    Synthesis, Characterization, and Evaluation of Thiazolidine Derivatives of Cysteine for Suppressing Eumelanin Production.
    Chem Pharm Bull (Tokyo) 2016 ;64(12):1681-1691
    Institute for Innovation, Ajinomoto Co., Inc.
    In the pathway of melanin biosynthesis, cysteine (Cys) is utilized for the synthesis of pheomelanin. Accordingly, Cys is considered to suppress the formation of brown-black eumelanin. Although attempts have been made to utilize Cys and its derivatives as skin-whitening agents, their instability and odor hinders their application as a cosmetic agent. Read More

    Melanoma Res 2016 Jun;26(3):211-22
    aLaboratory of Cellular and Molecular Biology, Faculty of Dental Medicine bUnit of Natural and Bioactive Substances and Biotechnology, Faculty of Pharmacy, University of Monastir, Monastir, Tunisia cLaboratory of Pharmacognosy, Faculty of Pharmacy, University of Lille 2, Lille, France.
    The lack of an efficient agent that does not have the disadvantage of low activity (kojic acid), high cytotoxicity, and mutagenicity (hydroquinone), poor skin penetration (arbutin), or low stability in formulation (glabridin) led us to continue our research on new antipigmentation/skin-lightening agents. Therefore, research of natural products that can modulate the metabolism of pigmentation is of great interest. Otherwise, malignant melanoma is one of the most aggressive forms of skin cancer, with high metastatic potential, and currently, there is no effective chemotherapy against invasive melanoma.

    A Game-Theoretic Model of Marketing Skin Whiteners.
    Health Mark Q 2015 13;32(4):367-81. Epub 2015 Nov 13.
    a School of Business , Wilmington University , New Castle , DE.
    Empirical studies consistently find that people in less developed countries tend to regard light or "white" skin, particularly among women, as more desirable or superior. This is a study about the marketing of skin whiteners in these countries, where over 80 percent of users are typically women. It proceeds from the following premises: a) Purely market or policy-oriented approaches toward the risks and harms of skin whitening are cost-inefficient; b) Psychosocial and informational factors breed uninformed and risky consumer choices that favor toxic skin whiteners; and c) Proliferation of toxic whiteners in a competitive buyer's market raises critical supplier accountability issues.

    HPLC-UV Method for the Identification and Screening of Hydroquinone, Ethers of Hydroquinone and Corticosteroids Possibly Used as Skin-Whitening Agents in Illicit Cosmetic Products.
    J Chromatogr Sci 2016 Mar 13;54(3):343-52. Epub 2015 Oct 13.
    Agence Nationale de Sécurité du Médicament et des Produits de Santé (ANSM), Direction des Contrôles (CTROL), 143/147 boulevard Anatole France, 93285 Saint-Denis Cedex, France.
    Corticosteroids, hydroquinone and its ethers are regulated in cosmetics by the Regulation 1223/2009. As corticosteroids are forbidden to be used in cosmetics and cannot be present as contaminants or impurities, an identification of one of these illicit compounds deliberately introduced in these types of cosmetics is enough for market survey control. In order to quickly identify skin-whitening agents present in illegal cosmetics, this article proposes an HPLC-UV method for the identification and screening of hydroquinone, 3 ethers of hydroquinone and 39 corticosteroids that may be found in skin-whitening products.

    Design, synthesis, and anti-melanogenic effects of (E)-2-benzoyl-3-(substituted phenyl)acrylonitriles.
    Drug Des Devel Ther 2015 4;9:4259-68. Epub 2015 Aug 4.
    College of Pharmacy, Pusan National University, Busan, Republic of Korea.
    Background: Tyrosinase is the most prominent target for inhibitors of hyperpigmentation because it plays a critical role in melaninogenesis. Although many tyrosinase inhibitors have been identified, from both natural and synthetic sources, there remains a considerable demand for novel tyrosinase inhibitors that are safer and more effective.

    Methods: (E)-2-Benzoyl-3-(substituted phenyl)acrylonitriles (BPA analogs) with a linear β-phenyl-α,β-unsaturated carbonyl scaffold were designed and synthesized as potential tyrosinase inhibitors. Read More

    4-n-butylresorcinol dissolving microneedle patch for skin depigmentation: a randomized, double-blind, placebo-controlled trial.

    Department of Chemistry, Fujita Health University School of Health Sciences, Toyoake 470-1192, Japan.
    Background: Rhododendrol (RD), a skin-whitening agent, is believed to be associated with cases of cosmetics-related leukoderma that have been reported in Japan. Recently, we have shown that RD is catalyzed by tyrosinase to produce putative toxic metabolites RD-catechol and RD-cyclic catechol.

    Objective: To examine the cytotoxicity and production of reactive oxygen species (ROS) in melanocytic cells by RD and its metabolic products. Read More

    Callicarpa longissima extract, carnosol-rich, potently inhibits melanogenesis in B16F10 melanoma cells.

    Development of Tyrosinase Promoter-Based Fluorescent Assay for Screening of Anti-melanogenic Agents.
    Biol Pharm Bull 2015 15;38(10):1542-7. Epub 2015 Jul 15.
    Biospectrum Life Science Institute.
    For screening of skin-whitening ingredients that modulate inhibition of melanogenesis, tyrosinase promoter-based assay using a three-dimensional (3D) spheroid culture technique is a beneficial tool to improve the accuracy of raw material screening in cosmetics through mimicking of the in vivo microenvironment. Although the advantages of high-throughput screening (HTS) are widely known, there has been little focus on specific cell-based promoter assays for HTS in identifying skin-whitening ingredients that inhibit accumulation of melanin. The aim of this study was therefore to develop a large-scale compatible assay through pTyr-EGFP, an enhanced green fluorescent protein (EGFP)-based tyrosinase-specific promoter, to seek potential melanogenesis inhibitors for cosmetic use.

    4-Hexylresorcinol (HR) is a compound used in the food and cosmetic industries as an antibrowning and lightening agent. Its use is mainly attributed to its inhibitory effect on the enzyme tyrosinase. However, the enzyme hydroxylates HR to an o-diphenol, which it then oxidizes to an o-quinone, which rapidly isomerizes to p-quinone. Read More

    An open-label, single-arm trial of the safety and efficacy of a novel preparation of glutathione as a skin-lightening agent in Filipino women.

    Effect of the combination of different depigmenting agents in vitro.
    J Cosmet Sci 2014 Nov-Dec;65(6):365-75
    Melanin plays a key role in our skin, protecting us against ultraviolet radiation, but there are situations in which its anomalous accumulation can lead to either aesthetic problems or diseases like melasma. For this reason, it is important to find agents that are able to decrease the skin pigmentation. It has been demonstrated that the melanin synthesis pathway can be inhibited at different levels by different mechanisms of action. Read More
