Method of producing taxol and taxones from embryo plant culture of taxus genus

Номер: RU2120740C1

FIELD: biotechnology. SUBSTANCE: method involves using zygote embryos from yew seeds of species Taxus cuspidata as explants. Callus tissue is cultured up to formation of somatic embryos and then to embryogenic callus preparing. The latter is passaged in liquid nutrient medium and cultured on Hamburg medium mB 5 containing 2-4 ppm 2,4-D (2,4-dichlorophenoxyacetic acid) for cellular mass increase. Then culturing is continued on Murasige-Skoog Ms or Hamburg mB 5 medium containing 1-2 ppm NAA (α--naphthylacetic acid) that stimulates the yield of the end product. The end product is isolated by extraction from somatic embryos at stage of callus culturing or from embryogenic callus at stage of disinfected embryos culturing. The end product can be isolated from cellular suspension mass and cultural fluid. EFFECT: increased yield of taxol and taxones. 7 cl, 7 dwg, 3 tbl, 11 ex ОтДОСКсС ПЧ ГЭ РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (19) ВИ "” 2120 740 ' 13) СЛ ОМК АОлН 4/00, С 12 М 5/00 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 95109640/13, 06.07.1994 (30) Приоритет: 06.07.1993 КК 1993-12641 20.06.1994 КВ 1994-13914 (46) Дата публикации: 27.10.1998 (56) Ссылки: МО 92/13961 АЛ, 20.08.92.

Enhanced production of taxanes by cell cultures of taxus species

Номер: EP1538214A1
Принадлежит: Phyton Inc

This invention provides methods whereby taxol, baccatin III, and other taxol-like compounds, or taxanes, can be produced in very high yield from all known Taxus species, e.g. brevifolia, canadensis, cuspidata, baccata, globosa, floridana, wallichiana, media and chinensis . Particular modifications of culture conditions (i.e. media composition and operating modes) have been discovered to enhance the yield of various taxanes from cell culture of all species of Taxus. Particularly preferred enhancement agents include silver ion or complex, jasmonic acid (especially the methyl ester), auxin-related growth regulators, and inhibitors of the phenylpropanoid pathway, such as 3,4-methylenedioxy-6-nitrocinnamic acid. These enhancement agents may be used alone or in combination with one another or other yield-enhancing conditions. While the yield of taxanes from plant cell culture of T. chinensis is particularly enhanced by use of one or more of these conditions, yield of taxanes for all Taxus species has been found to benefit from use of these conditions.
