However, glucagon in CNS decreases food intake, increases energy expenditure via brown fat thermogenesis, decreases fat accumulation via lipolysis and lipid synthesis inhibition, improves cardiac performance, inhibits gastric motility, and stimulates autophagy
A translational review on NNMT inhibitor clinical development ( Emerging opportunities for NNMT inhibitor clinical translation , ScienceDirect, 2026) points out that alternative routes like polyamine biosynthesis could compensate for the raised SAM, and that partial rather than total inhibition might even be preferable specifically to avoid triggering those compensatory mechanisms from a chronically imbalanced SAM/SAH ratio
