| 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):
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

| Reactive oxygen species (ROS) are highly reactive molecules that contain oxygen and can lead to oxidative stress in cells. They play a dual role in cancer biology, acting as both promoters and suppressors of cancer. ROS can cause oxidative damage to DNA, leading to mutations that may contribute to cancer initiation and progression. So normally you want to inhibit ROS to prevent cell mutations. However excessive ROS can induce apoptosis (programmed cell death) in cancer cells, potentially limiting tumor growth. Chemotherapy typically raises ROS. -mitochondria is the main source of reactive oxygen species (ROS) (and the ETC is heavily related) ROS Homeostasis in Cancer Cells and Its Potential as a Therapeutic Target "Reactive oxygen species (ROS) are two electron reduction products of oxygen, including superoxide anion, hydrogen peroxide, hydroxyl radical, lipid peroxides, protein peroxides and peroxides formed in nucleic acids 1. They are maintained in a dynamic balance by a series of reduction-oxidation (redox) reactions in biological systems and act as signaling molecules to drive cellular regulatory pathways." "During different stages of cancer formation, abnormal ROS levels play paradoxical roles in cell growth and death 8. A physiological concentration of ROS that maintained in equilibrium is necessary for normal cell survival. Ectopic ROS accumulation promotes cell proliferation and consequently induces malignant transformation of normal cells by initiating pathological conversion of physiological signaling networks. Excessive ROS levels lead to cell death by damaging cellular components, including proteins, lipid bilayers, and chromosomes. Therefore, both scavenging abnormally elevated ROS to prevent early neoplasia and facilitating ROS production to specifically kill cancer cells are promising anticancer therapeutic strategies, in spite of their contradictoriness and complexity." "ROS are the collection of derivatives of molecular oxygen that occur in biology, which can be categorized into two types, free radicals and non-radical species. The non-radical species are hydrogen peroxide (H 2O 2 ), organic hydroperoxides (ROOH), singlet molecular oxygen ( 1 O 2 ), electronically excited carbonyl, ozone (O3 ), hypochlorous acid (HOCl, and hypobromous acid HOBr). Free radical species are super-oxide anion radical (O 2•−), hydroxyl radical (•OH), peroxyl radical (ROO•) and alkoxyl radical (RO•) [130]. Any imbalance of ROS can lead to adverse effects. H2 O 2 and O 2 •− are the main redox signalling agents. The cellular concentration of H2 O 2 is about 10−8 M, which is almost a thousand times more than that of O2 •−". "Radicals are molecules with an odd number of electrons in the outer shell [393,394]. A pair of radicals can be formed by breaking a chemical bond or electron transfer between two molecules." Recent investigations have documented that polyphenols with good antioxidant activity may exhibit pro-oxidant activity in the presence of copper ions, which can induce apoptosis in various cancer cell lines but not in normal cells. "We have shown that such cell growth inhibition by polyphenols in cancer cells is reversed by copper-specific sequestering agent neocuproine to a significant extent whereas iron and zinc chelators are relatively ineffective, thus confirming the role of endogenous copper in the cytotoxic action of polyphenols against cancer cells. Therefore, this mechanism of mobilization of endogenous copper." > Ions could be one of the important mechanisms for the cytotoxic action of plant polyphenols against cancer cells and is possibly a common mechanism for all plant polyphenols. In fact, similar results obtained with four different polyphenolic compounds in this study, namely apigenin, luteolin, EGCG, and resveratrol, strengthen this idea. Interestingly, the normal breast epithelial MCF10A cells have earlier been shown to possess no detectable copper as opposed to breast cancer cells [24], which may explain their resistance to polyphenols apigenin- and luteolin-induced growth inhibition as observed here (Fig. 1). We have earlier proposed [25] that this preferential cytotoxicity of plant polyphenols toward cancer cells is explained by the observation made several years earlier, which showed that copper levels in cancer cells are significantly elevated in various malignancies. Thus, because of higher intracellular copper levels in cancer cells, it may be predicted that the cytotoxic concentrations of polyphenols required would be lower in these cells as compared to normal cells." Majority of ROS are produced as a by-product of oxidative phosphorylation, high levels of ROS are detected in almost all cancers. -It is well established that during ER stress, cytosolic calcium released from the ER is taken up by the mitochondrion to stimulate ROS overgeneration and the release of cytochrome c, both of which lead to apoptosis.
