Oxidative stress, a result of an overproduction and accumulation of free radicals, is the leading cause of several degenerative diseases such as cancer, atherosclerosis, cardiovascular diseases, ageing and inflammatory diseases. 2020 Dec;58(1):590-596. doi: 10.1080/13880209.2020.1777169. Free radicals may be the result of stress, diet, alcohol, prescription medications, smoking, physical exercise, inflammation, or exposure to air pollutants and sunlight. In this current study, the effects of GA on mushroom tyrosinase, tyrosinase inhibitory activity, and melanin content were assessed in B16 melanoma cells (B16 cells). Gallic acid (A) had the highest antioxidant capacity with 61% RSA, followed by protocatechuic acid (B), 35% RSA; chlorogenic acid (C), 28% RSA and vanillic acid had the lowest value of 11% RSA. Based on these results, I propose that GA exerts antimelanogenic activity coupled with antioxidant properties by suppressing RS generation and maintaining a higher GSH/GSSG ratio. USA.gov.
