title: Semisynthesis and biological evaluation of a novel D-seco docetaxel analogue.
abstract: [reaction: see text] A 4-methyl-5-oxo docetaxel analogue has been prepared starting from 10-deacetylbaccatin III. This new D-seco docetaxel analogue is slightly less potent than docetaxel at microtubule stabilization in vitro and has about 1/1000th the cytotoxicity of docetaxel. The lack of improved activity for this compound compared to other D-modified taxoids confirms that a C-5 oxygen atom is not required for biological activity.
