ABSTRACT:
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. Via such chemistry, the amplifiers are attachable to monoclonal antibodies for concentration of pharmacologically active groups at a desired site in the body.
