    摘要： 3-Substituted-.beta.-lapachone analogs and their use either alone or to augment chemotherapy or radiotherapy to induce programmed neoplastic cell death without exhibiting toxicity to surrounding normal cells are disclosed. In particular, 3-allyl-.beta.-lapachones, 3-alkyl-.beta.-lapachones and 3-halo-.beta.-lapachones were found to be Topoisomerase (Topo I) inhibitors. When these analogs are used alone there is a reversible single-strand break in the DNA of neoplastic cells causing apoptosis and cell death in some cells. However, when these analogs are combined with chemotherapy or X-irradiation, an irreversible Topo I-mediated break is achieved. A new and more efficient chemical synthesis of the compounds is also disclosed.

    摘要： The present invention relates to the inhibition of cancer cell growth, proliferation, and metastasis by contacting cells with an N,N'-dibenzyl .alpha.,.omega.-diaminoalkane, a derivative of naturally-occurring putrescine. More specifically, the present invention relates to the treatment of cancer in humans by administration of a cancer cell growth-inhibiting amount of an N,N'-dibenzyl .alpha.,.omega.-diaminoalkane to a human cancer patient.
