Description

Milbemycin Beta11 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's,2r,4'r,5s,6r,7'r,8'r,9's,10'e,12'e,14'r,16'e,19'r)-7',8',9'-trihydroxy-5,6,6',10',14',16'-hexamethyl-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. Based on a literature review a small amount of articles have been published on Milbemycin Beta11.

Chemical Taxonomy

Description

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.
