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.

Collision-induced dissociation (CID), along with infrared multiple photon dissociation/detachment (IRMPD) techniques, is utilized to study a series of doubly substituted aromatic dianions containing sulfonate and carboxylate functionalities (1,2- and 1,3-benzenedisulfonate, 1,5-naphthalenedisulfonate, 2,6-naphthalenedisulfonate, 4-sulfobenzoate, 2,6-naphthalenedicarboxylate, and terephthalate dianions). The molecules were
