Cytosine

Cytosine, scientific name 4-amino-2-carbonylpyrimidine, is an organic compound with the molecular formula C4H5N3O. It is one of the main base components in nucleic acids (DNA and RNA). Cytosine can be synthesized from dimethyl uracil, and chloroacetic acid as raw materials. Used as a pharmaceutical intermediate.

Abbreviated as C. One of the pyrimidine type bases in nucleic acid. It exists in DNA and RNA. In plant DNA, in addition to cytosine, there is also a small amount of 5-methylcytosine. In the double helix of DNA, cytosine on one strand pairs with guanine on the other strand, forming three hydrogen bonds between molecules. This hydrogen bond between base complementary pairs is one of the important forces for the stability of DNA double helix. Cytosine nucleoside and cytosine nucleotide can both be used as drugs to elevate white blood cells. It can be synthesized from dimethyl uracil, and chloroacetic acid as raw materials.

Cytosine is an important intermediate in fine chemicals, pesticides and medicines, and has a wide range of applications.
1. In pesticides, the first new cytosine peptide type antibiotic was discovered. It is a high-efficiency, low-toxicity, and low-residue broad-spectrum agricultural antibiotic Chemicalbook.
2. In the field of medicine, cytosine is a nucleic acid substance that can be used as an antiviral drug. It is mainly used to synthesize anti-AIDS drugs and anti-hepatitis B drugs lamivudine, anti-cancer drugs gemcitabine, and 5- Flucytosine and so on.

Cytosine nucleosides and cytosine nucleotides can be used as drugs for raising white blood cells. Cytosine is an important intermediate in fine chemicals, pesticides and medicines, especially in the field of medicine. It is mainly used in the synthesis of anti-AIDS drugs and anti-hepatitis B drugs lamivudine, anticancer drugs gemcitabine, enoxabine and 5- Fluorocytosine, etc., is widely used.

Cytosine is an important intermediate in fine chemicals, pesticides and medicines, and has a wide range of applications.

Cytosine is one of the four main bases found in DNA and RNA, alongwith adenine, guanine, and thymine (uracil in RNA).Cytosine reagent is used in a wide variety of research applications, as anenzyme substrate or precursor of effector molecules such as cytosine sugars.
