NNMT inhibition increases cellular concentrations of both substrates that the enzyme would otherwise consume: SAM (the universal methyl donor) and nicotinamide (the NAD + salvage precursor)
Increased incidences of early resorptions, ossification delays, and developmental variations, as well as decreased fetal body weights were observed in rats in the presence of maternal toxicity, at systemic exposures (AUC) approximately 10 times higher than exposure at the approved human dose of PAXLOVID
