Abstract
An agent and method for the prevention and treatment of toxicity caused by heavy metals such as depleted uranium, tungsten and nickel and metals such as iron, lead and copper. The agent is a chelating agent such as picolinic acid or derivatives thereof. The agent chelates and inactivates the metals which can be carcinogenic or poisonous. The agent can be administered to chelate excessive copper as a result of Wilson's disease. The agent can be administered orally or by other systemic routes such as injections and the like.
Claims29
A method of preventing and treating the deleterious effects of exposure to toxic metals, the method comprising the administration of a therapeutically effective amount of an agent to a human or animal to chelate and inactivate the heavy metal, the agent having the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from the group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A method of treating heavy metal toxicity comprising the administration of a therapeutically effective amount of a metal ion chelating agent to animal or human, said agent disposed to chelate a heavy metal ion which is the causative agent of the heavy metal toxicity, said agent represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from the group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A method of preventing and treating cell mutations in a subject wherein the cell mutations are caused by exposure to heavy metal comprising the administration of a therapeutically effective amount of a metal chelating agent to said subject to chelate a heavy metal ion which causes the cell mutation, said metal chelating agent represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from a group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A method of inactivating a mutagenic heavy metal comprising the step of exposing said mutagenic heavy metal to a metal chelating agent so that the metal chelating agent binds to the mutagenic heavy metal so as to inactivate the mutagenic heavy metal, said metal chelating agent represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from the group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A kit for carrying in duty by a soldier for the prevention and treatment of heavy metal toxicity upon exposure to a heavy metal comprising an agent in an oral dosage form for oral administration to the soldier upon exposure, wherein said agent is represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from the group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A method of treating Wilson's disease comprising the administration of a therapeutically effective amount of a metal chelating agent to a patient to chelate excess copper, wherein said metal chelating agent is represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from the group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
A method of preventing or treating lead poisoning comprising the administration of a therapeutically effective amount of a metal chelating agent to a patient to chelate the lead, wherein said metal chelating agent is represented by the following structure:
- or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and R4 are selected from a group consisting of a peptide of sixteen amino acids, carboxyl group, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, secondary butyl group, tertiary butyl group, pentyl group, isopentyl group, neopentyl group, fluorine, chlorine, bromine, iodine and hydrogen.
