Abstract: Tricyclic pyrone compounds having high oral bioavailability, excellent blood-brain barrier permeability, and low toxicity are presented. Administration of the compounds to Alzheimer's Disease transgenic models resulted in substantially reduced soluble and insoluble A? species in the brain without affecting general behavior and motor coordination. Furthermore, in addition to blocking the toxicity and formation of both intraneuronal and extracellular A? aggregates, the compounds also increase cellular cholesterol efflux, restore axonal trafficking, and enhance hippocampal synaptic plasticity.

Abstract: Methods for deterring microglia-mediated neurotoxicity in a human or non-human animal subjects comprising the step of inhibiting or blocking the intermediate-conductance calcium-activated potassium channel KCa3.1 in microglia, such as in subjects how suffer from neurodegenerative diseases (e.g., Alzeheimer's Disease) or ischemic/anoxic/hypoxic conditions. The inhibition or blocking of the KCa1.3 channels may be accomplished by administering a KCa3.1 inhibiting substance, such as 1-[(2-chlorophenyl)diphenylmethyl]-1H-pyrazole (TRAM-34).

Abstract: In one aspect, the present invention provides for compounds and labeled compounds of Formula I, and pharmaceutical compositions thereof.
