ABSTRACT
Administering Taxus suspension cells with labeled 5alpha-hydroxytaxadiene and 5alpha,10beta-dihydroxytaxadiene, and the corresponding 5alpha-acetate esters, demonstrated that acetylation at C5 of the monool precursor promotes the formation of 14beta-hydroxy taxoids, such as taxuyunnanine C, at the expense of 13alpha-hydroxy taxoids, including Taxol and its congeners, but that the major bifurcation in taxoid biosynthesis, toward 13alpha- or 14beta-hydroxy taxoids, occurs after 10beta-hydroxylation of the taxane core.
