| Description | PF-9184 is a potent and selective inhibitor of human microsomal prostaglandin E synthase-1 (mPGES-1) with an IC50 of 16.5 nM, and it inhibits IL-1β-induced PGE2 synthesis in vitro. |
| In vitro | PF-9184 (0.015-100 μM; 24 hours) inhibits IL-1β-stimulated prostaglandin E2 (PGE2) synthesis in synovial fibroblasts derived from rheumatoid arthritis (RASF) patients with no apparent cytotoxic effects. It potently blocks mPGES-1's ability to synthesize PGE2 from PGH2 without inhibiting COX-2 and prostacyclin synthase in cells. In human whole blood and modified blood assays, PF-9184 weakly inhibits PGE2 and affects TXB2 synthesis only at 100 μM. PF-9184 poorly inhibits recombinant rat mPGES-1 (IC50=1080±398 nM)[1]. |
| In vivo | PF-9184, whether administered orally or locally, does not affect PGE2 synthesis in recombinant rats[1]. |

DMSO
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
