Angelicin

Angelicin is a furanocoumarin compound found in Angelica and citrus plants that exhibits anti-inflammatory activity through NF-κB pathway suppression. This bioactive compound also demonstrates antiviral properties via protease inhibition mechanisms in laboratory studies.

Origin & History

Angelicin (isopsoralen) is an angular furocoumarin compound (C₁₁H₆O₃) naturally occurring in plants from the Apiaceae family including Pastinaca sativa (parsnip), Heracleum platytaenium, and Angelica archangelica roots. Extraction involves drying and powdering plant material followed by solvent extraction, with yields varying from 0.014% in Bituminaria morisiana seeds to 2.02% in Cicuta virosa dried whole plant.

Historical & Cultural Context

While angelicin-containing plants have been used traditionally - Pastinaca sativa as a sudorific/diuretic in North American remedies, Heracleum platytaenium for gastric issues in Turkish folk medicine, and Angelica archangelica in European herbalism - angelicin itself lacks direct traditional attribution. Psoralea corylifolia, another source, has been used in Ayurvedic and Chinese medicine primarily for its psoralen content.

Health Benefits

• Anti-inflammatory effects through suppression of NF-κB and MAPK signaling pathways (preliminary evidence from in vitro studies)
• Antiviral activity via virus protease inhibition (preliminary evidence from laboratory studies)
• Potential cytochrome P450 enzyme inhibition that may protect against toxic compounds (animal studies only)
• Possible apoptosis induction in abnormal cells (in vitro evidence only)
• Less phototoxic alternative to psoralen for potential skin applications (comparative laboratory studies)

How It Works

Angelicin suppresses inflammatory responses by inhibiting nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. The compound also inhibits viral proteases, preventing viral replication in infected cells. Additionally, angelicin may modulate cytochrome P450 enzyme activity, potentially affecting drug metabolism.

Scientific Research

No human clinical trials, randomized controlled trials, or meta-analyses have been conducted on angelicin as a standalone therapeutic agent. All existing evidence comes from preclinical in vitro and animal studies, with the primary review (PMC7176996) citing only laboratory research.

Clinical Summary

Current evidence for angelicin comes primarily from in vitro laboratory studies rather than human clinical trials. Cell culture studies have demonstrated anti-inflammatory effects through NF-κB pathway inhibition, though specific IC50 values and study durations vary across research. Antiviral activity has been observed in laboratory models against various viruses, but human efficacy data is lacking. More clinical research is needed to establish therapeutic dosages and confirm benefits in human subjects.

Nutritional Profile

Angelicin is a naturally occurring furanocoumarin (linear isomer of psoralen) and not a conventional nutritional ingredient — it contains no meaningful macronutrients, vitamins, or dietary minerals. It is a pure bioactive compound with a molecular weight of 186.16 g/mol and molecular formula C11H6O3. Found naturally in plants of the Apiaceae family (including Angelica archangelica, Angelica sinensis, Pimpinella anisum) typically at concentrations of 0.01–0.5% dry weight depending on plant part and species. As a furanocoumarin, it is lipophilic with moderate bioavailability; oral absorption is estimated to be moderate but subject to significant first-pass hepatic metabolism. It is not a source of protein, fat, carbohydrate, dietary fiber, or caloric energy in any meaningful quantity. Key bioactive identity: bicyclic aromatic lactone with a furan ring fused to a coumarin backbone. Trace amounts of angelicin from dietary plant sources (e.g., celery, parsley, angelica root) are consumed incidentally, estimated at microgram-level exposures in typical diets. Isolated/supplemental forms are used at milligram-range doses in research contexts. Bioavailability is influenced by CYP450 enzyme activity, which angelicin itself may partially inhibit, potentially creating auto-inhibitory pharmacokinetic effects. No established dietary reference intake or tolerable upper limit exists.

Preparation & Dosage

No clinically studied dosages exist due to absence of human trials. Plant extraction yields vary widely: 13.8 mg from 100.9g Bituminaria morisiana seeds, 60.5 mg from 3kg Cicuta virosa. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Safety & Interactions

Angelicin belongs to the furanocoumarin family, which can cause photosensitivity reactions when combined with UV light exposure. The compound may inhibit cytochrome P450 enzymes, potentially altering the metabolism of medications processed by these pathways. Pregnant and breastfeeding women should avoid angelicin due to insufficient safety data. Individuals taking prescription medications should consult healthcare providers before use due to potential drug interactions.
