1. Inosine (CAS: 58-63-9), as a nucleoside product, is mainly used to produce drugs for the treatment of viral infections and other diseases
2. Inosine is a non-canonical nucleotide majorly present as monophosphate. It has ability to base pair with deoxythymidine, deoxyadenosine and deoxyguanosine. Incorporation of inosine in place of guanine modulates translational events. Inosine has antioxidant, anti-inflammatory and neuroprotective functionality. Inosine is prescribed as a therapeutic supplement for nerve injury, inflammation and oxidative stress. It modulates biological processes through adenosine receptors. Its enhances neurite outgrowth in depressive disorders via adenosine receptors. Inosine is also used for treating sepsis in infections.
3. Inosine is the important material of human body, a kind of coenzyme drug widely used in the medicine and the food industry. It can penetrate cell membrane into the cell of body directly, and make the cell in a state of feeblemindedness and anoxia continue to metabolize smoothly. And it can activate caetone acid oxides, and participate the body protein in synthesizing.
Applications of Inosine pharmaceuticals, such as Inosine Tablets and Inosine Injection
1. Used in the treatment of leucopenia and thrombocytopenia.
2. In the treatment of acute hepatitis and chronic hepatitis and liver cirrhosis, hepatic encephalopathy.
3. Used for coronary atherosclerotic heart disease (coronary heart disease), myocardial infarction, rheumatic heart disease, cor pulmonale auxiliary drug use.
4. Used to prevent and mitigate the schistosomiasis prevention drugs caused by the heart and the liver toxicity.
5. Used for eye diseases (central retinal inflammation, optic atrophy) auxiliary drug use.
