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)
Several factors cause this variability
Side effects to Vitamin B12 are SO rare that they cannot be estimated from current data (in other words, less than 1 in 10'000)
