Background

Spermidine-d₆ is intended for use as an internal standard for the quantification of spermidine by GC- or LC-MS. Spermidine is an endogenous polyamine.¹ It is formed from putrescine by spermidine synthase. Spermidine (25 µM) inhibits the activity of the human inward-rectifying potassium channel K_ir2.3 in a patch-clamp assay.¹ 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.² 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).³ 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.⁴ Formulations containing spermidine have been used as dietary supplements.
