  • Patent number: 6114397
    Abstract: A method for treating cancer in a human, which comprises administering to the human subject an anti-cancer effective amount of a compound selected from gossypol, gossypol acetic acid, gossypolone, metabolites thereof, or physiologically acceptable salts thereof. Also included is a method for treating cancer in a human which comprises administering to the human subject an anti-cancer effective amount of any of the compounds listed above in combination with an anti-cancer effective amount of other conventional chemotherapeutic agents. Finally, the invention also encompasses a pharmaceutical composition comprising an anti-cancer effective amount of gossypol, gossypol acetic acid, or gossypolone, and an anti-cancer effective amount of a conventional chemotherapeutic agent, or combinations of the latter.
    Type: Grant

    Date of Patent: September 5, 2000
    Assignee: The United States of America as represented by the Department of Health and Human Services
    Inventors: Mary R. Flack, Richard Knazek, Marcus Reidenberg
  • Patent number: 5498537
    Abstract: The application concerns a method for the serum-free production of packaged and infectious vital vectors in an artificial capillary system cartridge. The invention further concerns transducing target cells with the vital vectors. The invention is particularly suitable for producing transduced target cells free of adherent serum proteins.

  • Patent number: 4220725
    Abstract: The growth of cells within a device containing a bundle of semi-permeable, tubular capillaries is disclosed. The bundle of capillaries is wrapped in an envelope of porous sheet material, thus creating an extra-envelope space into which the cells can migrate for periodic removal without disturbing the main culture within the capillaries. Porous capillaries may also be employed, in place of or in addition to the porous envelope.

  • Patent number: 4206015
    Abstract: A method for simulation of lymphatic drainage using artificial capillary cell culture device having two separate perfusion circuits, and with the ultrafiltration fibers of the two circuits being woven into a single bundle. The present device provides a matrix for high density growth of cultured cells in a continuous perfusion system. The device is particularly well adapted for the use of pressure differences between perfusion circuits.
