A series of wedge-shaped, nonionic surfactant molecules (molecular harpoons) have been synthesized and used to disrupt large unilamellar vesicles derived from 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), POPC/cholestcrol (2/1), and POPC/cholesterol (55/45), under isotonic and hypotonic (osmotically stressed) conditions. The activity of each surfactant has been defined by measuring its ability
已经合成了一系列楔形非离子表面活性剂分子(分子鱼叉)并用于破坏源自 1-棕榈酰-2-油酰-sn-甘油-3-磷酸胆碱 (POPC)、POPC/胆固醇 (2 /1) 和 POPC/胆固醇 (55/45),在等渗和低渗(渗透压力)条件下。已通过测量其释放囊泡包裹的 5(6)-羧基荧光素 (CF) 的能力来定义每种表面活性剂的活性。还进行了比较研究,使用 Triton X-100 作为破坏剂
