Patent Application
20060009439
The present invention relates to a 12-membered ring macrolide compound useful as a medicament, preparation thereof and use thereof.
Compounds having cytotoxicity have been used as antitumor agents, and many screenings have been carried out using cytotoxicity as an index. As a result, most of pre-existing antitumor agents give affection to cancer cells and simultaneously to normal tissues in which a proliferation of cell is active, for example, to bone marrow, intestine epithelium and the like. Thus, the improvement of QOL of patients has not been sufficiently accomplished yet.
Further, although it can be expected that treatments by the antitumor agents are rather effective for leukemia, it cannot be always said that they are effective for solid cancer. Therefore strong demands have been made to provide antitumor agents that are effective for solid cancer and are highly safe.
Screenings for fermentation products of microorganism have been carried out using the cytotoxicity in vitro as an index, expecting that they might also be used as antitumor agents. Many compounds having cytotoxicity have been found, however, most of them show cytotoxic activities only in vitro, and few compounds of them show antitumor activities in vivo, and very few compounds exhibit effectiveness for solid cancer.
It is the object of the present invention to find out compounds which show antitumor activity not only in vitro but also in vivo and have antitumor activities for solid cancer from fermentation products of microorganism or derivatives thereof.
It is considered that tumorgenesis of a normal cell is caused by mutation of a gene in the cell occurs and an abnormal gene is expressed. Accordingly, the present inventors have made intensive investigations based on the inference that the growth of a tumor cell can be suppressed by changing the gene expression of the tumor cell, namely, the growth of the tumor cell can be controlled by changing the gene expression of oncogene or tumor suppressor gene, or by changing the gene expression involved in cell cycle. The present inventors have considered that a compound changing of the gene expression, in particular, a compound suppressing VEGF (vascular endothelial growth factor) production at a hypoxic condition could suppress angiogenesis by a tumor and has an antitumor activities for solid cancer. Then, they carried out screening for fermentation products of microorganism and derivatives thereof using the VEGF production by U251 cell under hypoxic stimulation as an index. As the results, the inventors have found out novel physiologically active compounds, 12-membered ring macrolide compounds, named 11107 and analogues thereof which suppress the VEGF production at a hypoxic condition in vitro, and further suppress the growth of solid tumor cells in vivo.
The present inventors have further found that 11107D among the 11107 analogues is stable even in an aqueous solution, and that compounds obtained by chemical modifications of 11107D (hereinafter, these are referred to as 11107D derivatives) inherit the property of stability in an aqueous solution from 11107D and inhibit the growth of solid tumor cells in vivo experiments in much more degree. The present invention has been accomplished based on these findings.
As a related art of a 12-membered ring macrolide compound which is most structurally similar to the compounds of the present invention, a 12-membered ring macrolide compound FD-895 (JP-A 4-352783) represented by the formula (XIV):
is mentioned. The publication discloses that FD-895 has in vitro cell growth inhibitory activities against P388 mouse leukemia cell, L-1210 mouse leukemia cell and HL-60 human leukemia cell in RPM-1640 medium (column 6, Table 2). However, it has been reported that FD-895 did not show antitumor activities in an in vivo experiment using P388 mouse leukemia cell (Seki-Asano M. et al, J. Antibiotics, 47, 1395-1401, 1994).
In addition, FD-895 is unstable in an aqueous solution as described later and is expected to be inappropriate to mix with an infusion solution upon administration. Thus, it cannot be said that FD-895 has sufficient qualities as an antitumor agent.

2. Fermentation Method of Producing Microorganism
The physiologically active substance 11107D according to the present invention can be produced by inoculating the strain on a nutrition source medium and carrying out aerobic fermentation. The strain for producing the physiologically active substance 11107D is not limited to the above-mentioned strain, and any strain belonging to the genus Streptomyces and having an ability of producing 11107D can be used in the present invention.
The fermentation method of the above-mentioned microorganism is according to the general fermentation method of microorganism, but it is preferably carried out under aerobic conditions such as shaking culture or aeration-agitation fermentation using liquid medium. The medium used for culture may be a medium containing a nutrition source which can be utilized by microorganism belonging the genus Streptomyces, therefore all of various synthetic, a semi-synthetic medium, an organic medium and the like can be utilized. As the carbon source in the medium composition, there can be used a single or a combination of glucose, sucrose, fructose, glycerin, dextrin, starch, molasses, soybean oil and the like. As the nitrogen source, there can be used a single or a combination of organic nitrogen sources such as pharma media, peptone, meat extract, soybean powder, casein, amino acid, yeast extract and urea, and inorganic nitrogen sources such as sodium nitrate and ammonium sulfate. Additionally, for example, there can be added and used salts such as sodium chloride, potassium chloride, calcium carbonate, magnesium sulfate, sodium phosphate, potassium phosphate and cobalt chloride; heavy metal salts, vitamins such as vitamin B or biotin, if necessary. Further, when foaming is remarkable during culture, various defoaming agents can be appropriately added in the medium as necessary. When the defoaming agent is added, it is required to set at a concentration for not adversely affecting the production of an objective substance, and for example, the use concentration is desirably 0.05% or less.
The culture condition can be appropriately selected within the range at which the microbial strain grows well and can produce the above-mentioned substance. For example, the pH of a medium is about 5 to 9, and preferably nearby neutral in general. The temperature of fermentation is usually kept at 20° C. to 40° C. and preferably 28° C. to 35° C. The fermentation period is about 2 to 8 days, and usually about 3 to 5 days. The above-mentioned fermentation conditions can be suitably changed in accordance with the kind and property of microorganism used, external conditions and the like, and it is needless to say that an optimum condition can be selected. The physiologically active substance 11107D of the present invention which was accumulated in the cultured broth can be collected by usual separation procedures utilizing its property such as a solvent extraction method and an absorbing resin method.
The physiologically active substance 11107D can also be prepared, for example, by using a microorganism belonging to the genus Streptomyces (for example, Streptomyces sp. AB-1704 strain (FERM P-18999)) and using 11107B substance (the compound described in Example A4 of WO 02/060890, as shown in Referential Examples 6 to 10.

The hydroxyl groups of 11107D can be selectively protected by selecting the reagent and equivalence thereof for use in the protection of the hydroxyl groups. For example, a compound in which the hydroxyl groups at the 3-position and 21-position are selectively protected can be obtained by carrying out the reaction at room temperature using chlorotriethylsilane, triethylamine and 4-dimethylaminopyridine in dichloromethane or using tert-butylchlorodimethylsilane and imidazole in N,N-dimethylformamide. In this procedure, for example, the hydroxyl group at the 3-position can be selectively protected by controlling the equivalence of chlorotriethylsilane or tert-butylchlorodimethylsilane. Further, it is possible that two or three of the four hydroxyl groups are protected by a silyl group, and then the other two or one hydroxyl group is protected by the above-mentioned ethoxyethyl or the like.

More specifically, the hydroxyl groups of the compound (IA) other than the hydroxyl group at the 7-position can be converted into carbonic ester groups by the same way as the hydroxyl group at the 7-position by treatment with a base and a chloroformate derivative in equivalents corresponding to the number of hydroxyl groups to be converted into carbonic ester groups.

The step A5 is a step for producing the compound of the formula (VA). This step is carried out by subjecting the urethane derivative of the formula (IVA) to a deprotection treatment mentioned below in an inert solvent.

The results show that the content of FD895 decreased to 83% after 24 hours, but that the contents of Compounds 9, 12 and 22 as representative compounds of the compounds of the formula (I) remained 95 to 96%, indicating that the 11107D derivatives are stable in an aqueous solution.
As is evident from the above Pharmacological Test Examples, the compounds of the formula (I) according to the present invention especially suppress VEGF production by varying the gene expression and are expected to use as an antitumor agent, in particular, as a treating agent for solid cancer, a carcinoma metastasis suppressor, as well as an agent for treating diabetic retinopathy, rheumatoid arthritis and anginoma. Further, as is evident from the toxicity test of Test Example 4, the compounds of the formula (I) show growth inhibitory activities in the WiDr human colon tumor modle in such a dose as to not cause remarkable weight loss of the tested mice and are safe compounds. Accordingly, they are efficacious as an agent for preventing or treating a disease against which gene expression control is efficacious, a disease against which VEGF production suppressing activity is efficacious and a disease against which angiogenesis inhibiting activity is efficacious. The “preventing or treating” indicates either of preventing or treating, or both of them. More specifically, the compounds of the formula (I) of the present invention are effective as an antitumor agent, and in particular, as an antitumor agent and a carcinoma metastasis suppressor for solid cancer. As the solid cancer, for example, pancreatic cancer, gastric cancer, colon cancer, breast cancer, prostate cancer, lung cancer, kidney cancer, brain tumor, head and neck cancer, esophageal cancer, skin cancer, liver cancer, uterus cancer, cervix uteri cancer, urinary bladder cancer, thyroid cancer, testicular cancer, chorionic carcinoma, osteosarcoma, soft tissue sarcoma, and ovarian cancer may be proposed, of which a cancer such as colon cancer, breast cancer, prostate cancer, lung cancer, head and neck cancer or ovarian cancer is preferred. Further, they are also effective as an antitumor agent for leukemia. Further, they are also effective as an agent for treating hematoma. Furthermore, they are also effective as an agent for treating diabetic retinopathy, rheumatoid arthritis and hematoma, which is based on VEGF production suppressing action. In addition, they are also effective as an agent for treating inflammatory diseases consisting of osteoarthritis, psoriasis and prolonged hypersensitivity reaction, and atherosclerosis.
When the compounds are prepared as an injection, a pH regulator, a buffer, a stabilizer, a solubilizer and the like are added to the main drug, if necessary, to prepare an subcutaneous, intramuscular, intra-articular or intravenous injection according to a conventional procedure.
When the compound is administered as a preventive or therapeutic agent for various diseases, it may be orally administered as tablets, powders, granules, capsules, syrups and the like, and may be parenterally or parenterally administered as a spray, a suppository, an injection, an external preparation or a drip. The dose remarkably varies according to the severity of symptom, age, the kind of liver disease etc., and approximately 1 mg to 100 mg per day for an adult is administered in general at one time or several times.
Conventional excipients are used at production of pharmaceuticals, and the pharmaceutical products are prepared by a conventional method. Namely, when a solid formulation for oral use is prepared, a filler is added to the main drug, and if necessary, a binder, a disintegrant, a lubricant, a colorant, a flavoring agent and the like are added thereto, and then tablets, coated tablets, granules, powders, capsules and the like are prepared. It is needless to say that sugar coating, gelatin coating or suitable coating may conducted on the tablet and granule, if necessary.
According to the present invention, the compounds of the formula (I) of the present invention suppress, in particular, VEGF production by varying the gene expression and show excellent antitumor activities in in vivo solid tumor models. Further, the compounds of the formula (I) of the present invention are stable in an aqueous solution and can provide, for example, an agent for treating cancer, in particular, an agent for treating solid cancer, a carcinoma metastasis suppressor, an agent for treating diabetic retinopathy, rheumatoid arthritis and angioma.

To a solution of Compound 12-2 (8E,12E,14E)-6-(1-ethoxyethoxy)-3,16,21-trihydroxy-6,10,12,16,20-pentamethyl-7-((4-methylpiperazin-1-yl)carbonyl)oxy-18,19-epoxytricosa-8,12,14-trien-11-olide (364 mg, 0.489 mmol) obtained in the second step in a mixture of tetrahydrofuran:2-methyl-2-propanol=1:1 (10 mL) was added pyridinium p-toluenesulfonate (184 mg, 0.734 mmol), and the reaction mixture was stirred at room temperature for 19 hours. After triethylamine (75 mg, 0.734 mmol) was added dropwise to the reaction mixture, the mixture was evaporated. The resulting residue was dissolved in ethyl acetate and washed with a saturated aqueous solution of sodium bicarbonate. The organic layer was dried over anhydrous magnesium sulfate, filtrated and evaporated. The resulting residue was purified by silica gel column chromatography (Fuji Silysia, NH Silica gel, 200 to 350 mesh; ethyl acetate-hexane-methanol, 1:1:0 to 2:1:0 to 4:1:0 to 1:0:0 to 39:0:1 to 29:0:1 to 19:0:1). The crude purified fraction was evaporated, and the residue was purified by thin layer chromatography (Fuji Silysia, NH Silica gel Plate; methanol-dichloromethane, 1:29) to give the title compound (286 mg, 92%) as a colorless oil.

After stirring, it was frozen at −70° C. to give a frozen seed culture. The frozen seed culture was melted, 0.25 mL thereof was inoculated into a 250 mL Erlenmeyer flask containing 25 mL of a seed medium [2% of soluble starch, 2% of glucose, 2% of soybean meal (ESUSAN-MEAT manufactured by Ajinomoto Co., Ltd.), 0.5% of yeast extract (manufactured by Oriental Yeast Co., Ltd.), 0.25% of sodium chloride, and 0.32% of calcium carbonate, pH 7.4 before sterilization], and it was cultured at 28° C. for two days in a shaking incubator to give a seed culture. Further, the seed culture (0.5 mL) was inoculated into a 500 mL Erlenmeyer flask containing 100 mL of production medium [2% of soluble starch, 2% of glucose, 2% of soybean meal (ESUSAN-MEAT manufactured by Ajinomoto Co., Ltd.), 0.5% of yeast extract (manufactured by Oriental Yeast Co., Ltd.), 0.25% of sodium chloride, and 0.32% of calcium carbonate, pH 7.4 before sterilization], and it was cultured at 28° C. for three days in a shaking incubator.
Each of the resulting cultures (100 mL/500 mL Erlenmeyer flask, 10 flasks) was subjected to centrifugation at 3000 rpm for 10 minutes to collect cells, and the cells were suspended into 100 mL of a 50 mM phosphate buffer solution (pH 6.0). Next, a 100 mg/mL solution of the substrate 11107B substance in dimethyl sulfoxide was prepared, and each 0.5 mL of the solution was added. After the addition, it was shaken at 28° C. for 24 hours to carry out conversion. After the completion of the reaction, the reaction mixtures were collected and separated into the supernatant and mycelium cake by centrifugation at 5000 rpm for 20 minutes. The supernatant was extracted with 1 L of ethyl acetate. The mycelium cake was extracted with 500 mL of methanol and then filtrated to give a methanol extract. The methanol extract was evaporated to remove methanol and extracted with 1 L of ethyl acetate. Each of the ethyl acetate layers was washed with water, dried over anhydrous sodium sulfate, and the combined layers were evaporated to give 937 mg of a crude active fraction. The crude active fraction was subjected to silica gel column chromatography (Kiesel gel 60, 50 g) and eluted with 1200 mL of a mixture of ethyl acetate and n-hexane (90:10; v/v) to give 234 mg of an active fraction. The resulting active fraction was subjected to preparative high performance liquid chromatography (HPLC) under the following preparative HPLC condition (C), and the resulting eluate was analyzed by HPLC under the following analytic HPLC condition (c). The solvent was removed from the fraction containing the 11107D substance thus obtained, to give 80 mg of the 11107D substance.
Preparative HPLC Condition (C)
Each of cultures of A-1545 strain (FERM P-18944) (100 mL/500 mL Erlenmeyer flask, 10 flasks) obtained by a similar method as described for Referential Example 9 was subjected to centrifugation at 3000 rpm for 10 minutes to collect cells, and the cells were suspended into 100 mL of a 50 mM phosphate buffer solution (pH 6.0). Next, a 100 mg/mL solution of the substrate 11107B in dimethyl sulfoxide was prepared, and each 1 mL of the solution was added. After the addition, it was shaken at 28° C. for 24 hours to carry out conversion. After the completion of the reaction, the reaction mixtures were collected and separated into the supernatant and mycelium cake by centrifugation at 5000 rpm for 20 minutes. The supernatant was extracted with 1 L of ethyl acetate. The mycelium cake was extracted with 500 mL of acetone, and then filtrated to give an acetone extract. The acetone extract was evaporated to remove acetone, and extracted with 1 L of ethyl acetate. Each of the ethyl acetate layers was washed with water, dried and dehydrated over anhydrous sodium sulfate, and the combined layers were evaporated to give 945 mg of a crude active fraction. The crude active fraction was subjected to silica gel column chromatography (Kiesel gel 60, 50 g), eluted with 100 mL of a mixture of ethyl acetate and n-hexane (50:50; v/v), 200 mL of a mixture of ethyl acetate and n-hexane (75:25; v/v), and 600 mL of a mixture of ethyl acetate and n-hexane (90:10; v/v), to give 463 mg of an active fraction. The obtained active fraction was subjected to preparative high performance liquid chromatography (HPLC) under the preparative HPLC condition (C) described in Example 4, the resulting eluate was analyzed by HPLC under the analytic HPLC condition described in Example 4. The solvent was removed from the fraction containing 11107D substance thus obtained, to give 304 mg of 11107D substance.
