Endogenous photosensitizers play a critical role in both beneficial and harmful light-induced
transformations in biological systems. Understanding their mode of action is essential for …

Pigment production is a unique character of melanocytes. Numerous factors are linked with
melanin production, including genetics, ultraviolet radiation (UVR) and inflammation …

Melanins are widely distributed in animals and plants; in vertebrates, most melanins are
present on the body surface. The diversity of pigmentation in vertebrates is mainly attributed …

The addition of thiol compounds to o-quinones, as exemplified by the biologically relevant
conjugation of cysteine to dopaquinone, displays an anomalous 1, 6-type regiochemistry …

Sclerotization of cuticle is a vital process for the survival of insects. It is caused by covalent
crosslinking of structural proteins and chitin to form hard and often coloured cuticle. During …

Alkaline reactions of chlorogenic acid (CGA) yield undesirable development of brown or
green pigments, limiting the utilization of alkalized CGA-rich foods. Thiols such as cysteine …

Instead of a conventional 'one-drug-one-target approach', this article presents a novel multi-
target approach with a concept of trap** simultaneously as many detrimental factors as …

In this work, we were interested in the search for new catalysts for catecholase, whose
principle is based on the oxidation reaction of catechol to o-quinone. In this context, a series …

In recent years, researchers have highly observed that neurological disorders (NSDs) with
the aging of the population are a global health burden whose prevalence is increasing every …

Melanin is important as a bearer of skin and hair color, that is, visual phenotype. Even within
the same species, the expressions of body color observed between individuals are diverse …
