Description

Avermectin B2a is a member of the avermectin class of compounds, which are macrocyclic lactones produced by the fermentation of the bacterium Streptomyces avermitilis. This compound serves as a crucial starting material in the synthesis of various derivatives aimed at enhancing insecticidal properties. Recent studies have reported the synthesis of 23,24-alkene-avermectin B2a derivatives through a one-pot multistep reaction, highlighting its versatility in developing novel insecticidal agents (PMID:35584200 ). Additionally, three series of avermectin B2a oxime ester derivatives have been synthesized, demonstrating improved potency compared to the parent compound (PMID:35542930 ). Avermectin B2a has also been explored for its site-selective acylation, where organocatalytic methods have been employed to enhance the yield and selectivity of monoacylation at specific hydroxyl groups (PMID:27075247 ). These advancements indicate that avermectin B2a not only serves as an effective insecticidal and anti-parasitic drug but also as a valuable scaffold for the development of new derivatives with enhanced biological activity. The ongoing research into its derivatives underscores the potential for improving pest control strategies through chemical modifications.

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.
