Figure 1.

Variable levels of NO produced by furoxan/OA hybrids selectively in HCC cells. Individual values were obtained by subtracting the background (diluent treated wells) and calculated according to the standard curve. Data shown are the mean value of two experiments for each compound at 240 min post-treatment, and similar patterns of nitrate/nitrite levels in HCC cells were observed at other experimental time points (data not shown).
