Patent number: 4952607Abstract: The present invention relates to copper complexes exhibiting superoxide dismutase-like activity in mammalian cells. The copper complexes, which act as superoxide radical (O.sub.2.sup.-) scavengers, are used in treating cancer by replacing the lost superoxide dismutase activity which characterizes tumor systems. The low molecular weight and lipid solubility of the copper complexes facilitate penetration of cell membranes. Depending upon the specific type of copper complex used, treatment may result in decreased tumor growth, increased survival of the host organism, decreased tumor metastasis or induced morphological differentiation of cancerous cells. The copper complexes used according to the invention include copper salicylate complexes, their solvates as well as mixtures thereof. A method for the treatment of cancer using these copper complexes is also disclosed.Type: GrantFiled: January 30, 1986Date of Patent: August 28, 1990Assignee: International Copper Research Association, Inc.Inventors: John R. J. Sorenson, Larry W. Oberley

Patent number: 4758555Abstract: Copper-dependent enzymes are required for normal brain development and function. Copper deficiency can result in pathological disorders accompanied by convulsive seizures or tremors in man and animals. The present invention is directed to a method for treating convulsions or epilepsy comprising administration of a therapeutically effective amount of an organic compound of copper having anticonvulsant activity. Those compounds include copper complexes of carboxylic acids, acylsalicylates, salicylates, amino acids, imines and known anticonvulsant and antiepileptic drugs.Type: GrantFiled: December 8, 1986Date of Patent: July 19, 1988Assignee: International Copper Research AssociationInventor: John R. J. Sorenson

Patent number: 4657928Abstract: Methods are described for using organic copper complexes or their solvates, which exhibit superoxide dismutase activity and act as superoxide radical scavengers, as radioprotectants to protect mammalian cells from damage caused by gamma- or x-irradiation. Treatment can result in the protection of normal tissues in cancer patients undergoing radiotherapy and in the protection of individuals who may be at risk with regard to hazardous effects of exposure to occupational or environmental ionizing radiation.Type: GrantFiled: September 25, 1984Date of Patent: April 14, 1987Assignee: International Copper Research Association, Inc.Inventor: John R.

Patent number: 4012221Abstract: A method and composition for destroying disease transmitting trematode hosts over a sustained period of time by treatment with a controlled release toxicant composition. The composition comprises a water-soluble, inorganic copper salt capable of releasing copper ions in water which is substantially uniformly dispersed in a moderately crosslinked elastomer in which the copper salt is insoluble. The composition, when contacted with water, allows for the controlled and sustained release of copper ions to cause chronic intoxication and eventual destruction of the molluscan target.Type: GrantFiled: May 13, 1975Date of Patent: March 15, 1977Assignee: International Copper Research Association Inc.Inventors: Katherine E. Walker, Nathan F. Cardarelli
