A new series of bis-1,2,4-trioxanes 12a-h, 13a-h, and 14a-h and tris-1,2,4-trioxanes 12i-14i were prepared and evaluated against multidrug-resistant Plasmodium yoelii in Swiss mice by oral route. Cyclopentane-based bis-trioxanes 12a, 12b, 12f-h and cyclohexane-based bis-trioxanes 13a, 13f, and 13g showed promising activity. All the tris-1,2,4-trioxanes were found to be inactive. Bis-trioxane 12a, the most active compound of the series, provided 100% and 80% protection to infected mice at 48 and 24 mg/kg x 4 days, respectively. Clinically useful drug P-arteether provided 100% and 20% protection at similar doses.
