The invention relates to relatively short peptides (termed &#x3b1;-conotoxins herein), about 10-25 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds. The &#x3b1;-conotoxins, as described herein, are useful for as neuromuscular blocking agents, such as muscle relaxants.

&#x3b1;-conotoxin peptides

The invention relates to relatively short peptides (termed O-Superfamily conotoxins herein), about 20-40 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds.

O-superfamily conotoxin peptides

The present invention is directed to contulakin-G (which is the native glycosylated peptide), a des-glycosylated contulakin-G (termed Thr -contulakin-G), and derivatives thereof, to a cDNA clone encoding a precursor of this mature peptide and to a precursor peptide. The invention is further directed to the use of this peptide as a therapeutic for anti-seizure, anti-inflammatory, anti-shock, anti-thrombus, hypotensive, analgesia, anti-psychotic, Parkinson's disease, gastrointestinal disorders, depressive states, cognitive dysfunction, anxiety, tardive dyskinesia, drug dependency, panic attack, mania, irritable bowel syndrome, diarrhea, ulcer, GI tumors, Tourette's syndrome, Huntington's chorea, vascular leakage, anti-arteriosclerosis, vascular and vasodilation disorders, as well as neurological, neuropharmalogical and neuropsychopharmacological disorders.

Contulakin-G, analogs thereof and uses therefor

The present invention is directed to conantokin peptides, conantokin peptide derivatives and conantokin peptide chimeras, referred to collectively as conantokins, having 10-30 amino acids, including preferably two or more &ggr;-carboxyglutamic acid residues. The conantokins are useful for the treatment of neurologic and psychiatric disorders, such as anticonvulsant agents, neuroprotective agents or analgesic agents.

Conantokins

Contulakin-G, analogs thereof and uses thereof

The present invention is directed to the use of conantokin peptides, conantokin peptide derivatives and conantokin peptide chimeras, referred to collectively as conantokins, having 10-30 amino acids, including preferably two or more &ggr;-carboxyglutamic acid residues, for the treatment of neurologic and psychiatric disorders, such as anticonvulsant agents, neuroprotective agents or analgesic agents. Neurologic disorders and psychiatric disorders include, epilepsy, convulsions, neurotoxic injury (associated with conditions of hypoxia, anoxia or ischemia which typically follows stroke, cerebrovascular accident, brain or spinal cord trauma, myocardial infarct, physical trauma, drowning, suffocation, perinatal asphyxia, or hypoglycemic events), neurodegeneration (associated with Alzheimer's disease, senile dementia, Amyotrophic Lateral Sclerosis, Multiple Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease, schizophrenia, AIDS dementia, multi-infarct dementia, Binswanger dementia and neuronal damage associated with uncontrolled seizures), chemical toxicity (such as addiction, morphine tolerance, opiate tolerance, opioid tolerance and barbiturate tolerance), pain (acute, chronic, migraine), anxiety, major depression, manic-depressive illness, obsessive-complusive disorder, schizophrenia and mood disorders (such as bipolar disorder, unipolar depression, dysthymia and seasonal effective disorder) and dystonia (movement disorder), sleep disorder, muscle relaxation and urinary incontinence. In addition, the conantokins are useful for treating HIV infection, ophthalmic indications and memory, learning or cognitive deficits.

Use of conantokins

The present invention is directed to the use of conantokin peptides, conantokin peptide derivatives and conantokin peptide chimeras, referred to collectively as conantokins, having 10-30 amino acids, including preferably two or more &ggr;-carboxyglutamic acid residues, for the treatment of neurologic and psychiatric disorders, such as pain, e.g., as an analgesic agent.

Use of conantokins for treating pain

The invention relates to relatively short peptides (termed &agr;-conotoxins herein), about 10-25 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds. The &agr;-conotoxins, as described herein, are useful for as neuromuscular blocking agents, such as muscle relaxants.

&agr;-conotoxin peptides

The present invention is directed to the use of conantokin peptides, conantokin peptide derivatives and conantokin peptide chimeras, referred to collectively as conantokins, having 10-30 amino acids, including preferably two or more &ggr;-carboxyglutamic acid residues, for the treatment of neurologic and psychiatric disorders, such as anticonvulsant agents, neuroprotective agents or analgesic agents. Neurologic disorders and psychiatric disorders include epilepsy, convulsions, neurotoxic injury (associated with conditions of hypoxia, anoxia or ischemia which typically follows stroke, cerebrovascular accident, brain or spinal cord trauma, myocardial infarct, physical trauma, drowning, suffocation, perinatal asphyxia, or hypoglycemic events), neurodegeneration (associated with Alzheimer's disease, senile dementia, Amyotrophic Lateral Sclerosis, Multiple Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease, schizophrenia, AIDS dementia, multi-infarct dementia, Binswanger dementia and neuronal damage associated with uncontrolled seizures), chemical toxicity (such as addiction, morphine tolerance, opiate tolerance, opioid tolerance and barbiturate tolerance), pain (acute, chronic, migraine), anxiety, major depression, manic-depressive illness, obsessive-compulsive disorder, schizophrenia and mood disorders (such as bipolar disorder, unipolar depression, dysthymia and seasonal effective disorder) and dystonia (movement disorder), sleep disorder, muscle relaxation and urinary incontinence. In addition, the conantokins are useful for treating HIV infection, ophthalmic indications and memory, learning or cognitive deficits.
