Abstract

N-(6-Phenylhexyl)-5-chloro-1-naphthalenesulfonamide (SC-9) activated Ca2+-activated, phospholipid-dependent protein kinase (protein kinase C). SC-9 acted as a substitute for phosphatidylserine, which is one of the endogenous factors in activating protein kinase C. SC-9 was also effective in regulating the physiological functions at the whole-cell level. For example, SC-9 stimulated hexose transport activity in mouse fibroblasts, a protein kinase C-regulated cellular function. Thus, SC-9 may be useful to study the molecular basis of the regulation of protein kinase C activity, and the biological significance of this enzyme.
