Abstract

Abstract: 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/cholesterol (2/l), and POPC/cholesterol (55/45), under isotonic and hypotonic (osmotically stressed) conditions. The activity of each surfactant has been defined by measuring its ability to release vesicle- ...
