l (11) and (R)-2-O-benzyl-1-O-tert-butyldiphenylsilylglycerol (12), respectively, as key intermediates. With respect to the surface properties and the aggregation behavior, the drug-phospholipid conjugates resembled natural phosopholipids. Upon incubation with porcine pancreatic phospholipase A(2), only compounds with a fatty acid in the sn-2 position of the glycerol backbone were degraded. Derivatives
本研究的目的是合成包含药物分子而不是脂肪酸的磷脂。丙戊酸和布洛芬用作模型化合物。从sn-甘油-3-磷酸胆碱(1)或使用(S)-2-O-苄基-1-O-三苯甲基甘油(11)和(R)-2-O-苄基-1合成目标分子-O-叔丁基二苯基甲硅烷基甘油(12)分别作为关键中间体。关于表面性质和聚集行为,药物-磷脂缀合物类似于天然的磷脂。与猪胰磷脂酶A(2)孵育后,只有甘油骨架的sn-2位置具有脂肪酸的化合物才被降解。布洛芬在sn-2位置或显示出非天然S构型的衍生物均对酶促体外水解具有抗性。
