Antioxidant, neuroprotective, and neuroblastoma cells (SH-SY5Y) differentiation effects of melanins and arginine-modified melanins from Daedaleopsis tricolor and Fomes fomentarius [PDF]
Background Microbial melanins possess a broad spectrum of biological activities. However, there is little understanding of their neuroprotective and neuronal cell differentiation properties.

Characterization of Fungal Melanins from Black Stains on Paper Artefacts [PDF]
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

Fungal melanins differ in planar stacking distances. [PDF]
Melanins are notoriously difficult to study because they are amorphous, insoluble and often associated with other biological materials. Consequently, there is a dearth of structural techniques to study this enigmatic pigment.

Physico-chemical evaluation of rationally designed melanins as novel nature-inspired radioprotectors. [PDF]
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 ...

Fungal Melanins as Potential Reactive Oxygen Species-Scavenging Neuroprotective Agents [PDF]
Oxidative stress is strongly associated with neuronal damage in neurodegenerative diseases, such as Parkinson’s disease (PD). Fungal melanins are remarkable free radical scavengers; however, their capacity to protect neurons from reactive oxygen species (

Neuroprotective effects of melanins and melanin derivatives from Calvatia Craniiformis and Xylaria plebeja against Parkinsonian toxins [PDF]
Fungal 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
