Conjugation of vitamin E analog α-TOS to Pt(iv) complexes for dual-targeting anticancer therapy

We report two platinum(IV) complexes conjugated with a vitamin E analog, α-tocopherol succinate (α-TOS). One of the conjugates displays the activity of both cisplatin and α-TOS in cancer cells, causing damage to DNA and mitochondria simultaneously. Accordingly, it serves as a promising dual-targeting anticancer agent.
