  • Patent number: 9744189
    Abstract: Lithium is regarded as the gold standard comparator and benchmark treatment for mania. One of the problems associated with Lithium is its narrow therapeutic window. Recent attempts to find new drugs with similar therapeutic activities have yielded new chemical entities. However, these potential new drugs have yet to match the many bioactivities attributable to lithium's efficacy for the treatment of neuropsychiatric diseases. Consequently, an intense effort for re-engineering lithium therapeutics using cocrystallization is currently underway. The evaluation of pharmacokinetics of previously unexplored lithium salts with organic anions (lithium salicylate and lithium lactate) has found that these lithium salts exhibit profoundly different pharmacokinetics compared to the more common FDA approved salt, lithium carbonate, in rats.
    Type: Grant

The evaluation of pharmacokinetics of previously unexplored lithium salts with organic anions (i.e. lithium salicylate) has found that these lithium salts exhibit profoundly different pharmacokinetics compared to the more common FDA approved salt, lithium carbonate, in rats. Remarkably, lithium salicylate produced elevated blood and brain levels of lithium beyond 48 hours post-dose without the sharp peak that contributes to the toxicity problems of current lithium therapeutics.

  • Patent number: 8574640
    Abstract: A method and composition for stimulating the proliferation and differentiation of stem cells is used to self-repair injury in mammals. A supplement is administered having an effective dose of blueberry, carnosine, catechin, green tea extract, VitaBlue, Vitamin D3 or combinations of these. For example, a therapeutic amount of two or more of the supplements may be selected having a synergistic effect, allowing a lower dose to achieve the same or greater effective protection as a higher dose of any one of the supplements.

  • Publication number: 20100040558
    Abstract: The subject invention concerns materials and methods for treating or preventing a neurodegenerative condition or disease associated with ?-amyloid peptide deposition in neural tissue in a person or animal by administering a therapeutically effective amount of a polyphenol, or an analog, isomer, metabolite, or prodrug thereof, that increases expression or activity of a protein that exhibits ?-secretase activity. The subject invention also provides methods to increase ?-secretase expression and/or activity in cells by administering polyphenol flavonoids like (?)-epigallocatechin-3-gallate (EGCG) and epicatechin (EC), two polyphenols derived from green tea and other plants and that can be produced synthetically. Furthermore, there are provided methods to decrease or inhibit the production of A?1-40 or A?1-42 by administering the EGCG and EC compounds, their analogs, metabolites, and prodrugs.
