In certain embodiments APP-specific BACE inhibitors (ASBIs) are provided as well as uses thereof. In certain embodiments methods of preventing or delaying the onset of a pre-Alzheimer's condition and/or cognitive dysfunction, and/or ameliorating one or more symptoms of a pre-Alzheimer's condition and/or cognitive dysfunction, or preventing or delaying the progression of a pre-Alzheimer's condition or cognitive dysfunction to Alzheimer's disease are provided where the method involves administering to a subject in need thereof an APP specific BACE inhibitor (ASBI) in an amount sufficient to prevent or delay the onset of a pre-Alzheimer's cognitive dysfunction, and/or to ameliorate one or more symptoms of a pre-Alzheimer's cognitive dysfunction, and/or to prevent or delay the progression of a pre-Alzheimer's cognitive dysfunction to Alzheimer's disease. In certain embodiments the ASBI is a flavonoid (e.g. galangin) or flavonoid prodrug (e.g., galangin prodrug).

APP specific bace inhibitors (ASBIs) and uses thereof

In various embodiments, compositions and methods are provided for treatment and/or prevention of amyloidogenic diseases. In certain embodiments, the methods entail administering an effective amount of a tropinol ester to a subject in need thereof for prophylactic or therapeutic effect. The methods are particularly useful for prophylactic and therapeutic treatment of Alzheimer's disease. In certain embodiments, methods of reducing the risk, lessening the severity, or delaying the progression or onset of a disease characterized by beta-amyloid deposits in the brain of a mammal are also provided. In certain embodiments, methods of directly or indirectly inhibiting the C-terminal cleavage of APP resulting in the formation of APP-C31 peptide and APPneo (AP-P664) in a mammal are provided.

Tropinol esters and related compounds to promote normal processing of APP

In certain embodiments hydantoin compounds are provided herein that are effective to inhibit BACE activity against APP. Without being bound to a particular theory, it is believed the activity of the hydantoins identified herein appears to be associated with binding to BACE and/or to APP particularly when these moieties form a BACE/APP complex. Accordingly, it is believed the compounds described herein represent a new class of compounds designated herein as APP-Binding-BACE Inhibitors (ABBIs) and provide a new mechanism to modulate APP processing. The hydantoins described herein appear to show improved brain permeability and functional BACE inhibition.

Hydantoins that modulate BACE-mediated app processing

In certain embodiments compounds corresponding in structure to the formula: are provided that are effective to lower p-tau and/or to prevent or reduce elevation of p-tau, particularly in response to stress (e.g., elevated cortisol levels). The compounds are useful in the treatment or prophylaxis of pathologies characterized by abnormal amyloid plaque and or tangle formation and/or deposition.

Substituted [1,2,3]triazolo[4,5-d]pyrimidines that lower stress-induced p-tau

In certain embodiments APP-specific BACE inhibitors (ASBIs) are provided as well as uses thereof. In certain embodiments methods of preventing delaying the onset of a pre-Alzheimer's condition and/or cognitive dysfunction, and/or ameliorating one or more symptoms of a pre-Alzheimer's condition and/or cognitive dysfunction, or preventing or delaying the progression of a pre-Alzheimer's condition or cognitive dysfunction to Alzheimer's disease are provided where the method involves administering to a subject in need thereof an APP specific BACE inhibitor (ASBI) in an amount sufficient to prevent or delay the onset of a pre-Alzheimer's cognitive dysfunction, and/or to ameliorate one or more symptoms of a pre-Alzheimer's cognitive dysfunction, and/or to prevent or delay the progression of a pre-Alzheimer's cognitive dysfunction to Alzheimer's disease. In certain embodiments the ASBI is a flavonoid (e.g. galangin) or flavonoid progrug (e.g., galangin prodrug).

Hydantoins that modulate BACE-mediated APP processing

Various [1,2,3]triazolo[4,5-d]pyrimidines are provided that are effective to lower p-tau and/or to prevent or reduce elevation of p-tau, particularly in response to stress (e.g., elevated cortisol levels). The compounds are useful in the treatment or prophylaxis of pathologies characterized by abnormal amyloid plaque and or tangle formation and/or deposition.

The invention provides compositions and methods for the treatment of mild cognitive impairment (MCI), and for inhibiting, reducing, delaying and/or preventing the progression of MCI to Alzheimer's disease. The methods entail administering an effective amount of one or more compounds selected from the group consisting of tropisetron, disulfuram, honokiol and nimetazepam. The methods also are useful for prophylactic and therapeutic treatment of amyloidogenic diseases, including Alzheimer's disease.

The invention generally relates to the prevention and/or treatment of cancer, and, more specifically, to the treatment of tumors, including solid tumors and their metastases, without radiation or standard chemotherapeutic agents. In one embodiment, the invention involves a method comprising: a) providing a subject with tumor cells, b) removing at least a portion of said tumor cells from said subject to create removed cells, c) treating at least a portion of said removed cells ex vivo, using stimulating agents, including thapsigargin and/or thapsigargin-related compounds, so as to create treated tumor cells; and d) introducing said treated tumor cells (or fragments thereof) in vivo into the same subject to generate anticancer therapeutic effects.

Reagents and methods for cancer treatment and prevention

This invention provides a novel screening system for identifying p53 mimetics/agonists. Also provided are small organic molecules that act as effective p53 mimetics/agonists.

Small molecules that replace or agonize p53 function

In certain embodiments compositions are provided that comprise a pentapeptide comprising the formula: C-X-X-X-Cwhere Cand Care independently selected cysteines or cysteine analogues, or other amino acids with sidechains suitable for cyclization, where the cysteines or cysteine analogs are attached to each other by a linkage that does not comprise X, X, and X; where X, X, and Xare independently selected amino acids; and the peptide, when administered to a cell alters APP signaling and/or switches APP processing from aberrant to normal. The compositions mitigate amyloid plaque formation.
