ζ-Stat trisodium (NSC37044 trisodium) is a specific and atypical PKC-ζ inhibitor, with an IC50 of 5 μM. ζ-Stat trisodium can reduce melanoma cell lines proliferation and induce apoptosis, and has antitumor activity in vitro[2].IC50 & Target: IC50: 5 μM (PKC-ζ)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%[2].
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.
