Abstract

PROBLEM TO BE SOLVED: To obtain the subject new compounds, comprising an antitumor substance prepared by culturing a microorganism such as Streptomyces sp. or its mutant, capable of inhibiting the proliferation of tumor cells and manifesting antitumor actions and useful as a therapeutic agent, etc., for cancer. SOLUTION: The new antitumor substances BE-43537s are represented by the formula [R is (CH2 )10 CH(CH3 )2 , (CH2 )12 CH3 , (CH2 )10 CH(CH3 )CH2 CH3 , (CH2 )11 CH(CH3 )2 , (CH2 )13 CH3 , (CH2 )12 CH(CH3 ) or (CH2 )14 (CH3 )] and capable of inhibiting the proliferation of tumorous cells and manifesting antitumor actions and useful as a therapeutic agent for cancer in the medicinal field. The antitumor substances are obtained by culturing a microorganism having the ability to produce the compounds represented by the formula [e.g. Streptomyces sp. A43547 (FERM P-14444)] or its mutant and collecting the resultant product from the cultured product.

[Table 3] 6. Cell wall composition LL diaminopimelic acid and glycine were detected. From the above mycological properties, the A43547 strain is considered to belong to the genus Streptomyces. Therefore, A43
547 strains of Streptomyces sp. A43547
(Streptomyces sp. A4354
7). The strain has been deposited with the Research Institute of Biotechnology and Industrial Technology, Ministry of International Trade and Industry of Japan, and the deposit number is FERM P-14444. The mutant strain of the microorganism producing the antineoplastic substances BE-43547 used in the present invention may be, for example, irradiated with X-rays or ultraviolet rays, for example, nitrogen mustard, azaserine, nitrite, 2-aminopurine or N-methyl. BE by a commonly used bacterial species conversion treatment method such as treatment with a mutagen such as -N'-nitro-N-nitrosoguanidine (NTG), phage contact, transformation, transduction or conjugation.
It is a microorganism obtained by mutating a -43547-producing bacterium. In producing BE-43547s of the present invention, BE-4
A culture containing BE-43547 can be obtained by inoculating a 3547-producing strain into a nutrient-containing medium and growing it aerobically. As a nutrient source, a known nutrient source for actinomycetes can be used. For example, as a carbon source, commercially available glucose, maltose, starch, sucrose, molasses, dextrin, or the like is used alone or as a mixture. As the nitrogen source, commercially available soy flour,
Corn steep liquor, gluten meal, meat extract,
Yeast extract, dried yeast, cottonseed flour, peptone, wheat germ,
Fish meal, meat meal, defatted rice bran, defatted meat-and-bone meal, inorganic ammonium salts or sodium nitrate are used alone or as a mixture. As the inorganic salt, commercially available calcium carbonate, sodium chloride, potassium chloride, magnesium sulfate, sodium bromide, sodium borate or various phosphates can be used. In addition, if necessary, trace amounts of heavy metal salts such as iron, manganese, zinc, cobalt, and molybdic acid can be added. In the case of severe foaming, for example, vegetable oils such as soybean oil or linseed oil, higher alcohols such as octadecanol, various silicon compounds, and the like may be appropriately added as antifoaming agents. In addition to these, BE-
Any of those useful for the production of 43547, such as 3- (N-morpholino) propanesulfonic acid or sodium borate, can be used. The culturing method may be the same as the method for producing a general microbial metabolite, and may be a solid culture or a liquid culture. In the case of liquid culture, any of static culture, stirring culture, shaking culture, and aeration culture may be performed, but shaking culture or deep aeration stirring culture is particularly desirable. Culture temperature is 15-41 ° C
Is suitable, but preferably 22 ° C to 35 ° C. The preferable pH of the medium is in the range of 4 to 8, and the culture time is 12 hours.
0 hours to 216 hours, preferably 144 hours to 192 hours. In order to collect the desired BE-43547 from the culture, a separation means usually used for collecting from metabolites produced by microorganisms can be appropriately used. Since BE-43547 is present in the cells, it can be separated from the cells by a conventional separation means such as a solvent extraction method, an ion exchange resin method or an adsorption or partition chromatography method and a gel filtration method alone or in combination. Can be purified. Preferred examples of separation and purification include the following methods. First, the culture solution is filtered to obtain cells. The obtained cells are extracted using an organic solvent such as methanol or acetone. The obtained crude extract was partitioned with a water-ethyl acetate system, and the residue obtained after evaporating the ethyl acetate layer was subjected to silica gel chromatography (eluted with chloroform / methanol).
E-43547 can be obtained as a powder or a solid. The compounds BE-43547 of the present invention inhibit the growth of tumor cells and exhibit an antitumor effect. However, various forms can be selected as the administration form when the compound of the present invention is used as an antitumor agent. And oral preparations such as capsules, powders, granules or liquids, or sterile liquid parenteral preparations such as solutions or suspensions.
Solid preparations can be produced as they are in the form of tablets, capsules, granules or powders, or they can be produced using appropriate additives. Such additives include, for example, sugars such as lactose or glucose, for example, starches such as corn, wheat or rice,
For example, fatty acids such as stearic acid; inorganic salts such as magnesium aluminate metasilicate or anhydrous calcium phosphate; synthetic polymers such as polyvinylpyrrolidone or polyalkylene glycol; fatty acid salts such as calcium stearate or magnesium stearate; Alcohols such as benzyl alcohol, for example, synthetic cellulose derivatives such as methylcellulose, carboxymethylcellulose, ethylcellulose and hydroxypropylmethylcellulose, and other commonly used additives such as water, gelatin, talc, vegetable oil, and gum arabic can be mentioned. Solid preparations such as tablets, capsules, granules and powders generally contain 0.1 to 100% by weight,
It preferably contains from 5 to 100% by weight of active ingredient. Liquid preparations use suitable additives usually used in liquid preparations such as water, alcohols or vegetable-derived oils such as soybean oil, peanut oil or sesame oil, and are used in the form of suspensions, syrups or injections. Manufactured as Particularly suitable solvents for parenteral administration by intramuscular injection, intravenous injection or subcutaneous injection include, for example, distilled water for injection, lidocaine hydrochloride aqueous solution (for intramuscular injection), physiological saline, glucose aqueous solution, ethanol, Liquid for intravenous injection (for example, aqueous solution of citric acid and sodium citrate) or electrolyte solution (for intravenous drip and intravenous injection)
Or a mixed solution thereof. These injections may be dissolved in advance, or may be in the form of powder or dissolved in a suitable additive before use. These injections are usually 0.1 to 10% by weight,
It preferably contains 1 to 5% by weight of active ingredient. Liquid preparations such as suspensions or syrups for oral administration are 0.5 to 10%.
