Metabolite Identification
Common NameNX-2
DescriptionNX-2 is a type A trichothecene mycotoxin belonging to the chemical class of sesquiterpenes. Its chemical structure is characterized by a complex arrangement of carbon rings and functional groups, including a hydroxyl group at the 7α position and a deacetylated moiety, specifically 15-deacetylcalonectrin. NX-2 is primarily produced by various isolates of Fusarium graminearum, a fungal pathogen known for its ability to generate multiple mycotoxins, including NX-3 (7-α hydroxy, 3,15-dideacetylcalonectrin). The genetic diversity among these isolates influences the specific trichothecene production phenotypes, with NX-2 being one of the predominant toxins produced. Pathways involving NX-2 include its synthesis through polyketide biosynthesis, which is regulated by specific genetic determinants within the F. graminearum genome. The identification and differentiation of NX-2 producers from other chemotypes have been facilitated by molecular tools such as high-resolution melting assays, which target specific genetic markers associated with the NX-2 genotype. This mycotoxin's production has been documented in various geographical regions, including Canada and Argentina, highlighting its relevance in agricultural contexts (PMIDs: 40559862, 39852992, 39738214, 39342961).
