  • Patent number: 6096787
    Abstract: In accordance with the present invention, there is provided a method for the treatment of subjects afflicted with steroid or steroid-like hormone-responsive disease states. The invention method comprises administering to the subject an effective amount of a ligand which selectively interacts with the receptor subtype associated with the steroid or steroid-like hormone-responsive disease state, wherein said ligand interacts with said receptor subtype to a significantly greater extent than with other subtypes of the same receptor class.

  • Patent number: 6043279
    Abstract: Compounds, compositions, and methods for modulating processes mediated by Retinoid X Receptors using retinoid-like compounds which have activity selective for members of the subclass of Retinoid X Receptors (RXRs), in preference to members of the subclass of Retinoic Acid Receptors (RARs). Examples of such compounds are bicyclic benzyl, pyridinyl, thiophene, furanyl, and pyrrole derivatives. The disclosed methods employ compounds for modulating processes selectively mediated by Retinoid X Receptors.

  • Patent number: 6028052
    Abstract: This invention relates to methods and compositions for the treatment of non-insulin-dependent diabetes mellitus using an RXR agonist alone or in combination with a PPAR.gamma. agonist such as a thiazolidinedione compound.
    Type: Grant
    Filed: September 17, 1996
    Date of Patent: February 22, 2000
    Assignee: Ligand Pharmaceuticals Incorporated
    Inventors: Richard A. Heyman, Rosemary Cesario, Ranjan Mukherjee
  • Patent number: 5990163
    Abstract: In accordance with the present invention, ligands have been discovered which selectively bind retinoid X receptors. Such ligands can be used for the selective modulation of retinoid X receptor mediated processes. In a further aspect of the present invention, there are provided pharmaceutical compositions comprising a pharmaceutically acceptable vehicle containing at least one of the above-described selective ligands. Such compositions are useful, for example, for the treatment of a variety of retinoid X receptor mediated disease states.

  • Patent number: 5972881
    Abstract: This invention relates to methods and compositions for the treatment of non-insulin-dependent diabetes mellitus using an RXR agonist alone or in combination with a PPAR.gamma. agonist such as a thiazolidinedione compound.
    Type: Grant
    Filed: November 26, 1997
    Date of Patent: October 26, 1999
    Assignee: Ligand Pharmaceuticals Incorporated
    Inventors: Richard A. Heyman, Rosemary Cesario, Ranjan Mukherjee
  • Patent number: 5968989
    Abstract: In accordance with the present invention, there are provided methods to modulate processes mediated by retinoid receptors, employing high affinity, high specificity ligands for such receptors. In one aspect of the present invention, there are provided ligands which are more selective for the retinoid X receptor than is retinoic acid (i.e., rexoids). In another aspect of the present invention, alternative ligands (other than retinoic acid) have been discovered which are capable of inducing retinoic acid receptor mediated processes. In yet another aspect, methods have been developed for the preparation of such retinoid receptor ligands from readily available compounds.

  • Patent number: 5932622
    Abstract: A method for modulating non-malignant skin related disorders in a subject has been demonstrated with 9-cis retinoic acid. Wrinkling, acne, keratinization, differentiation and proliferation disorders are treated by administration of 9-cis retinoic acid alone or in a pharmaceutically acceptable carrier to a subject in need thereof.
