The crystal structures of acetylthiolcholine bromide and propionylthiolcholine iodide were elucidated. Acetylthiolcholine was found to be essentially isosteric with acetylselenolcholine, while the conformation of these compounds was quite different from that of acetylcholine. The importance of conformation and electron distribution in the biological actions of choline esters is discussed.
阐明了溴化乙酰硫代胆碱和碘化丙酰硫代胆碱的晶体结构。发现乙酰硫代胆碱与乙酰硒代胆碱基本等排,而这些化合物的构象与乙酰胆碱的构象有很大不同。讨论了胆碱酯生物活性中构象和电子分布的重要性。
