Fig. 1. Chemical structure and anti-inflammatory activity of SCT. (A) Molecular structure of SCT. (B) RAW-264.7 cells (1×10⁶ cells/ml) were pretreated with SCT (left panel) or L-NAME (right panel) for 1 h and incubated with LPS (1 µg/ml) for 24 h. The nitric oxide levels were measured by the Griess assay. (C) Viability of RAW264.7 cells after treatment with SCT for 24 h. Viability was determined by a conventional MTT assay. ^*p<0.05 and ^**p<0.01 compared with the control group.
