    Abstract: A purification method is disclosed for a predetermined water-insoluble extractant present in a liquid phase composition that additionally contains one or more additional extractants, synthesis reaction starting materials, and reaction byproducts dissolved as solutes in an organic diluent. An ion-containing compound is admixed with the composition to form an extractant/ion complex in the organic diluent phase that has an affinity for a new phase that is greater than the affinity for the first-named phase. The predetermined extractant/ion complex is separated from the diluent by using the new phase affinity, and the extractant/ion complex is preferably although not necessarily recovered. The extractant/ion complex is separated into extractant and ion. The extractant is recovered. Exemplary extractants include polyethers, crown ethers, crown thioethers, calixarenes, polyamines, cryptands, porphyrins and the like.

  • Patent number: 6949679
    Abstract: 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.

  • Patent number: 6255277
    Abstract: A method for preventing adverse effects associated with the use of a medical device in a patient by introducing into the patient a device of which at least a portion includes a prophylactic or therapeutic amount of a nitric oxide adduct. The nitric oxide adduct can be present in a matrix coating on a surface of the medical device; can be coated per se on a surface of the medical device; can be directly or indirectly bound to reactive sites on a surface of the medical device; or at least a portion of the medical device can be formed of a material, such as a polymer, which includes the nitric oxide adduct. Also disclosed is a method for preventing adverse effects associated with the use of a medical device in a patient by introducing the device during a medical procedure and before or during said procedure locally administering a nitric oxide adduct to the site of contact of said device with any internal tissue.

  • Patent number: 6235794
    Abstract: Polyamines having the formula: or a salt thereof with a pharmaceutically acceptable acid wherein: R1-R5 may be the same or different and are alkyl, aryl, aryl alkyl, cycloalkyl or hydrogen; at least one of R1 and R2 and at least one of R4 and R5 are not hydrogen, and any of the alkyl chains may optionally be interrupted by at least one etheric oxygen atom, excluding N1,N3-diethylspermidine and N1,N3-dipropylspermidine; and A and B are bridging groups which effectively maintain the distance between the nitrogen atoms such that the polyamine: (i) is capable of uptake by a target cell upon administration of the polyamine to a human or non-human animal; and (ii) upon uptake by the target cell, competitively binds via an electrostatic interaction between the positively charged nitrogen atoms to substantially the same biological counter-anions as the intracellular natural polyamines in the target cell.

  • Patent number: 5994585
    Abstract: The present invention relates to an amination process for the manufacture of polyamines. The purpose of the process is to increase the selectivity of linear aminated products and to prevent the formation of discoloring by-products or by-products which may later cause discoloration. According to the process this is achieved by performing, in a first part of the process, the amination to a conversion degree of between 50 and 98% by weight, calculated on the total yield of polyamines, at a proportionally time-weighted average temperature, which is at least 15.degree. C. higher than the proportionally time-weighted average temperature in the remaining part.
