with bulky nitrogenous acceptor alcohols (triethanolamine, tris(hydroxymethyl)aminomethane, tetrakis(hydroxyethyl)ammonium) or the non-charged alcohols. Therefore, a strong dependence of the conversion of the monophosphatidyl to the diphosphatidyl compound on steric parameters and the head group charge was concluded. The enzyme-assisted strategy was used for the preparation of purified diphosphatidyldiethanolamine
由于其化学合成的复杂性,很难获得心磷脂(CL)和相关的二磷脂酰脂质。本文研究了链霉菌中磷脂酶D(PLD)的催化转磷酸化反应。sp。已被证明是合成新的CL类似物的另一种酶辅助策略。比较了由磷脂酰胆碱形成的这类化合物与一系列N-和C2-取代的乙醇胺衍生物以及不带电荷的醇(如甘油和乙二醇)的形成。具有低分子体积的乙醇胺衍生物(二乙醇胺和丝氨醇)可快速交换胆碱首基,可有效生产相应的CL类似物。相反,与大量的含氮受体醇(三乙醇胺,三(羟甲基)氨基甲烷,四(羟乙基)铵)或不带电荷的醇反应时,收率相对较低。所以,结论是,单磷脂酰向二磷脂酰化合物的转化对空间参数和头基电荷的强烈依赖性。酶辅助策略用于制备纯化的二磷脂酰二乙醇胺和二磷脂酰丝氨醇。
