Studies on Uric Acid and Related Compounds
The systematic study of the substrate specificity of mammalian xanthine oxidase has indicated a common mechanism by which various purines may be dehydrogenated (1). The results obtained also made it clear why methylated xanthines, with the exception of 1-methylxanthine (2), cannot be oxidized by xanthine oxidase to the corresponding substituted uric acids (3, 4). Therefore, another source had t...
متن کاملKojic Acid Derivatives
Melanin is one of the most important pigments which exist ubiquitously from microorganisms to plants and animals. It is secreted by melanocyte cells and determines the color of skin and hair in mammalians. It protects the skin from photocarcinogenesis by absorbing UV sunlight and removing reactive oxygen species (ROS) (Gupta, 2006; Kim, 2005; Sapkota, 2011). It is formed by enzymatically cataly...
متن کاملStudies on uric acid and related compounds. I. Quantitative determination of uric acid in biological fluids.
The available methods of determination of uric acid can be divided into three main groups: (a) the direct determination of the reducing power of uric acid; (b) the coprecipitation of the uric acid or its adsorption on a precipitating material, dissolving the acid, and determination of its reducing power; and (c) quantitative decomposition of uric acid by uricase. A survey of these methods has b...
متن کاملCombined kinetic studies and computational analysis on kojic acid analogous as tyrosinase inhibitors.
Tyrosinase is a key enzyme in melanin synthesis and widely distributed in plants and animals tissues. In mammals, this enzyme is related to pigment production, involved in wound healing, primary immune response and it can also contribute to catecholamines synthesis in the brain. Consequently, tyrosinase enzyme represents an attractive and selective target in the field of the medicine, cosmetics...
متن کاملIn vitro and in silico studies of the inhibitory effects of some novel kojic acid derivatives on tyrosinase enzyme
Objective(s): Tyrosinase is a key enzyme in pigment synthesis. Overproduction of melanin in parts of the skin results in hyperpigmentation diseases. This enzyme is also responsible for the enzymatic browning in fruits and vegetables. Thus, its inhibitors are of great importance in the medical, cosmetic and agricultural fields. Materials and Methods: A series of twelve kojic acid derivatives wer...
