  • Publication number: 20100003346
    Abstract: The present invention relates to compositions and methods for treating cancer, by administering a combination comprising a jasmonate derivative (e.g., methyl jasmonate or a compound of any of formulae I through VII or any of the jasmonate derivatives exemplified by such formulae) and at least one other agent selected from a chemotherapeutic agent (e.g., a nitroso-urea, a platinum compound, a taxane derivative, an antitumor antibiotic) and an inhibitor of glycolysis (e.g., 2-deoxy-D-glucose). The jasmonate derivative and the at least one other agent together provide a therapeutic effect, which is preferably synergistic (cooperative).
