Definitions
- the present invention relates to a novel antitumor active compound NSC-LSC1 belonging to the class of taxol (Tax01) and a method for producing the same.
- the compound has low toxicity like taxol and has strong antitumor activity.
- Taxol a taxane-based diterpene
- Taxaceae a taxane-based diterpene
- This taxol has attracted attention as a compound having low toxicity and stronger antitumor activity against human tumors.
- This taxol has been subjected to clinical trials as an antitumor agent as extracted from the bark of the Chinese yew tree (Taxus brevifolia ⁇ .) Belonging to the genus Taxus (Taxus) of the Taxaceae family (for example, David GIKingston, Pharmac. Ther. Vol.
- an object of the present invention is to develop a novel antitumor active compound which is expected to have low toxicity and specific antitumor activity against human tumors, and to realize a stable supply thereof. To provide a manufacturing method. Disclosure of the invention
- the present inventors have also focused on antitumor active compounds contained in plants belonging to the Taxiaceae family (Taxaceae) and have conducted intensive research. We have succeeded in isolating a novel compound that shows tumor activity but has a clearly different conformation from taxol. In addition, it was confirmed that this compound can be efficiently produced from calli that are easily induced and proliferated by tissue culture using the endosperm of the Chinese lantern. Thus, the novel compound of the present invention can be supplied stably.
- the compound of the present invention is a structural isomer having a bonding mode of at least the 2′-hydroxyl group different from that of taxol.
- NSC-LSC1 antitumor active compound NSC-LSC-1
- the present invention also provides a method for producing NSC-LSC1
- the present invention also provides a method comprising culturing a callus derived from the endosperm of Tigeria oleracea and collecting the NSC-LSC1 from the culture.
- the NSC-LSC1 provided by the present invention has a strong growth inhibitory activity against mouse and human transplanted cancer cells, but has low toxicity to such animals, so that it is used in the field of cancer chemotherapy. Is a promising compound expected.
- NSC-LSC1 shows extremely strong antitumor activity against human tumor cells.
- the NSc-LSc1 of the present invention can be advantageously produced by the method of the present invention described below.
- a method for producing a compound NSC-LSC1 by culturing a tissue derived from Taxus brevifolia NUTT.
- step b) a step of inducing callus by culturing the tissue obtained in step a) in a nutrient medium suitable for inducing karyu,
- step c) culturing the callus obtained in step b) in a nutrient medium suitable for callus growth; and d) a step of collecting NSC—LSC 1 from the culture obtained in step c),
- a method for producing LSC1 comprising: Preparation of tissue from live endosperm is performed by sterilizing seeds collected from the Chinese cabbage tree with 0% ethanol and sodium hypochlorite aqueous solution, and then sterilizing the material. And then inoculating the endosperm and inoculating it in a medium suitable for inducing the following callus, which has been solidified with agar or gel light (gellan gum, Merck & Co. Inc.).
- the living tissue obtained in the above-described step is cultured in a nutrient medium suitable for inducing callus, and the induced callus is cultured in a nutrient medium suitable for its growth.
- the basic components used in such a nutrient medium are water; inorganic elements such as nitrogen (ammonium salt, nitrate), phosphorus, calcium, calcium, magnesium, and iodine; sugars, such as Trace inorganic elements; organic substances such as vitamins and amino acids; natural substances such as coconut milk; and, in some cases, agar, gel light ®, alginic acid and agarose.
- compositions used as the basic medium of the present invention include Schenk & Hildebrandt medium (hereinafter referred to as “SH medium”), Murashige Skoog ge & Skoog) medium (hereinafter referred to as “MS medium”), Gamborg's B5 medium, white medium, and niche
- auxin for example, 1-naphthaleneacetic acid (hereinafter referred to as “NAA”), indole— 3—acetic acid (hereinafter referred to as “IAA”), indole— 3—butyric acid (hereinafter referred to as “IBA j”) and 2,4-dichlorophenoxyacetic acid (hereinafter referred to as “2,4—D”); cy tokinin, eg, benzyladenine ( hereinafter, Ru 1 BA j and referred 3), kinetin, zeatin and 6 - fur fury - laminopurine such ⁇ gibberel 1 in (hereinafter, referred to as r GA ”)
- GA and the like GA 3, but is suitably added.
- a nutrient medium suitable for inducing callus a medium obtained by adding auxin, cytokinin and gibberellins to the above-mentioned basic medium, more specifically, an SH medium as the basic medium, and the BA as rhino Tokainin and Jibe Lelie medium and the GA 3 was added as a down such, or as to N AA auxin and medium with kinetin is preferred as rhino Tokaj Nin.
- a medium suitable for callus growth a medium obtained by adding cytokinin and auxin to the above-mentioned basic medium, more specifically, SH medium as basic medium, kinetin as cytokinin, and auxin
- a medium supplemented with NAA or 2,4-D is preferable.
- Such a medium is adjusted to pH 5 to 7, preferably pH 5.5 to 6.0, using a suitable acid or alkali.
- the above cultivation using these media is 15 to 25, respectively. It can be carried out at a temperature within the range described above, with or without light irradiation.
- cultivation for the purpose of callus growth is preferably performed using a liquid medium in a shaking incubator.
- Extraction of NSC-LSC1 from the culture thus obtained can be performed according to a known method for isolating and purifying various alloids from tissue culture.
- the term “culture” is used to mean cultured cells and cell clumps (callus), and their suspensions (especially when a liquid medium is used).
- the extraction of NSC-LSC1 from such cultures is generally done by separating, drying and milling the calli.
- the powder obtained is then extracted with a suitable organic solvent and optionally extracted. After washing the organic phase with an aqueous solution and drying, the solvent can be distilled off.
- the extracted NSC—LSC1 can be purified by various methods such as mouth chromatography, recrystallization, etc., if necessary.
- Organic solvents that can be used for the extraction include chlorinated hydrocarbons such as methylene chloride and dichloroethane, and alcohols such as methanol, ethanol and isopropyl alcohol. , And mixtures thereof.
- the endosperm prepared in this manner was added to both a plant hormone, benzylazidenine (BA), and GA3, a type of gibberellin, to adjust the pH to 5.8 in a SH medium (0.25% A solid medium was prepared by adding gel light).
- the concentrations of BA and GA3 added to the medium were 1 or 5 or 10 ragZ 1 and 0 or 1 or 10 or 100 mg, respectively. When they were cultured at 20 ° C or 25 ° C under light (16 hours daylength), virulas were induced after about 2 months.
- the callus derived from the endosperm in this manner was transferred to an SH medium (liquid medium) in which naphthaleneacetic acid (NAA) and kinetin were added and the pH was adjusted to 5.8.
- the concentrations of NAA and kinetin added to the medium were 5 mgZ1 and 0 or 0.1 or 0.5 mg / l, respectively.
- the volume of the medium was 40 ml per 100 ml Erlenmeyer flask, and the cells were shake-cultured at 100 rpm using a shaking incubator. The culture temperature was 20 degrees and the light conditions were dark.
- the calli grown in this manner were collected and air-dried. After 30 g of dry callus was sufficiently homogenized using a mortar, 500 ml of a 1: 1 mixture of methanol and methylene chloride was added, and the mixture was added at room temperature using a Sakaguchi flask. Shaking and extraction were performed for 16 hours. After repeating this operation three times, the mixture was concentrated under reduced pressure to obtain 1.03 g of a brown substance. This was partitioned with 500 ml of a 1: 1 mixture of methylene chloride and water, and a layer of methylene chloride was collected. This operation was repeated several times, and the solution was concentrated under reduced pressure again to obtain 53 O mg of a brown substance.
- the NSC-LSC1 of the present invention has low toxicity and strong antitumor activity and can supply NSC-LSC1 stably by tissue culture using Taxus brevifolia embryo, the present invention can be used in the pharmaceutical manufacturing industry. .
