Synthesis and Assay of SIRT1-Activating Compounds

The NAD+-dependent deacetylase SIRT1 plays key roles in numerous cellular processes including DNA repair, gene transcription, cell differentiation, and metabolism. Overexpression of SIRT1 protects against a number of age-related diseases including diabetes, cancer, and Alzheimer's disease. Moreover, overexpression of SIRT1 in the murine brain extends lifespan. A number of small-molecule sirtuin-activating compounds (STACs) that increase SIRT1 activity in vitro and in cells have been developed. While the mechanism for how these compounds act on SIRT1 was once controversial, it is becoming increasingly clear that they directly interact with SIRT1 and enhance its activity through an allosteric mechanism. Here, we present detailed chemical syntheses for four STACs, each from a distinct structural class. Also, we provide a general protocol for purifying active SIRT1 enzyme and outline two complementary enzymatic assays for characterizing the effects of STACs and similar compounds on SIRT1 activity.

A series of imidazo[1,2-b]thiazole derivatives is shown to activate the NAD+-dependent deacetylase SIRT1, a potential new therapeutic target to treat various metabolic disorders. This series of compounds was derived from a high throughput scree
SIRTUIN POLYMORPHISMS AND METHODS OF USE THEREOF
-
Page/Page column 35, (2008/12/08)
Provided herein are methods for diagnosis and prognosis using polymorphic variants of sirtuins. Such polymorphic may be used, for example, to identify subjects that would be responsive to treatment with a sirtuin modulating compound andor subjects that are suffering from or susceptible to a disease mediated by a sirtuin. Also provided are methods for determining the predictive value of a sirtuin polymorphic variant, methods for evaluating sirtuin modulating compounds, and methods for determining appropriate dosage andor treatment regimens for subjects having one or more sirtuin polymorphic variants. Screening methods for identifying sirtuin modulating compounds using polymorphic variants of a sirtuin are also provided.
