Abstract

See full text

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.
