Calphostin C (UCN-1028C), a newly isolated compound from Cladosporium cladosporioides, is a potent and specific inhibitor of protein kinase C, because it was 1000 times more inhibitory to protein kinase C (IC50, 0.05 microM) than other protein kinases such as
H Ikemoto et al.
Journal of neurosurgery, 83(6), 1008-1016 (1995-12-01)
Calphostin C acts at the regulatory domain as a highly selective inhibitor of protein kinase C (PKC), and staurosporine acts at the catalytic domain as a nonspecific PKC inhibitor. The authors investigated the capacity of calphostin C and staurosporine to
I Ozaki et al.
The Journal of biological chemistry, 274(9), 5310-5317 (1999-02-20)
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
Yang Chen et al.
Annals of translational medicine, 10(3), 132-132 (2022-03-15)
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
R F Bruns et al.
Biochemical and biophysical research communications, 176(1), 288-293 (1991-04-15)
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.
