CUR, Curcumin: Click to Expand ⟱
Features:
Curcumin is the main active ingredient in Tumeric. Member of the ginger family.Curcumin is a polyphenol extracted from turmeric with anti-inflammatory and antioxidant properties.
- Has iron-chelating, iron-chelating properties. Ferritin. But still known to increase Iron in Cancer cells.
- GSH depletion in cancer cells, exhaustion of the antioxidant defense system. But still raises GSH↑ in normal cells.
- Higher concentrations (5-10 μM) of curcumin induce autophagy and ROS production
- Inhibition of TrxR, shifting the enzyme from an antioxidant to a prooxidant
- Strong inhibitor of Glo-I, , causes depletion of cellular ATP and GSH
- Curcumin has been found to act as an activator of Nrf2, (maybe bad in cancer cells?), hence could be combined with Nrf2 knockdown
-may suppress CSC: suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Clinical studies testing curcumin in cancer patients have used a range of dosages, often between 500 mg and 8 g per day; however, many studies note that doses on the lower end may not achieve sufficient plasma concentrations for a therapeutic anticancer effect in humans.
• Formulations designed to improve curcumin absorption (like curcumin combined with piperine, nanoparticle formulations, or liposomal curcumin) are often employed in clinical trials to enhance its bioavailability.

-Note half-life 6 hrs.
BioAv is poor, use piperine or other enhancers

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Driver Suppression of survival and inflammatory transcription NF-κB is a primary, repeatedly validated curcumin target explaining pleiotropic downstream effects
2 STAT3 signaling ↓ STAT3 phosphorylation / activity ↔ or mild suppression Driver Loss of pro-survival and proliferative signaling STAT3 inhibition contributes to growth arrest, apoptosis sensitization, and reduced cytokine signaling in tumors
3 Reactive oxygen species (ROS) ↑ ROS (dose- & context-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation Curcumin can act as a pro-oxidant in cancer cells with high basal stress while acting antioxidant in normal cells
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Driver Execution of intrinsic apoptosis Mitochondrial dysfunction and caspase activation occur downstream of NF-κB/STAT3 and ROS effects
5 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ or adaptive suppression Secondary Reduced growth and anabolic signaling AKT/mTOR inhibition contributes to growth suppression and autophagy induction in cancer cells
6 Autophagy ↑ autophagy (protective or pro-death) ↑ adaptive autophagy Secondary Stress adaptation vs cell death Autophagy may be cytoprotective or cooperate with apoptosis depending on context and dose
7 HIF-1α / VEGF hypoxia–angiogenesis axis ↓ HIF-1α; ↓ VEGF ↔ minimal effect Secondary Anti-angiogenic pressure Suppression of hypoxia-driven transcription limits angiogenesis and tumor adaptation
8 Cell cycle regulation ↑ G2/M or G1 arrest ↔ largely spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling and epigenetic effects rather than direct CDK inhibition
9 Migration / invasion (EMT, MMP axis) ↓ migration & invasion ↔ Phenotypic Anti-metastatic phenotype Reduced EMT markers and protease activity limit invasive behavior
10 Epigenetic regulation (p300/CBP HAT activity) ↓ histone acetylation ↔ modest Secondary Transcriptional reprogramming Curcumin modulates chromatin via HAT inhibition rather than classic HDAC inhibition


RadioS, RadioSensitizer: Click to Expand ⟱
Source:
Type:
A radiosensitizer is an agent that makes cancer cells more sensitive to the damaging effects of radiation therapy. By using a radiosensitizer, clinicians aim to enhance the effectiveness of radiation treatment by either increasing the damage incurred by tumor cells or by interfering with the cancer cells’ repair mechanisms. This can potentially allow for lower doses of radiation, reduced side effects, or improved treatment outcomes.
Pathways that help Radiosensitivity: downregulating HIF-1α, increase SIRT1, Txr

List of Natural Products with radiosensitizing properties:
-Curcumin:modulate NF-κB, STAT3 and has been shown in preclinical studies to enhance the effects of radiation by inhibiting cell survival pathways.
-Resveratrol:
-EGCG:
-Quercetin:
-Genistein:
-Parthenolide:
