Special Issue Information

Dear Colleagues,

Melanogenesis is a pigment-producing process that occurs ubiquitously in all animals, as well as in a wide variety of microorganisms and plants. The enzyme tyrosinase (also known as phenoloxidase) initiates melanogenesis by hydroxylating monophenols to create o-diphenols; these o-diphenols are further oxidized by tyrosinase into o-quinones. The unstable o-quinones undergo rapid transformations that are both nonenzymatic and enzyme catalyzed. Eventually, these transformations create different kinds of polymeric products.

Quinones in general are very reactive and tend to deplete cellular antioxidant pools. They also have deleterious effects on cellular macromolecules. In light of the above, inhibitors of melanogensis have great commercial potential.

For example, oxidative browning reactions reduce the nutritive values of plants. On the other hand, these reactions are advantageous for plants because they help fight off infection and invasion by other organisms. Nevertheless, oxidative browning certainly reduces the market value of food products.

The melanosis observed in crustaceans similarly reduces the market value of seafood drastically. In arthropods and especially insects, melanogenesis is used for wound healing and defense reactions (invertebrate immunity). A parallel process called sclerotization (which is initated through phenoloxidases), ensures the hardening of insect exoskeletons, so as to protect these soft-bodied animals from their environmental enemies. Arrest or even delay of sclerotization has devastating consequences for insects. Consequently, the inhibition of sclerotization provides a valuable tool for fighting noxious insects, and for developing new kinds of insecticides for future use.

Mammals use melanin mostly as skin, coat, and eye pigments. In recent years, dermal melanin production inhibitors have become a valuable tool for the cosmetic industry to produce lighter skin.

Thus, melanogenesis inhibitors have many useful applications. Naturally, lots of research groups have been engaged in discovering novel inhibitors of these enzymes. This Special Issue, which is the second of a series, will cover broad range topics, which include phenoloxidase/tyrosinase chemistry, biochemistry of inhibitors, and methods of either discovering or developing novel bioactive compounds (both natural and synthetic) that inhibit melanogenesis and related processes.  This new Special Issue aims to cover the most recent progress made in this area, and will include research papers and authoritative review articles.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed Open Access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs).
