cells. Cell supernatants were stored at 4°C until analysis for TNF-α content. TNF-α levels were determined by ELISA. Cytokine concentrations were determined.
