Features:

Evodiamine is a bioactive alkaloid isolated primarily from the fruit of the traditional Chinese medicinal herb Evodia rutaecarpa. Evodiamine is a natural alkaloid from Evodia rutaecarpa, a traditional Chinese medicine. It has various pharmacological activities, such as anti-inflammatory, anti-cancer, anti-microbial and metabolic regulation, but also shows hepatotoxicity and cardiotoxicity.

Evodiamine — a naturally occurring quinazolinocarboline indole alkaloid isolated mainly from the dried, immature fruit of Tetradium ruticarpum, historically known as Evodia rutaecarpa or Evodiae Fructus. It is classified as an experimental plant-derived small molecule and multitarget anticancer lead compound. Standard abbreviations include EVO, EVD and EDM. Evodiamine interacts with topoisomerases, microtubules, mitochondrial death pathways and several oncogenic signalling networks, but it is not an approved anticancer drug and has extremely poor oral bioavailability.

Primary mechanisms (ranked):

Disruption of DNA topology through inhibition or trapping of topoisomerase I and catalytic inhibition of topoisomerase II, producing replication stress, DNA damage signalling and cell-cycle arrest.
Mitotic disruption through altered tubulin polymerization and microtubule dynamics, commonly producing G2/M or mitotic arrest.
Induction of mitochondrial and endoplasmic-reticulum-associated apoptosis through mitochondrial membrane depolarization, Bax/Bcl-2 modulation, cytochrome-c release and caspase activation.
Suppression of PI3K/AKT/mTOR and related survival signalling, with context-dependent activation of stress MAPKs including JNK and p38.
ROS elevation and oxidative stress that amplify mitochondrial dysfunction, DNA damage and apoptosis in susceptible cancer cells.
Suppression of NF-κB and STAT3 transcriptional signalling, reducing anti-apoptotic, inflammatory, angiogenic and metastatic gene expression.
Inhibition of HSP70-mediated proteostasis and survival of cancer stem-like and chemoresistant cell populations.
Suppression of invasion, EMT, angiogenesis and immune-evasion signalling, including context-dependent reductions in MMP-9, VEGF, MUC1-C and PD-L1.
Induction of autophagy, which may be cytotoxic or cytoprotective depending on cancer type, concentration and treatment duration.

Bioavailability / PK relevance: Native evodiamine is poorly water-soluble, has limited gastrointestinal absorption, undergoes extensive metabolism and has exceptionally low systemic oral bioavailability in animal models; an approximate oral bioavailability of 0.1% has been reported in rats. Nanoparticles, phospholipid complexes, solid dispersions, liposomes and structural analogues improve exposure experimentally, but no optimized formulation has established clinical anticancer efficacy.

In-vitro vs systemic exposure relevance: Most anticancer experiments use micromolar evodiamine concentrations maintained for hours to days. These exposures substantially exceed the plasma concentrations expected after conventional oral evodiamine because of its poor dissolution, absorption and systemic availability. Direct translation of common cell-culture concentrations to oral supplementation is therefore not pharmacokinetically supported.

Clinical evidence status: Preclinical only. Anticancer evidence consists primarily of cell-culture studies, xenografts and other animal models. No established randomized clinical trial evidence demonstrates efficacy against cancer, and evodiamine has no FDA, EMA or Health Canada approval as an anticancer therapy. Hepatotoxicity, cardiotoxicity, formulation limitations and uncertain human pharmacokinetics remain major development barriers.

Evodiamine Mechanistic Profile

Rank	Pathway / Axis	Cancer Cells	Normal Cells	TSF	Primary Effect	Notes / Interpretation
1	Topoisomerase I and II	TOP1-DNA cleavage complexes ↑; TOP1 and TOP2 activity ↓; DNA damage ↑	DNA damage possible ↑ at sufficient exposure	R–G	Replication stress, DNA strand damage and growth inhibition	Evodiamine has been reported as a TOP1 poison or cleavage-complex stabilizer and as a dual TOP1/TOP2 catalytic inhibitor; the precise mode is assay-dependent.
2	Tubulin and mitotic progression	Tubulin polymerization altered; G2/M arrest ↑; mitotic arrest ↑	Mitotic toxicity possible ↑ in proliferating normal cells	R–G	Failure of mitotic progression	Microtubule disruption may explain the frequent G2/M phenotype better than TOP1 inhibition alone.
3	Mitochondrial apoptosis	Mitochondrial membrane potential ↓; Bax ↑; Bcl-2 and Bcl-xL ↓; cytochrome c ↑; caspase-9 and caspase-3 ↑	Mitochondrial toxicity possible ↑ (dose-dependent)	R–G	Intrinsic apoptotic cell death	One of the most consistently reproduced downstream effects across cancer models.
4	PI3K AKT mTOR survival signalling	PI3K ↓; p-AKT ↓; mTOR signalling ↓	Variable or insufficiently characterized	R–G	Reduced survival, proliferation and therapy resistance	Observed in glioma, pancreatic, hepatic, prostate and other cancer models; not necessarily a direct molecular target.
5	Mitochondrial ROS and oxidative stress	ROS ↑; oxidative damage ↑; mitochondrial dysfunction ↑	Oxidative injury possible ↑ at toxic concentrations	P–R	Amplification of apoptosis and cell-cycle arrest	ROS dependence is model-dependent; antioxidant rescue has been reported in selected systems. This is not evidence of cancer-selective oxidative stress in humans.
6	Stress MAPK signalling	JNK ↑; p38 ↑; ERK variable	Variable or insufficiently characterized	P–R	Stress signalling, mitotic arrest and apoptosis	MAPK direction varies by cell type and exposure; JNK activation is mechanistically important in several colorectal and mitochondrial-apoptosis models.
7	NF-κB inflammatory and survival signalling	IKK activity ↓; IκBα degradation ↓; NF-κB activation ↓; COX-2 ↓; anti-apoptotic proteins ↓	Inflammatory signalling ↓ (context-dependent)	R–G	Reduced survival, inflammation, invasion and chemoresistance	NF-κB suppression can sensitize experimental tumors to gemcitabine and other cytotoxic treatments.
8	SHP-1 STAT3 axis	SHP-1 ↑; STAT3 Tyr705 phosphorylation ↓; cyclin D1, survivin, XIAP, VEGF and MMP-9 ↓	Insufficiently characterized	R–G	Reduced proliferation, angiogenesis and survival	Strongly demonstrated in hepatocellular carcinoma models but may not generalize uniformly across cancers.
9	HSP70 proteostasis	HSP70 function ↓; proteotoxic stress ↑; cancer stem-cell survival ↓	Potential proteostasis toxicity (dose-dependent)	R–G	Apoptosis of bulk, stem-like and drug-resistant cancer populations	HSP70 has been proposed as a direct functional target, providing a potential mechanism against chemoresistant subpopulations.
10	Autophagy	LC3-II and autophagosome formation ↑	Insufficiently characterized	G	Context-dependent cell death or survival adaptation	Autophagy may contribute to cytotoxicity in some models but protect tumor cells in others; combination with autophagy inhibition can enhance activity experimentally.
11	EMT invasion and angiogenesis	EMT ↓; MMP-2 and MMP-9 ↓; VEGF ↓; migration and invasion ↓	Endothelial angiogenic activity may ↓	G	Reduced metastatic and angiogenic phenotype	Primarily preclinical and often secondary to suppression of NF-κB, STAT3, AKT or β-catenin signalling.
12	MUC1-C PD-L1 immune-evasion axis	MUC1-C ↓; PD-L1 ↓; CD8-positive T-cell activity ↑ in immunocompetent models	Normal immune effects uncertain	G	Reduced immune evasion	Promising but model-specific evidence; no clinical immunotherapy combination data are available.
13	Chemosensitization	Resistance signalling ↓; apoptosis with gemcitabine, erlotinib or other agents ↑	Combination toxicity uncertain	G	Enhanced experimental treatment response	Combination effects remain preclinical and cannot currently support adjunct use in patients.
14	Clinical Translation Constraint	Systemic exposure after oral dosing very low	Hepatic and cardiac injury possible; CYP-mediated interactions possible	G	Limits clinical feasibility and therapeutic index	Poor solubility, approximately 0.1% rat oral bioavailability, extensive metabolism, uncertain human dosing, hepatotoxicity and cardiotoxicity prevent direct translation of micromolar in-vitro findings.

TOP1, Topoisomerase I: Click to Expand ⟱

Type:

Topoisomerase I (TOP1) is an essential nuclear enzyme involved in relieving DNA supercoiling during replication and transcription.
• Elevated TOP1 expression has been observed in several tumor types, such as colorectal, ovarian, breast, and lung cancers.
• Increased TOP1 levels may correlate with higher proliferation rates, as actively dividing tumor cells require efficient relief of DNA.

• In some cancers, high TOP1 expression has been associated with aggressive tumor behavior, higher grade, and potentially poorer clinical outcomes. This may be due in part to increased proliferation and/or a greater propensity for genomic instability.
• In other contexts, TOP1 expression might indicate sensitivity to TOP1-targeted therapies. For example, tumors with high TOP1 activity may respond better to chemotherapeutic agents (e.g., irinotecan) that target the enzyme, potentially improving outcomes when appropriate treatment is administered.

TOP1 is a critical enzyme in maintaining DNA integrity whose expression in cancers can reflect tumor proliferation and genomic instability. While high TOP1 expression is often associated with aggressive tumor behavior and poorer prognosis in several cancer types, it also has therapeutic relevance because tumors with elevated TOP1 may be more sensitive to TOP1 inhibitors.
