The invention relates to compounds having the formula:
wherein R₁ is H or an acyl group having 1-12 carbon atoms,
R₂ and R₃ are an alkyl or aralkyl group having 1-12 carbon atoms, or when taken together form with the nitrogen atom a heterocyclic amino radical; and R₄ is H or an acyl group having 1-12 carbon atoms; and mono- or bisquaternary ammonium compounds thereof and acid addition salts of the non- or mono-quaternary ammonium compounds and to a process for preparing these compounds. The compounds are neuromuscular blocking agents with a fast onset and a short duration and which exhibit no or hardly any blood pressure drop.
本发明涉及具有以下式子的化合物:
其中 R₁ 是 H 或具有 1-12 个碳原子的酰基、
R₂和 R₃ 是具有 1-12 个碳原子的烷基或芳烷基,或与氮原子一起形成杂环
氨基;以及 R₄ 是 H 或具有 1-12 个碳原子的酰基;及其单季
铵或双季
铵化合物和非单季
铵或单季
铵化合物的酸加成盐,以及制备这些化合物的工艺。这些化合物是起效快、持续时间短的神经肌肉阻断剂,不会或几乎不会出现血压下降。
