Combination of Paclitaxel and Nitric Oxide as a Novel Treatment for the Reduction of Restenosis

The combination of a nitric oxide (NO) donor and a paclitaxel-NO donor conjugate coated on a vascular stent was tested in a rabbit iliac artery model of stenosis as a potential therapy for restenosis. Paclitaxel was conjugated with a NO donor at the 7-pos

Synthesis and evaluation of some water-soluble prodrugs and derivatives of taxol with antitumor activity

The synthesis and evaluation of some 2'- and 7-amino acid derivatives of taxol (1) are reported. Reaction of taxol with N-protected amino acids gave 2'-N-protected amino acid esters of taxol. However, deprotection of the amino group and subsequent isolati

Modified Taxols. 2. Oxidation Products of Taxol

Oxidation of taxol (1) or substituted taxols with Jones' reagent under appropriate conditions yielded 7-oxotaxol (6), 2',7'-dioxotaxol (9), or 2'-oxo-7-acetyltaxol (12).Treatment of 7-oxotaxol with DBU or silica gel yielded a D-secotaxol derivative 14.Hydrogenation of the 2'-acetate derivative of 14 yielded the unstable diketone 16, while hydrogenation of 14 itself followed by workup in methanol gave the lactone 17.
