PBISe IC50 (μmol/L) values for melanoma cell lines

Cell linePBITPBISePEITPEIS
WM115>1009.7 ± 1.4>100∼80

  • NOTE: IC50 values show that PBISe but not PBIT or the corresponding monosubstituted PEISe or PEIT is effective at inhibiting melanoma cell viability at concentrations 10-fold lower than PBIT.
