Tyrosinase
Tyrosinase is a copper-containing metalloprotein belonging to the type-3 copper protein family, together with haemocyanins and catechol oxidases. Tyrosinases are the catalysts in mammals responsible for the formation of melanin in skin and hair color, as well as browning in fruit and vegetables following cell damage.
Tyrosinases are found in various prokaryotes as well as in plants, fungi, arthropods, and mammals and are responsible for pigmentation, wound healing, radiation protection, and primary immune response. Tyrosinases perform two sequential enzymatic reactions: hydroxylation of monophenols and oxidation of diphenols to form quinones which polymerize spontaneously to melanin. In plants, sponges, and many invertebrates, tyrosinases are important for wound healing and primary immune responses; in arthropods, they play a role in sclerotization, and in bacteria, tyrosinases protect DNA from UV damage.

N-Acetyl-4-S-cysteaminylphenol
0 ImagesCat. No.: HY-W129441CAS No.: 91281-32-2Synonyms: N-Ac-4-S-CAPN-Acetyl-4-S-mercaptoaminophenol (N-Ac-4-S-CAP) is a compound that is selectively cytotoxic to melanocytes of black mouse hair follicles. It can cause 98% depigmentation of black mouse hair follicles. N-Ac-4-S-CAP can produce visible changes in hair follicle melanocytes 4 hours after intraperitoneal injection, including aggregation of melanin granules and nuclear condensation. Electron microscopy observations showed that it caused progressive destruction of melanocytes, including swelling of membranous organelles, nuclear condensation, and cytoplasmic vacuolation, ultimately leading to complete cell necrosis. N-Ac-4-S-CAP has a specific cytotoxic effect on melanocytes that actively produce eumelanin, but may not affect precursor or dormant melanocytes. These properties suggest that N-Ac-4-S-CAP may have potential application value in the treatment of melanoma or skin whitening.
