摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

摘要:Compositions and methods for dual imaging and for dual chemotherapy and radiotherapy are disclosed. More particularly, the invention concerns compounds comprising the structure X 1 —Y—X 2 , wherein Y comprises two or more carbohydrate residues covalently attached to one another, X 1 and X 2 are diagnostic or therapeutic moieties covalently attached to Y, provided that when Y does not comprise a glucosamine residue, X 1 and X 2 are diagnostic moieties. The present invention also concerns methods of synthesis of these compounds, application of such compounds for dual imaging and treatment of hyperproliferative disease, and kits for preparing a radiolabeled therapeutic or diagnostic compound.
