Clinically it is used to treat disseminated sclerosis, porphyria, itching, liver disease, varicose ulcer complication. Eye drops with denosine monophosphate as the main component can be used to treat eye fatigue, central amphiblestitis, ocular pannus, herpes and other corneal surface diseases. Intramuscular injection shows local erythema, generalized essential telangiectasia, red face, dizziness, breathing difficulty and palpitation.
As nutrition enhancer; as intermediate to produce nucleotide drugs; as food additive; as biological products; as dietary supplement and biochemical reagent. It is used to produce adenosine triphosphate (ATP), cyclic adenylate (cAMP) and other biochemical drugs. It is a type of nucleotide products and to produce antiviral drugs, synthetic energy drugs and cardiovascular and cerebrovascular drugs, such as adenosine, ATP, 3 '-5'-cyclic adenosine monophosphate.
Preparation
Candida utilis fungi is treated with hot water to obtain nucleic acids, which is hydrolyzed by enzymes and separated to obtain the final product.
Take mycelia as the raw material:
Subtraction and sedimentation of mycelia are carried out with 3 times amount of water. Industry base is added to reach a base concentration of 0.25% (g/100mL). After stirring for 1 hours, 20% sulfuric acid is added until the PH value is 7. The solution is filtrated and the pH value of filtrate is adjusted with 20% sulfuric acid to 2.5. Centrifugation is then applied to obtain nucleic acid mud.
mycelia [sodium hydroxide]→[1h] extract solution [20% sulfuric acid] → [pH=7, filtration] filtrate [20% sulfuric acid] →[pH=2.5, centrifugation] nucleic acid mud
1% nucleic acid solution is made by subsequent dissolution, enzymolysis, absorption and elution. 10% ammonia water is then used to adjust the pH value to 6-6.2. Then the mixture is heated at 90°C for 20 min and cooled. After centrifugation, the supernatant is heated up to 65-70°C and added with 1/3 phosphodiesterase solution. After 2 hours, the temperature is raised to 90°C. 10min later, it is cooled to room temperature. 20% sulfuric acid is added to adjust the pH value to 2.5-3. After filtration, the filtrate is adjusted with ammonia solution until the pH=7.2-7.5. 0.3% (3 g/L) diatomite is then added to assist the filtration. The corresponding supernatant is filtered with an anion exchange resin column (717-type) and eluted with 0.05 mol/L sulfuric acid. Afterwards, absorption, elution and crystallization are carried out. The detailed procedures of these three steps are:
The eluate is first absorbed with a cation exchange column (732-type) and eluted with distilled water (pH=1.5). The collection of eluate starts when the eluate turned red with bromine water. The eluate is then concentrated to 80-90 mg/mL under reduced pressure, added with diatomite and stirred for 30 min before filtration. The filtrate is adjusted with 6 mol/L hydrochloric acid till pH=2.5. To realize full crystallization, the filtrate is cooled during stirring. After followed filtration, it is washed with dry ethanol for 3 times. Vacuum drying at 60°C is applied to obtain the final AMP products.

Description
Adenosine-5'-monophosphoric acid is a nucleotide that is synthesized from adenosine triphosphate and inosine monophosphate. Adenosine-5'-monophosphoric acid is an important molecule in the body because it is a substrate for cyclic AMP, which regulates many cellular processes. Adenosine-5'-monophosphoric acid also has biochemical properties that are similar to those of the neurotransmitter serotonin and it can activate the 5-HT2 receptors.
Chemical Properties
colorless to white crystalline powder
Uses
Adenosine 5'-Monophosphate is a natural occurring nucleotide and a useful ligand determinant that facilitate the binding of APS reductase inhibitors and activates adenosine receptor agonists.
