Aspernigrin A

Description

Aspernigrin A belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. Aspernigrin A is found in Aspergillus niger, Cladosporium herbarum IFB-E002 and Pseudopestalotiopsis theae. Aspernigrin A was first documented in 2005 (PMID: 16038560). Aspernigrin A is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 26669099).
