Aldéhydes

3,4-Dichlorobenzaldehyde oxime is a natural carotenoid that has been shown to have antibacterial activity. 3,4-Dichlorobenzaldehyde oxime is produced by the reaction of malonate and aldehyde in an incubated system. This compound has been shown to be active against Gram-positive bacteria such as staphylococcus and aldoximes and Gram-negative bacteria such as E. coli, Salmonella typhimurium, and Shigella flexneri. 3,4-Dichlorobenzaldehyde oxime inhibits bacterial growth by binding to the 50S ribosomal subunit of the bacterial cell membrane. This binding prevents protein synthesis, leading to cell death. The biosynthesis of 3,4-dichlorobenzaldehyde oxime involves the conversion of abscisic acid (ABA) into ABA quinone through oxidation by an enzyme called ABA oxidase
