  • Patent number: 10130708
    Abstract: 2:1 cocrystals of amino acids and Li+ salts crystallize from hot water to afford water stable cationic networks based upon tetrahedral lithium cations: bilayered square grids, a lithium zeolitic metal-organic material (LiZMOM) and several lithium diamondoid metal-organic materials (LiDMOMs). The compositions may be used as a pharmaceutical for the treatment of suicidality and other disorders that require lithium to penetrate the blood brain barrier and exert therapeutic effects in the CNS. Advantageously, the novel cocrystal forms described herein may be used to lower the oral dose required to achieve therapeutic concentrations of lithium in the brain, thus reducing the peripheral toxicity and potentially broadening the therapeutic index in comparison to conventional lithium forms.

  • Publication number: 20150157597
    Abstract: The invention relates to treatment of neurodegenerative diseases with JAK/STAT pathway inhibitors to eliminate extracellular cell signaling events leading to cell cycle abrogation and/or apoptosis. Primary neurons were administered neurotoxic proteins, such as gp120, Tat, or gp120 and Tat, with or without IFN-? added, resulting in neuronal death, and simulated neurodegenerative diseases. The neurodegenerative disease is treated using a JAK/STAT pathway inhibitor, including (-)-epigallocatechin-3-gallate (EGCG), to modulate JAK1 or STAT1 phosphorylation, resulting in resistance to gp120 or Tat neurotoxicity. The invention may be used to treat neurons afflicted with HIV-associated Dementia, multiple sclerosis, Alzheimer's Disease, Parkinson's Disease, amyotrophic lateral sclerosis, or Pick's Disease, and may act in conjunction with antiviral treatment, like HAART.

  • Publication number: 20100267733
    Abstract: Treatment of microglial cells with nicotine and THC synergistically attenuate the microglial activation. Using microglial activation, the combination of THC and nicotine interact synergistically reduced LPS induced TNF-? release, showing that the combination of THC and nicotine clinically have greater efficacy in reducing neuroinflammation with less side effects than either drug given alone. CD40 signaling was found critically involved in pathological activation of microglial cells. This invention is also relevant to peripheral inflammation as well thru macrophages. In addition, other cannabinoids and other nicotinic-like medications currently in development are also covered under this discovery.

Primary neurons were administered neurotoxic proteins, such as gp120, Tat, or gp120 and Tat, with or without IFN-? added, resulting in neuronal death, and simulated neurodegenerative diseases. The neurodegenerative disease is treated using a JAK/STAT pathway inhibitor, including (—)-epigallocatechin-3-gallate (EGCG), to modulate JAK1 or STAT1 phosphorylation, resulting in resistance to gp120 or Tat neurotoxicity. The invention may be used to treat neurons afflicted with HIV-associated Dementia, multiple sclerosis, Alzheimer's Disease, Parkinson's Disease, amyotrophic lateral sclerosis, or Pick's Disease, and may act in conjunction with antiviral treatment, like HAART.

  • Patent number: 6979698
    Abstract: The treatment of learning, memory, and age-related memory disorders includes administration of a nicotine antagonist. The preferred nicotine antagonists are mecamylamine, a mecamylamine analog, or a mecamylamine stereoisomer. The effective amount of the nicotine antagonist is 0.005–1.00 mg/kg/day. Alternatively, the method utilizes a partial nicotine agonist.

  • Patent number: 6034079
    Abstract: Nicotine-responsive neuropsychiatric disorders can be treated by administering a nicotine antagonist, particularly mecamylamine. Combination therapy of mecamylamine with a neuroleptic drug also is disclosed. The neuropsychiatric disorders include Tourette's syndrome, schizophrenia, depression, bipolar disorder, tremors, attention deficit hyperactivity disorder, obsessive-compulsive disorder, hemidystonia, rage outbursts and tardive dyskinesia.
