Features:
Antioxidant found in blueberries, cranberries and grapes.
Pterostilbene (trans-3,5-dimethoxy-40-hydroxystilbene) is a naturally occurring stilbene, found mainly in blueberries and grapes. It is a dimethylated derivative of resveratrol with comparable antioxidant, anti-inflammatory and anticarcinogenic properties [26].
-more bioavailable than resveratrol
-Antioxidant activity: Reduces reactive oxygen species and lipid peroxidation
-Anti-inflammatory: Downregulates pro-inflammatory cytokines- IL-1β, TNF-α, NF-κB
-Amyloid pathology:inhibits Aβ aggregation and promotes clearance- Aβ, APP, BACE1
-Reduces hyperphosphorylation of tau protein
-Inhibits histone deacetylases (HDACs)
-Increases acetylcholine by inhibiting acetylcholinesterase
-Sirtuin activation

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 SIRT1 / AMPK metabolic sensing ↑ AMPK; context-dependent SIRT1 modulation ↑ SIRT1 / ↑ AMPK Driver Energy-stress signaling Pterostilbene strongly engages energy-sensing pathways due to high bioavailability
2 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Driver Growth and survival inhibition AKT/mTOR suppression explains cytostatic and pro-apoptotic effects in cancer cells
3 Reactive oxygen species (ROS) ↑ ROS (mild, dose-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation More balanced redox profile than resveratrol; weaker pro-oxidant behavior
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Secondary Execution of apoptosis Mitochondrial apoptosis follows metabolic and redox stress
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of inflammatory survival programs NF-κB inhibition contributes to anti-invasive and chemosensitizing effects
6 Cell cycle regulation ↑ G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream metabolic and signaling effects
7 NRF2 antioxidant response ↑ NRF2 (adaptive) ↑ NRF2 (protective) Adaptive Redox compensation NRF2 activation contributes to stress buffering rather than primary cytotoxicity

Type:
For many drugs, the half-life is the time it takes for half of the drug’s active substance to be eliminated from the bloodstream.
In medicine, knowing a drug’s half-life helps in designing treatment regimens that reduce adverse effects.
