Features:
Plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone) is a naturally occurring naphthoquinone derivative.

–Plumbagin can undergo redox cycling to generate reactive oxygen species (ROS)
-apototosis, activation of caspases, modulation of Bax, Bcl‑2, loss of MMP.
-Cell cycle arrest in cancer cells, often at the G0/G1, or G2/M phases.
-May inhibit NF‑κB activation
– MAPK Pathways
– PI3K/Akt Pathway
-Downregulation of (VEGF) and matrix metalloproteinases (MMPs).

-Seems capable of raising ROS in normal and cancer cells (#2004)

-ic50 cancer cells 1-10uM, normal cells >10uM

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Oxidative stress (redox cycling) ↑ ROS Upstream cytotoxic trigger Plumbagin induces ROS; ROS generation is causally linked to cell death in cancer models (ref)
2 Mitochondrial integrity (ΔΨm) ↓ ΔΨm Mitochondrial dysfunction Loss of mitochondrial membrane potential occurs during plumbagin-induced apoptotic progression (ref)
3 Intrinsic apoptosis (caspase cascade) ↑ caspase-dependent apoptosis Programmed cell death Plumbagin triggers apoptosis in leukemia and solid tumor cells; antioxidant rescue attenuates killing (ref)
4 NF-κB signaling ↓ NF-κB activation Reduced pro-survival / inflammatory transcription Demonstrates plumbagin suppresses NF-κB signaling in tumor/immune contexts (direction explicitly shown) (ref)
5 STAT3 signaling ↓ STAT3 phosphorylation Reduced survival & proliferation signaling Plumbagin suppresses constitutive and inducible STAT3 phosphorylation in cancer cells (ref)
6 PI3K–AKT–mTOR signaling ↓ PI3K/AKT/mTOR activity Survival pathway suppression Plumbagin inhibits PI3K/AKT/mTOR signaling in cancer cells with linked apoptosis/autophagy outcomes (ref)
7 Autophagy program ↑ autophagy Stress response (context-dependent role) Plumbagin induces autophagy alongside apoptosis; pathway involvement (p38, PI3K/AKT/mTOR) is demonstrated (ref)
8 Stress MAPK (p38 MAPK) ↑ p38 activation Stress signaling amplification p38 MAPK activation is implicated in plumbagin-driven apoptosis/autophagy signaling in cancer cells (ref)
9 Cell cycle control ↑ G2/M (or S–G2/M) arrest Proliferation blockade Plumbagin induces checkpoint arrest with changes in cyclins/CDKs consistent with growth inhibition (ref)
10 Death receptor axis (TRAIL receptors DR4/DR5) ↑ DR4/DR5 expression Sensitizes to TRAIL-mediated killing Plumbagin increases DR4/DR5 and enhances TRAIL killing; NAC blocks both ROS and receptor upregulation (ref)
11 EMT / invasion programs ↓ EMT (anti-invasive) Reduced metastasis-related phenotype Plumbagin suppresses epithelial–mesenchymal transition and stemness-related markers in cancer cells (ref)
12 Angiogenesis signaling (VEGFR2/VEGF-driven endothelial responses) ↓ angiogenesis signaling / function Anti-angiogenic effect Plumbagin inhibits tumor angiogenesis via interference with VEGFR2-mediated signaling in endothelial/tumor models (ref)

Type:
BMI1 (B cell-specific Moloney murine leukemia virus integration site 1) is a protein that plays a crucial role in the regulation of cell growth, differentiation, and survival. It is a key component of the Polycomb repressive complex 1 (PRC1), which is involved in the silencing of genes through histone modification.
Overexpression of BMI1 has been observed in many types of cancer, and it is often associated with poor prognosis and reduced survival rates.
