Table 4. IC50 of (±)-1, (+)-1, and (−)-1 on Human 92-1 Cells at 48 h.
IC50 values represent absolute estimates calculated with GraphPad Prism 5 for Windows using a nonlinear fit transform sigmoidal dose–response (variable slope). IC50 values are averaged from multiple determinations (n = 3).
Values are expressed as mean ± SD of four independent experiments, each conducted in triplicate.
