To this end, we synthesized a number of permethylated quinolinium analogues[17] guided by in silico calculation of partition coefficient (clogP).[26] Addition of hydrophobic methyl group substitutions around the quinolinium scaffold (previously shown to negatively impact NNMT inhibitory activity)[17] only slightly improved membrane permeability via passive transport as indicated by the low, but non-zero, permeability values for 1,8-diMQ and 1,2,4,8-tetraMQ (Table 1)

These factors suggest starting slightly higher than the minimum effective clinical dose to account for real-world variability

Its unique chemical makeup is what allows it to slip through cell membranes and interact directly with the NNMT enzyme
