New methods for preparing analogues of qinghaosu (QHS, or artemisinin) and synthetic trioxane derivatives are developed. These new derivatives which have attached DNA-ligating groups are capable of aligning the trioxane nucleus proximate to specified base sequences in DNA. Despite the idea of combin.....
