Patent number: 6218367Abstract: The present invention provides novel, water soluble, carbohydrate derivatives of paclitaxel, methods of treatment and pharmaceutical compositions that utilize or comprise one or more of such compounds. The compounds of the invention are modified at the 2′ or 7 position of paclitaxel and have the general formula [paclitaxel]-[link]1−2-[sugar]. These compounds show improved biological activity toward many cancer cell lines as compared to paclitaxel. Additionally, the conjugates are made from natural non-toxic materials which, when released, will be adsorbed as part of the body components.Type: GrantFiled: September 14, 1999Date of Patent: April 17, 2001Assignee: Organomed CorporationInventor: James N Jacob
