Fangchinoline

Fangchinoline is a bisbenzylisoquinoline alkaloid extracted from Stephania tetrandra that demonstrates neuroprotective and antiproliferative properties. Research indicates it works primarily through modulation of oxidative stress pathways and cellular signaling cascades.

Origin & History

Fangchinoline is a bisbenzylisoquinoline alkaloid isolated from the roots of Stephania tetrandra (Hanfangji), a plant in the Menispermaceae family native to China. It is extracted using solvent methods such as chloroform or methanol, yielding a white to orange-green powder with the molecular formula C₃₇H₄₀N₂O₆.

Historical & Cultural Context

Fangchinoline is found in Stephania tetrandra, used in traditional Chinese medicine for over 1,000 years to treat edema, hypertension, inflammation, and pain. The root is traditionally prepared as decoctions or powders in formulas like Fangji Huangqi Tang for rheumatoid arthritis-like symptoms, as noted in historical texts like Shennong Bencao Jing.

Health Benefits

• May reduce neuronal damage from oxidative stress (preclinical evidence only - rat cerebellar neurons at 1-10 µM)
• Potential antiproliferative effects on cancer cells (in vitro studies on breast cancer cell lines only)
• Possible anti-inflammatory activity through cellular pathway modulation (animal models only)
• May inhibit acetylcholinesterase enzyme activity (mechanism studies only, no human data)
• Potential calcium channel modulation effects (preclinical mechanistic studies only)

How It Works

Fangchinoline exerts neuroprotective effects by reducing oxidative stress in neuronal cells, particularly at concentrations of 1-10 µM in rat cerebellar neurons. The compound demonstrates antiproliferative activity against breast cancer cell lines through cellular pathway modulation. Its anti-inflammatory properties appear to involve modulation of key inflammatory signaling cascades at the cellular level.

Scientific Research

No human clinical trials, randomized controlled trials, or meta-analyses have been conducted on fangchinoline. All available research is limited to preclinical in vitro and animal studies, such as its effects on rat cerebellar granule neurons at 1-10 µM concentrations and antiproliferative activity in breast cancer cell lines.

Clinical Summary

Current evidence for fangchinoline is limited to preclinical studies with no human clinical trials available. In vitro studies have shown neuroprotective effects on rat cerebellar neurons at 1-10 µM concentrations. Antiproliferative effects have been demonstrated specifically in breast cancer cell lines during laboratory studies. Animal studies suggest anti-inflammatory activity, but human efficacy and safety data remain unavailable.

Nutritional Profile

Fangchinoline is a bisbenzylisoquinoline alkaloid compound (molecular formula C₃₇H₄₀N₂O₆, molecular weight ~608.7 g/mol) isolated primarily from Stephania tetrandra (Han Fang Ji) root. It is not a nutritional ingredient and contains no meaningful macronutrients, micronutrients, vitamins, minerals, or dietary fiber. As a purified bioactive alkaloid, it is studied exclusively for pharmacological properties rather than nutritional value. Bioactive concentration in Stephania tetrandra root extract is typically in the range of 0.1–1.5% dry weight alongside its structural isomer tetrandrine. In experimental contexts, active concentrations range from 1–50 µM in cell-based studies. Bioavailability data in humans is absent; preclinical pharmacokinetic data suggests moderate lipophilicity (estimated logP ~3.5–4.5) which may facilitate membrane permeability, but first-pass metabolism and oral bioavailability have not been formally characterized in human studies. No recommended dietary intake, tolerable upper limit, or nutritional reference value exists for this compound. It is not present in conventional foods and is not considered a nutrient.

Preparation & Dosage

No clinically studied dosages exist for humans. Preclinical studies use 1-10 µM concentrations in cell cultures. Commercial forms are available as 95-99% pure powder, but no safe human dosage has been established. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Tetrandrine, Green Tea Extract, Quercetin, Resveratrol, Curcumin

Safety & Interactions

Safety data for fangchinoline in humans is extremely limited due to lack of clinical trials. Potential drug interactions with medications metabolized through similar pathways remain unknown and unstudied. Pregnancy and breastfeeding safety has not been established through research. Individuals should consult healthcare providers before using fangchinoline-containing supplements due to insufficient safety data.
