Figure 4. Quantitative assessment of cytotoxic effects of curcumin and compound 2 on murine microglial cells.

Cultured microglial cells were incubate without or with the indicated concentrations of curcumin or compound 2 for 24 h. Cells were then incubated with Wst-1 reagent for 1 h, afterwhich absorbance was measured (460 nm). Values on graph represent mean values calculated from triplicate experimental points. Standard deviations from mean values were determined as <5% for each experimental point.
