Effects of curine and guattegaumerine on the proliferation of HTC-R cells. The cells were grown in 24-well plates in the absence (control) or presence of concentrations of the curine and guattegaumerine indicated in abscissas. After 36 h of incubation, the percentage of living cells was calculated. Experiments were carried out three times in triplicate. Values represent the mean percentage of living cells ± standard deviation.
