In each derivative, termed an "amplifier" because the dendritic structure on each molecule terminates with multiple termini to each of which an "active group" can be attached, the desired effect of the active group per mole is amplified compared to conventional compounds having only one active group per molecule. Amplifier molecules can include a targeting group permitting the molecules to preferentially attach to a particular anatomical or physiological situs. Active groups are any of various pharmacologically or therapeutically active moieties, including moieties useful for magnetic-resonance contrast enhancement. The dendritic structures comprise linkers and branch groups covalently bonded to each other in any of various structural combinations. The amplifiers can be prepared as a solution or mixture with a physiologically compatible carrier for administration to a warm-blooded animal subject.

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.

  • Patent number: 5135737
    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.
