Sirtuins are a class of enzymes with nicotinamide adenine dinucleotide
(NAD)-dependent protein lysine deacylase function. By deacylating various
substrate proteins, including histones, transcription factors, and metabolic
enzymes, sirtuins regulate various biological processes, such as transcription,
cell survival, DNA damage and repair, and longevity. Small molecules that can
inhibit sirtuins have been developed and many of them have shown anticancer
activity. Here, we summarize the major biological findings that connect sirtuins
to cancer and the different types of sirtuin inhibitors developed. Interestingly,
biological data suggest that sirtuins have both tumor-suppressing and
tumor-promoting roles. However, most pharmacological studies with small-molecule
inhibitors suggest that inhibiting sirtuins has anticancer effects. We discuss
possible explanations for this discrepancy and suggest possible future directions
to further establish sirtuin inhibitors as anticancer agents.
