coniineとは 意味・読み方・使い方

Coniine is a poisonous alkaloid found in poison hemlock and the yellow pitcher plant, and contributes to hemlock's fetid smell. It is a neurotoxin which disrupts the peripheral nervous system. It is toxic to humans and all classes of livestock; less than 0.2g is fatal to humans, with death caused by respiratory paralysis. Socrates was put to death by way of this poison in 399 BC. Coniine has two stereoisomers: (S)-(+)-coniine (CAS 458-88-8), which is the natural isomer present in hemlock and (R)-(-)-coniine (CAS 5985-99-9). Coniine was first synthesized by Albert Ladenburg in 1886; it was the first of the alkaloids to be synthesized.
