In Vitro：

ζ-Stat (0.1-20 µM) shows only 13% inhibition on PKC-ι at 20 μM, but shows a significant inhibition on PKC-ζ as 51% at 5 μM level.

ζ-Stat (0.1-10 µM; 3 d) significantly decreases cell proliferation of SK-MEL-2 and MeWo upon increasing the concentrations.

ζ-Stat (7 or 10 µM; 24-72 h) and 5-FU in combination is able to decrease the viability of LoVo CRC cells by more than 75%.

ζ-Stat (5 µM; 3 d) shows a significant diminution of phosphorylated, total PKC-ζ, Bcl-2 and PARP levels, and increases Caspase-3 and cleaved-PARP levels in SK-MEL-2 and MeWo cells.

ζ-Stat (5 µM; 1-10 h) does not show significant cytotoxicity on MEL-F-NEO, SK-MEL-2 and MeWo cells.
