Studies on Inhibition of Tyrosinase

Experimental Biology and Medicine, 1954
SummaryUsing a previously described spot-spray technic, more than 400 simple, aromatic compounds were investigated as inhibitors of tyrosinase. 4-Chlororesorcinol inhibited melanin formation from tyrosine, DOPA or epinephrine at a concentration of 10-9; it was thus 20,000 times more potent than resorcinol.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Patchouli Alcohol: A Potent Tyrosinase Inhibitor Derived from Patchouli Essential Oil with Potential in the Development of a Skin-Lightening Agent

Cosmetics
The inhibitory effects of Pogostemon cablin essential oil (patchouli essential oil, PEO) and its primary bioactive compound, patchouli alcohol (PA), on tyrosinase and melanin were investigated in vitro and ex vivo. Treatment with PEO and PA significantly,

Anti-Melanogenic Effects of Flavonoid Glycosides from Limonium tetragonum (Thunb.) Bullock via Inhibition of Tyrosinase and Tyrosinase-Related Proteins

Molecules, 2017
Overproduction and stimulation of tyrosinase result in increased melanogenesis of which several skin disorders such as freckles, spots, and hyperpigmentation appear as complications.

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 6002-6014, 15 August 2026.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease

Polyphenol oxidase depletion in Nicotiana benthamiana enhances recombinant protein purification and preserves native protein integrity

New Phytologist, Volume 251, Issue 3, Page 1283-1293, August 2026.
Polyphenol oxidases (PPOs) depletion preserves endogenous proteins at their predicted molecular weights and enhances detectable enzymatic activities. (a) Less RbcL crosslinking in ppo mutant of Nicotiana benthamiana. Leaf extracts were incubated for 1 h, separated on protein gels, stained with Coomassie or analyzed by Western blot with the anti‐RbcL ...

Ligand‐Level Chemical Activation: Coordination with Benefits

European Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups
