Itch suppression by fucoxanthin
View Patent ↗The present invention provides a method of suppressing mast cell differentiation and/or itch in the skin of a subject, comprising topically administering to the skin in need thereof an effective amount of fucoxanthin or a derivative thereof.
1. A method of suppressing mast cell differentiation in the skin of a subject, comprising topically administering to the skin in need thereof an effective amount of fucoxanthin, fucoxanthinol, amarouciaxanthin A, a monoester of fucoxanthin selected from esters with amino acids, esters with carboxylic acids and salts thereof, esters with inorganic acids and salts thereof, fatty acid esters with highly unsaturated fatty acids, unsaturated fatty acids, and saturated fatty acids, a diester of fucoxanthin having the same or different ester groups, or a glycoside.
2. A method of suppressing itch in the skin of a subject, comprising topically administering to the skin in need thereof an effective amount of fucoxanthin, fucoxanthinol, amarouciaxanthin A, a monoester of fucoxanthin selected from esters with amino acids, esters with carboxylic acids and salts thereof, esters with inorganic acids and salts thereof, fatty acid esters with highly unsaturated fatty acids, unsaturated fatty acids, and saturated fatty acids, a diester of fucoxanthin having the same or different ester groups, or a glycoside.
3. The method of claim 2 , wherein fucoxanthin is administered to the skin.
4. The method of claim 2 , wherein fucoxanthinol is administered to the skin.
5. The method of claim 2 , wherein amarouciaxanthin A is administered to the skin.
6. The method of claim 2 , wherein a monoester of fucoxanthin selected from esters with amino acids, esters with carboxylic acids and salts thereof, esters with inorganic acids and salts thereof, fatty acid esters with highly unsaturated fatty acids, unsaturated fatty acids, and saturated fatty acids is administered to the skin.
7. The method of claim 2 , wherein a diester of fucoxanthin having the same or different ester groups is administered to the skin.
8. The method of claim 2 , wherein a glycoside is administered to the skin.
9. The method of claim 1 , wherein fucoxanthin is administered to the skin.
10. The method of claim 1 , wherein fucoxanthinol is administered to the skin.
11. The method of claim 1 , wherein amarouciaxanthin A is administered to the skin.
12. The method of claim 1 , wherein a monoester of fucoxanthin selected from esters with amino acids, esters with carboxylic acids and salts thereof, esters with inorganic acids and salts thereof, fatty acid esters with highly unsaturated fatty acids, unsaturated fatty acids, and saturated fatty acids is administered to the skin.
13. The method of claim 1 , wherein a diester of fucoxanthin having the same or different ester groups is administered to the skin.
14. The method of claim 1 , wherein a glycoside is administered to the skin.
