| Deguelin is a natural compound of isoflavonoid-derived rotenoid isolated from several plant species, including Derris trifoliata Lour and Mundulea sericea (Leguminosae) (4) Deguelin’s ability to modulate multiple signaling pathways—including PI3K/Akt, mTOR, NF-κB, HIF-1α, and MAPK While preclinical studies have utilized dosages in the approximate range of 4–8 mg/kg in animal models, these figures are specific to the experimental conditions and species used in those studies. Deguelin is a rotenoid (isoflavonoid-like botanical insecticide class) found in some Lonchocarpus / Derris species. In cancer literature it’s most often described as a mitochondrial Complex I inhibitor with downstream energy stress + survival pathway suppression (Akt/PI3K, NF-κB) and apoptosis/autophagy induction. A major caution is neurotoxicity signal: rotenoids (including deguelin) have been used in Parkinson’s disease animal models via Complex I inhibition. - Active identity: Rotenoid (deguelin) — a potent mitochondrial Complex I inhibitor with downstream energy-stress signaling (AMPK/mTOR), survival pathway suppression (Akt, NF-κB), and apoptosis/autophagy induction in cancer models; higher caution category due to rotenoid neurotoxicity signals in animal models. Deguelin — a naturally occurring rotenoid derived principally from leguminous plants in the Derris, Lonchocarpus, Tephrosia, and related genera. It is a lipophilic isoflavonoid-related botanical insecticide and experimental anticancer small molecule, commonly abbreviated Deg. Its functional identity is dominated by mitochondrial respiratory Complex I inhibition, with secondary suppression of Hsp90-dependent oncogenic proteins and PI3K/AKT, NF-κB, mTOR, HIF-1α, angiogenic, and metastatic signaling. Deguelin is not an approved anticancer drug and has a substantial translational safety concern because systemic exposure can injure dopaminergic neurons and produce Parkinsonism-like pathology in animals. Primary mechanisms (ranked):
Bioavailability / PK relevance: Deguelin is highly lipophilic and poorly suited to simple aqueous delivery. Rat pharmacokinetic studies found measurable systemic persistence and a relatively long plasma residence time, but human pharmacokinetics, oral bioavailability, therapeutic exposure targets, metabolism, and safe dosing have not been established. Formulation research has therefore focused on analogues, nanoparticles, and other delivery systems intended to improve solubility or tumor exposure. Enhanced delivery could also increase neurological and systemic toxicity. In-vitro vs systemic exposure relevance: Anticancer effects are frequently reported from low-nanomolar to several-micromolar concentrations, depending on the cell model and endpoint. Some sensitive models respond below 0.1 µM, whereas apoptosis, ROS, autophagy, or broad cytotoxicity studies commonly use approximately 1–20 µM. There is no validated human exposure range demonstrating that these concentrations can be achieved safely. Because mitochondrial Complex I inhibition occurs in normal as well as malignant tissue, systemic exposure cannot be assumed to preserve cancer selectivity. Clinical evidence status: Preclinical only. Evidence consists primarily of biochemical studies, cancer-cell experiments, xenografts, chemically induced tumor models, and rodent metastasis or chemoprevention studies. No established human anticancer trial evidence, approved indication, clinically validated dose, or accepted adjunct regimen was identified. Neurotoxicity and delivery limitations currently outweigh the strength of the efficacy evidence for clinical translation. Deguelin Mechanistic Profile

| Mitogen-activated protein kinases (MAPKs) are a group of proteins involved in transmitting signals from the cell surface to the nucleus, playing a crucial role in various cellular processes, including growth, differentiation, and apoptosis (programmed cell death). MAPK Pathways: The MAPK family includes several pathways, the most notable being: 1.ERK (Extracellular signal-Regulated Kinase): Often associated with cell proliferation and survival. 2.JNK (c-Jun N-terminal Kinase): Typically involved in stress responses and apoptosis. 3.p38 MAPK: Associated with inflammatory responses and apoptosis. Inhibitors: Targeting the MAPK pathway has become a strategy in cancer therapy. For example, BRAF inhibitors (like vemurafenib) are used in treating melanoma with BRAF mutations. Altered Expression Levels: Overexpression: Many cancers exhibit overexpression of MAPK pathway components, such as RAS, BRAF, and MEK. This overexpression can lead to increased signaling activity, promoting cell proliferation and survival. Downregulation: In some cases, negative regulators of the MAPK pathway (e.g., MAPK phosphatases) may be downregulated, leading to enhanced MAPK signaling. The expression levels of MAPK pathway components can serve as biomarkers for cancer diagnosis, prognosis, and treatment response. For example, high levels of phosphorylated ERK (p-ERK) may indicate active MAPK signaling and poor prognosis in certain cancers. Numerous reports indicate that the MAPK pathway plays a major role in tumor progression and invasion, while inhibition of MAPK signaling reduces invasion. |
