葡萄糖二酸鈣,Calcium D-saccharate tetrahydrate

Calcium D-saccharate is the calcium salt of saccharic acid, also known as glucaric acid. Calcium D-saccharate has been evaluated for chemopreventive activity in a rat tracheal epithelial cell following exposure to the carcinogen benzo[a]pyrene. Addition of calcium D-saccharate to sugarcane juice during liming enhanced clarification as high molecular weight components were removed by filtration. 

Potent β-glucuronidase inhibitor. Stimulates differentiation and suppresses proliferation. Shows chemopreventive and antitumor effects in vivo. Orally active.

Calcium D-glucarate is the calcium salt form of D-glucaric acid. D-Glucaric acid is an end product of D-glucuronic acid metabolism in mammals that has also been found in fruits and vegetables and has anticancer activity. It is produced by the oxidation of D-glucuronic acid and is a precursor in the biosynthesis of the β-glucuronidase inhibitor D-glucaro-1,4-lactone (D-saccharic acid 1,4-lactone) in vivo. Dietary administration of calcium D-glucarate (10% w/w) reduces tumor growth in a rat model of mammary tumorigenesis induced by 7,12-dimethylbenz[a]anthracene (DMBA). Urinary D-glucaric acid levels have been used as a marker for xenobiotic-induced phase II metabolism in patients with rheumatoid arthritis or individuals exposed to environmental toxicants.

Calcium Saccharate is the calcium salt form of glucaric acid, a natural substance found in many fruits and vegetables, with potential anti-cancer property. One of the key processes in which the human body eliminates toxic chemicals as well as hormones (such as estrogen) is by attaching glucuronic acid to them in the liver and then excreting the complex in the bile. When beta-glucuronidase breaks the bond, it prolongs the stay of the hormone or toxic chemical in the body. Elevated beta-glucuronidase activity has been implicated to be associated with an increased risk for hormone-dependent cancers like breast, prostate, and colon cancers. Therefore, supplementing calcium glucarate may suppress the developments of hormone-dependent cancers.

A sugar acid derived from D-glucose in which both the aldehydic carbon atom and the carbon atom bearing the primary hydroxyl group are oxidized to carboxylic acid groups.
