Common Namenemadectin
DescriptionNemadectin, also known as LL-F28249 beta or LL-F 28249GAMMA, belongs to the class of organic compounds known as milbemycins. These are a group of macrolides with a structure containing a 16-membered lactone ring fused to a 1,7-dioxaspiroundecane ring system and to either a benzofuran (or hydrogenated derivative thereof). In some cases (e.G. Milbemycin E), the tetrahydrofuranyl ring is missing. Milbemycins can be o-glycosylated at C13 to form Avermectins. Milbemycins are produced by Streptomyces species. nemadectin is found in Streptomyces cyaneogriseus and Streptomyces microflavus. nemadectin was first documented in 2019 (PMID: 31208455). Based on a literature review a small amount of articles have been published on Nemadectin (PMID: 32323213) (PMID: 34437755) (PMID: 32695892) (PMID: 33224938).
