Description: 3 -(Disubstituted)cvclohexan-l-carboxylate Dimers and Related Compounds Field of Invention The present invention relates to novel dimers of 3,3-(disubstituted)cyclohexan- 1-carboxylate dimers 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). Background of the Invention Bronchial asthma is a complex, multifactorial disease characterized by reversible narrowing of the airway and hyperreactivity of the respiratory tract to external stimuli. Identification of novel therapeutic agents for asthma is made difficult by the fact that multiple mediators are responsible for the development of the disease. Thus, it seems unlikely that eliminating the effects of a single mediator will have a substantial effect on all three components of chronic asthma. An alternative to the "mediator approach" is to regulate the activity of the cells responsible for the pathophysiology of the disease. One such way is by elevating levels of cAMP (adenosine cyclic 3',5'- moπophosphate). 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]. When the appropriate agonist binds to specific cell surface receptors, 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. As such, an elevation of cAMP would produce beneficial effects including: 1) airway smooth muscle relaxation, 2) inhibition of mast cell mediator release, 3) suppression of neutrophil degranulation, 4) inhibition of basophil degranulation, and 5) inhibition of monocyte and macrophage activation. Hence, compounds that activate adenylate cyclase or inhibit phosphodiesterase should be effective in suppressing the inappropriate activation of airway smooth muscle and a wide variety of inflammatory cells. The principal cellular mechanism for the inactivation of cAMP is hydrolysis of the 3'- phosphodiester bond by one or more of a family of isozymes referred to as cyclic nucleotide phosphodiesterases (PDEs). It has now been shown that a distinct cyclic nucleotide phosphodiesterase (PDE) isozyme, PDE IV, is responsible for cAMP breakdown in airway smooth muscle and inflammatory cells. [Torphy, "Phosphodiesterase Isozymes: Potential Targets for Novel Anti-asthmatic Agents" in New Drugs for Asthma, Barnes, ed. IBC 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. Moreover, the beneficial effects of PDE IN 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. Thus PDE IN 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. The compounds of this invention also inhibit the production of Tumor Necrosis Factor (TNF), a serum glycoprotein. Excessive or unregulated TNF production has been implicated in mediating or exacerbating a number of diseases including 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. host reaction, 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 results from the infection of T lymphocytes with Human Immunodeficiency Virus (HTV). At least three types or strains of HTV have been identified, i.e., HTV-1, HTV-2 and HTV-3. As a consequence of HTV infection, T-cell- mediated immunity is impaired and infected individuals manifest severe opportunistic infections and/or unusual neoplasms. HTV entry into the T lymphocyte requires T lymphocyte activation. Viruses such as HTV-1 or HTV-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 HTV, the T lymphocyte must continue to be maintained in an activated state to permit HTV gene expression and/or HTV replication. Cytokines, specifically TNF, are implicated in activated T-cell-mediated HTV protein expression and/or virus replication by playing a role in maintaining T -Jvmphocyte activation. Therefore, interference with cytokine activity such as by inh ition of cytokine production, notably TNF, in an HTV-infected individual aids in limiting the maintenance of T cell activation, thereby reducing the progression of HTV infectivity to previously uninfected cells which results in a slowing or elimination of the progression of immune dysfunction caused by HIN infection. Monocytes, macrophages, and related cells, such as kupffer and glial cells, have also been implicated in maintenance of the HTV 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. [Sec Rosenberg et al., The Immunopathogenesis of HTV Infection, Advances in Immunology, Vol. 57, 1989]. Monolάnes, such as TΝF, have been shown to activate HTV replication in monocytes and/or macrophages [See Poli et al., Proc. Νatl. Acad. Sci., 87:782-784, 1990], therefore, inhibition of monokine production or activity aids in limiting HTV progression as stated above for T cells. TΝF 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. TΝF is also associated with yeast and fungal infections. Specifically Candida albicans has been shown to induce TΝF 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. See also Wasan et al, Antimicrobial Agents and Chemotherapy, 35,(10):204ό-48, 1991; and Luke et al, Journal of Infectious Diseases, 162:211-214,1990]. The ability to control the adverse effects of TΝF is furthered by the use of the compounds which inhibit TΝF in mammals who are in need of such use. There remains a need for compounds which are useful in treating TΝF-mediated disease states which are exacerbated or caused by the excessive and/or unregulated production of TΝF.

The term "C .3 alkyl", "C1.4 alkyl", "C^ alkyl" or "alkyl" groups as used herein is meant to include botii straight or branched chain radicals of 1 to 10, unless die chain length is limited diereto, including, but not limited to methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tcrt-butyl, and the like. "Alkenyl" means both straight or branched chain radicals of 1 to 6 carbon lengths, unless the chain length is limited diereto, including but not limited to vinyl, 1 - propenyl, 2-propenyl, 2-propynyl, or 3-methyl-2-propenyl. The term "cycloalkyl" or "cycloalkyl alkyl" means groups of 3-7 carbon atoms, such as cyclopropyl, cyclopropylmethyl, cyclopentyl, or cyclohexyl. "Aryl" or "aralkyl", unless specified otherwise, means an aromatic ring or ring system of 6-10 carbon atoms, such as phenyl, benzyl, phenethyl, or naphtiiyl. Preferably the aryl is monocyclic, i.e, phenyl. The alkyl chain is meant to include both straight or branched chain radicals of 1 to 4 carbon atoms. "Heteroaryl" means an aromatic ring system containing one or more heteroatoms, such as imidazolyl, triazolyl, oxazolyl, pyridyl, pyrimidyl, pyrazolyl, pyrrolyl, furanyl, or diienyl. "Halo" means all halogens, i.e., chloro, fluoro, bromo, or iodo. "Inhibiting die production of EL-1 " or "inhibiting the production of TNF' means: a) a decrease of excessive in vivo IL-1 or TNF levels, respectively, in a human to normal levels or below normal levels by inhibition of the in vivo release of IL-1 by all cells, including but not limited to monocytes or macrophages; b) a down regulation, at the translational or transcriptional level, of excessive in vivo IL-1 or TNF levels, respectively, in a human to normal levels or below normal levels; or c) a down regulation, by inhibition of the direct synthesis of IL- 1 or TNF levels as a postranslational event The phrase "TNF mediated disease or disease states" means any and all disease states in which TNF plays a role, either by production of TNF itself, or by TNF causing another cytokine to be released, such as but not limited to IL-1 or IL-6. A disease state in which EL-1, for instance is a major component, and whose production or action, is exacerbated or secreted in response to TNF, would dierefore be considered a disease state mediated by TNF. As TNF-β (also known as lymphotoxin) has close structural homology with TNF-α (also known as cachectin), and since each induces similar biologic responses and binds to die same cellular receptor, both TNF-α and TNF-β are inhibited by the compounds of the present invention and tiius are herein referred to collectively as "TNF" unless specifically delineated odierwise. Preferably TNF-α is inhibited. "Cytokine" means any secreted polypeptide that affects the functions of cells, and is a molecule which modulates interactions between cells in immune, inflammatory, or hematopoietic responses.
