Features:

Sanguinarine (SANG) — a benzophenanthridine alkaloid isolated primarily from Sanguinaria canadensis (bloodroot) and other Papaveraceae species. Potent redox-active, DNA-intercalating phytochemical studied extensively in preclinical oncology.

Primary mechanisms (conceptual rank):
1) ROS generation → mitochondrial apoptosis
2) NF-κB / STAT3 inhibition (anti-survival signaling)
3) Cell-cycle arrest (G0/G1 or G2/M depending on model)
4) MAPK modulation (JNK activation; ERK suppression context-dependent)
5) Epigenetic/DNA interaction effects

Bioavailability / PK relevance: Limited human PK data; rapid reactivity and protein binding likely restrict systemic exposure. Toxicity (oral mucosal injury, cytotoxicity) limits therapeutic window.

In-vitro vs oral exposure: Many anti-cancer effects occur at micromolar concentrations unlikely achievable systemically via safe oral dosing (qualifier: high concentration only for direct cytotoxicity).

Clinical evidence status: Preclinical oncology only; no validated RCT cancer indication. Safety concerns limit development.

Extracted from bloodroot plant from whose scientific name, Sanguinaria canadensis, its name is derived; the Mexican prickly poppy; Chelidonium majus; and Macleaya cordata.

Sanguinarine — Cancer vs Normal Cell Pathway Map

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 ROS / Mitochondrial redox stress ↑ (primary; dose-dependent) ↑ (high concentration only) P/R Oxidative stress → apoptosis Central mechanism; rapid ROS generation drives mitochondrial membrane depolarization and cytochrome c release.
2 Intrinsic apoptosis (Bax↑, Bcl-2↓, caspases) ↑ ↑ (high concentration only) R/G Programmed cell death Often ROS-dependent; cancer cells show greater susceptibility due to higher basal oxidative stress.
3 NF-κB signaling ↓ ↓ (context-dependent) R/G Reduced pro-survival transcription Suppresses inflammatory and anti-apoptotic gene expression; contributes to anti-proliferative effect.
4 STAT3 axis ↓ ↔ R/G Reduced survival signaling STAT3 inhibition reported in multiple tumor models; linked to decreased proliferation and invasion.
5 MAPK (JNK↑ / ERK↓ context-dependent) ↑ JNK; ↓ ERK ↔ / ↑ stress (high dose) P/R Stress-activated apoptosis signaling JNK activation promotes apoptosis; ERK suppression reduces proliferation.
6 Cell Cycle (Cyclin D1, CDK regulation) ↓ proliferation ↔ G G0/G1 or G2/M arrest Checkpoint enforcement varies by tumor type and dose.
7 NRF2 axis ↓ (overwhelmed by ROS; context-dependent) ↑ (adaptive; low dose) R/G Redox defense modulation Low dose may activate adaptive NRF2; higher doses override antioxidant defenses in cancer cells.
8 Ca²⁺ / ER stress ↑ (stress-dependent) ↑ (high concentration only) P/R ER-mitochondrial stress coupling Calcium dysregulation contributes to apoptosis cascade.
9 Ferroptosis ↑ (lipid ROS-linked; investigational) ↔ R/G Lipid peroxidation stress ROS-driven lipid damage suggests ferroptosis overlap but not primary established mechanism.
10 HIF-1α ↓ (model-dependent) ↔ G Reduced hypoxia adaptation Reported suppression in some tumor contexts.
11 Clinical Translation Constraint ↓ (constraint) ↓ (constraint) — Toxicity + limited PK data Oral toxicity and narrow therapeutic index limit systemic development.

Type:
Eph receptors and their Eph receptor-interacting (ephrin) ligands together form an important cell communication system with diverse roles.
High EPHB4 expression correlates with advanced prostate cancer stage and poor outcome.
EphB4 is often upregulated in cancer, and its expression may be linked to tumor progression and poor prognosis.
