4-anilinoquinoline triazines: a novel class of hybrid antimalarial agents.

Abstract A novel class of hybrid 4-anilinoquinoline triazines have been synthesized and evaluated in vitro for their antimalarial activity against CQ-sensitive 3D7 strain of P. falciparum as well as for their cytotoxicity toward VERO cell line. Five compounds ( 19 , 20 , 23 , 41 and 45 ) exhibited the antimalarial potency superior to CQ. Compounds 14 and 16 were found to be orally active at a dose of 100 mg/kg × 4 days against CQ-resistant strain of P. yoelii . Inhibition of β-hematin formation assay and molecular docking study has been conducted in order to gain insight into the mechanism of action of proposed targets for the 4-anilinoquinoline and triazine moiety of the hybrid compounds.
