Description:
Cytosine is one of the major base components of nucleic acids (DNA and RNA). Cytosine can be synthesized from dithiol uracil, concentrated ammonia and chloroacetic acid. Used as a drug intermediate.
Cytosine is found in DNA and RNA. In plant DNA, in addition to cytosine, there is a small amount of 5-methylcytosine. In the double helix of DNA, cytosine on one strand pairs with guanine on the other, forming three hydrogen bonds between the molecules. The hydrogen bond between these complementary pairs is one of the important forces for the stability of DNA double helix structure. Cytosine nucleoside and cytosine nucleotide can both be used as drugs to elevate white blood cells. It can be synthesized from dithiol uracil, concentrated ammonia and chloroacetic acid.
Cytosine nucleoside and cytosine nucleotide can both be used as drugs to elevate white blood cells. Cytosine is an important intermediate in fine chemical industry, pesticide and medicine, especially in the field of medicine. It is mainly used in the synthesis of anti-aids drugs and anti-hepatitis b drugs lamivudine, anti-cancer drugs gemcitabine, enoxabine and 5-fluorouracil. It is widely used.
