Ursodeoxycholic acid (3α, 7β-dihydroxy-5β-bile acid (UDCA) is a kind of dihydroxy acid, accounting for 3% of the total human bile. It Was first isolated from the bile of Chinabear and named by Shoda of Okayama University inJapan, in 1985 Leuschner found that the serum transaminases decreased when he treated Combined hepatitis gallstones by it, after then a large number of clinical studies have proved that UDCA has real treatment effects on some liver disease. Its therapeutic mechanism of action and efficacy on liver disease are as below:

Cholestatic liver disease has close relation with the accumulation of chenodeoxycholic acid, deoxycholic acid and lithocholic acid, these cholalic acid will cause liver cell damage due to the detergent function. UDCA is a kind of non-toxic hydrophilic cholalic acid which can competitively inhibit the absorption of toxic endogenous cholalic acid in the ileum. By activating signal network composed of calcium ions and protein kinase C and mitotic activity of protein kinase it can enhance the secretory capacity of cholestatic liver cells and decrease the concentration of endogenous hydrophobic bile acid in the blood and liver cells to attain the effect of anti cholestatic. UDCA also can competitively take place of toxic cholic acid molecules in the cell membranes and cell wall to prevent the toxic cholic acid from more damage to hepatocytes and biliary cells. The specific performance of these effects are as followed:

(1) Cytoprotective effect. UDCA bonder can significantly reduce cell lysis of liver cell which is induced by hydrophobic cholalic acid and decrease the apoptosis of cultured rat and human which is induced by toxic cholalic acid.
(2) Membrane stabilizing effect. UDCA can prevents mitochondrial membrane from permeability changes induced by cholalic acid. In other words, it can use the membrane stabilizing function to protect mitochondrial membrane, basement membrane and small duct membrane from damage induced by cholalic acid.
(3) Antioxidant effect. UDCA can inhibit activation of cell Kupffer induced by toxic cholalic acids, It also can increase the level of glutathione and thiol-containing proteins in liver cells to protect liver cells from oxidative damage.
(4) Immunoregulation effects. UDCA can indirectly inhibit the typeⅠand type Ⅱ gene expression of major histocompatibility complex (MHC) by reducing stimulation of hydrophobic cholalic acid , it also can directly inhibit the gene expression by activating the glucocorticoid receptor.

1. NAD (Nicotinamide adenine dinucleotide) product
Synonym: NAD+, Co I, Nicotinamide adenine dinucleotide
CAS:53-84-9
Molecular weight: 662.42
Normal package:1kg,10kg

2. product information:
1) NAD is a kind of coenzyme existed in all living cells, it is an essential coenzyme in modern biocatalysis.
2) NAD involves oxidation reduction reactions in organism, it transports and deliver the substance in the reaction, transfer of electrons; bioconversion reaction.
3) NAD can be used as a direct template for drug design, it also can indirectly change the activity of action on enzyme by designing enzyme inhibitors or stimulants based on the structure of NAD, or it can directly inhibit the biosynthesis of NAD.
4) NAD is possibly to become to be a very important anti-aging ancillary drug. The hot product Sir2 protein in modern biological research is just a deacetylase enzyme relying on NAD, which main function is to prolong life cycle of cell (anti-aging).
