LY379196 is a highly specific PKCβ inhibitor with IC50 of 30-50 nM for PKCβI and PKCβII.

BJE6-106 (B106)?is a potent, selective PKCδ inhibitor with IC50 of 50 nM, displays excellent selectivity over classical PKC isozymes.

Selective cell-permeable peptide inhibitor of protein kinase C (IC50 ~ 0.5 μM). Consists of amino acids 19 - 31 of PKC pseudosubstrate domain linked by a disulphide bridge to a cell permeabilisation Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the inhibitor peptide. Once inside the cell, the disulphide bonds are subjected to reduction in the cytoplasm leading to release of the inhibitor peptide.
