Aromatic (heterocyclic) compounds are carbon or heterocyclic compounds characterized by their aromatic structures, which consist of closed conjugated systems.
Incorporating aromatic (heterocyclic) functional groups into drug molecules can result in a wide range of interactions with biological targets, leading to diverse biological activities and selectivity, ultimately achieving various therapeutic effects.
Aromatic (heterocyclic) compounds play a pivotal role in the development of small molecule drugs, with more than 90% of currently available drugs containing these aromatic (heterocyclic) rings.
