    摘要: Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl Lex, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.

    摘要: Peptide vectors having high KDR binding affinity and processes for making such vectors are provided. The peptide vectors may be conjugated to phospholipids and included in ultrasound contrast agent compositions. Such ultrasound contrast agents are particularly useful in therapeutic and diagnostic methods, such as in imaging KDR-containing tissue and in the evaluation and treatment of angiogenic processes associated with neoplastic conditions. The present invention also provides processes for the large scale production of highly pure dimeric and monomeric peptide phospholipid conjugates as well as precursor materials used to form the conjugates. The present invention further provides processes for the large scale production of highly pure peptide phospholipid conjugates which contain very low levels of TFA.
