Nemadectin, initially described as LL-F28249-a, is a macrocyclic lactone antibiotic demonstrating broad-spectrum endectocidal and nematocidal activity. Nemadectin bears structural similarity to the milbemycin and avermectin antibiotics, differing by the unsaturated side-chain extending from the 6,6-spiroketal core of the antibiotic. Nemadectin has demonstrated efficacy against the natural canine-infecting helminths and against ivermectin-resistant|Haemonchus contortus|in sheep.

| Beschreibung | This compound 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. |
