Résumé
Pyrrole [1,2-α] indole is a novel fused heterocyclic skeleton, which is also the basic structural unit and synthetic intermediate of many natural active products and drugs. Pyrrole [1,2-α] indole heterocyclic derivatives have attracted much attention in organic synthesis and medicinal chemistry because of their extensive and marked biological activities. Plant extracts have always been an important source of active compounds. At present, the alkaloids based on the pyrrole [1,2-α] indole heterocyclic structure discovered and isolated from plant extracts include isatisine, isoborreverine, flinderoles, polyavolensin and yuremamine. This paper reviews the research progress on the biological activity of pyrrole [1,2-α] indole heterocyclic derivatives and has found that pyrrole [1,2-α] indole heterocyclic derivatives have a good development prospect in screening active compounds and developing candidate drugs.
