Use of Calphostin C

Calphostin C is a potent and specific inhibitor of protein kinase C. Calphostin C is an antitumor antibiotic. Calphostin C has 1000 times more inhibitory to protein kinase C with an IC50 of 0.05 μM than other protein kinases. Calphostin C induces apoptosis in some tumor cell lines. Calphostin C has potent cytotoxic activity and antitumor activity[1].

Activation of peroxisome proliferator-activated receptor-γ (PPARγ) by thiazolidinediones lowers blood pressure, whereas PPARγ mutations cause hypertension. Previous studies suggest these effects may b...

Impairment of neurovascular coupling in type 1 diabetes mellitus in rats is linked to PKC modulation of BK(Ca) and Kir channels.
