解説
テバイン.アヘンアルカロイドの一つ.コデインから誘導される.融点193 ℃.[α]D-219°(エタノール).水に微溶,エタノール,エーテルに易溶.麻酔作用は弱く,むしろストリキニーネ様のけいれんを起こすので,医薬とはしない.鎮痛作用をもつほかの誘導体の合成原料として用いられる.LD50 14 mg/kg(ウサギ,皮下注).
説明
The naturally occurring opiate alkaloid thebaine is
present in high concentrations in poppy straw; lower
concentrations of the co deine alkaloid are present.
化学的特性
Tan Solid
使用
Thebaine is present in opium at 0.3–1.5%.It is extracted from opium or from latex ofthe plant Papaver bracteatum, in which it ispresent at up to 26%. It is used to producecodeine.
危険性
Toxic by ingestion, may induce addiction.
健康ハザード
Although thebaine has a morphine- orcodeine-like structure, its pharmacologyaction is somewhat different. It is a convulsantpoison like strychnine, rather thana narcotic. High doses can cause ataxia andconvulsion
LD50 value, intraperitoneal (mice): 42 mg/kg
Thebaine is a habit-forming compound. Itis a controlled substance (opiate) listed underU.S. Code of Federal Regulations (Title 21Part 1308.12, 1985).
接触アレルゲン
The naturally occurring opiate alkaloid thebaine is present in concentrated poppy straw, and in small concentrations in codeine alkaloid. It is used in the manufacture of other opiate pharmaceuticals, such as buprenorphine and morphine, and caused contact dermatitis in a laboratory worker at an opiates manufacturing pharmaceutical company, also sensitive to codeine.
純化方法
Crystallise Thebaine from Et2O or EtOH. Sublime it at 170-180o. The hydrochloride decomposes >182o (from MeOH/Et2O). [Beilstein 27 II 177, 27 III/IV 2271.] It is a NARCOTIC.
