Abstract: In accordance with various aspects of the invention, CXCR4 agonists, including SDF-1 polypeptides and SDF-1 polypeptide homologues, may be used in reducing the rate of hematopoietic cell multiplication. Methods of the invention may comprise administration of an effective amount of an CXCR4 agonist to cells selected from the group consisting of hematopoietic stem cells and hematopoietic progenitor cells. Cells may be treated in vitro or in vivo in a patient. A therapeutically effective amount of the CXCR4 agonist may be administered to a patient in need of such treatment. Patients in need of such treatments may include, for example patients requiring bone marrow or peripheral blood stem cell transplantation.

Abstract: The present invention is concerned with chemokine analogs, including IL-8 analogs, IP-10 analogs, MIP-1? analogs, RANTES analogs, I-309 analogs, MCP-1 analogs, and CCL28 analogs, that are useful for the treatment of a variety of diseases and disorders, and as an adjunct to the treatment of a variety of diseases and disorders. A therapeutically effective amount of the chemokine analog may be administered to a patient in need of such treatment.

Abstract: In accordance with various aspects of the invention, CXCR4 antagonists may be used to treat hematopoietic cells, such as progenitor or stem cells, to promote the rate of cellular multiplication, self-renewal, proliferation or expansion. CXCR4 antagonists may be used therapeutically to stimulate hematopoietic stem/progenitor cell multiplication/self-renewal.

Abstract: In various aspects, the invention provides compounds that bind to one or more RANTES receptors for the treatment of chemokine mediated disease states, such as compounds of formula (I):

Abstract: The invention provides therapeutic and biological uses of chemokine-receptor-binding compounds including uses in the treatment of disease states mediated by chemokines. The relevant chemokines may for example be monocyte chemoattractant protein-one (MCP-1) or interleukin-8 (IL-8), and the relevant chemokine receptors may for example be corresponding chemokine receptors (CCR-2, CCR-4, CXCR-1, and CXCR-2). In one aspect, the invention provides for the use of phenanthrene-9,10-dione in the treatment of multiple sclerosis.

Abstract: The invention provides therapeutic and biological uses of chemokine-receptor-binding compounds (including chemokine receptor ligands such as chemokine receptor agonists or antagonists), such as naphthoic acid derivatives, including uses in the treatment of disease states mediated by chemokines. The relevant chemokine may for example be stromal cell-derived factor (SDF)-1, and the relevant chemokine receptors may for example be corresponding chemokine receptor (CXCR-4). In other aspects, the invention provides corresponding pharamaceutical compositions and therapeutic methods. In one aspect, for example, the invention provides for the use of 3-Hydroxy-2-naphthoic acid in the treatment of disease.

Abstract: The invention provides therapeutic and biological uses of chemokine-receptor-binding compounds (including chemokine receptor ligands such as chemokine receptor agonists or antagonists), such as benzopyrone derivatives, including uses in the treatment of disease states mediated by chemokines. The relevant chemokine may for example be interleukin-8 (IL-8), and the relevant chemokine receptors may for example be corresponding chemokine receptors (CXCR-1 and/or CXCR-2). In other aspects, the invention provides corresponding pharamaceutical compositions and therapeutic methods. In one aspect, for example, the invention provides for the use of [7-[benzopyrone-5′(3′-amino)-thiazole]-phenylalanine-benyl ester in the treatment of disease.
