    Description

    Pyrrophenone is a potent and specific cytosolic phospholipase A2α (cPLA2α) inhibitor with an IC50 value of 4.2 nM[1].

    IC50 & Target[1]

    cPLA2α

    4.2 nM (IC50)

    In Vitro

    Pyrrophenone shows potent inhibition of arachidonic acid release, prostaglandin E2, thromboxane B2, and leukotriene B4 formation in human whole blood[1].
    Pyrrophenone inhibits the production of arachidonic acid (AA) (IC50=24±1.7 nM), PGE2 (IC50=25±19 nM),, and LTC4 (IC50=14±6.7 nM),from THP-1 cells stimulated with A23187[1].
    Pyrrophenone inhibits the production of AA (IC50=0.19±0.068 μM), PGE2 (IC50=0.20±0.047 μM), TXB2 (IC50=0.16±0.093 μM),and LTB4 (IC50=0.32±0.24 μM) from human whole blood stimulated with A23187[1].
    Pyrrophenone (0.1-0.5 μM, 48 h) inhibits the growth of PC-PTC3 and PCCl3 cells[2].

    Cell Proliferation Assay[2]

    Cell Line: PC-PTC3 and PCCl3 cells
    Concentration: 0.1, 0.3, and 0.5 μM
    Incubation Time: 48 hours
    Result: Significantly inhibited basal PC-PTC3 cell proliferation at concentrations as low as 0.1 μM.
    Basal cell proliferation of normal PCCl3 cells was also inhibited by 0.5 μM, although to a lesser extent.
    In Vivo

    Pyrrophenone (administered i.p. at 20 mg/kg 30 min before LPS injection.) suppresses bronchoalveolar lavage (BAL) levels of leukotriene B4 (LTB4) and platelet activating factor (PAF)[3].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Specific pathogen-free female BALB/c mice[3]
    Dosage: 20 mg/kg
    Administration: Administered i.p. 30 min before LPS injection
    Result: Suppressed the recruitment of neutrophils and eosinophils, but not macrophages.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
