| Common Name | 6-ethyl-8',9'-dihydroxy-10'-(hydroxymethyl)-7'-methoxy-5,6',14',16'-tetramethyl-2',20'-dioxaspiro[oxane-2,21'-tricyclo[17.3.1.0⁴,⁹]tricosane]-5',10',12',16'-tetraen-3'-one |

| Description | 6-Ethyl-8',9'-dihydroxy-10'-(hydroxymethyl)-7'-methoxy-5,6',14',16'-tetramethyl-2',20'-dioxaspiro[oxane-2,21'-tricyclo[17.3.1.0⁴,⁹]Tricosane]-5',10',12',16'-tetraen-3'-one 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. 6-ethyl-8',9'-dihydroxy-10'-(hydroxymethyl)-7'-methoxy-5,6',14',16'-tetramethyl-2',20'-dioxaspiro[oxane-2,21'-tricyclo[17.3.1.0⁴,⁹]tricosane]-5',10',12',16'-tetraen-3'-one is found in Streptomyces hygroscopicus. 6-Ethyl-8',9'-dihydroxy-10'-(hydroxymethyl)-7'-methoxy-5,6',14',16'-tetramethyl-2',20'-dioxaspiro[oxane-2,21'-tricyclo[17.3.1.0⁴,⁹]Tricosane]-5',10',12',16'-tetraen-3'-one is an extremely weak basic (essentially neutral) compound (based on its pKa). |
