Description3,21',24'-trihydroxy-5,6,11',13',22'-pentamethyl-2'-oxo-3',7',19'-trioxaspiro[oxane-2,6'-tetracyclo[15.6.1.1⁴,⁸.0²⁰,²⁴]pentacosane]-10',14',16',22'-tetraen-4-yl 2-methylhexanoate 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. 3,21',24'-trihydroxy-5,6,11',13',22'-pentamethyl-2'-oxo-3',7',19'-trioxaspiro[oxane-2,6'-tetracyclo[15.6.1.1⁴,⁸.0²⁰,²⁴]pentacosane]-10',14',16',22'-tetraen-4-yl 2-methylhexanoate is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Milbemycin alpha5 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Milbemycin alpha5 is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
