  • Publication number: 20100202967
    Abstract: The present invention relates to a novel class of diagnostically or therapeutically effective compounds comprising novel peptides able to bind fibrin, to a process for their preparation and to compositions thereof for use in therapy and diagnostics. The compounds of the invention bind, in particular, to fibrin present in the extracellular matrix (EC) of tumor or connective tissue of stroma thus acting as targeting moieties able to bring and successfully bound an active moiety linked thereto to fibrin depositions inside solid tumors.

  • Publication number: 20090062509
    Abstract: A method is disclosed for the syntheses of thiol-containing radiopharmaceuticals without the need for purification starting from chelators containing disulfide bonds. This is done by providing a method that reduces disulfide bonds on a precursor molecule or a precursor compound in the presence of phosphine compounds, thus freeing thiols for metal complexation.

  • Publication number: 20080300220
    Abstract: 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.
