The present invention relates to a novel amide derivative showing a selective MMP-9 production suppressive action and pharmaceutical use thereof.
Matrix metalloprotease (MMPs) is an enzyme group playing a key role in the binding tissue degradation in living organisms. The activity of MMPs is controlled by each step of 1) production of latent enzyme (proMMP) by gene expression, 2) activation of proMMP, 3) activity inhibition by TIMP which is an inhibitor of active enzymes. MMPs includes two types of hemostatic type and induction type, the former includes MMP-2 and MMP-14, and the latter includes many MMPs such as MMP-1, 3, 9, 13 etc. Particularly, promoted production or expression in rheumatoid arthritis, osteoarthritis, multiple sclerosis, systemic lupus erythematosus and inflammatory bowel diseases (ulcerative colitis, Crohn's disease) by MMP-9 has been acknowledged, and the involvement of MMP-9 in these pathologies has been suggested [Ann. Rheum. Dis., vol. 58, page 691-697 (1999) (non-patent document 1), J. Clin. Invest., vol. 92, page 179-185 (1993) (non-patent document 2), Arthritis Rheum., vol. 46, page 2625-2631 (2002) (non-patent document 3), Lancet Neurol., vol. 2, page 747-756 (2003) (non-patent document 4), Arthritis Rheum., vol. 50, page 858-865 (2004) (non-patent document 5), Journal of Leukocyte Biology, vol. 79, page 954-962 (2006) (non-patent document 9)].
In addition, it has been suggest from the studies of MMP knockout mouse that MMP-9 is involved in the formation and progression of cancer, MMP-9 plays an important role in the progression of arthritis and articular destruction [J. Natl. Cancer Inst., vol. 94, 1134-1142 (2002) (non-patent document 6), J. Immunol., vol. 169, 2643-2647 (2002) (non-patent document 7)]. On the other hand, MMP-2 shows an anti-inflammatory action and the action mechanism thereof is considered to be degradation of MCP-3 and the like [Science, vol. 289, page 1202-1206 (2000) (non-patent document 8)]. Therefore, a medicament that does not influence MMP-2 production and selectively suppresses MMP-9 production can be expected as a novel therapeutic drug.
JP-A-2004-359657 (patent document 1) discloses leptomycin B, which is a medicament that inhibits MMP-9 production, and a derivative thereof.
The problem of the present invention is to provide a novel low-molecular-weight compound that suppresses production of induction type MMPs, particularly MMP-9, rather than production of hemostatic type MMP-2.

THP-1 cell (human monocytic leukemia cell line) was adjusted to 1×107 cells/mL in a culture medium (10% fetal bovine serum/RPMI1640 medium), and dispensed to a 96 well multiplate. This was equilibrated under the conditions of 37° C./5% CO2, and a culture medium containing human TNFα (final concentration 10 ng/mL) and a test compound was added thereto. After incubation under the conditions of 37° C./5% CO2 for 24 hr, the culture medium was centrifuged and the culture supernatant was collected, which was subjected to the following measurement.
Quantification of proMMP-9 in Culture Supernatant
The proMMP-9 concentration of the collected culture supernatant was quantified using a commercially available measurement reagent (manufactured by GE Healthcare, MMP-9, Human, Biotrak ELISA System).
Calculation of proMMP-9 Suppression Rate
The proMMP-9 suppression rate of the test compound was calculated from the following formula:
% suppression=100−((Test−Min)/(Max−Min)×100)
wherein Max is proMMP-9 concentration of culture supernatant induced by stimulation with human TNFα, without addition of a test compound (added with solvent alone)
Min is proMMP-9 concentration of culture supernatant without addition of a test compound (added with solvent alone) and without stimulation with human TNFα, and
Test is proMMP-9 concentration of culture supernatant induced by stimulation with human TNFα when a test compound is added.
Furthermore, the concentration of the test compound necessary for suppressing proMMP-9 production by human TNFα stimulated THP-1 cell by 50% (ICH value) was calculated from 3 points of proMMP-9 suppression rate at test compound concentrations of 10, 100 and 1,000 nmol/L.

wherein Cont is proMMP-2 concentration of culture supernatant without addition of a test compound (added with solvent alone) and Test is proMMP-2 concentration of culture supernatant with addition of a test compound.
The results of the Example compounds of the present invention in Experimental Examples 1 and 2 are shown in the following Table 1 and Table 2.
MMP-9 is produced as a precursor proMMP-9 by the stimulated cells, extracellularly activated and expresses the physiological activity as MMP-9. That is, evaluation of the suppression of proMMP-9 produced by the cell means evaluation of the suppression of production of MMP-9. The same applies to MMP-2, and evaluation of the suppression of proMMP-2 produced by the cell means evaluation of the suppression of production is of MMP-2.
Anesthetized rats (LEW, male, 6-week-old) were immunized with M. Butyricum (5 mg/mL) at a dose of 0.1 mL/body by subcutaneous administration from the tail root. On day 15, the hindpaw volume was measured (rat hindpaw edema volume measuring apparatus, Plethysmometer, manufactured by: Unicom (Yachiyo. Chiba, Japan) standard: TK-101 Series No.:101 GH1), and the rats were allocated such that each test group had a uniform hindpaw volume. The test compound was orally administered once a day from immediately after allocation on day 15 to day 20 at doses of 3 and 30 mg/kg, and the hindpaw volume was measured again on day 21. The amount of hindpaw edema was the difference in the amount between hindpaw volume on day 15 and that on day 21.
The results of the Example compound of the present invention in Experimental Example 3 are shown in Table 3 below.
Monoiodoacetic acid solution (0.3 mg/25 μL) was injected into the right hindpaw knee joint cavity of anesthetized rats (LEW, male, 7-week-old). A test compound was orally administered once a day from immediately after monoiodoacetic acid injection to day 6 at a dose of 10 mg/kg. On day 7, right hindpaw knee joint was taken from euthanized rats, and fixed with 10% neutral formalin solution. A pathology specimen of knee joint was prepared, stained with Hematoxylin Eosin and Safranine O, and the state of joint cartilage injury was scored under microscopic observation. For articular joint injury scores, changes in each pathological finding in medial condyle of femur and medial condyle of tibia (cartilage surface tuberosity, erosion/ulcer/fibrillation, chondrocyte disorganization/disappearance/hypertrophy, reduction of Safranine staining) were divided into mild, moderate and severe according to the method of Kobayashi et al. (Kobayashi K et al. J. Vet. Med. Sci. 65, 1195 1199 2003), and indicated in the scores of 1, 2 and 3 and totaled. Furthermore, an average of the score of medial condyle of femur and that of medial condyle of tibia was determined and used as an articular joint injury score.
The results of the Example compounds of the present invention in Experimental Example 4 are shown in Table 4 below.
A dinitrobenzene solution (30 mg/0.1 mL) was injected into the large intestine of anesthetized rats (Wistar, male, 6-week-old). A test compound was orally administered once a day from the previous day of the dinitrobenzene injection to day 7 at a dose of 30 mg/kg. On day 8, the large intestine was isolated from euthanized rats, and the wet weight thereof was measured. The large intestine weight was amended to the weight per 100 g body weight of the rats on day 8.
The results of the Example compound of the present invention in Experimental Example 5 are shown in Table 5 below.
As is clear from the results of Tables 1 and 2, the compound of the present invention has a selective MMP-9 production suppressive action, and is a highly safe compound showing suppressed expression of side effects caused by the suppression of MMP-2 production. Furthermore, since the compound of the present invention has a suppressive action on the hindpaw edema of an adjuvant-induced arthritis model (Table 3), autoimmune diseases such as rheumatoid arthritis and the like, a suppressive action on the increase of large intestine weight of a dinitrobenzene-induced colitis model (Table 5), and a suppressive action on inflammatory bowel disease (ulcerative colitis, Crohn's disease) and articular joint injury of monoiodoacetic acid-induced osteoarthritis models (Table 4), it is useful as a prophylactic and/or therapeutic drug for osteoarthritis.
