A liposome composition comprised of liposomes having a peptide boronic acid proteasome inhibitor compound entrapped in the liposomes is described. More specifically, liposomes having a compound of Formula I or II entrapped in the interior aqueous compartment are loaded with a peptide boronic acid compound, to form a boronate ester compound inside the liposomal aqueous compartment. In one embodiment, the liposomes have an outer coating of hydrophilic polymer chains and are used to treat a solid tumor in a subject. |
