Disclosure of mystery of “fairy rings” by chemistry was written by Kawagishi, Hirokazu. And the article was included in Yuki Gosei Kagaku Kyokaishi in 2015.Reference of 26832-08-6 This article mentions the following:
A review on chems. responsible for “fairy rings” of turf grass, their formation through a new purine metabolic pathway, and chem. synthesis of 13C,15N-labeled metabolites. 2-Azahypoxanthine (AHK, I) (rice plant-growth promotor) and imidazole-4-carboxamide (ICA, II) (turf grass growth inhibitor) were isolated from a fairy-ring forming fungus Lepista sordida. AHK was converted into a metabolite, 2-aza-8-oxohypoxanthine (AOH, III) (turf grass growth-promoters), in plants. Afterward, it turned out that these three compounds, fairy chems. (FSc), endogenously exist in plants and are biosynthesized via a new purine metabolic pathway. Furthermore, FCs increased the yields of rice, wheat and other crops in the field experiments In the experiment, the researchers used many compounds, for example, 1H-Imidazole-4-carboxamide (cas: 26832-08-6Reference of 26832-08-6).
1H-Imidazole-4-carboxamide (cas: 26832-08-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Reference of 26832-08-6
