Description

Rubrofusarin B is a naphtho-γ-pyrone derivative, a class of compounds known for their diverse biological activities. Its chemical structure features a naphthalene ring system fused with a γ-pyrone moiety, contributing to its unique properties. This compound has been isolated from various fungal sources, including marine-derived Aspergillus species, such as Aspergillus cosatricaensis and Aspergillus niger, where it was identified alongside other metabolites like butyrolactones and alkaloids (PMID:35599958 , PMID:34506550 ). Rubrofusarin B has been shown to exhibit inhibitory activity against acetylcholinesterase (AChE), an enzyme implicated in Alzheimer’s disease, suggesting potential neuroprotective pathways (PMID:34506550 ). Additionally, it has been observed to block corticosterone-induced impairments in long-term potentiation, indicating a role in synaptic plasticity and cognitive function (PMID:32414166 ). The compound's presence in various fungal strains highlights its significance in the biosynthetic pathways of secondary metabolites, which are crucial for the ecological interactions of these fungi.
