Definitions
- the invention relates to the use of zinc chelating compounds in the treatment of neurotoxic injury.
- the present invention comprises a method of treating neurotoxic injury in a patient suffering said injury, comprising administering to said patient a zinc chelating compound in an amount sufficient to treat said neurotoxic injury.
- composition comprising the zinc chelating compound
- administration of the composition comprising the zinc chelating compound is carried out by injection or infusion of the composition into the patients cerebrospinal fluid.
- Chelatable Zn ⁇ + is present in large quantities in presynaptic vesicles of central excitatory neurons (Danscher et al., 1985; Frederickson et al., 1983), and released with synaptic activity or membrane depolarization (Assaf and Chung, 1984; Howell et al., 1984; Charton et al., 1985). Although the precise role of released synaptic zinc is not known, it blocks NMDA receptor- mediated current (Westbrook and Mayer, 1987; Peters et al., 1987; Christine and Choi, 1990) and GABA receptor-mediated current (Westbrook and
- Treating neurotoxic injury within the meaning of the present invention means reducing the extent of damage to central neurons surrounding a central neuron which has released Zn + due to its having been damaged by a neurotoxic event.
- Neurotoxic events include acute neurological insults such as hypoxia/ischemia, such as occurs during stroke, cardiac arrest, hypoglycemia, epilepsy or trauma.
- Neurotoxic events may also be chronic neuronal damage caused by neurodegenerative disorders such as Huntington's disease, Alzheimer's disease, amyotropic lateral sclerosis, and the neurodegenerative effects of AIDS.
- the present invention also comprises a method of treating diseases, such as those described above, in which said neurotoxic injury occurs.
- the zinc chelating compounds useful in accordance with the invention are not critical. Any conventional compound which is capable of chelating Zn 2+ and which is pharmaceutically acceptable for injection into cerebral spinal fluid may be used in accordance with the invention.
- EDTA ethylenediaminetetraacetic acid
- the preferred zinc chelating compound for use in accordance with the invention is disodium- calcium EDTA ("CaEDTA”), especially the form of CaEDTA known as edetate calcium disodium injection, USP (e.g., Calcium Disodium Versenate, 3M Pharmaceuticals, St. Paul, Minnesota).
- CaEDTA disodium- calcium EDTA
- USP e.g., Calcium Disodium Versenate, 3M Pharmaceuticals, St. Paul, Minnesota
- Another preferred zinc chelating compound useful in accordance with the invention is 3-mercapto-D-valine (penicillamine), which is a chelating agent usually applied to the treatment of Wilson's disease where it removes excess copper.
- TPEN N,N,N',N'-tetrakis(2-pyridylmethyl)-ethylenediamine
- the zinc chelating compound used in accordance with the present invention may be administered to the cerebrospinal fluid by any conventional means.
- the preferred method of administration is by injection or chronic pump infusion into the lateral ventricles of the patient's brain or into the lumbar sac of the patient.
- the zinc chelating compound is preferably administered as a composition containing the zinc chelating compound and a pharmaceutically acceptable carrier compatible with the compound.
- any conventional pharmaceutically acceptable carrier may be utilized.
- Typical carriers for administration by injection would be sterile aqueous/buffered solutions, preferably water for injecion or unbuffered or buffered physiological saline.
- the zinc chelating compound is preferably present in the carrier at a concentration of 1 mM - 300 mM, especially from 50 mM - 200 mM.
- the zinc chelating compound is administered to adults daily in an amount from about 0.1 mg/kg to about 100 mg/kg daily, in single or divided doses, or continuously through chronic pump infusion.
- the preferred dosage will vary depending upon the indication for which the method of the invention is being used to treat.
- the administration of a dosage from about 5 mg/kg to about 50 mg/kg daily, carried out for from 1 to 7 days, is preferred.
- Administration may be carried out by injection or by infusion utilizing a chronic infusion pump.
- a dosage of from aboutl mg/kg to about 10 mg/kg daily is preferred, carried out for months to years, preferably utilizing a chronic infusion pump.
- the present invention also comprises a method of treating neurotoxic injury in a patient suffering said injury by administering to said patient a composition comprising a zinc chelating compound and carrier, wherein both the compound and the carrier are pharmaceutically acceptable for injection.
- the prefered zinc chelating compounds are CaEDTA and 3- mercapto-D-valine, with CaEDTA being especially preferred.
- the zinc chelating compound is preferably administered in an amount from about 01. mg/kg to about 100 mg/kg daily, especially in an amount from about 5 mg/kg to about 50 mg/kg daily for the treatment of acute neurotoxic conditions and in an amount from about 1 mg/kg to about 10 mg/kg daily for chronic neurotoxic conditions.
- the preferred method of administration is the injection or infusion of the pharmaceutical composition comprising the zinc chelating compound and the carrier into the cerebrospinal fluid (e.g., the lateral ventricles or lumbar sac) of the patient.
- the preferred duration of treatment is from 1 to 7 days for acute neurotoxic cond tions, and for months to years for chronic neurotoxic conditions.
- the present invention preferably comprises a method of treating stroke in a patient suffering said stroke by administering to said patient a composition comprising a zinc chelating compound and a carrier, wherein both the compound and the carrier are pharmaceutically acceptable for injection.
- the preferred zinc chelating compounds are CaEDTA and 3- mercapto-D-valine, with CaEDTA being especially preferred.
- the zinc chelating compound is preferably administered in an amount from about 0.1 mg/kg to about 100 mg/kg daily, especially in an amount from about 5 mg/kg to about 50 mg/kg daily for the treatment of stroke.
- the preferred method of administration is the injection or infusion, especially injection, of the pharmaceutical composition comprising the zinc chelating compound and the carrier into the cerebrospinal fluid (e.g., the lateral ventricles or lumbar sac) ofthe patient.
- the preferred duration of treatment is from 1 to 7 days.
- CaEDTA selectively blocks Zn ⁇ +- induced neuronal degeneration, but not the Ca2+-overload neurotoxicity induced by glutamate agonists.
- CaEDTA disodium-calcium-EDTA
- Hippocampal sections from the treated and untreated rats were stained with the zinc-sensitive dye, TSQ (Frederickson et al., 1987). The examination of these sections showed that in the untreated rats zinc translocated from presynaptic inputs to degenerating hilar neuronal cell bodies between 3-24 hours after the ischemia. In the treated rats, CaEDTA blocked not only this zinc translocation, but also prevented subsequent hilar neuronal degeneration as assessed 3 days later.
- TSQ staining also revealed the delayed appearance of zinc in CA1 pyramidal neuronal cell bodies of untreated rats 24-72 hours post ischemia.
- the CaEDTA treatment prior to the induced ischemia attenuated both the appearance of zinc in CA1 pyramidal neurons, and CA1 neuronal degeneration.
