Polyamines are molecules derived from ornithine (Orn) (i.e., putrescine, spermine, spermidine) or arginine (Arg) (i.e., agmatine). While ornithine decarboxylase is responsible for ornithine degradation and spermidine production, cSAT and nSAT transform spermidine to N1-acetylspermidine (N1-AcSpdn). These molecules are involved in many critical processes such as cell proliferation, nucleic acid synthesis, and cytoprotection from oxidative stress1. Several studies have evidenced that polyamine metabolism is frequently increased in cancer2 which can fuel tumor progression3 and favor immune escape4. Elevated levels of polyamines in sera of cancer patients have been demonstrated to correlate with poor prognosis.
