FIGURE 1.
Changes in RONS production induced by 5 and 6. Detection of the RONS production level was performed by DHR labeling. DHR mean fluorescence intensity in stained cells of C6, RC6, U87, and U87-TxR cell lines, treated with compounds 1, 2, 3, 4, 5, and 6 relative to untreated control (set at 100%, red line). All results are presented as percentages normalized to untreated control obtained from three independent experiments (n = 3).
