General description

The liposomal entrapment of 1,5-naphthalenedisulfonic acid disodium salt in phospholipid vesicles has been studied. Doubly substituted aromatic dianions of 1,5-naphthalenedisulfonic acid disodium salt has been investigated by collision-induced dissociation, along with infrared multiple photon dissociation/detachment techniques.

The liposomal entrapment of suramin and similar compounds in phospholipid vesicles was examined. For dipalmitoylphosphatidylcholine (DPPC) liposomes, entrapment percentages ranged from 25 to 65% with 3-25 mM phospholipid for aqueous solutions containing 0.07 mM of suramin. Incorporation of 30-50 mol
