ζ-Stat

ζ-Stat (NSC37044) is a specific and atypical PKC-ζ inhibitor, with an IC₅₀ of 5 μM. ζ-Stat can reduce melanoma cell lines proliferation and induce apoptosis, and has antitumor activity in vitro^[1][2]. IC50 & Target: IC50: 5 μM (PKC-ζ)^[1] 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^[1].
ζ-Stat (0.1-10 µM; 3 d) significantly decreases cell proliferation of SK-MEL-2 and MeWo upon increasing the concentrations^[1].
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^[1].
ζ-Stat (5 µM; 1-10 h) does not show significant cytotoxicity on MEL-F-NEO, SK-MEL-2 and MeWo cells^[1].
