2-二甲氨基乙醇用相应的脂醯氯醯化后得到的叔胺再用碘甲烷季铵化,合成了一系列晶体的胆碱脂酸酯氢碘酸盐,其中并包括了两个不饱和脂酸酯.在这系列化合物中,短链的化合物对神经系统的作用与乙醯胆碱相仿,但长链化合物却抑制了乙醯胆碱的作用.致谢:本文大部分实验工作系在英国 Birmingham 大学药理系所作,作者对 A.C.Frazer教授的鼓励与协助致谢. The 2-dimethylaminoethanol with the corresponding esterification of acenaphthene, followed by quaternization with methyl iodide, gave a series of crystals of cholinestearate hydroiodide, which included two Saturated fatty acid esters.In this series of compounds, short-chain compounds on the nervous system role and acetylcholine, but long-chain compounds inhibit the role of acetylcholine.
