Common Name(1'r,2r,4's,5s,6r,8'r,10'z,13'r,14'z,20'r,21'r,24's)-21',24'-dihydroxy-6-isopropyl-5,11',13',22'-tetramethyl-3',7',19'-trioxaspiro[oxane-2,6'-tetracyclo[15.6.1.1⁴,⁸.0²⁰,²⁴]pentacosane]-10',14',16',22'-tetraen-2'-one
DescriptionMilbemycin D, also known as milbemycin BETA2 or cydectin, 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. (1'r,2r,4's,5s,6r,8'r,10'z,13'r,14'z,20'r,21'r,24's)-21',24'-dihydroxy-6-isopropyl-5,11',13',22'-tetramethyl-3',7',19'-trioxaspiro[oxane-2,6'-tetracyclo[15.6.1.1⁴,⁸.0²⁰,²⁴]pentacosane]-10',14',16',22'-tetraen-2'-one is found in Streptomyces hygroscopicus.

Based on a literature review very few articles have been published on Milbemycin D (PMID: 28095865).
