Description
Nicotinamide is a precursor of NAD and NADP , which serve essential functions in modulating cellular redox status and controlling signaling and transcriptional events. 1-Methylnicotinamide (MNA) is a primary metabolite of nicotinamide produced by the action of nicotinamide N-methyltransferase (NNMT; ). It demonstrates antithrombotic and anti-inflammatory properties through direct action on the endothelium by a mechanism involving the prostacyclin pathway and by improving nitric oxide bioavailability. Aggressive cancer cell lines are reported to have higher levels of MNA due to increased NNMT-directed transfer of methyl groups from S-adenosyl-L-methionine to nicotinamide, implicating a role for MNA in cancer cell metabolism.

Uses
1-Methylnicotinamide chloride may be used as a standard in the quantification of 1-methylnicotinamide in urine samples using ion pairing reverse-phase high performance liquid chromatography (RP-HPLC).
General Description
1-Methylnicotinamide (MNA) is a primary metabolite of nicotinamide produced mainly by nicotinamide N-methyltransferase (NNMT) and exhibits antithrombotic and anti-inflammatory effects.
Biochem/physiol Actions
1-Methylnicotinamide (MNA) is a primary metabolite of nicotinamide produced mainly by nicotinamide N-methyltransferase (NNMT). 1-Methylnicotinamide (MNA) has been shown to have antithrombotic and anti-inflammatory effects. A recent study indicated that MNA may exert antithrombotic and anti-inflammatory effects through direct action on the endothelium, with a vasorelaxing effect by enhancement of NO bioavailability and reduction of eNOS-dependent oxidative stress. Enhanced NNMT activity is a feature of many types of cancer. How much direct involvement MNA has in the tumorigenesis associated with overexpression of NNMT is under investigation. MNA by itself increased mitochondrial Complex I activity and increased cancer cell viability in SH-SY5Y neuroblastoma cells that do not produce NNMT.
Purification Methods
