Table 2. Half-Maximal Inhibitory Concentrations (IC50/μM) of Pt1, Pt2, and Cisplatin toward PC3 Cancer Cells in the Dark and on Exposure to Blue Light, and Standard Deviations from Duplicates of Triplicate Determinationsa.
complex | dark IC50b (μM) | photo IC50c (μM) |
---|---|---|
Pt1 | >100d | 55.6 ± 0.9 |
Pt2 | >100d | 6.48 ± 0.84 |
cisplatin | >100d | >100d |
100 μM concentration (higher than the test range) is deemed inactive.
1 h exposure to complexes to allow uptake (protected from light) followed by a further 1 h protected from light and 24 h recovery in fresh medium.
1 h exposure to complexes to allow uptake (protected from light) followed by 1 h irradiation with blue light (λ = 465 nm, 17 J/cm2) and 24 h recovery in fresh medium.
Exceeds the concentration range used for IC50 determination.
