A small drug molecule, salicylic acid, has been converted into well-defined dendritic macromolecules. The mono-disperse nature of these materials may be clearly shown by NMR and GPC. A third generation salicylic acid dendrimer contains sixty salicylic acid residues, which make up its core, branches, and periphery. Individual salicylic acid moieties in the dendrimer are connected to one another via hydrolyzable diester linkages. (c) 2006 Elsevier Ltd. All rights reserved.

The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.
The present invention relates in general to polymer-drug conjugates. In particular, the invention relates to polymer-drug conjugates wherein the conjugated drugs are selected from prostaglandins and substituted prostaglandins, to a method of delivering such prostaglandin drugs to a subject, to a sustained drug delivery system comprising the polymer-drug conjugates, to a method of preparing the polymer-drug conjugates, and to an implant comprising the polymer-drug conjugates. The polymer-drug conjugates may be useful for delivering prostaglandins and substituted prostaglandins for the treatment of glaucoma.
