D-Saccharic Acid 1,4-lactone (hydrate)

D-Saccharic Acid 1,4-lactone (hydrate) (CAS No.: 61278-30-6) is a small-molecule carbohydrate-derived lactone widely utilized in biomedical research as a selective inhibitor of β-glucuronidase, an enzyme involved in the hydrolysis of glucuronide conjugates and the regulation of xenobiotic metabolism and cellular signaling processes. By targeting β-glucuronidase, this compound modulates enzyme activity with inhibitory potency in the low micromolar range, enabling effective interference with glucuronide turnover and associated biochemical pathways. It is commonly employed as a reference standard in the development and evaluation of novel β-glucuronidase inhibitors, as well as a stabilizing agent to prevent enzymatic degradation of glucuronides in biological samples such as plasma, serum, and urine. Functionally, D-saccharic acid 1,4-lactone (hydrate) has been associated with anticarcinogenic, detoxifying, and antioxidant effects, supporting its relevance in cancer biology, toxicology, and oxidative stress research. In experimental settings, it is applied across cell-based and in vivo models to investigate enzyme-mediated metabolic processes and signaling alterations, with concentrations or dosing regimens adjusted according to specific study designs and therapeutic hypotheses.
