Pyridine and Pyrimidine hybrids as privileged scaffolds in antimalarial drug discovery: A recent development

Malaria continues to pose a significant threat to global health, which is exacerbated by the emergence of drug-resistant strains, necessitating the urgent development of new therapeutic options. Due to their substantial bioactivity in treating malaria, pyridine and pyrimidine have become the focal point of drug research. Hybrids of pyridine and pyrimidine offer a novel and promising avenue for developing effective antimalarial agents. The ability of these hybrids to overcome drug resistance is tinted, offering a potential solution to this critical obstacle in the treatment of malaria. By targeting multiple pathways, these hybrid compounds reduce the likelihood of resistance development, providing a promising strategy for combating drug-resistant strains of malaria. The review focuses on the most recent developments in 2018 in the structural optimization of pyridine and pyrimidine hybrid compounds, highlighting modifications that have been shown to improve antimalarial activity. Structure-activity studies have elucidated the essential characteristics required for potency, selectivity, and pharmacokinetics. Molecular docking and virtual screening expedite the identification of novel compounds with enhanced activity profiles. This analysis could aid in developing the most effective pyridine and pyrimidine hybrids as antimalarial agents.
