Novel halogenated arylvinyl-1,2,4 trioxanes as potent antiplasmodial as well as anticancer agents: Synthesis, bioevaluation, structure-activity relationship and in-silico studies.

Abstract Herein, we have synthesized a series of lipophilic, halogenated-arylvinyl-1,2,4-trioxanes 8a–g (28 compounds) and assessed for their in vitro anti-plasmodial activity in Plasmodium falciparum culture using SYBRgreen-I fluorescence assay against chloroquine-resistant Pf INDO and artemisinin-resistant Pf Cam 3.1R539T (MRA-1240) strains. Alongside, the cell cytotoxic potential of 8a–g has also been determined against the HEK293 cell line in vitro. Out of twenty-eight halogenated-arylvinyl-1,2,4-trioxanes; ten analogues (8a2, 8a4, 8b2, 8b4, 8d4, 8e1, 8e2, 8e4, 8f2, and 8g4) have shown potent in vitro antiplasmodial activity with IC50  1M17 ) have demonstrated the strong virtual interaction.
