合成了两个烷基末端均含有2-硝基苄酯的光不稳定磷脂酰胆碱(PLPC)。酯的光解在PLPC膜的疏水区域中产生羧酸根离子,导致如通过相差显微镜观察到的PLPC脂质体的瞬时崩解。紫外线照射后,包埋的大分子(45-kdalton卵清蛋白)从PLPC脂质体释放。
Photo-labile phosphatidylcholine (PLPC) was synthesized which contains 2-nitrobenzyl esters at the terminals of both alkyl chains. Photolysis of the esters generates carboxylate ions in the hydrophobic region of the PLPC membrane, leading to instant disintegration of PLPC liposomes as observed by the phase contrast microscopy. Upon UV irradiation, entrapped macromolecules (45-kdalton ovalbumin) were released from PLPC liposomes.
