Juglone / TumCCA Cancer Research Results

JG, Juglone: Click to Expand ⟱
Features:
Found in roots, leaves, nut-hulls, bark and wood of walnut trees.
Juglone (5-hydroxy-1,4-naphthoquinone)
Juglans nigra refers to the black walnut tree, which is one of the most well-known sources of juglone
-Research has focused on the hulls (the green outer covering of the walnut) because they have the highest concentrations.
-Fresh hulls can contain juglone levels in the range of approximately 1–5% of the dry weight

-Juglone can redox cycle to generate reactive oxygen species (ROS).
-Increasing Bax, decreasing Bcl‑2, caspase activation, and MMP depolarization.
-Modulation of MAPK pathways (including ERK, JNK, and p38)
-May inhibit NF‑κB signaling
-Cause DNA damage or stress that, in turn, leads to p53 pathway activation— Pin1 Inhibition
–Pin1, a peptidyl-prolyl cis/trans isomerase, is frequently overexpressed in cancer.

-ic50 maybe 5-10uM
-For matching 5uM, crude estimate is 5mg consumption of juglone required which might be 1.5 g of black walnut hull material

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Redox cycling (quinone–semiquinone system) ↑↑ ROS Oxidative stress overload Juglone can act as a redox-cycling quinone; ROS elevation is a dominant upstream driver in multiple cancer models (ref)
2 Thiol buffering (GSH depletion) ↓ GSH Loss of redox buffering In HL-60 leukemia cells, juglone induces ROS and explicitly depletes GSH; antioxidants block downstream apoptosis markers (ref)
3 Mitochondrial integrity (ΔΨm) ↓ ΔΨm Mitochondrial dysfunction In LNCaP prostate cancer cells, juglone decreases mitochondrial potential (ΔΨ) during intrinsic apoptosis (ref)
4 Intrinsic apoptosis (Caspase-9 → Caspase-3) ↑ Caspase-9/3 activation Programmed cell death Same LNCaP evidence base: intrinsic apoptosis with activation of caspases 3 and 9 is reported for juglone (ref)
5 DNA damage / genotoxic stress ↑ DNA damage Checkpoint activation and death signaling Juglone is reported to have genotoxic effects (DNA damage) in melanoma models, consistent with ROS-driven injury (ref)
6 p53 stress response ↑ p53 pathway (activation) Cell-cycle arrest / apoptosis cooperation Human liver cancer model: juglone drives apoptosis and autophagy via a ROS-mediated p53 pathway (in vitro and in vivo) (ref)
7 MAPK stress pathways (JNK / p38) ↑ JNK / ↑ p38 Pro-death stress signaling Mechanistic synthesis notes juglone induces ROS and activates JNK and p38 MAPK, contributing to cell death signaling (ref)
8 NF-κB signaling ↓ NF-κB Reduced pro-survival transcription Literature reports juglone inhibits NF-κB production/signaling in colonic cancer cell contexts (noted as prior work) (ref)
9 PI3K–AKT survival pathway ↓ PI3K / ↓ p-AKT Survival pathway suppression NSCLC: juglone increases ROS and inhibits PI3K/Akt signaling; NAC (ROS scavenger) attenuates apoptosis and pathway changes (ref)
10 Cell cycle control ↑ arrest Proliferation blockade NSCLC: juglone arrests the cell cycle alongside ROS rise and apoptosis marker changes (ref)
11 Autophagy ↑ autophagy (stress-associated) Stress adaptation / death crosstalk Juglone induces both apoptosis and autophagy in cancer cells via MAPK pathway modulation (with ROS-MAPK coupling) (ref)
12 Angiogenesis signaling (VEGF) ↓ VEGF Reduced vascular support Pancreatic cancer cell lines: juglone reduces VEGF gene expression (and other metastasis/angiogenesis-related genes) at sub-IC50 exposure (ref)

Type:
Tumor cell cycle arrest refers to the process by which cancer cells stop progressing through the cell cycle, which is the series of phases that a cell goes through to divide and replicate. This arrest can occur at various checkpoints in the cell cycle, including the G1, S, G2, and M phases. S, G1, G2, and M are the four phases of mitosis.
