    • The present invention provides compositions adapted to enhance reverse cholesterol transport in mammals. The compositions are suitable for oral ,delivery and useful in the treatment and/or prevention of disease conditions associated with hypercholesterolemia. For example, the compositions contain one of the following active agents: i) a compound comprising between 3 and 10 L or D amino acid residues or anal thereof, said compound having an amino and a carboxy terminal, and comprising the sequence: Xl-X2-X3, wherein X1 is an acidic amino acid, X2 a lipophilic or aromatic amino acid, and X3 is a basic amino acid, and wherein X1, X2 and X3 may be arranged in any sequential order; wherein at least one of X1, X2 or X3 further comprises a peptidomimetic modification and wherein at least one of the amino or carboxy terminals further compri a protecting group; or ii)A substantially pure amino acid-derived compound having an amino and a carboxy terminal and comprising an L or D enantiomer of an acidic amino a residue or peptidomimetic modification thereof, an L or D enantiomer of a lipophilic or aromatic amino acid residue or peptidomimetic modification thereof, and an L or D enantiomer of a basic amino acid residue or peptid mimetic modification thereof; wherein the amino and the carboxy terminal comprise a first and a second protecting group; and wherein said compound has at least one of the following properties: (1) it mimicks ApoA-I bindi to LDL and HDL, (2) it binds preferentially to liver, (3) it enhances LDL uptake by liver LDL-receptors, (4) it lower the levels of LDL, IDL, and V cholesterol, (5) it enhances cholesterol efflux from macrophages and ther inhibits foam cell formation, (6) it reduces plaque formation, (7) it increases the levels of HDL cholesterol, and (8) it improves plasma lipo­protein profiles.
