Nicotinamide riboside increases NAD[+] levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism and protection against high fat diet-induced metabolic abnormalities.

RK-9123016 is a SIRT2 inhibitor. RK-9123016 increases the acetylation level of eukaryotic translation initiation factor 5A (eIF5A), a physiological substrate of SIRT2, and reduces cell viability of human breast cancer cells accompanied with a decrease in c-Myc expression.

Tenovin-1 (Tenovin1) is a small molecules that activate p53 and decreases tumor growth through inhibition of the protein-deacetylating activities of SirT1 and SirT2.
