Patent number: 5135737Abstract: Disclosed are amplifier molecules: various organic compounds having branched structures terminating with amine groups to which pharmacologically active groups can be chemically attached. A number of MRI contrast-enhancing agents were synthesized, each comprising plural active groups, such as stable nitroxides and complexes of trivalent metal cations. Such syntheses were successfully performed using a number of amplifiers having different branched structures, demonstrating the general utility of the pertinent chemistry in the synthesis of amplifiers having any of a wide variety of pharmacologically active groups. Amplifiers were also synthesized having linkers terminating with chemically reactive groups such as isothiocyanates, which render the amplifier bifunctional: attachable to polymers, biomacromolecules, or other biocompatible entity possessing multiple reactive sites such as terminal amines.Type: GrantFiled: September 5, 1989Date of Patent: August 4, 1992Assignee: The State of Oregon Acting by and through the State Board of Higher Education on behalf of the University of OregonInventor: John F.
