N-allyl-BS and N-(3-mb)-BS respectively inhibit viability of DU 145 (A,B) and PC-3 (C,D) prostate cancer cells in a dose dependent manner, while normal prostate cells PNT1A (E,F) are more resistant. The cells were treated with indicated concentrations of N-allyl-BS or N-(3-mb)-BS for 24 h. Viability was determined using SRB assay. Data are presented as mean ± SE (n = 3); significance of variation was calculated using one-way ANOVA followed by Dunnett’s multiple comparison test. (* P < 0.01) (** P < 0.001).
