Aims:Present report describes the in vitro antimalarial activity and docking analysis of seven 4-aminoquinoline-clubbed 1,3,5-triazine derivatives on pf-DHFR-TS.Methods and Results:The antimalarial activity was evaluated in vitro against chloroquine-sensitive 3D7 strain of Plasmodium falciparum. Compounds were docked onto the active site of pf-DHFR-TS using docking server to explicate necessary structural requirements for antimalarial activity.Conclusion:Title molecules demonstrated considerable bioactivity against the malaria parasite. Docking analysis revealed deep engulfment of the molecules into the inner groove of pf-DHFR-TS active site by making stable ligand–receptor posses. Hydrophobic interaction was identified as the only major interacting force playing a role between ligand–receptor interaction and minor with hydrogen bonds.Significance and Impact of the study:The study provided the novel insight into the necessary structural requirement for rationale-based antimalarial drug discovery.
