7,10-Dimethoxy-10-DAB III Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung

Cabazitaxel is a kind of Second line Drug for the treatment of prostate cancer, FDA Priority Review status approval listing is obtained because its curative effect is remarkable, for the advanced prostate cancer patients to the invalid even aggravation of Docetaxel, the first-selected medicine being used for the treatment of late period, hormone antagonist type prostate cancer.7,10-dimethoxy-10-Dab III is the important intermediate preparing Cabazitaxel.

Verwenden

4-Deacetyl-4-propionyl Cabazitaxel is an impurity of Cabazitaxel (C046500).A novel semi-synthetic taxane with antitumor activity used for the treatment of castration-resistant prostate cancer. A microtubule inhibitor.

Synthese

Solvent is methylene dichloride, and alkali is the two dimethylamino naphthalene of 1,8-, and the mol ratio of 10-deacetylate Bakating III and trimethylammonium oxygen Tetrafluoroboric acid is 1:35; The mol ratio of 10-deacetylate Bakating III and alkali is 1:45;By 10-Dab (10g, 18.4mmol) be dissolved in methylene dichloride (200ml), add 1, the two dimethylamino naphthalene (177.2g of 8-, 828mmol), stirring at room temperature half an hour, add trimethylammonium oxygen Tetrafluoroboric acid (95.2g, 643.4mmol) again, stirring at room temperature 20h, suction filtration reaction solution, filter cake methylene dichloride washes 3 times, collects filtrate, and after concentrated, column chromatography (chloroform: methyl alcohol=100:3) obtains 7,10-dimethoxy-10Dab III 4.6g, yield 43.7%.
