The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.
专利号:US-8147805-B2 优先权日:2005-01-05 标题:Conjugates for dual imaging and radiochemotherapy: composition, manufacturing, and applications 发明人:YANG DAVID; YU DONGFANG; CHANDA MITHU; AZHDARINIA ALI; OH CHANGSOK; KIM E EDMUND 权利人:YANG DAVID; YU DONGFANG; CHANDA MITHU; AZHDARINIA ALI; OH CHANGSOK; KIM E EDMUND; UNIV T EXAS SYSTEM BOARD OF REGENTS 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.
