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.

Also known as CP32.
Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death.
As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression.
Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy.
Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent.
On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer.
Procaspase-3 is a apoptotic marker protein.
Prognostic significance:
• High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers.
• Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers.
