In vitro and in vivo antifilarial activity evaluation of 3,6-epoxy [1,5]dioxocines: A new class of antifilarial agents

A series of 3,6-epoxy [1,5]dioxocines were synthesized and evaluated for their antifilarial activity against adult parasites of human lymphatic filarial parasite Brugia malayi (sub-periodic strain) in vitro. Out of these, six compounds (4a–f) possessed improved in vitro anti-filarial activity and examples 4d and 4f were also found to be active in the in vivo experiments. These results demonstrate that 3,6-epoxy [1,5]dioxocines exhibits potent antifilarial activity and might be developed into a new class of antifilarial drug.

The discovery of 3,6-epoxy [1,5]dioxocines as potential antifilarial agents is described. The most active compound 4f showed promising in vitro as well as in vivo antifilarial activity.Figure optionsDownload as PowerPoint slide
