ζ-Stat trisodium (NSC37044 trisodium) is a potent and selective inhibitor of protein kinase C-ζ (PKC-ζ), exhibiting an IC50 of 5 μM. It effectively suppresses the proliferation of melanoma cell lines and promotes apoptosis. Moreover, ζ-Stat trisodium demonstrates notable antitumor activity in vitro.

Ruboxistaurin is a PKC beta inhibitor. Ruboxistaurin reduces oxidative stress and attenuates left ventricular hypertrophy and dysfunction in rats with streptozotocin-induced diabetes. Ruboxistaurin attenuates diabetic nephropathy via modulation of TGF-β1/

Protein kinase C (PKC) activator

Cercosporamide is a ATP-competitive Pkc1 kinase inhibitor (IC50 <50 nM; Ki <7 nM). It also is a unique Mnk inhibitor.

N-Myristoyl-Lys-Arg-Thr-Leu-Arg 是一种蛋白激酶 C (PKC) 抑制剂，其 IC50值为 75 μM。N-Myristoyl-Lys-Arg-Thr-Leu-Arg 抑制人白血病细胞系 Jurkat 中 IL-2受体的诱导和 IL-2的产生。

Protein Kinase C (19-35) Peptide 是PKC 假底物抑制剂/区域。Protein Kinase C (19-35) Peptide 阻断PKC 激酶结构域的底物结合位点，使PKC 的细胞质形式失活。
