Notes: Spermidine is an endogenous polyamine.{58623} It is formed from putrescine by spermidine synthase. Spermidine (25 µM) inhibits the activity of the human inward-rectifying potassium channel Kir2.3 in a patch-clamp assay.{58624} It induces autophagy in HeLa cells when used at a concentration of 100 µM and increases the lifespan of D. melanogaster, yeast, and C. elegans.{58634} Spermidine (30 mM in the drinking water) reduces demyelination of the optic nerve and disease severity in a mouse model of experimental autoimmune encephalomyelitis (EAE).{58625} It reduces increases in blood pressure, left ventricular posterior wall thickness, and heart weight in salt-sensitive Dahl rats fed a high-salt diet, a model of hypertension-induced congestive heart failure.{58633} Formulations containing spermidine have been used as dietary supplements.
