  • European Patent Application 306 846 discloses sulphonamides of formula:-
  • R 3 may be sulphonamide, as catechol-O-methyl transferase inhibitors.
  • Phosphodiesterases regulate cyclic AMP concentrations.
  • Phosphodiesterase IV has been demonstrated to be a principal regulator of cyclic AMP in respiratory smooth muscle and inflammatory cells. [See Torphy and Creslinski, Molecular Pharmacology 37, 206, (1990) ; Dent et al British Journal of Pharmacology, 90 I63p (1990)].
  • Inhibitors of phosphodiesterase IV have been implicated as being bronchodilators and asthma-prophylactic agents and as agents for inhibiting eosinophil accumulation and the function of eosinophils.
  • Inhibitors of phosphodiesterase IV are also implicated in treating inflammatory diseases, proliferative skin disease and conditions associated with cerebral metabolic inhibition.

  • 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. [See Riipi et al., Infection and Immunity, 58(9) :2750-54, (1990); and Jafari et al., Journal of Infectious Diseases, 164:389-95, (1991) .
