Not every case of left arm numbness is dangerous
Evidence is limited
By blocking NNMT, 5-Amino-1MQ prevents nicotinamide methylation, allowing NAD+ levels to rise and methyl groups to remain available for histone methylation and other epigenetic processes
It is suitable for extended or high-volume experiments, including multi-phase studies in cell cultures or animal models of fat metabolism
Those getting prescribed injections from their doctor are likely to only need them once every few months at a very high dosage which is not meant to be used weekly or daily
Reported applications include NNMT enzyme inhibition assays measuring 1-methylnicotinamide formation or S-adenosylhomocysteine release, intracellular target-engagement assays in differentiated 3T3-L1 adipocytes where 5-Amino-1MQ reduced intracellular 1-methylnicotinamide with an EC near 2.3 M (Neelakantan et al., Biochem Pharmacol, 2018), membrane permeability and Caco-2 transport characterisation, methyltransferase selectivity panels covering COMT, DNMT1 and PRMT3, and rodent studies of NNMT inhibition in adipose tissue and liver following the antisense knockdown work of Kraus and colleagues (Nature, 2014)
