To find novel skin-whitening agents, the melanogenesis inhibitory action of gallic acid (GA) was investigated. Gallic acid acts as a antioxidant and helps to protect our cells against oxidative damage. Corresponding authors, a 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).

Barua N, Ibn Aziz MA, Tareq AM, Sayeed MA, Alam N, Alam NU, Uddin MA, Lyzu C, Emran TB. Gallic acid is a trihydroxybenzoic acid found in many plants as either the free acid or in the esterified form of gallotannins and ellagitannins. HHS It has a role as an astringent, a cyclooxygenase 2 inhibitor, a plant metabolite, an antioxidant, an antineoplastic agent, a human xenobiotic metabolite, an EC 1.13.11.33 ( arachidonate 15-lipoxygenase) inhibitor and an apoptosis inducer. The Gallic acid can also be used as a starting material in the synthesis of the psychedelic alkaloid mescaline. To investigate the relation between GA's inhibition of melanogenesis and antioxidant activity, the effect of GA on reactive species (RS) generation and the reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio in were determined in B16 cells. This invention relates to additives for methanesulfonic acid based tin and tin alloy plating formulations. Fetching data from CrossRef.

ORAC (Oxygen Radical Absorbance Capacity) ORAC (Oxygen Radical Absorbance Capacity) values are a measure of the antioxidant activity. 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. contained in this article in third party publications it in a third party non-RSC publication you must eCollection 2020. To find novel skin-whitening agents, the melanogenesis inhibitory action of gallic acid (GA) was investigated.

Journal of Agricultural and Food Chemistry 2013 , 61 (26) , 6533-6543. lic acid (GA, 3,4,5-trihydroxybenzoic acid) is a naturally oc-curring polyphenol antioxidant that was recently shown to have potentially healthy effects16); however, the inhibitory action of GA on skin melanogenesis has not been fully explored. J-STAGE, Japan Science and Technology Information Aggregator, Electronic. Would you like email updates of new search results? Apart from its phytochemical role, gallic acid is also used in tanning, ink dyes, and the manufacture of paper. Among various polyphenols, gallic acid (3,4,5-trihydroxybenzoic acid), a naturally occurring low molecular weight triphenolic compound, has emerged as a strong antioxidant and an efficient apoptosis inducing agent. Our results are similar to those reported by Rice-Evans et al. XX is the XXth reference in the list of references. Gallic acid derivatives have also been found in a number of phytomedicines with diverse biological and pharmacological activities, including radical scavenging, interfering with the cell signaling pathways and apoptosis of cancer cells.
