Description Method for stabilizing macrolide compounds Technical Field The present invention relates to a method for stabilizing 12-membered ring macrolide compounds having an antitumor activity, and to a method for producing the compounds. Prior Art A 12-membered ring macrolide compound expressed by the formula (1) : (Figure Removed) (hereinafter referred to as macrolide compound 11107B) is an antitumor compound discovered in a cultured product of a Streptomyces sp. Mer-11107 strain, and furthermore chemical synthesis using this compound and analogs thereof as the raw material has been found to yield a macrolide compound having even better antitumor activity (see W002/060890). However, these macrolide compounds are not sufficiently stable, particularly in an aqueous solution, and there has been a need for some way to improve their stability and produce them more efficiently. Meanwhile, cyclodextrins are non-reducing sugars in which a glucose molecule is bonded in a ring by -l,4 bonds, and , ß- and γ-cyclodextrin, in which there are six, seven and eight glucose residues, respectively, are commonly known. Cyclodextrins have the property of forming complex with other compounds in their central cavity, and "are used for stabilizing or solubilizing the included compound, preventing its oxidation, rendering it nonvolatile, and so forth. Also, cyclodextrins are known to have the effect of improving productivity when added to a culture medium in the fermentation of lankacidin antibiotics (see JP-A 58-177949 and JP-A 58-179496). However, cyclodextrins will not include just any compound, and even if they include a compound, they will not necessarily contribute to stabilization and so forth. Similarly, they do not improve productivity in the fermentation of just any compound.

There are no particular restrictions on the actinomycetes having an ability of producing the macrolide compound, as long as they are indeed actinomycetes having an ability of producing a macrolide compound, but examples include actinomycetes belong to the genus Streptomyces, and particularly Streptomyces sp. Mer-11107 isolated from soil, or Streptomyces sp. A-1532, Streptomyces sp. A-1533, Streptomyces sp. A-1534, etc., which are variants of Mer- 11107. It is to be noted that the Streptmyces sp.

Fermentation method of producing microorganism The macrolide compound according to the present invention can be produced by inoculating the strain on a nutrition source medium and fermenting aerobically. The fermentation method of the above-mentioned microorganism is according to the general fermentation method of microorganism, except that a cyclodextrin is made to be present. 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 to the genus Streptomyces, therefore all of various synthetic, a semisynthetic 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 meal, 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. In the present invention, a cyclodextrin is made to be present in the above-mentioned culture broth. The concentration of the cyclodextrin in the culture broth may be suitably selected within a range that will not impair the growth of the microorganism being used, and is preferably from 0.1 to 100 mg/mL, with 10 to 30 mg/mL being even better. There are no particular restrictions on the point when the cyclodextrin is added, which may be either before or after the culture medium is inoculated with the microbes that produce the macrolide compound, but it is preferable to add the cyclodextrin to the medium before the macrolide compound-producing microbes produce the targeted substance. Examples of the cyclodextrin used in the producing method of the present invention are those listed in the section dealing with the method for stabilizing a macrolide compound above, but it is preferable to select from the group comprising p-cyclodextrin, y-cyclodextrin, partially methylated p-cyclodextrin, dimethyl-p-cyclodextrin, glucosyl-p-cyclodextrin, and hydroxypropyl-p-cyclodextrin. These cyclodextrins can be used singly or in combinations of two or more. When foaming is occurred during fermentation, any of various defoaming agents can be added to the medium as necessary. In adding a defoaming agent, the concentration must be set low enough so that the agent will not have an inordinately adverse effect on the production of the targeted substance, and using the agent in a concentration of 0.3% or less is preferable, for example. The conditions of fermentation can be appropriately selected within a range over which this microbial strain will grow well and can produce the above-mentioned substance. For instance, the pH of a medium is about 5 to 9, andpreferably nearby neutral in general. The temperature of fermentation is usually kept between 20 and 40°C, and preferably between 28 and 35°C. The fermentation period is about 2 to 8 days, and usually about 3 to 6 days. The above fermentation conditions can be suitably changed in accordance with the kind and properties of microorganism used, external conditions and the like, and it is needless to say that the optimum conditions can be selected. The macrolide compound that accumulates in the culture broth can be recovered by an ordinary separation process that is suited to the properties thereof, such as solvent extraction or the use of an adsorbent resin. 3. Purification of macrolide compound Any separation and purification methods which are commonly used for isolating microbial metabolites from their culture broth can be utilized to collect the macrolide compound from the culture broth after fermentation. It is possible to employ any other known method, for example, (1) organic solvent extraction using methanol, ethanol, butanol, ethyl acetate, butyl acetate, toluene, chloroform or the like, (2) an adsorption and desorption treatment using a hydrophobic adsorbent resin such as Diaion, HP-20 or the like, (3) various kinds of ion exchange chromatography, (4) gel filtration chromatography using Sephadex LH-20 or the like, (5) activated carbon, (6) adsorption chromatography using silica gel or the like, or an adsorption and desorption treatment by thin layer chromatography or (7) high performance liquid chromatography using a reverse phase column or the like. The purification methods are not limited to those listed here. A macrolide compound can be isolated and refined by using these methods alone, or by combining them in any order desired, or by employing them repeatedly. The stabilization method of the present invention allows a macrolide compound to be stabilized in the solid phase or in solution. Also, the producing method of the present invention allows a macrolide compound to be produced efficiently. Brief description of Drawing Fig. 1 shows the results of plotting l/(k0-k0bs) versus the inverse of the p-cyclodextrin concentration, as obtained in Example 2. Examples The present invention will now be described in specific terms by giving Examples, but the present invention is not limited in any way by these examples. In the following description, all concentrations given are in volume percent unless otherwise specified. Example 1 Effects of various cyclodextrins on stabilization of macrolide compound The macrolide compound 11107B (hereinafter sometimes abbreviated as 11107B) and various cyclodextrins were dissolved in concentrations of 0.1 mg/mL and 10 mg/mL, respectively, in Dulbecco's PBS (-). The 11107B solution and cyclodextrin solution were mixed in equal volumes, and incubation was immediately begun in at thermostatic incubator at 25°C. The solution was sampled at the start (0 hour) and after 24 and 48 hours had elapsed, the samples were analyzed by high performance liquid chromatography (HPLC) under the following analysis conditions (A), and the purity of the 11107B was calculated from the following equation using the chromatogram thus obtained. These results are given in Table 1. It can be seen from these results that of the cyclodextrins examined, pcyclodextrin has the best stabilizing effect. a-CD: a-cyclodextrin P~CD: p-cyclodextrin y-CD: y-cyclodextrin HP-a-CD: hydroxypropyl-a-cyclodextrin HP-p-CD: hydroxypropyl-p-cyclodextrin HP-y-CD: hydroxypropyl-y-cyclodextrin Column: L-column, 4.6 x 150 mm, Chemicals Evaluation and Research Institute Column temperature: 35°C Flow rate: 1 mL/min Detection wavelength: 241 nm Mobile phase A: 0.1% (v/v) formic acid • 10% (v/v) acetonitrile Mobile phase B: 0.1% (v/v) formic acid • 90% (v/v) acetonitrile Gradient program: B=10% (start) -» B=40% (15 minutes) -> B=100% (20 minutes) -> B=10% (20.01 minutes) -> B=10% (23 minutes, stop) 11107B purity (%)=[peak surface area value of 11107B/(sum of peak surface area value of 11107B+peak surface area value of impurities and decomposition products)]xlOO Table 1 (Table Removed) Example 2 Calculation of stabilization coefficients of macrolide compound 11107B and p-cyclodextrin (cyclodextrin will hereinafter be abbreviated as CD) The macrolide compound 11107B was dissolved in Dulbecco's PBS (-) in a concentration of 0.1 mg/mL, and P-CD in concentrations of 10, 3, 1, and 0.3 mg/mL. The 11107B solution and p-CD solution were mixed in equal volumes, and incubation was immediately begun in a 40°C thermostatic incubator. The solution was sampled at the start (0 hour) and after I, 2, 4 and 6 hours had elapsed, the samples were analyzed by HPLC under the analysis conditions (A) of Example 1, and the concentration of the 11107B was calculated. Since the plot of the 11107B concentration versus elapsed time was substantially linear, it was concluded that decomposition was occurring in pseudo first-order reaction, and the apparent decomposition rate constant k0bs was calculated from the slope thereof. k0bs was termed k0 when no p-CD was prevent. According to a report by Ma et al. (J. Pharm. Sci. (2000), 8J3 (2), 275- 287), l/(k0 - k0bs) was plotted against the inverse of the P-CD concentration, kc, which is k0bs when a large excess of P-CD was present, was calculated from an intercept thereof, and the stabilization constant Kc was calculated from the slope. The results are given in Table 2 and Fig. 1. These results show that ko and kc were estimated to be 0.152 hr'1 and 0.004 hr"1, respectively, and that the decomposition rate of included 11107B was l/30th or less than that of 11107B that was not included. Also, since Kc was estimated to be 1500 or more, this shows that, in the solution of 11107B with equal molar ratio of P~CD, almost all of the 11107B include in p-CD.

The 11107B solution and P~CD solution were mixed in equal volumes, and incubation was immediately begun in thermostatic incubator at 25°C. The solution was sampled at the start (0 hour) and after 24, 48 and 120 hours had elapsed, and the samples were analyzed by HPLC under the following analysis conditions (B). The purity of the 11107B was calculated from the equation in Example 1 using the resulting chromatogram.
