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.

Compared to quinolines, isoquinolines are also prominent structural motifs present in many biologically significant natural and synthetic compounds. Some well-known isoquinoline alkaloids include the anticancer and anticonvulsant berberine, the vasodilator and antispasmodic drugs papaverine and emetine. In addition to naturally occurring isoquinolines, synthetic analogs have also shown significant biological activity.
