Thiazolopyridine sirtuin modulating compounds
Provided herein are novel sirtuin-modulating compounds of Structural Formula (Ia) and methods of use thereof. The sirtuin-modulating compounds may be used for increasing the lifespan of a cell, and treating and/or preventing a wide variety of diseases and disorders including, for example, diseases or disorders related to aging or stress, diabetes, obesity, neurodegenerative diseases, cardiovascular disease, blood clotting disorders, inflammation, cancer, and/or flushing as well as diseases or disorders that would benefit from increased mitochondrial activity. Also provided are compositions comprising a sirtuin-modulating compound in combination with another therapeutic agent.
1. A pharmaceutical composition for topical administration comprising a compound represented by the structural formula:
or a pharmaceutically acceptable salt thereof in a pharmaceutically acceptable topical carrier.
2. The pharmaceutical composition for topical administration of claim 1 , comprising 0.001 to 10% by weight of the compound.
3. The pharmaceutical composition for topical administration of claim 2 , comprising 0.1 to 5% by weight of the compound.
4. The pharmaceutical composition for topical administration of claim 1 , comprising 0.25 to 75% by weight of the compound.
5. The pharmaceutical composition for topical administration of claim 4 , comprising 0.25 to 30% by weight of the compound.
6. The pharmaceutical composition for topical administration of claim 5 , comprising 0.25 to 15% by weight of the compound.
7. The pharmaceutical composition for topical administration of claim 6 , comprising 1.0 to 10% by weight of the compound.
