# Glossary: NNMT Inhibitors

### What are NNMT Inhibitors?

Nicotinamide N‑methyltransferase (NNMT) is an enzyme that methylates nicotinamide, influencing NAD+ salvage pathways and cellular metabolism. NNMT inhibitors are compounds that block this enzyme’s activity, allowing researchers to study how altered methylation impacts energy balance, metabolic rate and cellular signalling.

### Research Applications

- Investigating the regulation of NAD+ synthesis and nicotinamide metabolism.
- Modelling metabolic disorders, obesity and insulin resistance.
- Exploring mechanisms of ageing, sirtuin activity and mitochondrial function.

### Research Use Only
