Teleocidin A1
Non-phorbol ester PKC activator / Teleocidin A1 is a selective protein kinase C activator1 (EC50 = 40 ng/ml) representing a new class of non-phorbol ester tumor promotor2. Teleocidin A1 mimics the effect of diacylglycerol (DAG), activating PKC, but unlike DAG causes persistent activation.3 It enhances actin redistribution, vacuole formation and c-fos expression in PLC/PRF/5 hepatoma cells.4 Occurs in toxic cyanobacterial blooms.5
