Highly specific inhibitor of protein kinase C (IC50 = 50 nM); requires light for activation. At higher concentrations (100 nM or greater), it has been shown to inhibit cell proliferation and induce apoptosis in vitro.

Protein kinase C (PKC) is a central component in signal transduction and growth control and might be an appropriate target for the chemotherapy of human brain tumors. This study demonstrates that the staurosporine derivative Ro 31-8220, a potent PKC inhibitor
Potent and specific inhibitors of protein kinase C have been found in streptomyces and fungi: Staurosporine, an alkaloid from Streptomyces sp., is the most potent inhibitor of protein kinases with an IC50 in the nanomolar range. UCN-01 (7-hydroxy staurosporine), isolated

Calphostin C, a secondary metabolite of the fungus Cladosporium cladosporioides, inhibits protein kinase C by competing at the binding site for diacylglycerol and phorbol esters. Calphostin C is a polycyclic hydrocarbon with strong absorbance in the visible and ultraviolet ranges.

The currently available treatment methods are ineffective in reducing mortality or improving outcomes in acute lung injury (ALI). The activation of protein kinase C alpha (PKCα) has recently been implicated in ALI development. We explored the potential therapeutic outcomes of

Apoptosis was induced in human glioma cell lines by exposure to 100 nM calphostin C, a specific inhibitor of protein kinase C. Calphostin C-induced apoptosis was associated with synchronous down-regulation of Bcl-2 and Bcl-xL as well as activation of caspase-3
