A spermine-conjugated lipophilic Pt(iv) prodrug designed to eliminate cancer stem cells in ovarian cancer

We developed a spermine-conjugated lipophilic Pt(iv) prodrug that is able to reduce the cancer stem cell population in ovarian cancer. The therapeutic effect is attributed to the hydrophobic tail and cationic spermine head group, the combination of which allows the Pt(iv) prodrug to localize in mitochondria and induce corresponding damage.
