| IC50& Target[1] | |
体外研究
(In Vitro) | Pyrrophenone shows potent inhibition of arachidonic acid release, prostaglandin E2, thromboxane B2, and leukotriene B4formation 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 PCCl3cells[2].
Cell Proliferation Assay[2] | Cell Line: | PC-PTC3 and PCCl3cells | | 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 PCCl3cells was also inhibited by 0.5 μM, although to a lesser extent. |

体内研究
(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. |
