Arctigenin

Phenolics Lignans Natural (plant-derived)

Arctigenin is a dibenzylbutyrolactone lignan and the aglycone of arctiin — the most-studied bioactive of burdock seed. Best known preclinically as the first "antiausterity" agent (selectively killing tumor cells under glucose deprivation), with anti-inflammatory, antiviral and metabolic activity; the only human data are early-phase trials of an arctigenin-rich burdock-seed extract, not the pure compound.

Arctigenin at a Glance

Arctigenin is a dibenzylbutyrolactone lignan and the most-studied bioactive of burdock seed — the aglycone released from arctiin by gut bacteria.

Its distinction is being the first described “antiausterity” agent: a compound that selectively kills tumour cells under glucose deprivation, exploiting the fact that cancer cells in poorly vascularised tumour cores cannot tolerate starvation the way normal cells can. That is a genuinely different anticancer strategy from cytotoxicity.

It also carries antiviral and anti-inflammatory preclinical work.

What It's Used For

Arctigenin is a dibenzylbutyrolactone lignan — the aglycone of arctiin (its glucoside prodrug) — and the most-studied bioactive of burdock (Arctium lappa) seed, where it concentrates far more than in the root. Its signature is a mechanism: arctigenin was identified as the first “antiausterity” agent, preferentially killing tumor cells under glucose starvation while sparing glucose-fed cells 1Reference 1Awale S et al. · 2006Identification of arctigenin as an antitumour agent that has the ability to eliminate the tolerance of cancer cells to nutrient starvationView study →.

Two caveats frame everything. First, the only human data come from an arctigenin-rich burdock-seed extract (GBS-01), a multi-component preparation — never from the isolated compound 4Reference 4Ikeda M et al. · 2016Phase-I trial of GBS-01 for advanced pancreatic cancer refractory to gemcitabineView study →.

Second, its poor oral bioavailability (extensive first-pass glucuronidation) is the central translational limiter 16Reference 16Gao Q et al. · 2014AnimalExtensive intestinal first-pass elimination of arctigenin in ratsView study →.

A distinctive anticancer mechanism:glucose-deprivation-selective cytotoxicity via AMPK/mTOR (“antiausterity”), plus STAT3 and HER2 signaling in breast-cancer models 1,2,3Reference 1Awale S et al. · 2006Identification of arctigenin as an antitumour agent that has the ability to eliminate the tolerance of cancer cells to nutrient starvationView study →Reference 2Shi H et al. · 2020Arctigenin attenuates breast cancer progression through the GM-CSF/TSLP/STAT3/β-catenin axisView study →Reference 3Lee MG et al. · 2021Arctigenin-mediated cell death of SK-BR-3 cells via HER2 inhibition and autophagy-linked apoptosisView study → — all preclinical.
Human data are extract-based:an early-phase trial of GBS-01 (arctigenin-rich burdock-seed extract) in gemcitabine-refractory pancreatic cancer showed tolerability and occasional responses, but efficacy cannot be attributed to arctigenin alone 4,5Reference 4Ikeda M et al. · 2016Phase-I trial of GBS-01 for advanced pancreatic cancer refractory to gemcitabineView study →Reference 5Fujioka R et al. · 2018Clinical trialChange in plasma lactate concentration during arctigenin administration in a phase-I clinical trialView study →.
The honest headline:consistent anti-inflammatory, antiviral and metabolic activity in rodents, undercut by poor oral bioavailability 8,16Reference 8Wu D et al. · 2022Arctigenin: pharmacology, total synthesis, and progress in structure modificationView study →Reference 16Gao Q et al. · 2014AnimalExtensive intestinal first-pass elimination of arctigenin in ratsView study → and no isolated-compound human trial.
Evidence by IndicationStrength of support · Beta

Support is an experimental score — weighted by study type (human > animal > in vitro) and volume. A beta, not a validated metric. Human data are limited to an extract program, so isolate scores stay low. Each application links to its write-up.

Pharmacokinetics

Poor oral bioavailability is the dominant story. Arctigenin undergoes extensive intestinal first-pass glucuronidation (UGT-mediated), so the parent is largely conjugated before systemic exposure and plasma parent levels are low and short-lived 16,8Reference 16Gao Q et al. · 2014AnimalExtensive intestinal first-pass elimination of arctigenin in ratsView study →Reference 8Wu D et al. · 2022Arctigenin: pharmacology, total synthesis, and progress in structure modificationView study →. The implication runs through every application above: efficacy likely needs enriched extracts (the GBS-01 rationale), high oral doses, or delivery strategies, and the impressive rodent potencies are not demonstrably reachable from ordinary intake — which comes indirectly from burdock seed (Niu Bang Zi), where arctigenin is concentrated far above the root 17Reference 17Wang G et al. · 2023ReviewThe therapeutic potential of arctigenin against multiple diseases: a mechanistic reviewView study →.

Clinical trials

The only human data are the GBS-01 extract program — a phase-I dose-finding trial in advanced pancreatic cancer refractory to gemcitabine (tolerability, occasional responses) 4Reference 4Ikeda M et al. · 2016Phase-I trial of GBS-01 for advanced pancreatic cancer refractory to gemcitabineView study → and a companion pharmacodynamic study 5Reference 5Fujioka R et al. · 2018Clinical trialChange in plasma lactate concentration during arctigenin administration in a phase-I clinical trialView study →. There are no trials of isolated or pure arctigenin for any indication; every human data point traces to the arctigenin-rich extract.

Toxicity & Safety

Arctigenin looks clean preclinically, but the entire human safety record is one phase-I oncology trial of an extract — its interaction cautions are mechanism-based rather than observed.

Safety at a Glance
Low / no toxicityDrug interactions
  • Low toxicity across rodent efficacy studies. No signal of overt organ toxicity at effective doses.
  • Avoid in pregnancy and breastfeeding. No reproductive data, plus phytoestrogen-class and immunomodulatory activity.
  • Human safety data come from a cancer population only. “Generally low preclinically” is not proven safe.
  • Theoretical UGT interactions. Heavily glucuronidated, so it may interact with UGT substrates or inhibitors.
  • Immunosuppressant and antidiabetic overlap. NF-κB suppression and rodent insulin-sensitizing effects imply additive risk.
Full Safety & Interactions Detail

Arctigenin shows low toxicity across the rodent efficacy studies, with no signal of overt organ toxicity at effective doses 6Reference 6Zhao F et al. · 2009In vitroAnti-inflammatory effects of arctigenin, a lignan from Arctium lappa, in vitroView study →, and the GBS-01 phase-I trial established a tolerable dose in cancer patients 4Reference 4Ikeda M et al. · 2016Phase-I trial of GBS-01 for advanced pancreatic cancer refractory to gemcitabineView study → — though a measurable rise in plasma lactate during dosing 5Reference 5Fujioka R et al. · 2018Clinical trialChange in plasma lactate concentration during arctigenin administration in a phase-I clinical trialView study → is a metabolic effect worth noting rather than an established adverse event. Its interaction profile is theoretical and mechanism-based: as a heavily UGT-glucuronidated molecule it may interact with UGT substrates or inhibitors 16Reference 16Gao Q et al. · 2014AnimalExtensive intestinal first-pass elimination of arctigenin in ratsView study →, its NF-κB-suppressing/immunomodulatory action warrants caution alongside immunosuppressants 6Reference 6Zhao F et al. · 2009In vitroAnti-inflammatory effects of arctigenin, a lignan from Arctium lappa, in vitroView study →, and its rodent insulin-sensitizing effect implies additive risk with antidiabetic drugs 14Reference 14Zhou Y et al. · 2023Arctigenin mitigates insulin resistance via modulating the IRS2/GLUT4 pathwayView study →.

Human safety data are confined to a cancer population — “generally low preclinically” is not the same as proven safe.

Dosage

There is no established human dose for isolated arctigenin, and nothing here is a recommendation. The only human dosing reference is the GBS-01 extract, titrated under oncology supervision in the phase-I pancreatic-cancer study — an extract standardized to arctigenin content, not a pure-compound dose 4Reference 4Ikeda M et al. · 2016Phase-I trial of GBS-01 for advanced pancreatic cancer refractory to gemcitabineView study →. Preclinical doses are rodent mg/kg figures that do not convert to safe human intake, and any real-world intake comes indirectly from burdock-seed preparations.
