bizelesin.

Melafolone is a natural dual inhibitor of cox-2 and egfr, improving program death 1 (pd-1) checkpoint blockade therapy through normalizing tumor vasculature and pd-l1 downregulation

Bizelesin is a synthetic cyclopropylpyrroloindole antineoplastic antibiotic. Bizelesin binds to the minor groove of DNA and induces interstrand cross-linking of DNA, thereby inhibiting DNA replication and RNA synthesis. Bizelesin also enhances p53 and p21 induction and triggers G2 M cell-cycle arrest, resulting in cell senescence without apoptosis.
