Administration of phorbol 12-myristate,13-acetate (PMA, 10 fmol-10 nmol) or phorbol 12,13-dibutyrate (PDB, 0.2-495 nmol) (i.c.v.) to mice induced: hindlimb scratching, tremor, myoclonic jerks, hyperlocomotion, clonic seizure, followed by death or recovery. CD50 values for clonic seizures for PMA and PDB were 1.0 pmol and 1.2 nmol. 4-alpha-Phorbol (68-686 nmol) was inactive. The effects of PDB (24-247 nmol) were reduced by pretreatment with staurosporine (30 nmol, i.c.v.). Protein kinase C activators are potent convulsants in vivo.
向小鼠脑室内注射佛波醇12 -肉豆蔻酸酯13 -乙酸酯（PMA，10飞摩尔 - 10纳摩尔）或佛波醇12,13 -二丁酸酯（PDB，0.2 - 495纳摩尔）会引发：后肢抓挠、震颤、肌阵挛性抽搐、运动亢进、阵挛性惊厥，随后导致死亡或恢复。PMA和PDB引发阵挛性惊厥的半数惊厥剂量（CD50）值分别为1.0皮摩尔和1.2纳摩尔。4-α-佛波醇（68 - 686纳摩尔）无活性。用星形孢菌素（30纳摩尔，脑室内注射）预处理可降低PDB（24 - 247纳摩尔）的作用。蛋白激酶C激活剂在体内是强效惊厥剂。
