Figure 1. The structure of PPMP and its effect on viability of esophageal cancer cells.

Figure 1

(A) Chemical structure of PPMP. Viability of human esophageal cancer cells was estimated by MTS assay in (B) KYSE30, (C) KYSE450, and (D) KYSE510 cancer cells. All esophageal cancer cells were treated for 48 h with various concentrations of PPMP. Data are shown as mean values ± S.D. from 3 independent experiments conducted with triplicate samples. Statistical significance was determined by the Student's t-test (*p < 0.05 vs. untreated group).
