The calmodulin antagonist N(6-aminohexyl)-5-chloro-1-naphthalene-sulfonamide (W-7) has been examined as an inhibitor of superoxide anion production and granule exocytosis in phorbol ester (PMA)-activated neutrophils. Inhibition of the respiratory burst was observed at a concentration of W-7 identical to that required for inhibition of native protein kinase C (PKC), whereas the concentration required to inhibit the secretory response was found to correspond to that required for inhibition of the proteolytically converted fully active PKC. The IC50 of W-7 was in both cases 5 and 12 fold higher than that required for inhibition of calmodulin dependent kinases. The results confirm the essential role for the membrane-bound PKC in the production of O2- radicals and provide a clear evidence of the direct participation of the proteolytically activated cytosolic PKC to the secretory response of PMA activated neutrophils.
