(54) ANTICANCER AGENTS, PERFUMES OR FOODS AND DRINKS CONTAINING OMEGA-HYDROXY FATTY ACIDS


(57) The present invention relates to drugs and, particularly, to anticancer agents.
More particularly, the present invention relates to an anticancer agents containing, as an active ingredient, at least one compound selected from the group consisting of ω-hydroxy fatty acids and salts or esters thereof, hydroxy oxo-fatty acids and salts or esters thereof, lactones, macrocyclic ketones, and macrocyclic diesters having specific chemical structures.
With respect to the compounds described above used in the present invention, since the activities of killing cancer and inhibiting cancer metastasis are significantly high, the effects of preventing the recurrence of cancer and preventing cancer are exhibited, the cytotoxicity is significantly low, and a small dose is effective, it is possible to provide anticancer agents having significantly decreased side effects. Additionally, use in combination with known antitumor agents can further enhance the activity of inhibiting cancer metastasis. Among the anticancer agents of the present invention, ω-hydroxy fatty acids can be easily obtained in high purities by hydrolyzing lactones which are also the anticancer agents of the present invention.
