| Description | Neoechinulin A belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. (3s,6z)-3-methyl-6-{[2-(2-methylbut-3-en-2-yl)-1h-indol-3-yl]methylidene}-3h-pyrazine-2,5-diol is found in Aspergillus stellatus, Penicillium griseofulvum and Polysiphonia stricta. (3s,6z)-3-methyl-6-{[2-(2-methylbut-3-en-2-yl)-1h-indol-3-yl]methylidene}-3h-pyrazine-2,5-diol was first documented in 2019 (PMID: 31494811). Based on a literature review a significant number of articles have been published on neoechinulin A (PMID: 32212241) (PMID: 34180325) (PMID: 35323462) (PMID: 33983974) (PMID: 33381959) (PMID: 34741824). |
