Common NameAvermectin B2a
DescriptionAvermectin 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.
