Pyrimidine, also known as 1,3-diazobenzene, is a heterocyclic compound with the chemical formula C4H4N2. Pyrimidine is formed by substituting 2 nitrogen atoms for 2 carbons in the meta-position of benzene. It is a diazine and retains its aromaticity. Derivatives of pyrimidine widely exist in organic macromolecular nucleic acids, and many drugs also contain pyrimidine rings. In nucleic acids, three nucleobases are pyrimidine derivatives: cytosine, thymine and uracil. There are a variety of pyrimidine-containing drugs on the market, most of which are kinase inhibitors.
Azaindole can be regarded as the biological isostere of indole, and the molecular unit of indole plays a huge role in the life process. Many drug molecules contain indole units. Azaindole is an important heterocyclic intermediate with good biological and medicinal value, and is the core structure of many drugs, such as antitumor drugs, dopamine D4 receptors, kinase inhibitors, thrombin inhibitors, etc. Therefore, it has a wide range of application value in medical research.
