Novel Chemically Modified Curcumin (CMC) Derivatives Inhibit Tyrosinase Activity and Melanin Synthesis in B16F10 Mouse Melanoma Cells

Biomolecules, 2021
Skin hyperpigmentation disorders arise due to excessive production of the macromolecular pigment melanin catalyzed by the enzyme tyrosinase. Recently, the therapeutic use of curcumin for inhibiting tyrosinase activity and production of melanin have been ...

Identification of Tyrosinase Inhibitors in Cultures of Pityrosporum

Journal of Investigative Dermatology, 1978
Lipid fractions capable of inhibiting the dopa-tyrosinase reaction in vitro were isolated by thin-layer chromatography from submerged cultures of Pityrosporum supplemented with oleic acid or vaccenic acid. Analysis of these fractions by gas chromatography-mass spectrometry revealed the presence mainly of C(9) and C(11) dicarboxylic acids.

A Simulation Study of Inhibition Assay With Theophylline on the Enzymatic Hydrolysis of p‐Nitrophenyl Phosphate With Alkaline Phosphatase in a Continuous Mode of Electrophoretically Mediated Microanalysis

ELECTROPHORESIS, EarlyView.
Inhibition assays in in‐capillary continuous enzymatic reaction were simulated using a MATLAB matrix. The enzymatic hydrolysis of p‐nitrophenyl phosphate (S) with alkaline phosphatase (ALP) was adopted as a model enzymatic reaction, where theophylline (I) was used as a model inhibitor.

Tyrosinase Inhibitors from Crude Drugs.

Biological and Pharmaceutical Bulletin, 1994
Various crude drugs were examined for their tyrosinase inhibitory activity. Marked activity was observed in Chouji and Yakuchi extracts and the active substances in these extracts were identified as eugenol and yakuchinone A, respectively. Other vanillyl compounds such as ferulic acid, curcumin and yakuchinone B also had higher activities than eugenol ...

Immunomodulatory Effect of Tilapia (Oreochromis niloticus) Scale Gelatin Peptides in RAW264.7 Macrophages and Caenorhabditis elegans

Food Safety and Health, EarlyView.
ABSTRACT Currently, small‐molecular‐weight collagen peptides are a research hotspot in functional factor development due to their high bioavailability and diverse bioactivities. In this study, gelatin was extracted from tilapia (Oreochromis niloticus) scales by hot water extraction, followed by pepsin hydrolysis and ultrafiltration to obtain the < 3 ...

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.
