Cell permeable potent inhibitor of protein kinase C. Does not inhibit tyrosine protein kinases, cAMP-dependent protein kinase or calcium/calmodulin-dependent protein kinase. Antiplatelet, anti-inflammatory, antibacterial and antitumor compound. Apoptosis inducer in cancer cells in vitro and in vivo. Activates MAPK and JUNK signaling pathways. Affects translocation of PKC from cytosol to plasma membrane . Neurite outgrowth stimulator. Inhibits binding of BclXL to Bak (IC50 = 1.5 M) or Bad proteins and stimulates apoptosis in several cancer cell lines. Blocks human P2X7 receptor. Induces cell cycle arrest in G1 phase. Specific cyclooxygenase-2 inhibitor.
