    • 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.
    • 本发明提供了紫杉醇,浆果赤霉素III和其他紫杉酚样化合物或紫杉烷可以以非常高的产率从所有已知的红豆杉属物种例如短叶菊,加拿大,东北大西洋荚果,球果,球果,弗罗里达,沃利希纳,媒介 和中华猕猴桃。 已经发现培养条件(即培养基组成和操作模式)的特定修饰以增强来自所有种类红豆杉细胞培养物的各种紫杉烷的产量。 特别优选的增强剂包括银离子或络合物,茉莉酸(尤其是甲酯),生长素相关的生长调节剂和苯丙烷途径抑制剂,例如3,4-亚甲二氧基-6-硝基肉桂酸。 这些增强剂可以单独使用或彼此组合使用或其他产量增强条件。 虽然通过使用一种或多种这些条件,特别提高了来自T.chinensis植物细胞培养物的紫杉烷的产率,但是已发现所有红豆杉属物种的紫杉烷产率都受益于​​使用这些条件。

    • PURPOSE: Provided are 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. CONSTITUTION: A method for producing taxanes in high yields in cell culture of a Taxus species comprises: cultivating in suspension culture, in one or more nutrient media under growth and product formation conditions, cells of a Taxus species derived from callus or suspension cultures, and recovering one or more taxanes from said cells or said medium of said cell culture, or both, wherein the one or more nutrient media contain an inhibitor of phenylpropanoid metabolism. The inhibitor of phenylpropanoid metabolism is selected from 3,4-methylenedioxy-6-nitrocinnamic acid, 3,4-methylenedioxycinnamic acid,, 3-£3,4-methylenedioxyphenyl| propionic acid, 3,4-methylenedioxyphenylacetic acid, 4-Fluoro-L-Phenylalanine, 4-Hydroxyphenylpyruvic acid, 4-Fluoro-DL-Tyrosine, Trans 3,4-Dimethoxycinnamic acid, phenylpropiolic acid, L-2-Hydroxy-3-Phenylpropionic acid, 2-hydroxy-4,6-dimethoxybenzoic acid, SKF-525A, vinylimidazole, ammonium oxalate, sinapic acid, and 1 -aminobenzotriazole.
