Abstract: The quinolinic ring, present in several molecules, possesses a great diversity of biological
activities. Therefore, this ring is in the structural composition of several candidates of drugs in preclinical
and clinical studies; thus, it is necessary to compile these results to facilitate the design of
new drugs. For this reason, some of the activities of compounds are selected to examine in this review,
such as antimalarial, antimicrobial, anticancer, anti-inflammatory, antidiabetic, anti-rheumatic,
and antiviral activities. All publications of scientific articles chosen are dated between 2000 and 2020.
In addition to presenting the structures of some natural and synthetic compounds with their activities,
we have listed the clinical studies of phases III and IV on antimalarial drugs containing the quinoline
nucleus and phase III clinical studies on hydroxychloroquine and chloroquine to assess their possible
role in COVID-19. Finally, we have reviewed some of the mechanisms of action, as well as the side
effects of some of the quinolinic derivatives.
