The effect of various concentrations of target compounds on HeLa cell proliferation. Cells were treated with various concentrations of compounds (A) 0.1 mmol/L (B) 0.5 mmol/L (C) 1 mmol/L (D) 2 mmol/L for 48 hours and the relative cell viability was determined by MTT. The values are expressed as mean ± SD of three determinations. * p < 0.05, compared with Trp. ** p < 0.01, compared with Trp. # p < 0.01, compared with any other group.
