Methods of inhibition of protein fucosylation in vivo using fucose analogs
The invention provides methods and compositions for the inhibition of fucosylation of proteins, including antibodies, in vivo by administration of a fucose analog.
1. A method for the treatment of cancer in a human in need thereof, comprising administering orally to the human a therapeutically effective amount of a fucose analog, or a composition thereof,
wherein the cancer is a solid tumor having protein fucosylation; and
wherein each fucose analog has formulae (V) or (VI):
or a biologically acceptable salt or solvate thereof, wherein each fucose analog of formula (V) or (VI) can be the alpha or beta anomer or the corresponding aldose form;
wherein each of R 1 , R 3 , and R 4 is independently selected from the group consisting of —OH and —OC(O)C 1 -C 10 alkyl, R 2 is F, R 2a and R 3a are each H, and R 5 is —CH 3 .
2. The method of claim 1 wherein said fucose analog is 2-deoxy-2-fluoro-L-fucose.
3. The method of claim 1 wherein said fucose analog is 2-deoxy-2-fluoro-L-fucose peracetate.
4. The method of claim 1 further comprising administering a tumor-associated antigen or an antigenic fragment thereof as an immunogen.
5. The method of claim 1 further comprising administering a chemotherapeutic agent.
6. The method of claim 1 wherein the solid tumor is breast cancer.
7. The method of claim 1 wherein the solid tumor is lung cancer.
8. The method of claim 1 wherein the solid tumor is renal cell carcinoma.
9. The method of claim 1 wherein administration of the therapeutically effective amount is in the form of one or more dosage units.
