Description

Albonoursin belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-member aromatic heterocycle, that consists of two nitrogen atoms (at positions 1 and 4) and four carbon atoms. Albonoursin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. It was first documented in 2009 (PMID: 19430487). Based on a literature review a significant number of articles have been published on albonoursin (PMID: 30901830) (PMID: 35722152) (PMID: 31175189) (PMID: 25048158).
