The present invention relates to a novel sulfonamide compound or a salt thereof, or a derivative thereof useful as a prodrug. The present invention also relates to a medicament comprising said novel sulfonamide compound or a salt thereof, or a derivative thereof which is a prodrug as an active ingredient.
Movements of cells include contraction, migration, release, aggregation and the like, and phosphorylation of the myosin regulatory light chain is important for these cell movements. The myosin regulatory light chain is a subunit having a molecular weight of 20 kDa and constituting myosin, which exists in smooth muscle cells and various non-muscle cells such as neutrophils, platelets and nerve cells of warm-blooded animals (Non-patent document 1). Myosin existing in smooth muscle cells and various non-muscle cells such as neutrophils, platelets and nerve cells of warm-blooded animals is constituted by a myosin heavy chain subunit having a molecular weight of about 200 kDa, the myosin regulatory light chain subunit having a molecular weight of about 20 kDa, and a myosin constitutive light chain subunit having a molecular weight of about 17 kDa.
The myosin regulatory light chain is mainly phosphorylated by the myosin light chain kinase to increase the activity of myosin ATPase existing in the myosin heavy chain subunit (Non-patent document 2). It is known that the activated myosin having the increased ATPase activity becomes possible to interact with actin and activates movement apparatuses of cytoskeleton to activate cell movements. That is, it is known that activation of myosin relates to cell contraction (Non-patent document 3). It is also known that activation of myosin relates to change of cell morphology (Non-patent document 4). It is known that activation of myosin relates to cell migration (Non-patent document 5). Further, it is known that activation of myosin relates to cell release (Non-patent document 6: Kitani, S., et al., Biochem. Biophys. Res. Commun., 183, pp. 48-54, 1992). It is further known that activation of myosin relates to cell aggregation (Non-patent document 7). It is also known that activation of myosin relates to cell apoptosis (Non-patent document 8). Based on these findings, it is considered that an agent which inhibits the phosphorylation of the myosin regulatory light chain suppresses cell contraction, regulates change of cell morphology, suppresses cell migration, suppresses cell release, suppresses cell aggregation and suppresses cell apoptosis.
Cell contraction is deeply involved in diseases relating to contraction of various smooth muscle layers. Examples of such diseases include, for example, hypertension (Non-patent document 9), angina pectoris (Non-patent documents 10 and 11), cerebral vascular spasm (Non-patent documents 12, 13 and 10), erectile dysfunction (Non-patent document 14), bronchial asthma (Non-patent documents 15 and 16) and the like. Examples of the diseases relating to cell contraction also include orthopedic diseases, for example, diseases causing blood flow obstructions such as spinal canal stenosis, intervertebral disc herniation, posterior longitudinal ligament osteosis and stiffness in shoulder.
Change of cell morphology is deeply involved in diseases relating to morphological change of various cells. Examples of the diseases relating to change of cell morphology include, for example, as those relating to nerve cells of eyes, various nerve dysfunctions such as diabetic retinopathy, and glaucoma (Non-patent document 17). Further, cell migration is deeply involved in diseases relating to migration of various cells. Examples of such diseases include, for example, cancer invasion and metastasis (Non-patent documents 18 and 19), nephritis (Non-patent document 20) and the like.
Examples of diseases relating to regulation of change of cell morphology include, for example, diseases relating to nerve cells such as spinal cord injury, spinal canal stenosis, intervertebral disc herniation, intervertebral disc herniation lumbar vertebrae sequestration, lumbar vertebrae slippage, posterior longitudinal ligament osteosis, yellow ligament osteosis, Huntington disease, Parkinson's disease, amyotrophic lateral sclerosis, cerebellar ataxia, progressive supranuclear palsy, and multiple sclerosis.
Examples of diseases relating to regulation of change of cell morphology further include, for example, diseases relating to osteocytes and chondrocytes such as osteoporosis, rheumatoid arthritis, arthritis deformans, and osteogenesis imperfecta.
Furthermore, it is considered that cell release is deeply involved in various allergies and the like (Non-patent document 21), and further, cell aggregation is considered to be deeply involved in thrombosis and the like (Non-patent document 22). Further, it is known that cell apoptosis is involved in neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and glaucoma, viral diseases, hepatic diseases and the like (Non-patent document 23).
Examples of the diseases relating to cell release also include inflammatory diseases relating to release of various cytokines from inflammatory cells, such as rheumatoid arthritis, acute arthritis, chronic arthritis, arthritis deformans, and multiple sclerosis.
Among orthopedic diseases, diseases relating to abnormal cell migration include bone tumors, such as bone sarcoma, enchondroma, osteoid osteoma, chondrosarcoma, chordoma, and metastatic bone tumors.
As pathways for regulating phosphorylation of myosin regulatory light chain, two pathways are known, i.e., a pathway based on activation of myosin regulatory light chain kinase induced by elevation of intracellular calcium level, and a pathway based on inactivation of myosin dephosphorylation enzyme resulting from phosphorylation of the enzyme induced by activation of Rho kinase due to activation of low-molecular-weight Rho protein (Non-patent document 24).
That is, it is considered that compounds which inhibit Rho kinase suppress cell contraction, regulate change of cell morphology, suppress cell migration, suppress cell release, suppress cell aggregation, and suppress cell apoptosis, like medicaments which inhibit phosphorylation of myosin regulatory light chain.
Based on these findings, it is considered that a substance which inhibits Rho kinase is useful as an active ingredient of a medicament for prophylactic and/or therapeutic treatment of a disease relating to cell contraction, disease relating to change of cell morphology, disease relating to cell migration, disease relating to cell release, disease relating to cell aggregation, and/or disease relating to cell apoptosis.
As agents inhibiting the phosphorylation of myosin regulatory light chain, isoquinoline derivatives are known. For example, it has been reported that 1-(5-isoquinolinesulfonyl)-2-methylpiperazine (H-7) inhibits the phosphorylation of myosin regulatory light chain of mesenteric artery (Non-patent document 25), and there are also known drugs inhibiting the phosphorylation of myosin regulatory light chain of iris smooth muscle (Non-patent document 26), and astrocyte (Non-patent document 27). Further, 5-substituted isoquinoline derivatives are also known (Patent document 1). However, the N atom of sulfonamide in these 5-substituted isoquinoline derivatives does not form a ring, and thus they have a structure different from that of the compounds of the present invention. Further, tricyclic compounds are also known (Patent document 2). However, these compounds are tricyclic compounds and do not have sulfonamide, and therefore they are structurally different from the compounds of the present invention.
Further, known Rho kinase inhibitors also include the amide derivatives disclosed in Patent document 3; isoquinolinesulfonyl derivatives disclosed in Patent document 4, Non-patent document 28, and Patent document 5; heterocyclic amino derivatives disclosed in Patent document 6; indazole derivatives disclosed in Patent document 7; quinazoline derivatives disclosed in Patent documents 8 and 9, and the like. However, all of these compounds are structurally different from the compounds of the present invention.

The compounds of the present invention are novel compounds not described in literatures. The compounds of the present invention represented by the general formula (1) can be prepared by, for example, the following methods. However, the preparation methods of the compounds of the present invention are not limited to the following preparation methods.
In each reaction, reaction time is not particularly limited. Advance of the reactions can be readily monitored by the analysis means described later, and therefore the reactions may be terminated when yields of the objective substances reach the maximum.
The compound represented by the general formula (1) can be decomposed into a compound represented by the formula (4) and a compound represented by the formula (5) according to the following reaction route. Therefore, the compounds of the present invention can be prepared by the synthesis route reverse to the following reaction route.
For example, the compounds represented by the general formula (1) can be prepared by simultaneously or successively removing all the protective groups of a compound represented by the general formula (2) [in the formula, A, m, n, and Y have the same meanings as those defined above, G2a, G3a, G4a and G5a have the same meanings as those of G2, G3, G4 and G5 mentioned above, respectively, and one or more of these groups may be protected], or a compound represented by the general formula (2-a) [in the formula, A, m, n, G2a, G3a, G4a, G5a, and Y have the same meanings as those defined above, G1a is chlorine atom, hydroxyl group, an alkoxy group, or amino group, and these groups may be protected] (Step 1-1).

The compound represented by the aforementioned general formula (1) or a salt thereof per se may have a potent physiological activity such as Rho kinase inhibitory activity, and/or a metabolite thereof produced in vivo after administration to the living bodies may have a desired physiological activity such as Rho kinase inhibitory activity. More specifically, a compound or a salt thereof which functions as a prodrug when it is administered to a living body, i.e., a compound or a salt thereof which itself shows a weak physiological activity, but of which metabolite produced in vivo can exhibit a potent physiological activity such as the Rho kinase inhibitory activity, falls within the scope of the compound represented by the general formula (1) or a salt thereof. In this specification, the term “prodrug” means a compound that is metabolized, e.g., oxidized, hydrolyzed, or the like in living bodies, preferably in blood or live tissues, after oral administration or parenteral administration such as instillation to mammals, of which metabolite produced exhibits a desired pharmacological action. A compound or a salt thereof which itself has a sufficient physiological activity, and of which metabolite produced in living bodies exhibits comparable or more potent physiological activity such as Rho kinase inhibitory activity falls within the scope of the compound represented by the general formula (1) or a salt thereof. In the specification, such a compound is called a “prodrug-like compound”.
Furthermore, a prodrug which is not encompassed in the scope of the general formula (1) can be prepared by appropriately modifying a compound represented by the general formula (1) or a salt thereof, and such a prodrug also falls within the scope of the present invention.

The compounds of the present invention represented by the aforementioned formula (1) and salts thereof have cell movement inhibitory actions on the basis of the Rho kinase inhibitory action in the cells, and are useful as active ingredients of medicaments.
Among the cell movement inhibitory actions of the compounds of the present invention, the cell contraction inhibitory action can be confirmed by measuring vasoconstriction inhibitory activity, bronchus relaxation activity, intraocular pressure reducing activity, respiratory tract constriction inhibitory activity, or the like. The action to regulate change of cell morphology can be confirmed by, for example, measuring neurite outgrowth of retinal ganglion cells of eyes, or the like. The inhibitory action on cell migration (the action will be abbreviated as “cell migration inhibitory action”) can be confirmed by measuring neutrophil migration inhibitory activity, respiratory tract inflammation suppressing activity, or the like. The cell release inhibitory action can be confirmed by measuring the chemical mediator releasing amount from neutrophils. The cell aggregation inhibitory action can be confirmed by measuring platelet aggregation inhibitory activity, or the like. Further, the apoptosis inhibitory action can be confirmed by, for example, giving stimulation to induce apoptosis to cells and then measuring cell viability or occurring frequencies of morphological changes of cells characteristic to apoptosis such as nuclear condensation, nuclear fragmentation, and blebbing of cells. However, since the cell movement inhibitory actions on the basis of the Rho kinase inhibitory action in the cells are known to be associated with various biological actions as described in the section of background art in the specification, the aforementioned cell contraction inhibitory action, action to regulate change of cell morphology, cell migration inhibitory action, cell release inhibitory action, cell aggregation inhibitory action, and apoptosis inhibitory action should be construed to constitute a part of the actions of the medicament of the present invention.
More specifically, the compounds of the present invention represented by the aforementioned formula (1) and salts thereof have actions including the Rho kinase inhibitory action (see, Test Example 1 of the specification), intraocular pressure reducing activity (see, Test Example 3 in the specification), and the like. Further, it can be confirmed that the compounds of the present invention represented by the aforementioned formula (1) and salts thereof have an action for inhibiting the phosphorylation of myosin regulatory light chain (see, Test Example 2 of the specification), vasoconstriction inhibitory activity, activity for suppressing respiratory tract constriction induced by antigen stimulation, neutrophil migration inhibitory activity (see, Test Example 4 in the specification), respiratory tract inflammation suppressing activity, pulmonary inflammation suppressing activity, trachea relaxation activity, activity for suppressing respiratory tract constriction induced by a constriction elicitor, and the like. Therefore, the compounds represented by the aforementioned formula (1) and physiologically acceptable salts thereof as well as derivatives thereof useful as prodrugs are useful as active ingredients of medicaments for prophylactic and/or therapeutic treatment of diseases relating to contraction of various cells, diseases relating to morphological change of various cells, diseases relating to migration of various cells, diseases relating to release of various cells, diseases relating to aggregation of various cells, diseases relating to apoptosis of various cells, and the like.
Examples of the method for confirming that the compounds of the present invention represented by the aforementioned formula (1) and salts thereof have the Rho kinase inhibitory action include, for example, the following methods. However, the method is not limited to these methods.
Method 1: The activity of Rho kinase can be measured by, for example, the method disclosed in WO01/56988. More specifically, ATP (γ32P-ATP) is added to a substrate (Ribosomal S6 kinase substrate) together with a commercially available Rho kinase (Upstate) to start the enzymatic reaction and phosphorylate the substrate. The substrate is adsorbed on filter paper, and ATP is washed off with the phosphate buffer. Then, the amount of the phosphorylated substrate is measured by using a liquid scintillation counter. The inhibitory activity of the compounds of the present invention represented by the aforementioned formula (1) for the Rho kinase activity can be determined by adding the compounds before starting the enzymatic reaction, and measuring suppression of the phosphorylation amount of the substrate. The phosphorylation reaction of myosin phosphatase can be measured by, for example, using an antibody specifically recognizing the phosphorylated myosin phosphatase (Feng, J. et al., J. Biol. Chem., 274, pp. 37385-37390, 1999). More specifically, proteins including myosin phosphatase are extracted from a tissue, subjected to electrophoresis on acrylamide gel, and transferred to a nitrocellulose membrane. The proteins are reacted with antibodies specifically recognizing phosphorylated myosin phosphatase to detect the amount of phosphorylated myosin phosphatase. The inhibitory activity of the compounds of the present invention on the phosphorylation reaction of myosin phosphatase can be determined by adding the compounds before starting the extraction from the tissue, and measuring suppression of the phosphorylation amount of the myosin phosphatase.
Method 2: It is known that increase of the amount of phosphorylated myosin regulatory light chain activates the actomyosin system, which is a movement apparatus of cytoskeleton, and activates cell movements. Therefore, it is considered that the phosphorylation reaction of myosin regulatory light chain is important for cell movements (Kamm, K., et al., Annu. Rev. Physiol., 51, pp. 299-313, 1989; Niggli, V., FEBS Lett., 445, pp. 69-72, 1999; Itoh, K., et al., Biochim. Biophys. Acta., 1136, pp. 52-56, 1992; Kitani, S., et al., Biochem. Biophys. Res. Commun., 183, pp. 48-54, 1992). By measuring the amount of phosphorylated myosin regulatory light chain in the cells according to, for example, the method described in Test Example 2 of the specification, it can be confirmed that the compounds represented by the aforementioned formula (1) and salts thereof decrease the amount of phosphorylated myosin regulatory light chain in the cells.
It is known that the amount of phosphorylated myosin regulatory light chain in the cells is determined by activated states of two reaction routes including Reaction route 1 and Reaction route 2 described below (Fukata, Y., et al., Trends Pharmacol. Sci., 22, pp. 32-39, 2001).
Increase of intracellular calcium concentration→Activation of myosin light chain kinase→Increase of amount of phosphorylated myosin regulatory light chain
Activation of low molecular weight G protein Rho→Activation of Rho kinase→Phosphorylation (inactivation) of myosin phosphatase→Increase of amount of phosphorylated myosin regulatory light chain
It is considered that a compound that inhibits Reaction route 1 and/or Reaction route 2 mentioned above has an activity for decreasing the amount of phosphorylated myosin regulatory light chain. In order to estimate whether either or both of Reaction route 1 and Reaction route 2 mentioned above are the target site for the compounds of the present invention represented by the aforementioned formula (1) and salts thereof, effects of the compounds of the present invention represented by the aforementioned formula (1) and salts thereof on increase of intracellular calcium concentration and activity of myosin light chain kinase can be examined according to, for example, the methods described in Test Examples 5 and 6 of the specification. If it can be confirmed, as a result, that the compounds of the present invention and salts thereof give no influence on the increase of intracellular calcium concentration, and do not inhibit the myosin light chain kinase activity, it is readily presumed that the compounds of the formula (1) according to the present invention inhibit Rho kinase of Reaction route 2 mentioned above to decrease the amount of phosphorylated myosin regulatory light chain.
The compounds of the present invention represented by the aforementioned formula (1) and salts thereof inhibit Rho kinase. It is known that Rho kinase plays an important role for cell contraction and cell migration. Other than the above, it has been reported that Rho kinase controls a variety of cellular functions such as morphological change, aggregation, release, production, division, apoptosis, and regulation of gene expression in various cell lines (Fukata, Y., et al., Trends in Pharmacological Sciences, 22, pp. 32-39, 2001; Murata T., et al., J. Hepatotol., 35, pp. 474-481, 2001; Ohnaka, K., et al., Biochem. Biophys. Res. Commun., 287, pp. 337-342, 2001; Yuhong, S., et al., Exp. Cell Res., 278, pp. 45-52, 2002; Arakawa, Y. et al., BIO Clinica, 17(13), pp. 26-28, 2002; Inoue, M. et al., Nat. Med., 10 pp. 712-718, 2004).

A volume of 50 to 100 ml of peripheral blood collected from healthy volunteers is centrifuged by using Mono-Poly separator solution (Dainippon Pharmaceutical) to prepare a neutrophil containing fraction. The neutrophils are washed with PBS(−) and resuspended in Hanks' Balanced Salt Solution (HBSS+, Gibco) to prepare a cell suspension (8×106/ml). The cell suspension is diluted to 5×106/ml, introduced into Eppendorf tubes in a volume of 0.4 ml each, then 0.1 ml each of solutions of a test compound at various concentrations are added to the suspension and allowed to react at 25° C. for 5 minutes. After the reaction, 0.1 ml of trichloroacetic acid solution is added to each reaction mixture, the reaction mixture is gently shaken and centrifuged at 12,000 rpm (4° C., 5 minutes), the supernatant is removed, 3 μl of 1 M Tris solution is added to the residue, and the mixture is further mixed with 50 μl of extraction buffer (8 M urea, 0.02% 2-mercaptoethanol, 0.002% bromophenol blue) and left stand at room temperature for 1 hour. Then, the reaction mixture is loaded on a spin column (0.45 μm, Millipore) to remove the insoluble solids, a sample buffer for SDS polyacrylamide gel electrophoresis (25 mM, Tris-HCl pH 6.8, 2.5% 2-mercaptoethanol, 2% sodium dodecylsulfate, 5% sucrose, 0.002% bromophenol blue as final concentrations) is added, and 10 μl of each sample is subjected to electrophoresis.
The gel after the electrophoresis is blotted on a nitrocellulose membrane (BioRad), blocked with 5% skim milk, and reacted successively with antibodies pLC1 (Sakurada K. et al, Am. J. Physiol., 274, C1563-C1572 (1998)), which specifically recognize the phosphorylated myosin regulatory light chain, and donkey anti-mouse IgG (Chemicon) conjugated with horseradish peroxidase. The band of the phosphorylated myosin regulatory light chain is detected on a film by using ECL Plus Kit (Amersham Pharmacia Biotech). This band is subjected to quantification using a densitometer. By using this value, the inhibitory ratio (%) for phosphorylation of the myosin regulatory light chain is calculated by using the following equation.
Phosphorylation inhibition ratio (%)=1−(Band intensity of phosphorylated myosin regulatory light chain with addition of the test compound/Band intensity of phosphorylated myosin regulatory light chain without addition of the test compound)×100
Further, it is also possible to confirm the effectiveness of the compounds of the present invention by calculating the phosphorylation inhibition ratio with changing the concentration of the test compound, and obtaining a compound concentration providing an inhibition ratio of 50% as IC50.
A Japanese white rabbit having a body weight of about 2 kg was placed in a positioner and naturalized for one week before the experiment. An opthalmologic local anesthesant (Benoxil) was administered to both eyes, and then intraocular pressure was measured by using a tonometer (Classic 30, Solan). A 3 mM aqueous solution of a test compound was administered in a volume of 50 μl to the left eye, and the right eye was not treated (control eye). The intraocular pressure values were measured for the left and right eyes immediately before, and 2, 4 and 6 hours after the administration of the aqueous solution of the test compound, and the difference of the measured values for the left and right eyes was considered an intraocular pressure reduction value of the test medicament at each measurement time. The largest difference of the values for the left and right eyes among the measured values at the measurement times (after 2, 4 and 6 hours) was considered the maximum intraocular pressure reduction value (max IOP) of each test medicament. The intraocular pressure reducing degree representing the intraocular pressure reducing action of each test medicament was calculated according to the following formula. Since rabbits show significant daily variation of intraocular pressure, daily variation is added when change of intraocular pressure is measured over time, and the intraocular pressure reducing action may be overestimated. Therefore, we used this calculation method of intraocular pressure reduction value in order to minimize the influence of the variation.
Intraocular pressure reducing degree (%)=(max IOP/Intraocular pressure value immediately before administration)×100

It was demonstrated that the aforementioned compounds of the present invention reduced the rabbit normal intraocular pressure. In addition, even 6 hours after the administration of these compounds, the intraocular pressure reducing action did not disappear, and thus they had a sustained intraocular pressure reducing action.

The compounds, per se, metabolite thereof after administration, or both may exhibit the intraocular pressure reducing action.
Neutrophils are isolated from 50 to 100 ml of peripheral blood collected from healthy human donors by the method described in Test Example 2 to obtain a cell suspension (8×106/ml). Subsequently, solutions of a test compound at various concentrations are introduced into wells of a 96-well plate in a volume of 125 μl per well, the cell suspension of an equivalent volume is added to it and the plate is preincubated at room temperature for 5 minutes. During the preincubation, FMLP (1 μM, Sigma) solution is added to the lower chamber to set Boyden Chamber, the preincubated cell suspension is added to the upper chamber in a volume of 200 μl per well, and the cells are allowed to migrate at 37° C. under 5% carbon dioxide for 30 minutes. The filter after the migration is collected, and the non-migrated cells adhered to the surface that faced the upper chamber are carefully wiped off. Then, the migrated cells on the back surface are stained with DifQuick dye solution (International Reagents), washed with water and dried, and then absorbance is measured at 595 nm. The inhibition ratio against migration (%) of a test compound is calculated by using the following equation:
Migration inhibition ratio (%)=(1−Absorbance of the group with addition of test compound/Absorbance of the group without addition of test compound)×100
Further, it is also possible to confirm the effectiveness of the compounds of the present invention by calculating the phosphorylation inhibition ratio with changing the concentration of the test compound, and obtaining a compound concentration providing an inhibition ratio of 50% as IC50.
According to the method described in Test Example 2, a neutrophil containing fraction is prepared. Fura2-AM (Sigma) at a final concentration of 3 μM is added to the human neutrophil fraction and the mixture is incubated at 37° C. for 1 hour. After centrifugation (250 g for 5 minutes), the supernatant is discarded, and the neutrophils are resuspended in Hanks' Balanced Salt Solution (HBSS−, Gibco) to prepare a cell suspension (8×106/ml) for measurement of intracellular calcium concentration. The cell suspension for measurement of intracellular calcium concentration is left stand at room temperature for 30 minutes. Then, 490 μl of the cell suspension for measurement of intracellular calcium concentration is placed in a cuvette, 10 μl of calcium chloride solution at a final concentration of 1 μM is added to it and the cuvette is set in an intracellular calcium concentration analyzer (CAF110, Nippon Bunko). fMLP (Sigma) solution at a final concentration of 1 μM is added to the cell suspension, and F340 and F380, which are fluorescence intensity at 340 nm and 380 nm, respectively, are measured to obtain an R value (F340/F380) as an index of the intracellular calcium concentration. A test compound (1 μM) is added 3 minutes before the addition of FMLP, and the action on the intracellular calcium concentration is observed. By obtaining ratios of the maximum R value obtained with addition of each test compound relative to the maximum R value obtained without addition of test compound and taken as 100%, effect of the compounds of the present invention on the increase of the intracellular calcium concentration caused by the fMLP stimulation can be confirmed.
A myosin light chain kinase (MLCK) is purified from chicken gizzard smooth muscle by a conventional method (Yoshida, M., et al., J. Biochem., 99, 1027-1036 (1986)). The myosin regulatory light chain as a substrate is purified from the chicken gizzard smooth muscle by a conventional method (Grand, R. J., et al., Biochem. J., 211, 267-272 (1983)). The MLCK activity is measured by ELISA (Sakurada, K., et al., J. Biochem., 115, 18-21 (1994)) using anti-phosphorylated myosin regulatory light chain-recognizing antibodies (Sakurada, K., et al., Am. J. Physiol., 274, C1563-C1572, 1998). The myosin regulatory light chain is diluted in phosphate-buffered saline (PBS, Sigma) to a concentration of 5.0 g/ml, added to 96-well Immunoplate (Nunc) in a volume of 100 μl per well and left stand overnight at 4° C. Each well is washed with PBS, and 25 mM Tris/HCl buffer containing 100 μM ATP, 3 mM MgCl2, 1 mM CaCl2, 100 ng/ml of calmodulin (Sigma) and 100 ng/ml of MLCK (pH 7.4, Buffer A) is added to each well and incubated at 30° C. for 10 minutes. In a volume of 100 μl each of 20% aqueous phosphoric acid solution is added to each well to terminate the enzymatic reaction. Each well is washed with 25 mM Tris/HCl buffer (TTBS) containing 0.1% Tween 20, and then 100 μl of antibodies specifically recognizing phosphorylated myosin regulatory light chain (Sakurada, K., et al., Am. J. Physiol., 274, C1563-C1572, 1998) is added to each well and incubated at room temperature for 90 minutes.
Each well is washed with TTBS, and then 100 μl of the HRP-labeled anti-mouse IgG antibodies (Bio-Rad) are added to each well and incubated at room temperature for 90 minutes. Each well is washed with TTBS, and then 25 mM citrate buffer (pH 5.0) containing orthophenylenediamine (Sigma) as a substrate of HRP and aqueous hydrogen peroxide (0.03%) is added in a volume of 100 μl per well and incubated at room temperature for 5 minutes. 50 μl of 4 N sulfuric acid is added to each well to terminate the reaction, and then absorbance is measured by using an immunoplate reader (Bio-Rad). By calculating the MLCK activity inhibition ratio after addition of a test compound to Buffer A at various concentrations to obtain a compound concentration providing an inhibitory ratio of 50% as IC50, effect of the compounds of the present invention on MLCK activity can be confirmed.

From these results, it was confirmed that intraocular pressure reducing action was enhanced in rabbits by combination of the compound of the present invention exemplified with the 19-1 compound and a carbonic anhydrase inhibitor, a prostaglandin-related drug, or an adrenergic receptor β blocker. Moreover, the compounds of the example numbers 1-3, 4-1, 10-3, 19-3 and the like can also be evaluated by the same methods as those of Test Examples 7-1 and 7-2 to confirm the effectiveness thereof.
Moreover, it is also possible to confirm the effectiveness of the compounds of the present invention indicated with the example numbers mentioned in Test Examples 3 other than the 19-1 compound by performing the test using the compounds in combination with a carbonic anhydrase inhibitor, a prostaglandin-related drug, or an adrenergic receptor β blocker.
Furthermore, by performing a test in which the compositions A to C described in Preparation Example 1, the compositions E to G described in Preparation Example 2, and compositions comprising, in combination, the aforementioned example compounds and a drug for combination use are administered as the combination use group instead of successively instilling a solution of the compound of the present invention and a drug for combination use, the effectiveness thereof can be confirmed.
On the basis of the results mentioned above, it was revealed that medicaments consisting of the compounds of the present invention and drugs for combination use were useful as medicaments for prophylactic and/or therapeutic treatment of glaucoma.
For evaluating the intraocular pressure reduction enhancing action of a combination of the compound of the present invention and latanoprost (trade name: Xalatan, Pfizer) as a prostaglandin related drug, the action can be demonstrated by using a monkey (cynomolgus monkey).
Although the effect of the combination use is demonstrated by using the 19-1 compound for the test example, the effect is not limited to the 19-1 compound, and the ophthalmic solution concentration of the 19-1 compound is not limited to those used in this test example. Moreover, as for the test compound used for combination use, similar effect can be obtained also with the compounds of the present invention represented with the example numbers mentioned in Test Example 3. The test is performed by using cynomolgus monkeys sufficiently naturalized for the operation of fixation on a monkey chair and ophathalmotonometry.
As the test compound, the 19-1 compound is dissolved in physiological saline, and the solution is neutralized by addition of sodium hydroxide (pH 7.0 to 8.0) to prepare a 0.01 weight % aqueous solution (19-1 compound aqueous solution). As a drug for combination use, latanoprost (trade name: Xalatan, Pfizer) is used as the marketed formulation per se. The test aqueous solution or the drug for combination use is instilled to the left eye, and the right eye is not treated (control eye). The test groups consist of (1) control group, (2) group instilled only with the 19-1 compound aqueous solution (single drug group 1), (3) group instilled only with the drug for combination use (single drug group 2), and (4) group instilled with the drug for combination use and the 19-1 compound aqueous solution (combination use group). After initial intraocular pressure values of the monkeys are measured for each group, 30 μL of physiological saline is instilled to the control group, single drug group 1, and single drug group 2, and latanoprost is instilled in the same volume to the combination use group. Then, 5 minutes after the instillation of physiological saline or latanoprost, 30 μL of physiological saline is instilled to the control group, the same volume of the 19-1 compound aqueous solution is instilled to the single drug group 1, and the combination use group, and 30 μL of the drug for combination use is instilled to the single drug group 2. Then, the intraocular pressure is measured over time for each group.
In Test Example 8, the 19-1 compound exhibits the intraocular pressure reducing action in the single drug group 1 in a degree exceeding that of the control group, and the intraocular pressure reducing action in the combination use group in a degree exceeding those of both the single drug group 1 and single drug group 2. It is thereby confirmed that the intraocular pressure reducing action is enhanced in monkeys by combining the compound of the present invention and a prostaglandin-related drug. Moreover, the compounds of the example numbers 1-3, 4-1, 10-3, and 19-3 can also be evaluated by the same method as that of Test Example 8 to confirm the effectiveness thereof.
Moreover, it is also possible to confirm the effectiveness of the compounds of the present invention indicated with the example numbers mentioned in Test Examples 2 other than the 19-1 compound by performing the test using the compounds in combination with a prostaglandin-related drug.
Furthermore, by performing a test in which the composition D described in Preparation Example 1, the composition H described in Preparation Example 2, and compositions comprising the aforementioned example compounds and latanoprost in combination are administered as the combination use group instead of successively instilling a solution of the compound of the present invention and latanoprost, the effectiveness thereof can be confirmed.
Based on the above, it can be revealed that medicaments consisting of the compounds of the present invention and latanoprost are useful as medicaments for prophylactic and/or therapeutic treatment of glaucoma.

The weight of each mouse was measured, a test compound solution was orally administered in a volume corresponding to 10 ml/kg, and only distilled water was administered to the control group. Each group consisted of five to seven animals. LPS was dissolved in physiological saline, and intraperitoneally administered to each mouse in an amount of 5 μg. The test compound was administered first, and LPS (lipopolysaccharide, Sigma) was administered 60 minutes later. After 90 minutes, blood was collected from the abdominal large vein in the presence of heparin, and plasma was obtained by centrifugation.

A Lab-Tek culture slide (4-well) was coated with poly-L-lysine (Sigma). A pregnant Wistar rat was used, and anesthetized with ether on day 18 of gestation. Then, a rat fetus was taken out from the rat, and the hippocampus was extracted from the brain of the fetus, put into a phosphate buffered physiological saline containing 0.1% trypsin, and incubated at 37° C. for 10 minutes. The hippocampus precipitated by centrifugation was ground in a medium containing 10% heat-inactivated fetal bovine serum by using a pipet to obtain hippocampus nerve cells. The cells were finally suspended in a medium containing B27 Supplement (Gibco), and plated on the preliminarily coated Lab-Tek culture slide at a density of 50,000 cells/well. After adhesion of the cells (about 2 hours), a drug was added at a desired concentration, and the slide was further incubated at 37° C. for 22 hours under 5% CO2. An a control, the same volume of the phosphate buffered saline as the solvent was added.
After the incubation, the cells were fixed with 4% paraformaldehyde, and immunostained by using rabbit anti-beta-III-tubulin antibodies (Covance). Images of the nerve cells were captured into a computer by using a digital camera (DP-70, Olympus) installed in a fluorescence microscope (Olympus). Images of 20 to 30 of arbitrary sites on the slide were captured, and lengths of the axial fivers of 200 to 300 nerve cells were measured by using NIH imaging software for each drug. The neurites of nerve cells treated with the compound of the present invention, represented by the compound of the example number of 36-1, were extended by 28% at a concentration of 1 μM, and 43% at a concentration of 10 μM, compared with the lengths of the neurites of non-treated nerve cells.
It was confirmed that the compounds of the present invention had a neuronal regeneration, and they are useful as medicaments for prophylactic and/or therapeutic treatment of a disease which needs nerve restoration such as spinal cord injury.
The neurite outgrowth of other compounds of the present invention can be confirmed by using the same procedure.
An experiment for Inhibitory effect on neurite retraction using mouse neuroblastoma cell strain N1E-115 was performed according to the method of Hirose, M. et al. (J. Cell. Biol., 141, pp. 1625-1636 (1998)). This method utilizes the fact that LPA (lysophosphatidic acid), which is a endogenous substance, induces neurite retraction, and is a method of evaluating how much a drug can inhibit the LPA-induced neurite retraction and thereby evaluating potency of inhibition of neuronal degeneration and potency of neuronal regeneration of the drug. N1E-115 cells cultured in a DMEM solution containing 20% heat-inactivated fetal bovine serum were plated on a 6-well plate (IWAKI) at a density of 40,000 cells/well, and cultured overnight at 37° C. in the same culture medium in a 5% CO2 incubator. In order to induce differentiation of the N1E 115 cells into nerve cells, the culture medium was changed to the serum-free DMEM solution, and the cells were cultured for 1 or 2 days at 37° C. in the 5% CO2 incubator until most of the cells extended the neurites. On the examination day, each compound of the present invention was added at a final concentration of 10 μM, incubation was performed for 30 minutes, then LPA (Sigma) was added at a final concentration of 1 μM, and incubation was further performed for 10 minutes. To the control, the same volume of phosphate buffered saline as the solvent was added. After completion of the incubation, glutaraldehyde was added at a final concentration of 5% to fix the cells. Not less than 200 of cells were observed with a microscope, and ratio of rounded cells which did not have neural spines to the total cell count (rounded cell percentage, RCP) was obtained. The inhibition rate (%) of each drug was calculated by using the following equation.
Inhibition rate (%)=100−(RCP obtained with drug to be evaluated−RCP of control)/(RCP obtained with LPA−RCP of control)×100

Further, in the nerve cells treated with 10 μM of the compounds of the present invention exemplified with the example number of 8-3, 32-2, 39-1, 40-1 and 42-1, the LPA-induced neurite retraction was inhibited by 50% or more.
It was confirmed that the compounds of the present invention had an inhibitory effect on neuronal degeneration and an effect of neuronal regeneration, and they were useful as medicaments for prophylactic and/or therapeutic treatment of a disease which requires a repair of neuron such as spinal cord injury and spinal canal stenosis.
Examination of rat vascular smooth muscle relaxing action was performed as follows. A rat was anesthetized with pentobarbital sodium, and bled from the carotid artery, and then the thoracic aorta was extracted. The extracted vessel was immersed in ice-cooled Krebs-Henseleit nutrient solution bubbled with a mixed gas of 95% O2+5% CO2 to wash out the blood in the internal cavity of the vessel with the nutrient solution, and then stored overnight in the nutrient solution at 4° C. Then, connective tissues and lipids were removed from the vessel under a stereoscopic microscope, and a ring sample having a width of about 3 mm was prepared. The ring sample was hung in an organ bath containing the nutrient solution of 37° C., and a resting tension of 2.5 g was loaded on the sample. After the ring sample was stabilized for about 90 minutes, it was confirmed that a contraction reaction could be obtained by addition of 60 mM KCl alone. A test drug was added to the nutrient solution at an appropriate final concentration, and incubation was performed for 10 minutes. Then, phenylephrin was cumulatively added so that the concentration should become 1 nM, 10 nM, 100 nM, 1 μM and 10 μM. Contraction ratio was obtained as a reaction rate (%) of the ring sample added with the drug at the time of the cumulative addition of phenylephrin based on the maximum contraction obtained with 60 mM KCl, which was taken as 100%, and IC50 value of each drug was obtained from a concentration-reaction rate curve. As a result, IC50 values of the compounds of the example numbers of 19-3 and 36-1 were 0.3 and 0.1 μM, respectively.
It was confirmed that the compounds of the present invention had a potent vascular smooth muscle relaxing action, and they were useful as medicaments for prophylactic and/or therapeutic treatment of a disease originating in blood flow obstruction such as spinal canal stenosis.
A rat spinal cord injury model is prepared as follows. A rat is anesthetized with pentobarbital sodium, shaved on the back, and fixed in the abdominal position. After disinfection on the back with Isodine Surgical Scrub (Meiji Seika), the thorax is cut open along the median to expose the thoracic vertebrae. The 9th and 10th thoracic vertebrae are excised to expose the spinal cord. A traumatic injury is added to the spinal cord by using an impactor (NYU impactor or IH impactor) to obtain a spinal cord injury model. Benzylpenicillin potassium (Crystalline Penicillin G Potassium Meiji, Meiji Seika) is dropped on the opened lesion and intramuscularly injected in the femoral region for the purpose of evasion of infectious diseases. The muscles and skin of the opened lesion are sutured with a ligature, and Isodine Surgical Scrub is applied to the sutured portion. A compound of the present invention as a test compound is continuously administered to the injured site by using an osmotic pressure pump (Alzet). Alternatively, the test compound is repeatedly administered to a peripheral part. To a control, solvent alone is administered.
Recovery of hindlimb motor function can be observed by using a BBB scale (The Basso, Beattie and Bresnahan (BBB) locomotor rating scale). As for evaluation of neural regeneration, effectiveness of the compound of the present invention can be confirmed by injecting BDA (Biotin Dextran Amine) into the cerebral cortex as a marker, extracting the spinal cord including damaged area two weeks later, and observing whether the marker is recognized on the caudal side from the damaged area in the corticospinal tract (efferent path) by immunohistological staining.
A rat spinal canal stenosis (cauda equina compression-induced walking dysfunction) model can be prepared according to the method of Nakai, K et al. (Anesth. Analg., 94, pp. 1537-1541 (2002)) or the like. Namely, a rat is anesthetized with pentobarbital sodium, shaved on the back, and fixed in the abdominal position. After disinfection on the back with Isodine Surgical Scrub (Meiji Seika), a lumbar part is cut open along the median to expose the spine. Then, a silicone rubber of 1×4×1.5 mm (height×length×width) is inserted into the fifth lumbar vertebral canal from a small hole on the vertebral arch. Benzylpenicillin potassium (Crystalline Penicillin G Potassium Meiji, Meiji Seika) is dropped on the opened lesion and intramuscularly injected in the femoral region for the purpose of evasion of infectious diseases. The muscles and skin of the opened lesion are sutured with a ligature, and Isodine Surgical Scrub is applied to the sutured portion. Animals of sham group are also prepared according to the aforementioned method, provided that silicone rubber is not inserted.
In walking ability test, evaluation is performed by using a treadmill (Muromachi Kikai). A rat is placed on a traveling belt, adapted to the environment more than 3 minutes under a grid-electrified condition (0.04 to 4 mA), and then made to start walking from a velocity of 10 m/min, and then the velocity is increased by 5 m/min every 3 minutes. The walk is stopped, and electrical stimulation (0.04 to 4 mA) is applied to the rat which has moved to the grid for electrical stimulation provided before the traveling belt. Distance which the animal walked after the animal started the walk until the animal became unable to walk, i.e., the animal came not to walk even if a stimulation (sound, contact, electricity) was added to the animal to urge it to walk, was calculated from the walking time. Before the operation, the walking function test is carried out 3 times to perform training of walk. From the 4th day after the operation, repetitive administration of each compound of the present invention as a test compound was started, and the walking ability test was performed on the 14th day of the administration for the measurement.
Each group consisted of 7 or 8 animals, and the average distance before the administration was the average for the animals of both groups. As a result, the compounds of the present invention exemplified with the example numbers of 8-1, 8-3, 19-3, 36-1, and 57-1 extended the walk distance, and thus improved the walking dysfunction, compared with the solvent repetitive administration group. It was confirmed that the compounds of the present invention were useful as medicaments for therapeutic treatment of a disease accompanied by walking dysfunction such as spinal canal stenosis.
A rat experimental autoimmune encephalomyelitis (EAE) model (Clinical Immunology Illustrated, pp. 112-117, Ed. by Brostoff, Scadding, Male, and Roitt, Supervised and Translated by Hirose, T., Karino, S., Tada, T., Nankodo, 1994) is used.
The model is prepared by injecting Freund's complete adjuvant containing guinea pig myelin basic protein (GPMBP) and Mycobacterium tuberculosis (MTB) cells as a sensitizing substance for inducing the disease to sole of a 4-week old Lewis rat. The aforementioned adjuvant containing 5 μg of GPMBP and 200 μg of MTB is injected per rat. After the administration of the sensitizing substance, repetitive administration of a compound of the present invention as a test compound is started. Symptoms of the disease are evaluated according to the following method. The day of the injection of the sensitizing substance is defined day 0, and symptoms of the rat are observed every day. Symptoms are numerized as follows: no symptom=0, hypotonia of tail end=0.5, hypotonia of whole tail=1, ataxia=2, paralysis of both hindlimbs=3, paralysis of forelimbs: 4, and death=5, and these numerals are recorded as clinical scores. The effectiveness of the compound of the present invention can be confirmed by observing improvement of these clinical scores.
