Calphostin C
Based on 2 publication(s) in Google Scholar
Calphostin C is a highly selective PKC inhibitor (IC50=0.05 μM) and tumor apoptosis inducer. Calphostin C competitively binds to PKC and inhibits PKC-mediated phosphorylation signal transduction. Calphostin C restores Na+/K+ ATPase activity in the sciatic nerve of diabetic mice and improves neuropathy. Calphostin C can be used in the study of anti-tumor and diabetic complications.

Calphostin C blocks the binding of [3H]PDBu to PKC and inhibits its activation process with IC50=0.03 μM[1].
Calphostin C (5 μM; 10 min-6 h) induces apoptosis in NALM-6 leukemia cells[2].
Calphostin C (2 μM; 24 h) is metabolized to inactive Calphostin B by esterases, and Calphostin B is not toxic to NALM-6 cells[2].

Calphostin C (1 μg/kg and 10 μg/kg; i.p.; single dose) restores the sciatic nerve Na+/K+ ATPase activity to normal levels in a streptozotocin (STZ)-induced diabetic mouse model[3].
Calphostin C (50 μg/mL; continuous administration by mini-osmotic pump; 0.5 μL per day; 2 weeks) restores the sciatic nerve Na+/K+ ATPase activity to normal levels in diabetic mice without affecting blood glucose levels[3].
