A selective small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT). Studied for sirtuin and methionine-cycle pharmacology.
5-Amino-1-methylquinolinium (5-Amino-1MQ) is a small-molecule selective inhibitor of nicotinamide N-methyltransferase (NNMT), the enzyme that consumes SAM and nicotinamide to produce 1-methylnicotinamide. NNMT inhibition raises cellular nicotinamide and SAM, indirectly modulating sirtuin substrate availability and methylation potential.
Lumera supplies 5-Amino-1MQ as a lyophilized powder for in-vitro biochemistry use. Vials are sealed under nitrogen and shipped cold-chain at −20 °C from our Kelowna facility.
NNMT enzymatic inhibition assays, cellular SAM/methylation balance studies, sirtuin substrate-availability investigations, and adipocyte energy-expenditure models.

Allow vial to reach room temperature before opening (≥ 20 minutes). Reconstitute with 1.0–2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct stream onto the lyophilized cake.
Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.
Reconstituted solution is stable for 28 days at 2–8 °C in original vial. For longer storage, aliquot into low-binding tubes and hold at −80 °C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.
