9 Novel polysaccharide pro-drug 5-fluorouracil (5-FU) with enhanced target specificity for colorectal cancer and its preparation methods US11657753 2007-09-17 US20080085871A1 2008-04-10 Joemy Tam; Qi Mei; Li Liu; Qing Wang
This invention describes a novel polysaccharide prodrug of 5-fluorouracil (5-FU) with enhanced target specificity for colorectal cancer treatment, and its preparation methods. The prodrug is synthesized by chemically linking anti-cancer drug 5-fluorouracil (5-FU) with a specially selected polysaccharide with molecular weight of 105˜107 Da containing galactose residues. Its distinctive characteristics are that it is a prodrug synthesized by chemically linking polysaccharides with 5-FU through different bridge links for the targeted treatment of colorectal cancer; that the polysaccharides in the chemical compound contain galactose residues; and that these polysaccharides are prepared from natural gums or plant materials. Due to these unique characteristics, as an oral preparation, the polysaccharide component of this novel prodrug can protect the active agent 5-FU from absorption (or metabolism) in the upper gastrointestinal tract and deliver a high concentration of the 5-FU to the colorectal area. Upon reaching the colorectal area, the 5-FU-galactose portion of the prodrug will bind to galectin-3, a-galactoside-binding protein implicated in tumor progression by interactions with its ligands, such as TF (Thomsen-Friedenreich, Galb3GalNAc), Tn (GalNAcaThr/Ser), and Sialy-Tn with galactose residues, which are highly expressed among colorectal cancer cells. Finally, the active 5-FU component will be released locally from the polysaccharide via enzymatic hydrolysis from the local bacterial flora, allowing it to actively kill the colorectal cancer cells. In summary, this novel target-specific prodrug can enhance the selectivity of 5-FU and increase its therapeutic effects in the treatment of colorectal cancer. In addition, with this enhanced target specificity, it is possible to maximize the 5-FU efficacy in cancer patients by having either less toxicity with the same or higher therapeutic dose, and/or administer a lower dosage (if so desired) to achieve the same therapeutic effects, but with much less toxicity. Multiple examples of various approaches to synthesize this novel prodrug are enclosed herein along with several animal model experiments to substantiate the claims as stated above.
10 Polysacchocride prodrug of 5-fluorouracil (5-FU) with enhanced target specificity for galectin-3 expressing cancers US11657754 2007-09-17 US20080004237A1 2008-01-03 Joemy Tam; QiBing Mei; Dale Choi
This application discloses embodiments of a novel prodrug and its method of synthesis. The prodrug comprises a galactose-containing polysaccharide covalently linked to 5-fluorouracil (5-FU). The galactose residues that are part of the backbone of the galactose-containing polysaccharide mediate the binding between the prodrug and the lectin galectin-3 which is expressed in various cancers. The galactose-containing polysaccharide is isolated from various plant material and covalently bonded to 5-FU. Various formulations (parenteral, or other local or systemic forms) can be used to administer this 5-FU-releasing prodrug to target galectin-3 expressing cancers.

15 Methods for the extraction of phytochemicals from fibrous plants in the absence of solvent US571231 1995-12-12 US5756098A 1998-05-26 Christopher H. Price; Dale Hedtke; Geoffrey N. Richards; Michael S. Tempesta
Methods and apparatus are provided for the recovery of organic compounds from fibrous plant materials. Organic compounds which can be recovered from the fibrous plant materials include plant metabolites, such as arabinogalactan and phenols, which can be isolated from the wood, for example, of the Western Larch and Tamarack tree varieties. In addition to the recovery of organic compounds from wood, fibrous wood products also may be isolated, in the form of a clean fiber that can be used, for example, as raw material in wood processing applications or in the manufacture of high quality paper products. In one embodiment, a fibrous plant material first is compressed, to recover a liquid exudate and a first pressed plant fiber product. Optionally, the fibrous plant material, such as wood particles, is compressed in the substantial absence of any added solvent, to produce a pure normal liquid exudate and a first pressed plant product. The first plant fiber product then may be impregnated with, for example, an aqueous solvent, to recover an extract liquor and impregnated plant fiber. The impregnated plant fiber then is compressed to recover a liquid pressate and a second pressed fiber product. Using these methods, in one embodiment, a substantially pure arabinogalactan exudate and a wood fiber product can be recovered from wood of the genus Larix, with minimal coextraction of phenols. Additionally, a variety of different plant metabolites may be isolated and/or identified from different kinds of woody plants using the methods and apparatus.
