Features: polyphenol
Found in red grapes and products made with grapes.
Resveratrol is a polyphenol compound found in various plant species, including grapes, berries, and peanuts.
• Anti-inflammatory effects, Antioxidant effects:
- Antiplatelet aggregation for stroke prevention
- BioAvialability use piperine
- some sources may use Japanese knotweed roots (Reynoutria Japonica - root) as source which might contain Emodin (laxative)
-known as Nrf2 activator, both in cancer and normal cells. Which raises controversity of use in ROS↑ therapies. Interestingly there are reports of NRF2↑ and ROS↑ in cancer cells. This raises the question of if it is a chemosensitizer. However other reports indicate NRF2 droping with Res, indicating it maybe a chemosenstizer.
- RES is also considered to be them most effective natural SIRT1↑ -activating compound (STACs).

However, in the presence of certain metals, such as copper or iron, resveratrol can undergo a process called Fenton reaction, which can lead to the generation of reactive oxygen species (ROS). The pro-oxidant effects of resveratrol are often observed at high concentrations, typically above 50-100 μM, and in the presence of certain metals or other pro-oxidant agents. In contrast, the antioxidant effects of resveratrol are typically observed at lower concentrations, typically below 10-20 μM.

Clinical trials have used doses ranging from 150 mg to 5 grams per day. Lower doses (< 1 g/day) are often well-tolerated, but higher doses might be necessary for therapeutic effects and can be associated with side effects.

BioAv poor: min 5uM/L required for chemopreventive effects, but 25mg Oral only yeilds 20nM. co-administration of piperine

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Reactive oxygen species (ROS) ↑ ROS (dose- & context-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation Resveratrol can act as a pro-oxidant in cancer cells while functioning as an antioxidant in normal cells
2 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Driver Execution of intrinsic apoptosis Mitochondrial dysfunction and apoptosis follow ROS elevation in cancer cells
3 SIRT1 / AMPK axis ↑ AMPK; context-dependent SIRT1 modulation ↑ SIRT1 / ↑ AMPK Driver Metabolic stress signaling Resveratrol modulates energy-sensing pathways affecting survival and metabolism
4 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Secondary Growth and anabolic inhibition Downregulation of growth signaling contributes to cytostasis and apoptosis sensitization
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of survival and inflammatory transcription NF-κB inhibition contributes to reduced proliferation and invasion
6 Cell cycle regulation ↑ G1/S or G2/M arrest ↔ largely spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling disruption
7 HIF-1α / VEGF axis ↓ HIF-1α; ↓ VEGF ↔ minimal Secondary Anti-angiogenic pressure Interference with hypoxia-driven adaptation and angiogenesis

Type:
The selectivity of cancer products (such as chemotherapeutic agents, targeted therapies, immunotherapies, and novel cancer drugs) refers to their ability to affect cancer cells preferentially over normal, healthy cells. High selectivity is important because it can lead to better patient outcomes by reducing side effects and minimizing damage to normal tissues.

Achieving high selectivity in cancer treatment is crucial for improving patient outcomes. It relies on pinpointing molecular differences between cancerous and normal cells, designing drugs or delivery systems that exploit these differences, and overcoming intrinsic challenges like tumor heterogeneity and resistance

Factors that affect selectivity:
1. Ability of Cancer cells to preferentially absorb a product/drug
-EPR-enhanced permeability and retention of cancer cells
-nanoparticle formations/carriers may target cancer cells over normal cells
-Liposomal formations. Also negatively/positively charged affects absorbtion

2. Product/drug effect may be different for normal vs cancer cells
- hypoxia
- transition metal content levels (iron/copper) change probability of fenton reaction.
- pH levels
- antiOxidant levels and defense levels

3. Bio-availability
