Oganomycin GB

Oganomycin GB is derived from the bacterium Streptomyces (Streptomyces str. oganonensis YG 19Z) . When sodium para-hydroxycinnamate is added to the fermentation medium, Oganomycin A is produced. This compound is converted into its glutaric acid derivative, Oganomycin GA, via the action of D-amino acid oxidase. After the removal of sulfate ester through acidic hydrolysis, both A and GA yield Oganomycin B and Oganomycin GB. The effectiveness of Oganomycin GB is greater against Gram-negative bacteria compared to Gram-positive bacteria.
