Abstract:
Compounds disclosed which inhibit ABCB1 transporter protein are useful for treating diseases in which ABCB1 transporter protein mediates the disease state, including numerous cancers, including hematopoietic cancers, including various leukemias, especially T-lineage acute lymphoblastic leukemia, as well as cancerous tumors, especially forms which exhibit multiple drug resistance. Pharmaceutical compositions which comprise an inhibitor of ABCB1 transporter protein and at least one additional anticancer agent, optionally in combination with a pharmaceutically acceptable carrier, additive or excipient are another aspect of the present invention. A flow cytometry based, high-throughput screening (HST) assay that quantifies ABCB1 efflux is also disclosed. Methods of identifying inhibitors of ABCB1, ABCG2 and ABCC1 transporter proteins are also disclosed.
Abstract:
The current invention is in the field of molecular biology/pharmacology and provides compounds which modulate the effects of GPR30 as well as the classical estrogen receptors alpha and beta (ERα and ERβ). These compounds may function as agonists and/or antagonists of one or more of the disclosed estrogen receptors. Diseases which are mediated through one or more of these receptors include cancer (particularly breast, reproductive and other hormone-dependent cancers, leukemia, colon cancer, prostate cancer), reproductive (genito-urological) including endometreitis, prostatitis, polycystic ovarian syndrome, bladder control, hormone-related disorders, hearing disorders, cardiovascular conditions including hot flashes and profuse sweating, hypertension, stroke, obesity, osteoporosis, hematologic diseases, vascular diseases or conditions such as venous thrombosis, atherosclerosis, among numerous others and disorders of the central and peripheral nervous system, including depression, insomnia, anxiety, multiple sclerosis, neuropathy, neurodegenerative disoders such as Parkinson's disease and Alzheimer's disease, as well as inflammatory bowel disease, Crohn's disease, coeliac (celiac) disease and related disorders of the intestine. A contraceptive indication to prevent or reduce the likelihood of pregnancy after intercourse is a further aspect of the present invention.
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:
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.
