Abstract

The invention belongs to the technical field of medicine, relates to novel use of PK11195, and particularly relates to the use of PK11195 or a pharmaceutically acceptable salt thereof in the preparation of a medicine/cosmetic for treating and/or preventing hyperpigmented diseases, especially the use in preparation of a medicine/cosmetic for treating and/or preventing various hereditary, ultraviolet and inflammatory factors-induced hyperpigmentation such as freckles, pregnancy spots, melasma, coffee spots and moles.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a new application of PK11195. Background technique [0002] Skin melanin plays an important role in people's normal social interaction and protection from ultraviolet radiation. Various factors in vivo and in vitro, such as α-melanostimulating hormone (α-MSH), adrenocorticotropic hormone (ACTH), and ultraviolet rays can induce melanin synthesis. However, if a large amount of melanin accumulates in the skin, it will lead to hyperpigmentation diseases, such as freckles, pregnancy spots, chloasma, coffee spots, moles, ultraviolet-induced pigmentation, and hereditary dark skin. Hyperpigmentation diseases not only seriously affect the appearance of patients, but also cause great mental stress to them, and even induce skin cancers, such as melanoma. With the improvement of living standards, people pay more attention to the prevention and treatment of such diseases. [00...
