翠雀碱delphinine)是一种有毒的二萜生物鹼,存在于翠雀属除虱草属铁线莲属植物中[1]。翠雀鹼是在除虱草種子中發現的主要生物鹼之一。[2]它在結構與作用上與烏頭鹼相似,作為電壓門控鈉通道英语voltage gated sodium channels變構調節劑英语allosteric modulator[3]並產生低血壓心動過緩心律失常。這些影響使其具有劇毒(LD50 1.5–3.0 mg/kg兔子和狗;青蛙的易感性約為10倍)[4]。雖然它已被用於一些替代藥物(例如草藥[5][6]),大多數醫學界不建議使用它,因為它具有極高的毒性。

Isolation

[编辑]
已隱藏部分未翻譯内容,歡迎參與翻譯

One of the earliest reports of the isolation of delphinine, from D. staphisagria, was that of the French chemists Lassaigne and Feneulle, in 1819.[7] A less antique and more accessible report is that of the USDA chemist L. N. Markwood, who also briefly reviewed the earlier isolation work.[8] Notably, these early isolations were carried out without the aid of chromatography, since delphinine crystallizes readily from a petroleum ether extract after the typical acid-base cycling used in traditional plant alkaloid-extraction methods.[9]

化學

[编辑]

儘管翠雀鹼相對容易分離,但直到 1970 年代初,它的分子結構才以目前公認形式確立。當時,威斯納的研究小組將C-1處的甲氧基的立體化學從β-修正為α-分子構型[10][11]因此,任何出現在 1971-1972 年之前的翠雀鹼分子圖都可能在 C-1 處顯示不正確的立體化學。

藥理

[编辑]

由於它的早期發現和結晶形式的分離(當時被認為是純度標準),儘管事實上其分子結構未知,但在19世紀,翠雀鹼藥理特性得到廣泛研究。其中一些調查很可能是用不純的藥物進行的,應該謹慎解釋。在Benn和Jacyno的評論中可以找到對這些早期研究的參考和評論。[4] 最近的研究集中在翠雀鹼的心血管毒性上。[12][13]

一般來說,翠雀鹼的藥理學似乎類似於烏頭鹼,儘管翠雀鹼的急性毒性似乎低於烏頭鹼在試驗動物中的毒性。[4]
