Preparation of C-13 hydroxyl-bearing taxanes using nocardioides or a hydrolase isolated therefrom

摘要

Compounds useful as intermediates in the preparation of taxanes such as taxol are prepared by contacting one or more C-13 acyloxy-bearing taxanes with an enzyme or microorganism capable of hydrolyzing said acyloxy groups to hydroxyl groups. In a preferred embodiment the microorganism is Nocardioides albus ATCC55424, Nocardioides albus ATCC55425 or Nocardioides luteus ATCC55426 or the hydrolase enzyme is isolated from the microorganisms.
