  • n. 紅豆堿

  • 專業解析

    Abrine(阿布裡堿)是一種天然存在的生物堿,主要存在于毒扁豆(Physostigma venenosum) 的種子中。以下是其詳細解釋:

    1. 化學本質與結構

      Abrine屬于吲哚類生物堿。其化學名稱為N-甲基色氨酸(N-Methyltryptophan)。這意味着它的核心結構是氨基酸色氨酸(Tryptophan),其中一個氫原子被甲基(-CH₃)取代,具體位置在色氨酸的α-氨基(-NH₂)上,形成了N-甲基化結構。其分子式為C₁₂H₁₄N₂O₂。

    2. 來源

      它最著名的來源是西非的豆科植物毒扁豆(又稱卡拉巴豆,Calabar bean)。這種植物以其強烈的毒性而聞名,其種子中含有多種生物堿,其中最主要的毒性成分是毒扁豆堿(Physostigmine),而Abrine是其中存在的其他生物堿之一。

    3. 生物活性與毒性

      • 神經毒性:Abrine本身具有一定的神經毒性。它與色氨酸結構相似,可能幹擾依賴于色氨酸的生化過程。有研究表明它可能抑制某些酶的活性或幹擾神經遞質功能。
      • 潛在研究價值:由于其結構特點和生物活性,Abrine在生物化學和藥理學研究中曾被用作工具化合物,用于研究氨基酸代謝、蛋白質合成或神經系統的功能。例如,它曾被用來研究氨基酸轉運機制。
      • 與蓖麻毒素的關系:需要特别注意的是,Abrine與蓖麻毒素(Ricin)完全不同。蓖麻毒素(Ricin)是一種劇毒蛋白質,來源于蓖麻籽(Ricinus communis),作用機制是抑制蛋白質合成。兩者名稱相似(英文名Abrine和Ricin),來源不同(毒扁豆 vs 蓖麻籽),化學本質(小分子生物堿 vs 大分子蛋白質)和毒性機制也截然不同,極易混淆。Abrine的毒性遠低于蓖麻毒素。
    4. 名稱與詞源

      “Abrine”這個名稱可能源于其來源植物毒扁豆的舊屬名Abrus(現在該植物屬于Physostigma屬),或者與該植物在西非的當地名稱有關。這反映了早期植物化學研究中以來源植物命名化合物的慣例。
