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

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.

Anti-Melanogenic Activity of Calocedrus formosana Wood Essential Oil and Its Chemical Composition Analysis

Researchers tested an essential oil from Taiwan’s precious Calocedrus formosana wood to see if it could lighten skin by blocking melanin production. The oil worked very well at stopping melanin synthesis in laboratory cells, with a compound called thymol being responsible for most of the lightening effect. This natural product could potentially be used in skin whitening cosmetics and offers a safer alternative to synthetic ingredients.

Eumelanin Detection in Melanized Focal Changes but Not in Red Focal Changes on Atlantic Salmon (Salmo salar) Fillets

Farmed Atlantic salmon sometimes develop unsightly black and red spots that reduce market value. Researchers analyzed these discolored areas and found that the black spots contain a type of melanin pigment (eumelanin) produced by immune cells called melanomacrophages. The red spots contain different compounds formed from oxidized proteins rather than true melanin. Understanding the chemical differences between these two types of spots could help salmon farmers develop better prevention strategies.
