Abstract
Provided are aromatic compounds, phospholipid-polymer-aromatic conjugates comprising the aromatic compounds, and liposome compositions including the phospholipid-polymer-aromatic conjugates. The liposomal compositions may be useful for imaging of Alzheimer's Disease, for example, imaging of the amyloid-β plaque deposits characteristic of Alzheimer's Disease.

A liposomal composition, comprising:
- a membrane, comprising:
- a phospholipid-polymer-aromatic conjugate, the aromatic moiety in the phospholipid-polymer-aromatic conjugate comprising:
A kit for imaging amyloid deposits in a patient, the kit comprising:
- a liposomal composition, the liposomal composition comprising:
- a membrane, comprising:
- a phospholipid-polymer-aromatic conjugate, the aromatic moiety in the phospholipid-polymer-aromatic conjugate comprising:
- a nonradioactive magnetic resonance imaging (MM) contrast enhancing agent at least one of encapsulated by or bound to the membrane;
- and
- instructions, the instructions directing a user to:
- introduce into the patient a detectable quantity of the liposomal composition;
- allow sufficient time for the liposomal composition to be associated with one or more amyloid deposits;
- and
- detect the liposomal composition associated with the one or more amyloid deposits.
