General description
Octyl gallate (3,4,5-trihydroxybenzoate) is reported to possess antifungal activity against Saccharomyces cerevisiae and Zygosaccharomyces bailii. The fungicidal activity associated with octyl gallate is due to its ability to act as a nonionic surface-active agent (surfactant).[1] Octyl gallate, an alkyl gallate, is reported to exhibit direct antibacterial activity against Staphylococcus aureus BB568.[2] It is reported to inhibit the activity of soybean lipoxygenase-1 (EC 1.13.11.12, type I) with an IC50 of 1.3μM. It is also effective in preventing lipid peroxidation.[3]
Application
Octyl gallate was used in a study to investigate the self-assembly in two comb-shaped supramolecules systems consisting of octyl gallate, hydrogen bonded to the pyridine groups of polyisoprene-block-poly(vinylpyridine) diblock copolymers using synchrotron radiation.

Octyl gallate inhibited soybean lipoxygenase-1 (EC 1.13.11.12, type I) with an IC(50) of 1.3 microM. The inhibition of the enzyme by octyl gallate is a slow and reversible reaction without residual activity. The inhibition kinetics analyzed by Lineweaver-Burk plots indicates

The plastid terminal oxidase (PTOX) encoded by the Arabidopsis IMMUTANS gene was expressed in Escherichia coli cells and its quinone/oxygen oxidoreductase activity monitored in isolated bacterial membranes using NADH as an electron donor. Specificity for plastoquinone was observed. Neither ubiquinone
