| 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]. 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. |
