Kojic 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 کاملDerivatives of Glucuronic Acid
The presence of glucuronic acid in the complex molecules of specific bacterial polysaccharides (1) has stimulated a study of certain derivatives of this important substance and its lactone, glucuron. These investigations have entailed the necessity of elaborating a satisfactory method for preparing both the acid and its lactone, and at the same time they have embraced a study of the comparative...
متن کاملMultifunctional Cinnamic Acid Derivatives.
Our research to discover potential new multitarget agents led to the synthesis of 10 novel derivatives of cinnamic acids and propranolol, atenolol, 1-adamantanol, naphth-1-ol, and (benzylamino) ethan-1-ol. The synthesized molecules were evaluated as trypsin, lipoxygenase and lipid peroxidation inhibitors and for their cytotoxicity. Compound 2b derived from phenoxyphenyl cinnamic acid and propra...
متن کاملEsters and Related Carboxylic Acid Derivatives
The ester functionality does not introduce a center of asymmetry and thus optical and geometric isomerism does not result from the presence of this functional group. The ester functionality (the carbonyl and ether oxygen) is composed of an sp hybridized carbon so it cannot be chiral, and since there is free rotation about the ether bond geometric isomerism also is not possible at the sp center....
متن کاملAmino derivatives of mannuronic acid.
The widespread occurrence of amino derivatives of the sugars in products of plant and animal origin suggests the possibility that amino derivatives of the uronic acids may likewise be of importance. The uronic acids have the characteristic structures of both aldoses and aldonic acids, and hence, like the aldoses, might be expected to yield glycosyl amines [1] and like the lactones of the aldoni...
