Patents by Inventor Daniel J. Coughlin

Daniel J. Coughlin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5156840
    Abstract: The invention relates to amine-containing porphyrin derivatives. Theporphyrins can be used as photosensitizers which are useful as therapeutic agents. Also described are methods for preparing conjugates in which a porphyrin derivative is covalently attached to an antibody or antibody fragment. In vivo therapeutic methods utilizing the conjugates are also desired.
    Type: Grant
    Filed: March 20, 1989
    Date of Patent: October 20, 1992
    Assignee: Cytogen Corporation
    Inventors: John W. F. Goers, Hurley D. King, Chyi Lee, Daniel J. Coughlin, Vernon L. Alvarez, John D. Rodwell, Thomas J. McKearn
  • Patent number: 5140104
    Abstract: Novel therapeutic antibody conjugates comprising amine derivatives of folic acid analogs covalently attached via a reactive amine group to an oxidized carbohydrate moiety of an antibody or antibody fragment are disclosed. The conjugates retain substantially the same immunorespecificity and immunoreactivity of the unconjugated antibody molecule. The immunospecificity and immunoreactivity of the antibody conjugates permits targeted delivery of the attached therapeutically effective amine derivative of folic acid analogs in vivo. The conjugates are therapeutically effective against a variety of neoplastic and non-neoplastic cellular disorders when administered in vivo. Methods for synthesizing the amine derivatives of folic acid analogs, methods for preparing the antibody conjugates, and methods for use of the conjugates in vivo are also disclosed.
    Type: Grant
    Filed: October 24, 1989
    Date of Patent: August 18, 1992
    Assignee: Cytogen Corporation
    Inventors: Daniel J. Coughlin, John D. Rodwell
  • Patent number: 4966999
    Abstract: Radiohalogenated compounds which are useful as intermediates for preparing radiohalogenated antibody conjugates in which the radiohalogenated compound is site specifically attached to an oxidized carbohydrate moiety of an antibody or antibody fragment are disclosed. Methods for making the compounds and the antibody conjugates as well as methods of use of the same are also disclosed In particular, phenolic hydrazide and phenolic amine compounds are disclosed.
    Type: Grant
    Filed: June 7, 1988
    Date of Patent: October 30, 1990
    Assignee: Cytogen Corporation
    Inventors: Daniel J. Coughlin, Benjamin A. Belinka, Vernon L. Alvarez
  • Patent number: 4950738
    Abstract: Novel antineoplastic amine-containing derivatives and methods for synthesizing such derivatives of anthracycline antibiotics are disclosed. The derivatives are useful to prepare site-selectively attached therapeutic antibody-anthracyline antibiotic conjugates which retain substantial immunospecificity of the unconjugated antibody molecule. Using the conjugates, targeted delivery of the attached antineoplastic amine derivatives of anthracycline antibiotics is achieved in vivo. Such conjugates are thus therapeutically effective against a variety of neoplastic cellular disorders when administered in vivo. Methods for preparing the antibody conjugates and for use of the conjugates in vivo are also disclosed.
    Type: Grant

  • Patent number: 4867973
    Abstract: This invention relates to antibody-therapeutic agent conjugates having a therapeutic agent covalently attached to an antibody or antibody fragment. Also described are methods for intermediates in the preparation of antibody conjugates. Therapeutic in vivo methods utilizing such antibody-therapeutic agent conjugates are described.
