Definitions

  • the present invention relates to novel 4,4-(disubstituted)cyclohexan-l-ylidine acetate monomers and related compounds, pharmaceutical compositions containing these compounds, and their use in treating allergic and inflammatory diseases and for inhibiting the production of Tumor Necrosis Factor (TNF).
  • TNF Tumor Necrosis Factor
  • Bronchial asthma is a complex, multifactorial disease characterized by reversible narrowing of the airway and hyperreactivity of the respiratory tract to external stimuli.
  • Cyclic AMP has been shown to be a second messenger mediating the biologic responses to a wide range of hormones, neurotransmitters and drugs; [Krebs Endocrinology Proceedings of the 4th International Congress Excerpta Medica, 17-29, 1973].
  • adenylate cyclase is activated, which converts Mg + 2-ATP to cAMP at an accelerated rate.
  • Cyclic AMP modulates the activity of most, if not all, of the cells that contribute to the pathophysiology of extrinsic (allergic) asthma.
  • cAMP cyclic nucleotide phosphodiesterases
  • PDE isozyme
  • PDE IV is responsible for cAMP breakdown in airway smooth muscle and inflammatory cells.
  • Talphy "Phosphodiesterase Isozymes: Potential Targets for Novel Anti-asthmatic Agents” in New Drugs for Asthma, Barnes, ed. HBC Technical Services Ltd., 1989]. Research indicates that inhibition of this enzyme not only produces airway smooth muscle relaxation, but also suppresses degranulation of mast cells, basophils and neutrophils along with inhibiting the activation of monocytes and neutrophils.
  • PDE IV inhibitors are markedly potentiated when adenylate cyclase activity of target cells is elevated by appropriate hormones or autocoids, as would be the case in vivo.
  • PDE IV inhibitors would be effective in the asthmatic lung, where levels of prostaglandin E2 and prostacyclin (activators of adenylate cyclase) are elevated.
  • Such compounds would offer a unique approach toward the pharmacotherapy of bronchial asthma and possess significant therapeutic advantages over agents currently on the market.
  • TNF Tumor Necrosis Factor
  • rheumatoid arthritis rheumatoid spondylitis
  • osteoarthritis gouty arthritis and other arthritic conditions
  • sepsis septic shock, endotoxic shock, gram negative sepsis
  • toxic shock syndrome adult respiratory distress syndrome
  • cerebral malaria chronic pulmonary inflammatory disease
  • silicosis pulmonary sarcoidosis
  • bone resorption diseases reperfusion injury, graft vs.
  • allograft rejections fever and myalgias due to infection, such as influenza, cachexia secondary to infection or malignancy, cachexia secondary to human acquired immune deficiency syndrome (AIDS), AIDS, ARC (AIDS related complex), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis, or pyresis, in addition to a number of autoimmune diseases, such as multiple sclerosis, autoimmune diabetes and systemic lupus erythematosis.
  • AIDS acquired immune deficiency syndrome
  • AIDS AIDS
  • ARC AIDS related complex
  • keloid formation scar tissue formation
  • Crohn's disease Crohn's disease
  • ulcerative colitis ulcerative colitis
  • pyresis in addition to a number of autoimmune diseases, such as multiple sclerosis, autoimmune diabetes and systemic lupus erythematosis.
  • ADDS results from the infection of T lymphocytes with Human Immunodeficiency Virus (HIV).
  • HIV Human Immunodeficiency Virus
  • HIV-1 HIV-1
  • HIV-2 HIV-2
  • HIV-3 HIV-3
  • HIV entry into the T lymphocyte requires T lymphocyte activation.
  • Viruses such as HIV-1 or HIV-2 infect T lymphocytes after T cell activation and such virus protein expression and/or replication is mediated or maintained by such T cell activation. Once an activated T lymphocyte is infected with HIV, the T lymphocyte must continue to be maintained in an activated state to permit HIV gene expression and/or HIV replication.
  • Cytokines are implicated in activated T-cell-mediated HIV protein expression and/or virus replication by playing a role in maintaining T lymphocyte activation. Therefore, interference with cytokine activity such as by inhibition of cytokine production, notably TNF, in an HIV-infected individual aids in limiting the maintenance of T cell activation, thereby reducing the progression of HIV infectivity to previously uninfected cells which results in a slowing or elimination of the progression of immune dysfunction caused by HIV infection.
  • Monocytes, macrophages, and related cells such as kupffer and glial cells, have also been implicated in maintenance of the HIV infection. These cells, like T cells, are targets for viral replication and the level of viral replication is dependent upon the activation state of the cells.
  • TNF has also been implicated in various roles with other viral infections, such as the cytomegalovirus (CMV), influenza virus, adenovirus, and the herpes virus for similar reasons as those noted.
  • CMV cytomegalovirus
  • influenza virus influenza virus
  • adenovirus adenovirus
  • herpes virus herpes virus
  • TNF is also associated with yeast and fungal infections. Specifically Candida albicans has been shown to induce TNF production in vitro in human monocytes and natural killer cells.
