    Abstract: This invention relates to novel cancer treatment compositions and associated therapeutic methods. More particularly, this invention relates in part to small chemical bifunctional inhibitors of DNA replication and repair proteins Metnase and/or Intnase (also termed Gypsy Integrase, Gypsy Integrease-1, Gypsy Retransposon Integrase 1, or GIN-I) that simultaneously damage DNA, and to a therapeutic method that utilizes the inhibitors to increase the effectiveness of cancer treatment protocols, including radiation therapy. In preferred embodiments, compounds, compositions and methods of treatment of the invention are used to treat a patient suffering from leukemia (e.g. acute myeloid leukemia (AML) and related cancers. In certain aspects of such treatments, compounds, compositions and methods of treatment of the invention are administered as a monotherapy (in some cases, to patients who have exhibited resistance to Topo IIalpha inhibitors such as VP-16), or are co-administered with a Topo IIalpha inhibitor or other anti-cancer agents as otherwise described herein or in combination with radiation therapy.

    Abstract translation: 本发明涉及新的癌症治疗组合物和相关的治疗方法。 更具体地说，本发明部分涉及同时损伤DNA的DNA复制和修复蛋白质Metnase和/或Intnase（也称为Gypsy整合酶，Gypsy Integrease-1，Gypsy Retransposon Integrase 1或GIN-1）的小型化学双功能抑制剂， 以及利用抑制剂增加包括放射治疗在内的癌症治疗方案的有效性的治疗方法。 在优选的实施方案中，本发明的化合物，组合物和治疗方法用于治疗患有白血病的患者（例如急性骨髓性白血病（AML）和相关的癌症）。在这些治疗的某些方面，化合物，组合物和治疗方法 本发明作为单一疗法（在某些情况下，对已显示出对Topo IIalpha抑制剂如VP-16具有抗性的患者）施用，或者与本文另有描述的Topo IIal抑制剂或其它抗癌剂共同施用，或 结合放射治疗。

    Abstract: A method of treatment and/or prevention of cancer comprises administering agents which cause increased intracellular granularity in cancer cells, at least in an amount sufficient to inhibit proliferation of such cells and preferably in an amount sufficient to lead to cancer cell death. The method is particularly directed to refractory cancer, particularly hormone refractory prostate cancer. The agents identified cause increased intracellular granularity in the cancer cells, and also convert adherent cancer cells to non-adherent cancer cells, leading to cancer cell death. Using the present invention, cancer cells undergo increased intracellular granularity at relatively low agent concentrations, while also inhibiting cell proliferation. Increased concentrations lead to conversion of adherent cancer cells to non-adherent cancer cells, then to cell death. While the exact mechanism of cancer cell degradation and death is not completely understood, the treated cancer cells, including refractory prostate cancer cells, give indications of cell death through an autophagic mechanism. Pharmaceutical compositions related to the presently disclosed methods are also disclosed.
