ABSTRACT:

TECHNICAL FIELD
The present invention relates to a pharmaceutical agent, particularly, a piperazine compound useful as a TNF-&agr; production inhibitor and/or an IL-10 production promoter, and use thereof as a pharmaceutical agent.
BACKGROUND ART
There are a number of cytokines that have been found as proteins involved in the expression of biological functions, such as biological immune responses, inflammatory reactions and the like. Of such cytokines, tumor necrosis factor alpha (hereinafter to be referred to as TNF-&agr;) was first found as a cytokine having an anti-tumor effect. Subsequent studies have characterized it as a cytokine involved in inflammations. In recent years, TNF-&agr; has been recognized as a cytokine broadly involved in biophylaxis through inflammation and immune responses.
For example, TNF-&agr; has been reported to show a promoting effect on the production of interleukin-1 (hereinafter to be referred to as IL-1), which is an inflammatory cytokine, and the like, an endotoxin shock induction effect, a fibroblast proliferation effect, a bone resorption effect, and an action to cause arthritis, such as cartilage destruction effect and the like [Beutler, B., et al., Nature, 316, 552-554 (1985):Peetre, C., et al., J. Clin. Invest., 78, 1694-1700 (1986):Bevilacqua, M. P., et al., Science, 241, 1160-1165 (1989)].
In rheumatoid arthritis, TNF-&agr; activity has been found in synovial fluid and sera [Macnaul, K. L., et al., J. Immunol., 145, 4154-4166 (1990):Brennan, F. M., et al., J. Immunol., 22, 1907-1912 (1992)]. Since an anti-TNF-&agr; chimera antibody has been recently reported to be effective against rheumatoid arthritis and Crohn's disease, the importance of TNF-&agr; in these diseases has been recognized [Elliott, M. J, et al., Arthritis Rheum., 36, 1681-1690 (1993):VanDullemen, H. M. et al., Gastroenterology 109, 129-135 (1995)].
Increased TNF-&agr; concentrations have been reported in the expectoration of patients with adult respiratory distress syndrome (ARDS), which is a serious respiratory disease, and TNF-&agr; is considered to be involved in ARDS [Marks, J. D. et al., Am. Rev. Respir. Dis. 141, 94-97 (1990), Millar, A. B. et al., Nature, 324, 73 (1986)]. TNF-&agr; is also considered to be involved in viral hepatitis and fulminant viral hepatitis [Sheron, N. et al., Lancet 336, 321-322 (1990), Muto, Y. et al., Lancet, ii, 72-74 (1986)].
In the case of myocardial ischemia, such as acute myocardial infarction, the TNF-&agr; concentration in blood has been reported to increase [Latini, R., et al., J. Cardiovasc. Pharmacol., 23, 1-6 (1990)], thereby suggesting the involvement of TNF-&agr; in such disease state [Squadrito, F. et al., Inflammation Res., 45, 14-19 (1996), Lefer, A. M. et al., Science, 249, 61-64 (1990)]. More recently, TNF-&agr; has been reported to inhibit myocardial contraction [Finkel, M. S., et al., Science, 257, 387-389 (1992); Pagani, D. F., et al., J. Clin. Invest., 90, 389-398 (1992)].
In addition, TNF-&agr; has been found to be equivalent to cachectin which is a cachexia inducer that hypercatabolizes the systemic metabolism in cancer and infectious diseases and causes utmost exhaustion [B. Beutler, D. Greenwald, J. D. Hulmes et al., Nature, 316, 552-554 (1985)].
TNF-&agr; is listed as one of the causes of sepsis [Starnes, H. F. Jr. et al., J. Immunol., 145, 4185-4191 (1990), Lechner, A. J. et al., Am. J. Physiol., 263, 526-535 (1992)], and an inhibitory effect on septic shock has been acknowledged in an experiment using a TNF-&agr; antibody [Starnes, H. F. Jr., et al., J. Immunol., 145, 4185-4191 (1990); Beutler, B., et al., Science, 229, 869-871 (1985)].
Other than the above-mentioned, possible involvement of TNF-&agr; has been suggested in osteoarthritis [Lewis, A. J. et al., Immunopharm. Immunotoxicol., 17, 607-613 (1995), Venn, G., et al., Arthritis Rheum., 36(6), 819-826 (1993)], multiple sclerosis [Sharief, M. K., etal., Engl. J.

Interleukin-10 (hereinafter to be referred to as IL-10) is a cytokine mainly produced by type 2 helper T cells. IL-10 potentiates activity of B cells and mast cells, but for macrophages, it is one of the inhibitory cytokines that strongly inhibit the function of type 1 helper T cell involved in cellular immunity, because they inhibit antigen presenting ability or cytokine (TNF-&agr;, IL-1 and the like) production capability of macrophages. Thus, IL-10 plays an important role in the immune response system. For example, IL-10 has been reported to inhibit TNF-&agr; production by joint synovial cells in rheumatoid arthritis
