Summary
Sirtuins are protein deacetylases crucial for gene transcription, metabolism, and aging. This review explores their unique chemistry and the development of mechanism-based sirtuin inhibitors and activators for therapeutic potential.
Area of Science:
- Biochemistry
- Molecular Biology
- Enzymology
Background:
- Sirtuins (Silent Information Regulator 2 enzymes) are conserved protein deacetylases.
- Mammals possess seven sirtuins (SIRT1-7) involved in vital biological processes.
- Sirtuin activity is linked to gene transcription, metabolism, aging, and diseases like cancer.
Purpose of the Study:
- To review the mechanism-based development of sirtuin modulators (inhibitors and activators).
- To provide an updated mechanistic understanding of sirtuin-catalyzed deacetylation.
- To highlight how mechanistic insights inform the design of effective sirtuin modulators.
Main Methods:
- Review of existing literature on sirtuin mechanisms and modulator development.
- Analysis of the unique deacetylation chemistry of sirtuins.
- Exploration of structure-activity relationships in sirtuin modulator design.
Main Results:
- Sirtuin deacetylation is coupled to nicotinamide cleavage from NAD+.
- Three products are generated: deacetylated protein, nicotinamide, and 2'-O-acetyl-ADP-ribose.
- Mechanistic knowledge has successfully guided the design of sirtuin inhibitors and activators.
Conclusions:
- Sirtuins play critical roles in cellular processes and disease.
- Understanding sirtuin deacetylation chemistry is key to developing therapeutic agents.
- Mechanism-based design offers a promising strategy for creating effective sirtuin modulators.

01:24Phase II Reactions: Acetylation Reactions
Acetylation, a phase II biotransformation reaction, introduces an acetyl group to drugs or their metabolites. Acetyltransferase enzymes facilitate this reaction, which resembles α-amino acid conjugation due to the addition of a functional group to the drug molecule.
The substrates for acetylation are typically drugs or their metabolites with an amino, sulfonamide, or hydrazine functional group. Acetylation can occur at several points in the drug molecule, including primary, secondary, and...

02:04Covalently Linked Protein Regulators
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.

01:13Introduction to Mechanisms of Enzyme Catalysis
For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes a mild...

01:08Allosteric Regulation
Allosteric regulation of enzymes occurs when the binding of an effector molecule to a site that is different from the active site causes a change in the enzymatic activity. This alternate site is called an allosteric site, and an enzyme can contain more than one of these sites. Allosteric regulation can either be positive or negative, resulting in an increase or decrease in enzyme activity. Most enzymes that display allosteric regulation are metabolic enzymes involved in the degradation or...
