  • 人类毒性摘录
人类暴露研究/ 仅摄入Cicuta甜味根部的2厘米部分就可能导致致命的癫痫持续状态;一个孩子将茎当作玩具哨子使用导致了孩子的死亡。癫痫发作的原因尚不清楚,但可能与中枢胆碱能过度兴奋、钠通道效应或钾依赖通道的阻断有关。
/HUMAN EXPOSURE STUDIES/ Ingestion of as little as a 2 cm section of the sweet-tasting root of Cicuta can produce fatal status epilepticus; a child's use of a stem as a toy whistle caused the child's death. The cause of seizures is not clear but may be from central cholinergic overstimulation, sodium channel effects, or blockade of potassium dependent channels.

    摘要:
    属于伞形科的铁杉(Cicuta virosa)是一种有毒植物,众所周知,是一种有毒植物,可导致人类和动物致命中毒,导致滋补和阵挛性抽搐和呼吸麻痹。Cicutoxin(1)是植物的主要暴力毒素,是C(17)-聚乙炔类的化学物质,在其结构中具有长pi键共轭系统,末端羟基和烯丙基羟基,并且已从植物中分离出多种类似物。在本研究中,这些毒素的各种衍生物是通过西妥昔因(1)和病毒A(3)和B(4)的乙酰化,甲基化和氧化合成的。通过在Sonogashira的条件下将(7S)-dodeca-3,5-dien-1-yn-7-ol和1-iodopentyne偶联制备1-Dehydroxyvirol A(28)。还通过(5S)-1-氯癸-1,3-二烯-5-醇和1-碘戊炔-5-醇的偶联制备单炔化合物(29)。研究了西葫芦毒素衍生物对小鼠的急性毒性所涉及的构效关系,发现π键结合的长度和几何形状以及O-官能团对活性很
