Molecular Docking, Synthesis, and Tyrosinase Inhibition Activity of Acetophenone Amide: Potential Inhibitor of Melanogenesis

mycolabadmin

Researchers developed new chemical compounds that can inhibit tyrosinase, an enzyme responsible for producing melanin (the pigment that colors skin). One compound, called 5c, proved exceptionally effective at blocking this enzyme—significantly more potent than existing skin-lightening agents. These acetophenone-based compounds could lead to improved cosmetic treatments for unwanted pigmentation like age spots and melasma, with better safety profiles than current options.

Novel tyrosinase-inhibitory peptides derived from Locusta migratoria protein hydrolysates: Preparation, identification and molecular docking analysis

mycolabadmin

Scientists have discovered that peptides from locusts can effectively inhibit tyrosinase, an enzyme responsible for skin pigmentation. These peptide extracts showed strong ability to prevent melanin production, comparable to existing skin-whitening agents but with much lower toxicity to normal cells. The research identified over 1100 different peptide sequences that could be useful in cosmetic and pharmaceutical products for treating age spots, freckles, and other pigmentation issues.

Nomilin from Yuzu Seed Has In Vitro Antioxidant Activity and Downregulates Melanogenesis in B16F10 Melanoma Cells through the PKA/CREB Signaling Pathway

mycolabadmin

Scientists extracted a compound called nomilin from yuzu seeds and tested whether it could lighten skin by reducing melanin production. They found that nomilin works by blocking an enzyme called tyrosinase that makes melanin, and it reduces the activity of cell signaling pathways involved in skin darkening. The study shows nomilin could be used as a natural skin-whitening ingredient in cosmetics without the side effects of synthetic alternatives.

Antioxidant Potential-Rich Betel Leaves (Piper betle L.) Exert Depigmenting Action by Triggering Autophagy and Downregulating MITF/Tyrosinase In Vitro and In Vivo

mycolabadmin

This research shows that betel leaves, a traditional herb used in Asian cultures, can lighten skin pigmentation through multiple mechanisms. The extract works by reducing tyrosinase enzyme activity, activating cellular cleanup processes called autophagy, and boosting the body’s natural antioxidant defenses. In both laboratory cells and living mice exposed to UV radiation, betel leaves extract effectively reduced unwanted skin darkening, suggesting it could be developed into safe natural skin-whitening products.

Tyrosinase Inhibitors Derived from Chemical Constituents of Dianella ensifolia

mycolabadmin

Researchers isolated four new plant compounds and 67 known compounds from Dianella ensifolia, a traditional Asian medicinal plant. Two of these compounds (11 and 14) were found to inhibit tyrosinase, the enzyme responsible for melanin production, making them approximately 13 times more effective than arbutin, a common cosmetic whitening ingredient. These findings suggest that D. ensifolia could be developed as a natural source of skin-whitening agents for treating age spots, freckles, and other pigmentation disorders.

Biological and Cheminformatics Studies of Newly Designed Triazole Based Derivatives as Potent Inhibitors against Mushroom Tyrosinase

mycolabadmin

Researchers developed new chemical compounds based on triazole structures to inhibit tyrosinase, an enzyme that produces melanin in skin. One compound (9h) proved particularly effective at blocking this enzyme, working 170 times better than the standard drug kojic acid. Computer modeling showed how this compound fits into the enzyme’s active site. These findings could lead to safer and more effective treatments for skin discoloration disorders like melasma and age spots.
