What is described is a process for preparing lysophosphatidylcholine by selective monoacylation of glycerophosphorylcholine (I), in the presence of an acylating agent and of dialkyltin derivatives, according to the following diagram:
the process being particularly simple and having high overall yields.

supplemented with propranolol. This isolation of lipidated drug molecules from liver cells demonstrates a new drug reactivity in living systems. Acyl transfer from lipids to the alcoholic group of propranolol was favoured over transfer to the secondary amine. Migration of acylgroups from the alcohol to the amine was diminished. Other drugs that were examined did not form detectable levels of lipidation products
普萘洛尔被证明在三种类型的脂膜中发生脂化反应:(1)合成单组分甘油磷脂脂质体;(2)由从大肠杆菌或肝细胞中提取的复杂脂质混合物形成的脂质体;(3) Hep G2 细胞中的纤维素。在补充普萘洛尔的培养基中培养的 Hep G2 细胞的提取物中鉴定出 14 种不同的脂化普萘洛尔同系物。从肝细胞中分离脂质化药物分子证明了生命系统中的新药物反应性。酰基从脂质转移到普萘洛尔的醇基团比转移到仲胺更有利。酰基从醇到胺的迁移减少。所检查的其他药物没有形成可检测水平的脂化产物,但其中许多药物确实影响模型膜中的溶血脂水平。人们发现,化合物在模型系统中诱导溶血脂形成的倾向是纤维素中磷脂沉积活性的预测因子。

Lysophosphatidylcholine (LPC) and phosphatidylcholine (PC) are important membrane constituents implicated in signaling and immune regulation. Synthesis of LPCs is challenging due to rapid acyl migration, e.g., induced by chromatography. We here report a highly regioselective synthesis of LPC and mixed PC via an intermediate allowing specific terminal acyl introduction, yielding the pure LPC without

other important amineoxidases in the plasma, namely monoamineoxidase (MAO) A and B and diamine oxidase (DAO). For a series of ω-(5-phenyl-2H-tetrazol-2-yl)alkan-1-amine substrates similar conversion rates were measured for both the purified PAO and crude plasma. The inhibition values determined for the PAO inhibitor 2-(4-phenylphenyl)acetohydrazide (16) under different conditions also corresponded
