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.

Octyl gallate (3,4,5-trihydroxybenzoate) was found to possess antifungal activity against Saccharomyces cerevisiae and Zygosaccharomyces bailii, in addition to its potent antioxidant activity. Catechol moiety is essential to elicit this activity. The primary fungicidal activity of octyl gallate comes from its
