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

Phytochemicals (natural plant-derived compounds) that may affect CSCs:
Curcumin
— suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Resveratrol
— shown to reduce CSC populations and sphere formation in multiple models.
Sulforaphane (from broccoli sprouts)
— reported to inhibit CSC properties and pathways; active in vitro and in vivo.
EGCG (epigallocatechin-3-gallate, green tea)
— reduces CSC markers and sphere formation in several cancer types.
Quercetin
— reported to inhibit CSC proliferation, self-renewal and invasiveness (breast, endometrial, others).
Berberine
— shown to suppress CSC “stemness” and reduce tumorigenic properties in multiple models.
Genistein (soy isoflavone)
— decreases CSC markers, sphere formation and stemness signaling in prostate/breast/other models.
Honokiol (Magnolia bark)
— shown to eliminate or suppress CSC-like populations in oral, colon, glioma models.
Luteolin
— inhibits stemness/EMT and reduces CSC markers and self-renewal in breast, prostate and other models.
Withaferin A (from Withania somnifera / ashwagandha)
— multiple preclinical reports show WA targets CSCs and reduces tumor growth/metastasis in models.
