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


PI3K, Phosphatidylinositide-3-Kinases: Click to Expand ⟱

Type:
Phosphatidylinositol 3-kinase (PtdIns3K or PI3K) is a family of enzymes that play a crucial role in cell signaling pathways, particularly in the regulation of cell growth, survival, and metabolism. The PI3K pathway is one of the most frequently altered pathways in human cancer. Inhibition of the PI3K pathway has been explored as a therapeutic strategy for cancer treatment. Several PI3K inhibitors have been developed and are currently being tested in clinical trials. These inhibitors can target specific components of the pathway, such as PI3K, AKT, or mTOR.

Class I phosphoinositide 3-kinase (PI3K)
Class III PtdIns3K
In contrast to the class III PtdIns3K as a positive regulator of autophagy, class I PI3K-AKT signaling has an opposing effect on the initiation of autophagy.

PI3K inhibitors include:
-Idelalisib , Copanlisib, Alpelisib
-LY294002?
-Wortmannin: potent PI3K inhibitor, has some associated toxicity.
-Quercetin:
-Curcumin
-Resveratrol
-Epigallocatechin Gallate (EGCG)
