Abstract Aldoses in alkaline medium under the catalytic action of platinum or rhodium are converted into aldonic acids with high selectivity and with concomitant evolution of hydrogen gas. The dehydrogenation reaction has been studied for 25 different mono- and di-saccharides, and is generally applicable for reducingsugars. The influence of several reaction variables has been studied, leading to an

The reaction of dimethyl squarate with aminodeoxy sugars, aminodeoxy alditols, amino aldonic acids, and glycosyl amines under neutral conditions furnished the squaric amide esters, which were converted in more alkaline media (pH ≈8) into the asymmetric squaric diamides. The unprotected squaric acid amide esters are suitable for constructing a specific anchor (spacer, linker) function that favorably influences the water-solubility of the resulting drugs and glycoconjugates.

Bileacid signaling and metabolism in the gastrointestinal tract have wide-ranging influences on systemic disease. G protein-coupled bileacidreceptor 1 (GPBAR1, TGR5) is one of the major effectors in bileacid sensing, with demonstrated influence on metabolic, inflammatory, and proliferative processes. The pharmacologic utility of TGR5agonists has been limited by systemic target-related effects

The kinetic behaviour and relative reactivities of some carbohydrates (aldoses, amino sugars and methylated sugars) towards platinum(IV) in alkalinemedium have been investigated. The reactions are first order with respect to [substrate] and Pt IV . The rates increase with the increase in OH − . The reactions show pseudo-first-order dependence on OH − . The oxidation rates in alkalinemedium follow the
