Description

General description

Naturally occurring alkaloid. Cell-permeable, selective inhibitor of protein kinase C (IC₅₀ = 660 nM). Acts on the catalytic domain irrespective of the attachment of the regulatory domain. Material is a competitive inhibitor with respect to the phosphate acceptor and a non-competitive inhibitor with respect to ATP. Over ten-fold more potent than H-7, HCl (Cat. No. 371955). Inhibits thromboxane formation and phosphoinositide metabolism in platelets. Also induces apoptotic DNA fragmentation and cell death in HL-60 human promyelocytic leukemia cells.
