Abstract
Objectives: Malaria continues to be the primary cause of mortality worldwide, and timely recognition and prompt intervention are crucial in mitigating adverse consequences. This review article aims to examine the effectiveness and structural characteristics of quinoline-based compounds as antimalarial agents. It specifically focuses on their therapeutic effects as well as potential prospects for exploring structure-activity relationship (SAR). In addition, this study aims to identify lead compounds that can efficiently battle multidrug-resistant forms of Plasmodium falciparum and Plasmodium vivax. Methods: A comprehensive review was conducted to evaluate the effectiveness of quinoline-based antimalarial medications in eradicating P. falciparum and P. vivax. The mechanism of action and SAR of these compounds were analyzed Results: Quinoline-based antimalarials demonstrated significant effectiveness in eliminating P. falciparum parasites, particularly in regions severely impacted by malaria, including Africa and Asia. These compounds were found to exhibit tolerance and immune-modulating properties, indicating their potential for more widespread utilization. The investigation identified various new quinoline compounds with improved antimalarial activity, including metal-chloroquine complexes, diaminealkyne chloroquines, and cinnamoylated chloroquine hybrids. This study explored different mechanisms by which these compounds interact with parasites, including their ability to accumulate in the parasite’s acidic food vacuoles and disrupt heme detoxification. The derivatives demonstrated strong efficacy against chloroquine-resistant strains and yielded positive results. Conclusion: Quinoline-based compounds represent a promising avenue for combating malaria due to their demonstrated efficacy against P. falciparum and P. vivax parasites. Further research on their mechanisms of action and SAR could lead to the development of more effective antimalarial medications.
