Description

This application is a 371 of PCT/JP99/05826 filed on Oct. 22, 1999.

TECHNICAL FIELD

The present invention relates to vitamin D 3 derivatives useful as pharmaceutical products or pharmaceutically permissible solvates thereof, treating agents using same and pharmaceutical compositions containing same. More particularly, the invention relates to 1α-hydroxyvitamin D 3 derivatives having neutrophilic infiltration-suppressing activity and antagonistic effect to vitamin D 3 or pharmaceutically permissible solvates thereof, treating agents for inflammatory respiratory diseases and diseases attributable to the overactivity of vitamin D 3 containing same as active ingredients and pharmaceutical compositions containing same.

BACKGROUND ART

An active vitamin D 3 derivative has calcium absorption-stimulating activity in the small intestine, and activities such as the control of bone resorption and osteogenesis in the bones, and it is used as a treating agent for diseases caused by various kinds of calcium metabolism disorders. In recent years, immunoregulatory activity, cell proliferation inhibitory activity and cell differentiation inducting activity have been found besides these activities. For example, applications to a treating agent for malignant tumor (JP-A 57-149224 (hereinafter, JP-A means Japanese unexamined patent publication)), a treating agent for rheumatoid arthritis (JP-A 56-26820), an antiallergic agent (JP-A 63-107928, English Patent Publication No. 2260904 (GB 2260904-A)), a treating agent for psoriasis (JP-A 3-68009), a treating agent for diseases attributable to thromboxane A 2 production (JP-A 5-294834), a treating agent for eczema and dermatitis (JP-A 7-291868), etc., are being studied.

Respiratory tract infection is a disease which is established when pathogens invade into the respiratory tract by getting over its infection preventing mechanisms, and the treatment is mainly based on the improvement of respiratory tract clearance by using a bronchodilator, an expectorant, etc. But, in the case of acute exacerbation with infection, the main treatment is the use of a strong antibacterial agent against phlogogenic bacteria. However, most underlying diseases constantly becomes worse when acute exacerbation is repeated. Further, current treatments, which depend on antibacterial agents in the extreme, are under reconsideration owing to the emergence of resistant bacteria such as MRSA.

Recently, the usefulness of a low-dose long administration of erythromycin for a chronic lower airway infectious disease has been reported, and it attracts medical attention. A chronic lower respiratory infectious disease is a generic name for bacterial infections observed in chronic bronchitis, diffuse panbronchiolitis, bronchiectasis, etc., (sometimes, it includes bronchial asthma, chronic pulmonary emphysema, tuberculosis sequela, etc., accompanied by infection). Although these are different in the name of disease, it is known that all of the diseases take common morbid states such as purulent sputum in large amount, fatigue dyspnea and hypoxemia. Regarding the working mechanism of erythromycin, it is estimated that erythromycin's function does not based simply on its antibacterial activity, namely, erythromycin acts not on bacteria themselves, and it is understood that erythromycin acts rather on inflammatory cells which accumulate on the airway accompanying the bacteria, especially acts on neutrophils. That is, neutrophils are considered to infiltrate into tissues by the various kinds of stimulation caused by the infection to release protease as well as activated oxygen, and these substances cause epithelium damage, the trouble of ciliary movement and mucosa hypersecretion to exert a bad influence upon respiratory physiological effect, and erythromycin acts on these processes. Based on such consideration, a medicine, which suppresses the pulmonary tissue infiltration of neutrophils or suppresses the activity of neutrophils, can be useful as a treating agent for inflammatory dyspnea, for example, chronic lower airway infectious disease.

On the other hand, when the control of vitamin D production becomes abnormal due to diseases, etc. and the intracorporeal concentration increases to ex press physiological effect excessively, various diseases attributable to the excess of the vitamin D are developed. For example, it is known that, in sarcoidosis, vitamin D is excessively produce by a tumorigenic macrophage-like cell (J. Clinical Invest., 64, 218-225 (1979)), and as a result, hypercalcemia is developed. For the treatment of the disease, a glucocorticoid is mainly used, but the long term administration of a large amount of the glucocorticoid causes adverse reaction. On the other hand, vitamin D is known to exhibit its physiological effect via intracellular vitamin D receptors, and thereby a vitamin D 3 antagonist, which is specific to the expression of effect via receptor, is supposed to be effective in order to suppress the excessively developed vitamin D activity.

Incidentally, an active vitamin D 3 controls the amount of production of parathyroid hormone (henceforth, this may be referred to as PTH) in a living body, and the amount of production of PTH is lowered by the increase of the production of the active vitamin D 3 . Thereby, it is thought that the use of a vitamin D 3 antagonist corrects the decrease of PTH production attributable to the increase of active vitamin D 3 production, and further can accelerate the production of PTH. It is known that various diseases are caused by the decrease of PTH production, and one of the examples is hypoparathyroidism. The administration of PTH is considered to be ideal for the treatment of the disease; however, an orally administrable PTH preparation has not been developed yet. On the other hand, a vitamin D 3 antagonist is orally administrable, and thereby, the antagonist is supposed to be useful as an ideal treating agent for hypoparathyroidism.

Further, there are reports that PTH has effects on the growth and the differentiation of a cartilage cell, and the biosynthesis of cartilaginous matrix (Cellular and Calcium, 16, 112-122 (1994), and Calcified Tissue International, 50, 61-66 (1992)), on an osteoblast growth stimulating activity (Endocrinology, 118, 2445-2449 (1986)), on a collagen biosynthesis stimulating activity (J. Clin. Invest., 83, 60-65 (1989)) and the like. These reports show that PTH can become effective treating agents for metabolic disorder of cartilage and metabolic disorder of bone, and actually, a clinical investigation on osteogenesis is progressing by using an intramuscular injection preparation. However, an intramuscular injection preparation has such problems that the half life is short, and that hyperostosis, which is supposedly related to a transient increase in the intracorporeal concentration of PTH, is caused. On the other hand, a vitamin D 3 antagonist is orally administrable, and thereby it is supposed that the antagonist can solve these problems, and can be useful as an ideal treating agent for metabolic disorder of cartilage and that of bone.

A pharmaceutically effective dose of an active ingredient of the present invention depends on administration route, age and sex of the patient and the conditions of the disease, but it is ordinarily about 0.001-100 μg per day, preferably about 0.01-50 μg per day, and administration frequency is ordinarily 1-3 time per day. The pharmaceutical preparation is preferably prepared , so as to meet these conditions.

Further, treating agents of the present invention for various kinds of diseases can be administered in combination with conventional medicines.

Effectiveness for inflammatory respiratory diseases of vitamin D 3 derivatives expressed by the above formula (1) of the present invention has been demonstrated by experiments using lipopolysaccharide(LPS)-induced pneumonia hamsters, which are widely used as an inflammatory pulmonary disease model, as shown concretely in the below-mentioned examples. That is, it has been found that compounds of the present invention significantly suppress LPS-induced pneumonia by intra-respiratory tract administration or oral administration.

Effectiveness of vitamin D 3 derivatives expressed by the above formula (1) of the present invention for diseases attributable to the vitamin D 3 overactivity has been demonstrated based on the parameter of differentiation-inducing effect on HL-60 cells, as concretely shown in the below-mentioned examples. That is, the compound of the present invention specifically suppresses the differentiation of HL-60 cells induced by an active vitamin D 3 (1α, 25-dihydroxyvitamin D 3 ), and accordingly it becomes clear that the compound of the present invention acts as an antagonist to vitamin D 3 . Other vitamin D 3 derivatives expressed by the above formula (1) and having antagonistic effect to vitamin D 3 also can be screened by a similar evaluation system to that used in experimental examples.

On the other hand, it has been clarified that the blood calcium level-elevation effects of compounds of the present invention is extremely reduced compared with that of 1α, 25-dihydroxyvitamin D 3 although the generally most worried side effect of active vitamin D 3 compounds is the elevation of calcium level in blood. For example, the blood calcium level-elevation effects of compounds of the present invention in oral administration to rats, which are compared with that of 1α, 25-dihydroxyvitamin D 3 , are as shown below:

Compound No. 3105c; 1/>100

Compound No. 3405, 1/>100

Compound No. 5102, 1/259

Compound No. 5107, 1/11.

From the above results, it is thought that in vitamin D 3 derivatives expressed by the above formula (1), the separation of the development concentrations for anti-inflammatory effect and antagonistic effect to vitamin D 3 from that for blood calcium level elevation effect has been achieved, and side effect will not be generated.

Thus, treating agents containing vitamin D 3 derivatives expressed by the above formula (1) as active ingredients can be considered to be effective for inflammatory respiratory diseases or diseases attributable to the overactivity of vitamin D 3 .

By the way, it has been reported that an active vitamin D 3 has various effects on cell metabolism. Examples of such reports include the stimulation of maturation and differentiation of cell (Tanaka, et al., Biochem. J., 204, 713-719 (1982); Amento, et al., J. Clin. Invest., 73, 731-739 (1984); Colston, et al., Endocrinology, 108, 1083-1086 (1981); Abeetl, et al., Proc. Natl. Acad. Sci., 78, 4990-4994 (1981)) and immunosuppression effect such as interleukin-2 production inhibition (Rigbi, Immunology Today, 9, 54-58 (1988)). In addition, also immunology synergistic effect has been detected, and the stimulation of the production of bactericidal oxygen metabolites and the stimulation of leukocyte chemotactic response have been discovered.

It has been recognized that also vitamin D 3 derivatives expressed by the above formula (1) have the cell differentiation-inducing effect as mentioned above. This fact demonstrates that vitamin D 3 derivatives expressed by the above formula (1) have possibilities of therapies in various fields including, for example, malignant tumor, psoriasis, rheumatoid arthritis, inflammatory diseases such as dermatitis and autoimmune diseases, and other If therapies associated with supplementary agents in chemotherapy of infectious diseases (especially, bacterial, viral or fungus) and other therapies associated with mononuclear phagocyte.

Further, it is expected that vitamin D 3 derivatives expressed by the above formula (1) are also effective for the treatment of hypertension, the treatment of diabetes mellitus, the stimulation of hair growth and the treatment of acne, for which an active vitamin D 3 is effective as shown by the following reports: the treatment of hypertension (Lind, et al., Acta Med. Scand., 222, 423-427 (1987)), the treatment of diabetes mellitus (Inomata, et al., Bone Mineral, 1, 187-192 (1986)), the stimulation of hair growth (Lancet, March 4, 478 (1989)) and the treatment of acne (Malloy, et al., Tricontinental Meeting for Investigative Dermatology, Washington, 1989).

Some of vitamin D 3 derivatives of the present invention expressed by the above formula (1) are very high in bonding capacity to 1α,25-dihydroxyvitamin D 3 receptor, i.e. they have bonding capacities ranging from same degree to about {fraction (1/50)} of 1α, 25-dihydroxyvitamin D 3 , and high vitamin D 3 -like effects can be expected. In other words, compounds of the present invention are expected to be effective as an osteoporosis treating agent based on bon,e metabolism maintaining effect characteristic to an active vitamin D 3 .

Neutrophilic Infiltration Suppressing Effect Assayed by Using Hamster LPS-induced Pneumonia Model

A male golden hamster was placed in an inhalation chamber (volume: 12 liter) and allowed to inhale LPS (nebulizer filled concentration: 2.0 mg/ml) generated by an ultrasonic nebulizer for 30 min to cause pneumonia. Just after the inhalation of the LPS, a treating agent of the present invention was administered infratracheally at a dosage of 1 to 20 μg/kg under halothane anesthesia. After 24 hr, tracheal branches and pulmonary alveoli were washed, and the number of neutrophils in the washing was determined. Using the number of neutrophils obtained in the absence of the treating agent of the present invention as the control, the decreasing rates of the numbers of neutrophils were expressed in terms of percent suppression based on the control. The results are shown in Table 6-1.

Vitamin D 3 Antagonistic Effect Expressed by the Parameter of Differentiation Induction Effect on HL-60 Cell Caused by 1α,25-Dihydroxyvitamin D 3

(1) HL-60 cell line which had been purchased from a cell bank (Japanese Cancer Research Resource Bank, Cell No: JCRB0085) was used. The cell line was stored as a frozen storage stock to prevent the change of cell characteristics attributable to successive cultivations. Prior to the initiation of experiments, the cells were defrosted and successive culturing was stared, and such cells were used. For the experiments, cells whose successive culturing was from one month to about a half year were used. The successive culturing was carried out by centrifugally collecting cells which were in the state off suspension culture, and diluting the collected cell concentrate with a fresh culture medium at a ratio of about 1/100 (1-2×10 4 cells/ml). As the culture medium, an RPMI-1640 medium containing 10% fetal bovine serum was used.

(2) The cells which were being in the successive culturing in the above process (1) were centrifugally collected, and they were dispersed in a culture medium at the cell concentration of 2×10 4 cells/ml. The dispersion was seeded into a 24-well culture schale at 1 ml/well. In this system, 1α,25-dihydroxyvitamin D 3 , and compounds of the present invention, No. 4102a, No. 4107a and No. 4102b were each separately treated, and also the combinations of 1α,25 dihydroxyvitamin D 3 and one of the compounds of the present invention, No. 4102a, No. 4107a and No. 4102b were subjected to simultaneous treatments. 1α,25-dihydroxyvitamin D 3 , and compounds, No. 4102a, No. 4107a and No. 4102b were each dissolved in ethanol to prepare ethanol solutions having a concentration of 1×10 −6 M to 1×10 −3 M, and the solutions were each added at 1 μl/well. For the control, ethanol was added at 1 μl/well.: After culturing at 37° C. for 4 days in the presence of 5% CO 2 , the cells were centrifugally collected.

(3) As the parameter of differentiation induction effect on HL-60 cells, the induction of nitroblue tetrazonium (henceforth, NBT) reduction activity was used. The measurement of the NBT reduction activity was carried out according to the following procedure. That is, centrifugally collected cells were suspended in a fresh culture medium, and NBT and 12-O-tetradecanoylphorbol-13-acetate were added so that their concentrations became 0.1% and 100 nM, respectively. After the mixed suspension was incubated at 37° C. for 25 min, a cytospin sample was prepared. After air drying, it was stained with Kernechtrot, and the ratio of the positive cells of NBT reduction activity was determined under an optical microscope.

(4) The NBT reduction activities of the cells singly treated by the compounds of the present invention, No. 4102a, No. 4107a and No. 4102b are shown in Table 6-2. In the cells which were singly treated with each of these compounds of the present invention, the induction of NBT reduction activity was not recognized at all.
