Abstract

PROBLEM TO BE SOLVED: To obtain a new antineoplastic material manifesting antineoplastic effects even in various tumors on which an ordinary antineoplastic agents can not manifest their effects. SOLUTION: This material is a compound expressed in formula (R<1> is OH or a hydrazino; R<2> is H or methyl). This compound is obtained by aerobic culture of a microorganism or its variant, such as streptomyces sp A4230, in a culturing medium like yeast, malt agar and collecting. The culturing condition is at 22-37 deg.C (preferably 26-37 deg.C), at 4-8pH of and for 48-192 hours (preferably 72-144 hours).

2. Description of the Related Art In the field of cancer chemotherapy, many compounds have already been put into practical use as pharmaceuticals. However, its effect on various types of tumors is not always sufficient, and its clinical applicability is complicated as the phenomenon of resistance of tumor cells to these drugs is clinically revealed [47] Article of the General Meeting of the Japanese Cancer Society, 12
Pp. 15-15 (1988) etc.]. Under such circumstances, the development of new antitumor substances is always required in the field of cancer treatment.

From the above-mentioned mycological characteristics, the A42303 strain is considered to belong to the genus Streptomyces of actinomycete. Therefore, the A42303 strain is treated with Streptomyces sp.
A42303 (Streptomyces sp.
A42303). The strain has been deposited at the Institute of Biotechnology, Institute of Industrial Science and Technology, Ministry of International Trade and Industry, and the deposit number is FERM P-14706.
The mutant strains of the microorganisms that produce the antitumor substances BE-42303A and B used in the present invention are treated by irradiation with, for example, X-rays or ultraviolet rays, such as nitrogen mustard, azaserine, nitrous acid, 2-aminopurine or N.
-Methyl-N'-nitro-N-nitrosoguanidine
Treatment with a mutagen such as (NTG), phage contact,
It is a microorganism obtained by mutating BE-42303A and B-producing bacteria by a commonly used bacterial species conversion treatment method such as transformation, transduction or conjugation. BE-42303 of the present invention
In producing A and B, a culture strain containing BE-42303A and B is obtained by inoculating a nutrient source-containing medium with a strain producing BE-42303A and B and allowing the strain to grow aerobically. As the nutrient source, those known as the 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 soybean flour,
Corn stay liquor, meat extract, yeast extract, dry 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. Other than these, any of those that are utilized by the producing bacterium and useful for the production of BE-42303A and B, 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. The culture temperature is appropriately 22 to 37 ° C, preferably 26 to 37 ° C. The preferable medium pH is in the range of 4 to 8, and the culture time is 48 hours to 1
92 hours, preferably 72 hours to 144 hours. BE-42303A and B of interest from culture
In order to collect, the separation means usually used for collecting from the metabolite produced by the microorganism is appropriately used. BE-
Since 42303A and 42303A are present in the culture filtrate and the bacterial cells, the usual separation means from the culture filtrate or the bacterial cells, such as the solvent extraction method, the ion exchange resin method or the adsorption or partition chromatography method and the gel filtration method, is used alone. Alternatively, the purification can be carried out in combination. Preferred examples of separation and purification include the following methods. First, the culture solution is filtered to obtain cells. The obtained bacterial cells are extracted with an organic solvent such as methanol or acetone. The obtained crude extract was partitioned with water / 2-butanone, and the extract obtained after distilling off 2-butanone was subjected to silica gel chromatography (eluted with chloroform / methanol) to powder BE-42303A and B. Alternatively, it can be obtained as a solid. The hydroxy group of the compound represented by the formula [1] of the present invention in which R 1 is a hydroxy group can be converted to a hydrazino group by a method usually used in the field of chemistry. BE-42303A, BE-42303C, B
E-42303B can be converted into BE-42303D, respectively. Compound of the invention BE-4230
