    摘要: A liposome composition comprised of liposomes having a peptide boronic acid proteasome inhibitor compound entrapped in the liposomes is described. The boronic acid compound is entrapped in the liposomes in the form of a boronate ester, subsequent to interaction with a liposome-entrapped polyol. In one embodiment, the liposomes have an outer coating of hydrophilic polymer chains and are used to treat a malignancy in a subject.

    摘要: Liposomes containing PEG-substituted neutral lipopolymers provide similar circulation times to liposomes incorporating conventional, negatively charged PEG-substituted phospholipids. Use of the uncharged lipopolymers can also present advantages in terms of interactions with cell surfaces and reduced leakage of charged substances, particularly cationic drugs, from the liposomes. The lipopolymers are of the formula: wherein each of R1 and R2 is an alkyl or alkenyl chain having between about 8 to about 24 carbon atoms, n is about 10 to about 300, Z is selected from the group consisting of hydroxy, alkoxy, benzyloxy, carboxylic ester, sulfonic ester, alkyl or aryl carbonate, amino, and alkylamino, and the linkage L is selected from the group consisting of (i) —X—(C═O)—Y—CH2—, (ii) —X—(C═O)—, and (iii) —X—CH2—, wherein X and Y are independently selected from oxygen, NH, and a direct linkage.

    摘要: A composition of polymer-coated particles, and a polymer compound used in forming the particles are disclosed. The polymer compound is composed of a hydrophilic polymer attached to a lipophilic moiety through a linking segment which contains chemical groups through which the compound can be crosslinked to other such compounds. The particles in the composition are prepared by forming lipid structures containing ordered arrays of the polymer compounds, and crosslinking the compounds through their chemical groups. The particles are used for parenteral administration of a pharmaceutical compound which is entrapped in the particles.

    摘要: Polymer-biomolecule conjugates are prepared, generally in a site-specific or -selective manner, by a four-component condensation reaction. The method may be used to prepare conjugates having two polymer molecules attached at a single site on a biomolecule. The conjugates are typically water soluble and have beneficial pharmacological properties, such as reduced immunogenicity and increased circulation time.
