  • Selectively functionalizable desdendrimers
    Patent number: 5994495
    Abstract: A new class of branched dendrimeric macromolecules, is described essentially consisting of a polyvalent central nucleus and a series of polyoxaalkylene "dendra". Such molecules are characterized by the presence of at least one branch, attached either directly to the "core" or to a "dendron", which does not participate in the growth and which therefore differs from all the other functions of the macromolecule.
    Type: Grant
    Filed: May 11, 1998
    Date of Patent: November 30, 1999
    Assignee: Dibra S.p.A.
    Inventors: Luigia Gozzini, Monica Muttoni
  • Binary-branched polyoxaalkylene macromolecules process for making them and their uses
    Patent number: 5886110
    Abstract: Branched, dendrimeric macromolecules having a central nucleus and a series of polyoxaalkylene chains that radiate from the nucleus and spread into the surrounding space branching a cascade fashion until the desired size results. Molecules formed in this manner are free of excessive functional crowding on their outer surfaces. Synthetic methods of preparing these molecules and their uses are described.
    Type: Grant
    Filed: April 30, 1998
    Date of Patent: March 23, 1999
    Assignee: Dibra S.p.A.
    Inventors: Luigia Gozzini, Monica Muttoni, Christoph De Haen

    Inventors: Luigia Gozzini, Monica Muttoni
  • Branced polyoxaalkyl macromolecules
    Patent number: 5780644
    Abstract: Branched, dendrimeric-type macromolecules composed essentially of a central nucleus and of a series of polyoxaalkyl chains that depart from said nucleus and spread into the surrounding space branching in a cascade fashion useful as carriers of drugs, contrast agents, etc.
    Type: Grant
    Filed: March 15, 1995
    Date of Patent: July 14, 1998
    Assignee: Dibra S.p.A.
    Inventors: Luigia Gozzini, Monica Muttoni, Christoph DeHaen
  • Use of dendrimeric-type macromolecules as catalysts or coadjuvants in phase transfer catalysis reactions
    Patent number: 5705667
    Abstract: The present invention concerns the use of dendrimeric-type branched macromolecules, comprising polyoxaalkylene chains, as catalysts or coadjuvants of phase transfer catalysis reactions.
