Abstract

Official abstract text for this publication.

The present invention is directed to inhibitors of tyrosinase, pharmaceutical compositions comprising such tyrosinase inhibitors, and methods of making and using the same. Specifically, included in the present invention are compositions of matter comprised of at least one 2,4-dihydroxybenzene analog, which inhibit the activity of tyrosinase and which inhibit the overproduction of melanin.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compound selected from 4′-methoxybiphenyl-2,4-diol, and 4-(4′-hydroxybiphenyl)benzene-1,3-diol. 2. A method for preventing and treating diseases and conditions related to the overproduction or uneven distribution of melanin comprising administering to a subject in need thereof an effective amount of a composition comprising one or more compounds selected from the group consisting of 4′-methoxybiphenyl-2,4-diol, and 4-(4′-hydroxybiphenyl)benzene-1,3-diol. 3. The method of claim 2 , wherein the diseases and conditions are selected from the group consisting of damage resulting from exposure to the sun or ultraviolet (UV) radiation, suntan, hyper pigmentation spots caused by skin aging, melasma, liver diseases, thermal burns and topical wounds, skin pigmentation due to inflammatory conditions cased by fungal, microbial and viral infections, vitilago, carcinoma, melanoma. 4. A composition comprising the compound of claim 1 and a pharmaceutically or cosmetically acceptable carrier. 5. A method of inhibiting the browning or color changes in fruits, vegetables, juices and other fruit products by administering a composition comprising the compound of claim 1 . 6. A method of inhibiting the activity of tyrosinase in a patient by administering a composition comprising the compound of claim 1 . 7. A method of inhibiting the activity of melanin in a patient by administering a composition comprising the compound of claim 1 . 8. A method of whitening, lightening, or a combination thereof, the skin of a patient by administering a composition comprising the compound of claim 1 .
