Features:
Berberine is a chemical found in some plants like European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree turmeric. Berberine is a bitter-tasting and yellow-colored chemical.
Coptis (commonly referring to Coptidis Rhizoma, a traditional Chinese medicinal herb) contains bioactive alkaloids (most notably berberine and coptisine) that have been studied for their pharmacological effects—including their influence on reactive oxygen species (ROS) and related pathways.

– Berberine is known for its relatively low oral bioavailability, often cited at less than 1%. This low bioavailability is mainly due to poor intestinal absorption and active efflux by transport proteins such as P-glycoprotein.
– Despite the low bioavailability, berberine is still pharmacologically active, and its metabolites may also contribute to its overall effects.

• Effective Dosage in Studies
– Many clinical trials or preclinical studies use dosages in the range of 500 to 1500 mg per day, typically administered in divided doses.
– Therefore, to obtain a bioactive dose of berberine, supplementation in a standardized extract form is necessary.

-IC50 in cancer cell lines: Approximately 10–100 µM (commonly around 20–50 µM in many models)
-IC50 in normal cell lines: Generally higher (often above 100 µM), although this can vary with cell type
- In vivo studies: Dosing regimens in animal models generally range from about 50 to 200 mg/kg
- very effective AChE inhibitor (Alzheimers)
- Berberine may enhance the effects of blood-thinning medications like warfarin and aspirin.

AMPKα, AMP-activated protein kinase: Click to Expand ⟱
Source:
Type:
AMPK is a heterotrimeric protein complex consisting of three subunits: AMPKα, AMPKβ, and AMPKγ. AMPKα is expressed in two isoforms, AMPKα1 and AMPKα2, and these isoforms are encoded by the genes PRKAA1 and PRKAA2, respectively.
In many cancers, AMPKα acts as a tumor suppressor, and its downregulation is often associated with worse clinical outcomes.
