Cyclooctanone derivatives and cyclodecanone derivative, and use thereof

TECHNICAL FIELD

[0001] The present invention relates to cyclooctane derivatives and cyclodecanone derivatives which have cytokine production inhibitory activity, and to use thereof. As used herein, cytokine refers to a proteineous factor that is released by cells and mediates intercellular communication such as the regulation of immunoresponse and inflammatory response, anti-viral and tumoral activity, the regulation of cellular proliferation and differentiation, and the like.

BACKGROUND ART

[0002] TNF-α (tumor necrosis factor), a member of cytokine family, was discovered to be a substance which has cell death inducing activity and cell proliferation inhibiting activity against tumor cells. Thereafter it has been reported that TNF-α can be produced by monocyte or macrophage stimulated by lipopolysaccharide and the like, which plays a key role in the inflammation or immunoreaction. Moreover, it has been revealed that TNF-α has a wide variety of biological activities on greatly different types of cell in addition to tumor cell, including the activation of macrophage and neutrophile, the expression of adhesive molecules in the endothelial cell, the increased proliferation of fibroblast cells, the activation of human immune deficiency virus (HIV-1) gene in CD4 positive cell and macrophage, and the like (Nature, vol. 320, 1986, pp 584-588).

[0003] IL-6, a member of cytokine family, was discovered to be a substance which promotes the differentiation of B cell into antibody producing cell without showing any effect on B cell proliferation and which is secreted in the culture supernatant of T cell stimulated with mitogen. Then, it was reported that IL-6 was produced when T cell as well as monocytes, macrophage and the like were stimuleted with cytokines such as lipopolysaccharide, TNF, IL-1 and the like. Moreover, it has been revealed that IL-6 has a wide variety of biological activities on greatly different types of cell in addition to B cell including the production of acute phase reactive protein in hepatic cell, the promotion of osteoclast bone resorption, the increase in platelet number and the like (Blood, vol. 7, 1989, pp 1-10).

[0004] IL-2, a member of cytokine family, is known as a T cell proliferation factor. IL-2 was mainly produced by T cell and to some extent by NK cell. Induced production of interferon γ in T or NK cell by IL-2 has an important rule in the formation of cytokine network.

[0005] TNF-α has been shown to be involved in the exacerbation and progression of diseased conditions including chronic rheumatoid arthritis, osteoarthritis, sepsis, Crohn's disease, diabetes mellitus, fulminant hepatitis, cachexia due to end-stage cancer and the like. IL-6 was been shown to be involved in the exacerbation and progression of diseased conditions including chronic rheumatoid arthritis, atrial myxoma, Castleman's syndrome, multiple myeloma, hyper gamma-globulinemia in present individuals with AIDS and the like. Steroids have been previously known to a substance which can inhibit TNF-α, IL-6 and IL-2. Their effects have been definitely appreciated, but there has been a problem of serious side effects following their prolonged use. Additionally, clinical applications of anti-TNF-α antibody, anti-IL-6 antibody and anti-IL-2 antibody have been investigated mainly for the treatment of chronic rheumatoid arthritis. Their effects have been appreciated, but there have been problems of the limitation that they can be used only for injection, the appearance of antibodies against anti-TNF-α antibody, anti-IL-6 antibody and anti-IL-2 antibody following continuous use leading to decreased effectiveness, expensiveness to formulate them into therapeutic drugs and the like. Therefore, it is expected that exploration of lower molecular weight compounds to inhibit the production of TNF-α, IL-6 and IL-2 results in the development of useful drugs which can be replaced for steroids and antibody formulations for the treatment of these diseases.

Test Example 1

Inhibitory Activity of Human Peripheral Blood Monocyte to Produce TNF-α and IL-6 Production

[0424] TNF-α and IL-6 production inhibitory activity of the compound of the present invention was evaluated by determining the amounts of TNF-α and IL-6 produced by the human peripheral blood monocyte stimulated with lipopolysaccharide(LPS). Briefly, human peripheral blood monocyte fraction was isolated from the peripheral venous blood from healthy male volunteers by density gradient centrifugation with Ficoll-Paque (Pharmacia). The monocytes were suspended in RPMI 1640 medium (Gibco BRL) containing 10% FCS and seeded at 5×105 cell/160 μl in a 96-well plate.

[0425] The present compound was added to the monocytes cultured and the mixture was left at 37° C. for thirty minutes. Then the monocytes were stimulated by adding LPS (Sigma) at a final concentration of 10 ng/ml and left 37° C. for eighteen hours. For control, the cells were used wherein LPS was added to the cell at a final concentration of 10 ng/ml without the present compound.

[0426] The amount of each of TNF-α and IL-6, which were released in the culture supernatant, was measured using an ELISA kit (R & D). The inhibitory rate (%) of TNF-α and IL-6 production as compared to control was calculated using the following formula from the amounts of TNF-α and IL-2 thus measured:

Inhibitory rate = \frac{(Amount produced with compound)}{(Amount produced without compound)} \times 100

[0427] In addition, the concentration of the present compound to inhibit 50% (IC50) was calculated by plotting the inhibitory rate (%) of IL-6 and TNF-α production obtained by varying a final concentration of the present compound of from 0.1 μM to 100 μM. Results are shown in Table 2.

[0428] As can be seen from Table 2, the present compound inhibited TNF-α and IL-2 production.

Test Example 2

Inhibitory Activity of Human Peripheral Lymphocyte to Produce IL-2 Production

[0429] Human peripheral lymphocytes were stimulated with mitogen (PHA) to induce IL-2 production. The amount of IL-2 produced was measured to evaluate the inhibitory effect of the present compound. Briefly, human peripheral blood monocyte fraction was isolated in a manner similar to Test Example 1.

[0430] The monocytes were suspended in RPM 1640 medium (Gibco BRL) containing 10% FCS and seeded in a petri dish and left at 37° C. for an hour. Then, the cells (lymphocytes) which were not attached to the wall of the petri desh were isolated by centrifligation. The lymphocytes collected were suspended in the medium and seeded at 5×105 cell/160 μl in a 96-well plate.

[0431] The present compound was added to the lymphocytes cultured and the mixture was left at 37° C. for thirty minutes. Then, the cells were stimulated by adding PHA (Difco) at a final concentration of 10 μl/ml and left at 37 ° C. for forty eight hours. For control, the cells were used wherein PHA was added to the cell at a final concentration of 10 1μl/ml without the present compound.

[0432] The amount of IL-2 which was released in the culture supernatant was measured using an ELISA kit (BioSource International). The inhibitory rate (%) of IL-2 production as compared to control was calculated using the following formula from IL-2 amounts thus measured:

Inhibitory rate = \frac{(Amount produced with compound)}{(Amount produced without compound)} \times 100

[0433] In addition, the concentration of the present compound to inhibit 50% (IC50) was calculated by plotting the inhibitory rate (%) of IL-2 production obtained by varying a final concentration of the present compound of from 0.1 μM to 100 μM. Results are shown in Table 3.
