US Patent 7998938 Cancer treatment by combined inhibition of proteasome and telomerase activities

A method and kit for inhibiting the proliferation of cancer cells are disclosed, based on a combination of a proteasome inhibitor and a telomerase inhibitor. When used in cancer therapy, the two compounds in combination enhance the anti-cancer treatment efficacy obtained with the proteasome inhibitor alone or the telomerase inhibitor alone. Preferably, efficacy is supraadditive or synergistic in nature relative to the combined effects of the individual agents, with minimal exacerbation of side effects.
