  • Patent number: 9150558
    Abstract: The invention relates to the design and synthesis of novel anabaseine-based compounds, which are useful in treating or preventing a wide variety of conditions, including nervous system diseases or disorders, such as, schizophrenia, Alzheimer's disease, Parkinson's disease, drug dependence, and substance addiction, and compositions, kits, and methods thereof. The invention also provides novel anabaseine-based compounds, compositions, kits, and methods thereof for treating or preventing non-nerve system diseases or disorders (such as, inflammation and cancer) in a subject identified in need thereof. Certain enantiomeric compounds of the invention exhibited enhanced selectivity toward ?7 nAChRs relative to alpha4beta2 nAChRs. Other enantiomeric compounds of the invention exhibited enhanced selectivity for alpha4beta2 nAChRs relative to ?7 nAChRs.

  • Patent number: 6077680
    Abstract: Disclosed are methods and compositions comprising DNA segments, and proteins derived from sea anemone species. More particularly, it concerns the novel ShK toxin, ShK toxin analogs, chemically-modified toxin analogs, and nucleic acid segments encoding the ShK toxin from Stichodactyla helianthus. Various methods for making and using these DNA segments, DNA segments encoding synthetically-modified ShK toxins, and native and synthetic ShK peptides are disclosed, such as, for example, the use of DNA segments as diagnostic probes and templates for protein production, and the use of proteins, fusion protein carriers and peptides in various immunological and diagnostic applications.

  • Patent number: 5741802
    Abstract: The invention concerns novel anabaseine-related compounds that are useful in treating certain degenerative neural diseases such as Alzheimer's and Parkinson's which apparently involve decreased function of cerebral cortical nicotinic receptors. The compounds showed activity in both in vitro and in active and passive active avoidance studies in animal models. An exemplary active compound is a 3-substituted 2,4-dimethoxy-benzylidene anabaseine.
