    摘要: Preparations comprising a single enantiomer or defined ratio of enantiomers of alphadifluoromethylornithine (DFMO) are provided for treating, preventing, controlling the growth of and/or reducing the risk of developing estrogen independent breast cancer or tumor. The preparations containing a single DFMO enantiomer or defined nonracemic ratio of DFMO enantiomers will provide an enhanced pharmacological activity relative to a preparation comprising racemic DFMO. Methods for treating a patient having estrogen independent breast cancer, which methods comprise administering DFMO alone or in combination with taxol, are also provided.

    摘要: Preparations comprising a capsule, tablet or other dosage form containing a core of different types of DFMO are provided. These preparations are capable of providing for the direct and constant delivery of DFMO to the entire GI tract or just the colon and rectum. The DFMO-containing granules include granules specially formulated to achieve rapid DFMO release, and granules formulated to achieve slower DFMO release and/or granules formulated for gastric, enteric or colorectal release. Methods of using the preparations to flood the GI tract with relatively constant levels of DFMO may thus be provided. The ratio of the (+) to the (-)-enantiomeric forms of DFMO in the granules will be controlled so as to enhance the pharmacological profile and reduce toxicity of the preparation relative to racemic DFMO. Preparations and methods for achieving systemic delivery as well as direct colon delivery of DFMO are also described.

    摘要: The present invention provides for the preparation β-adenine nucleosides by coupling an adenine derivative containing an unprotected exocyclic amino group at the C-6 position and a blocked arabinofuranosyl derivative, in the presence of a base and solvent. The present invention also provides for the stereoselective preparation of 2-deoxy-β-D-adenine nucleosides wherein a blocked 2-deoxy-β-D-arabinofuranosyl halide is coupled with the salt of an adenine derivative. The forgoing aspects of the present invention are utilized in the preparation of a clofarabine composition wherein the ratio of β to α-anomer is at least 99:1.

    摘要: The present invention concerns a method for preventing and/or treating cancer in a patient comprising administering an effective amount of substantially purified D enantiomer of difluoromethylornithine (D-DFMO) or an analog of D-DFMO to the patient. D-DFMO or an analog thereof is administered at a dose of about 0.05 to about 20.0 gm/M2/day. D-DFMO or an analog thereof may be administered more than once for the treatment and/or prevention of cancer. Methods of administration as well as compositions and formulations of substantially purified D-DFMO and analogs of D-DFMO are described.

    摘要: The present invention describes the design, synthesis and therapeutic use of a variety of novel inhibitors of polyamine transport. The main feature of this class of transport inhibitors is to incorporate a linker or side chain that prevents the uptake of polyamines and helps to conjugate polyamine analogs to form dimers with high inhibitory potency against polyamine uptake. These new compounds incorporate features that are designed to maximize their chemical and metabolic stability and their ability to bind to the polyamine transporter, and to minimize their toxicity by preventing their absorption by the cells. The purpose of such inhibitors is to prevent the uptake or salvaging of circulating polyamines by rapidly proliferating cells such as tumor cells, in order to potentiate the effect of therapeutic inhibitors of polyamine biosynthesis such as alpha-difluoromethylornithene.
