Matricine

Matricine is a sesquiterpene lactone found primarily in chamomile (Matricaria chamomilla) that partially converts to chamazulene during steam distillation. Its primary mechanisms involve inhibition of pro-inflammatory enzymes such as COX-2 and NF-κB signaling, alongside induction of apoptosis in cancer cell lines.

Origin & History

Matricine is a proazulene sesquiterpene found in the flower heads of chamomile (Matricaria recutita), native to Europe. It is typically extracted through steam distillation from dried chamomile flowers.

Historical & Cultural Context

Matricine is found in chamomile, which has a long history in European traditional medicine for anti-inflammatory and anxiolytic purposes. While chamomile is well-studied, matricine's specific historical use is not documented.

Health Benefits

• Inhibits proliferation of gemcitabine-resistant pancreatic cancer cells by inducing apoptosis and blocking migration/invasion pathways, based on in vitro studies.
• Reduces tumor incidence and inflammatory cytokines in a mouse model of lung cancer, as shown in preclinical in vivo research.
• Elevates antioxidant levels while reducing oxidative stress markers in animal studies.
• Demonstrates anti-inflammatory activity, confirmed through in vitro research.
• Modulates apoptosis-related proteins and improves immune response in preclinical models.

How It Works

Matricine suppresses NF-κB transcriptional activity, thereby downregulating pro-inflammatory cytokines including TNF-α and IL-6 while inhibiting COX-2-mediated prostaglandin synthesis. In cancer cell models, it induces mitochondria-dependent apoptosis by modulating Bcl-2/Bax ratios and activating caspase-3 and caspase-9 cascades. Additionally, matricine disrupts epithelial-mesenchymal transition (EMT) by inhibiting matrix metalloproteinases MMP-2 and MMP-9, reducing cellular migration and invasion.

Scientific Research

No human clinical trials or meta-analyses on matricine were identified. Existing evidence is limited to preclinical in vitro and in vivo animal studies, with specific study details provided in the research dossier.

Clinical Summary

Preclinical in vitro studies demonstrate that matricine inhibits proliferation of gemcitabine-resistant pancreatic cancer cell lines by triggering intrinsic apoptotic pathways, though specific IC50 values vary across studies. Mouse model research shows reduced lung tumor incidence alongside decreased circulating inflammatory cytokines following matricine administration, representing promising but early-stage in vivo evidence. No large-scale randomized controlled human clinical trials on isolated matricine have been published as of 2024, meaning the evidence base is entirely preclinical. The overall evidence strength is low-to-moderate and insufficient to support definitive therapeutic claims in humans without further clinical investigation.

Nutritional Profile

Matricine is a pure bioactive sesquiterpene lactone compound (molecular formula C17H20O5, molecular weight 308.33 g/mol), not a whole food or nutritional ingredient, and therefore carries no meaningful macronutrient, micronutrient, fiber, or protein content. As an isolated phytochemical, it does not contribute calories, carbohydrates, fats, or proteins in relevant quantities. Bioactive compound identity: Matricine is a proazulene-type sesquiterpene lactone, classified as a guaianolide skeleton compound. It is the biosynthetic precursor to chamazulene, converting to the blue-pigmented chamazulene (C14H16) upon steam distillation or heating, which is responsible for the characteristic blue color of chamomile essential oil. Concentration in source plants: Found primarily in Matricaria chamomilla (German chamomile) flower heads at approximately 0.1–0.5% of dry weight, depending on chemotype, growing conditions, and harvest timing. Also detected in Tanacetum parthenium (feverfew) and related Asteraceae species at lower concentrations. Co-occurring bioactives in source material include alpha-bisabolol (up to 50% of essential oil fraction), apigenin-7-glucoside, luteolin, and quercetin glycosides, though these are distinct from matricine itself. Solubility and bioavailability: Matricine is lipophilic with limited aqueous solubility, suggesting absorption may be enhanced with lipid co-administration. It is heat-labile, converting irreversibly to chamazulene above approximately 100°C. Oral bioavailability data in humans is not formally established; preclinical studies suggest cellular uptake via passive diffusion consistent with its lipophilic sesquiterpene structure. No established dietary reference intake or recommended daily allowance exists for this compound.

Preparation & Dosage

No clinically studied dosages in humans are available. Preclinical mouse studies used an oral dose of 100 mg/kg body weight daily. Consult a healthcare provider before starting any new supplement.

Safety & Interactions

Matricine is a sesquiterpene lactone and shares structural features with known contact allergens; individuals with documented allergies to Asteraceae/Compositae family plants (ragweed, chrysanthemums, daisies) face elevated risk of hypersensitivity reactions including contact dermatitis. No well-characterized drug interaction data specific to isolated matricine exists, but theoretical interactions with anticoagulants and NSAIDs are plausible given its COX-2 inhibitory activity. Pregnancy and lactation safety has not been established in controlled studies, and use should be avoided in these populations until more data are available. High-dose supplementation with concentrated sesquiterpene lactone extracts should be approached cautiously in individuals on immunosuppressive or chemotherapy regimens without physician oversight.
