专业解析

去甲莨菪硷 (Norhyoscyamine) 是一种重要的天然托品烷类生物碱，其详细解释如下：

1. 定义与化学本质
   • 中文名： 去甲莨菪硷
   • 英文名： Norhyoscyamine
   • 化学本质： 它是莨菪硷 (Hyoscyamine) 的天然去甲基代谢产物或前体物质之一。其化学结构与莨菪硷高度相似，区别在于莨菪硷分子中的氨基氮上连接的是甲基 (-CH₃)，而去甲莨菪硷连接的是氢原子 (-H)。其化学式为 C₁₆H₂₁NO₃。
   • 结构特征： 属于托品烷衍生物，具有手性中心，通常以消旋体形式存在（即阿托品 Atropine 的去甲基类似物），但生物活性主要归因于其左旋异构体（L-Norhyoscyamine）。其结构式为： $$ ce{ O || C-O-CH-CH2- quad | quad N-CH-CH2-CH2- quad | quad CH2-CH-CH- quad | quad OH quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad quad

网络扩展解释

关于“去甲莨菪硷”这一名称，目前公开的权威资料中未见明确记载，可能存在以下情况需注意：

1. 名称准确性
   “莨菪硷”是“莨菪碱”的旧称（“硷”为“碱”的旧写法），而“去甲”通常指化学结构中去掉一个甲基（-CH₃）。常见的莨菪碱类化合物包括阿托品（Atropine）、东莨菪碱（Scopolamine）和山莨菪碱（Anisodamine），但“去甲莨菪碱”并非标准命名。

2. 可能的混淆或错误

   • 若指山莨菪碱（Anisodamine），其别名“654-2”常用于缓解平滑肌痉挛或改善微循环。
   • 若涉及“去甲基化”，可能指某类莨菪碱衍生物，但需具体结构式或文献支持。

3. 建议

   • 确认名称拼写或提供更多化学结构信息。
   • 参考权威药典（如《中国药典》）或专业数据库（如PubChem）进一步查询。

若有其他背景信息，可补充说明以便更精准解答。
