  Microbial hydrolysis of 7-xylosyl-10-deacetyltaxol to 10-deacetyltaxol

  摘要：

  Enterobacter sp. CGMCC 2487, a bacterial strain isolated from the soil around a Taxus cuspidata Sieb. et Zucc. plant, was able to remove the xylosyl group from 7-xylosyltaxanes. The xylosidase of this strain was an inducible enzyme. In the bioconversion of 7-xylosyl-10-deacetyltaxol (7-XDT) to 10-deacetyltaxol (10-DT), for the purpose of enhancing the conversion efficiency, the effects of NH4+, oat xylan, temperature, pH value, cell density and substrate concentration on the bioconversion have been systematically investigated. 3.0 mM NH4+, 0.6% oat xylan in the media could enhance the yield of 10-DT; the optimum biocatalytic temperature was 26 degrees C and optimum pH value was 6.0. The highest conversion rate and yield of 10-DT from 7-XDT reached 92% and 764 mg/L, respectively. In addition, the biocatalytic capacity of the cell cultures remained 66.1% after continuous three batches. These results indicate that converting 7-XDT to 10-DT, a useful intermediate for the semisynthesis of paclitaxel or other taxane-based anticancer drugs by a novel bacterial strain, Enterobacter sp. CGMCC 2487, would be an alternative for the practical application in the future. (C) 2010 Elsevier B.V. All rights reserved.

  The present invention discloses a process for the conversion of a mixture of taxol analogues 7-xylosyl-10-deacetylbaccatin taxols of the formula 2 where R is C6H5, CH3C═CHCH3 or C5H11 into 10-deacetylbaccatin III of the formula 1 by dissolving the taxol analogue of formula 2 in a polar solvent, reacting the resultant solution with a base at a temperature of 20-50° C. for a time period in the range of 20-40 hours, and isolating 7-xyloxyl-10-deacetylbaccatin III, dissolving the 7-xylosyl-10-deacetylbaccatin III in a polar solvent, reacting the resultant solution with a periodate at 20-40° C. for a time period in the range of 20-40 hours to cleave the diol system of the xyloside into dialdehyde, treating the generated dialdehyde in an organic acid medium with salts of amine at 0-40° C. for 12-18 hours and isolating 10-deacetylbaccatin III of formula 1.
