Dose-dependent effects of ascending amounts of β-PQA salts against MCF-7 cancer cell lines on the percentage inhibition of cell proliferation. (A) MCF-7 cells were treated with compound 4a for 24 h. (B) MCF-7 cells were treated with compound 4b for 24 h. (C) MCF-7 cells were treated with compound 4c for 24 h. (D) MCF-7 cells were treated with compound 4d for 24 h. (E) MCF-7 cells were treated with compound 4e for 24 h. (F) MCF-7 cells were treated with compound 4f for 24 h. Dunnett’s multiple comparisons test was used to analyze the difference between the treatment group and the control group, (**) p < 0.01.
