Common Name

Aspernigrin A

Description

Aspernigrin A is a secondary metabolite belonging to the chemical class of alkaloids. It has been identified in various fungal species, particularly from marine-derived Aspergillus niger, where it coexists with other compounds such as pyrones and quinones (PMID:40624613 ). This compound has garnered attention for its potential biological activity, particularly its inhibitory effects on acetylcholine esterase (AChE), which is significant in the context of Alzheimer's disease (PMID:34506550 ). The structural characterization of aspernigrin A has evolved, with its initial structure being revised from 4-benzyl-6-oxo-1,6-dihydropyridine-3-carboxamide to 6-benzyl-4-oxo-1,4-dihydropyridine-3-carboxamide based on advanced NMR and X-ray crystallographic analyses (PMID:16038560 ). Additionally, it has been reisolated from the endophytic fungus Cladosporium herbarum associated with Cynodon dactylon, highlighting its ecological relevance and potential pharmaceutical applications (PMID:16038560 ). The exploration of its biosynthetic pathways and interactions within fungal ecosystems continues to be an area of interest in both chemistry and biology.
