Cytosine, the scientific name is 2-carbonyl-4-aminopyrimidine, the CAS number is 71-30-7, and the molecular formula is C4H5N3O. One of the main base components in nucleic acids (DNA and RNA). Cytosine can be synthesized from dimercaptouracil, concentrated ammonia and chloroacetic acid as raw materials. Used as a drug intermediate.

　　The abbreviation for Glutataione, and there is a noun to explain GSH. Melitin GSH is a special substance for detoxification. It is a small molecule peptide composed of three amino acids. It acts as an important antioxidant and free radical scavenger in the body, such as combining with free radicals, heavy metals, etc., thereby reducing the body The harmful poison is transformed into harmless substances and excreted from the body

　　Vitamin B4 (Vitamin B4; Adenine) is the old name for adenine, which is no longer regarded as a real vitamin, and is no longer a member of vitamin B. Molecular formula: C5H5N5 Molecular weight: 135.127 Its properties are: white needle-like crystals. It begins to sublime at 220°C and decomposes at 360-365°C. Soluble in acid and alkali, slightly soluble in alcohol, insoluble in ether and chloroform. The aqueous solution is neutral. Has a strong salty taste. It is obtained by ammoniating 4,6-dichloro-5-nitropyrimidine with ammonia to obtain 4,6-diamino-5-nitropyrimidine, which is then cyclized with formic acid, formamide and sodium thiosulfate. Mainly used to participate in the synthesis of DNA and RNA, for leukopenia caused by radiotherapy, benzene poisoning and anti-tumor, for acute neutropenia, medicine and biochemical research
