Neuroprotective effects of melanins and melanin derivatives from Calvatia Craniiformis and Xylaria plebeja against Parkinsonian toxins [PDF]
Scientific ReportsFungal melanins have remarkable bioactivities, but their practical applications are limited, partly due to their hydrophobic nature. Melanin modification with amino acids was reported to improve their water solubility. This research aimed to extract, and

Characterization of Fungal Melanins from Black Stains on Paper Artefacts
Heritage, 2022 Melanins play a fundamental role in the biology and ecology of several fungal species. Unfortunately, this group of amorphous macromolecules also severely (and most times irreversibly) stains cultural heritage objects. Despite efforts made throughout the

Physico-chemical evaluation of rationally designed melanins as novel nature-inspired radioprotectors. [PDF]
PLoS ONE, 2009 Melanin, a high-molecular weight pigment that is ubiquitous in nature, protects melanized microorganisms against high doses of ionizing radiation. However, the physics of melanin interaction with ionizing radiation is unknown.We rationally designed ...
