Skin hyperpigmentation is characterized as increased production and accumulation of melanin, which could be aesthetically unfavorable and develops serious skin diseases. There is a need to find new depigmenting agents, since many current natural and synthetic products present undesired side effects. In Iranian traditional medicine (ITM), plants have been used for the treatment of skin diseases ...

Because tyrosinase catalyzes melanin synthesis, tyrosinase inhibitors are important in cosmetic skin-whitening. Oxidative stress contributes to skin aging and can adversely affect skin health, which means antioxidants active in skin cells may support skin health. We examined 25 traditional Chinese herbal medicines that might be useful for skin-whitening and skin health. Extracts (100microg/mL) ...

Sappanwood (Caesalpinia sappan Linn.) is used as an herbal medicine. It is sometimes used to treat skin damage or as a facial cleanser. In the present study, the methanol (MeOH) extract of sappanwood was found to inhibit melanin synthesis in cultured human melanoma HMV-II cells stimulated with forskolin, and six active compounds (1-5 and 7) were isolated from the extract along with a non-active...

We previously demonstrated that the oncogenic kinase PAK4, which both melanomas and normal melanocytes express at a very high level, is essential for their melanogenesis. In the present study, using the highly sensitive "Macaroni-Western" (IP-ATP-Glo) kinase assay, we investigated the melanogenic potential of another oncogenic kinase PAK1, which melanoma (B16F10) cells express only at a very mi...

Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...

due to the destruction of the ozone layer. Our skin is more exposed to UV radiation and often suffers from various harmful effects of UV. Melanin prodcution in human skin is an important defense mechanism against UV and a major determinant of skin color. Melanocytes residing within the basal layer of the epidermis synthesize melanin in specialized organelles, designated as melanosomes, by coord...
