Effects of KHU14 on cell viability and iNOS and COX-2 expression in RAW264.7 cells. (A) Cell viability. (B) Western blot. RAW264.7 cells were treated with 0, 1, 10, 100, 200 μg/ml of KHU14 dissolved in DMSO one hour before stimulated with LPS (1 μg/ml) for 72 hours for measurement of cell viability. For western blot analysis, cells were stimulated with LPS for 24 hours in the presence of KHU14. The results are expressed as mean and SD.
