Natural products present an opportunity to identify novel anti-mitotic compounds to address the lack of known inhibitors for many mitotic regulatory proteins. By biology-guided fractionation, we purified the natural products anemonin from Pulsatilla nuttalliana and (+)-6-tuliposide A from Erythronium grandiflorum, and this is the first report of their anti-mitotic activities.

The discovery of natural product inhibitors from Canadian prairie plant species holds tremendous potential for advancing our understanding of mitotic regulation and contributes to the development of targeted treatments for precision medicine.","abstract_html":"This thesis investigates Canadian prairie plants as sources of natural product compounds capable of inhibiting human cell division.
