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). Octyl gallate, an alkyl gallate, is reported to exhibit direct antibacterial activity against Staphylococcus aureus BB568. 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.

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.
