Product Introduction

Spermidine is an endogenous polyamine that regulates core cellular homeostasis. Mechanistically, it induces autophagy via multiple conserved pathways:
Inhibits acetyltransferase EP300, reducing protein acetylation and activating autophagy‑related genes (Atg5, Atg7, LC3, Atg12).
Modulates mTOR signaling and activates the ULK1/2‑Atg13‑FIP200 complex to initiate autophagosome formation.
Promotes hypusination of eIF5A, supporting autophagy flux and mitochondrial function.
Enhances FoxO3‑Atg signaling and HDAC4 nuclear translocation to sustain cytoprotective autophagy.
These actions clear damaged organelles and protein aggregates, reduce oxidative stress, stabilize nucleic acids, support membrane integrity, and maintain metabolic efficiency.
