    摘要: Fibrin-binding peptides having high binding affinity and excellent physical characteristics compared to previously known fibrin-binding peptides are provided. These fibrin-binding peptides may be conjugated to a detectable label or a therapeutic agent and used to detect and facilitate treatment of pathological conditions associated with the presence of fibrin such as thrombic, angiogenic and neoplastic conditions. These peptides may be used in imaging processes such as MRI, ultrasound and nuclear medicine imaging (e.g. PET, scintigraphic imaging, etc.). The peptides may also be used therapeutically. The present invention also provides processes and methods for making and using such peptides and conjugates thereof.

    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.
