| Hyperoside is a chemical compound and a quercetin galactoside. It is found in various plants and has antibacterial, antifungal and UV blocking properties. Hyperoside is an active ingredient in plants, such as Hypericum monogynum in Hypericaceae, Crataegus pinnatifida in Rosaceae and Polygonum aviculare in Polygonaceae. Hyperoside is a natural flavonol glycoside in various plants, such as Crataegus pinnatifida Bge, Forsythia suspensa, and Cuscuta chinensis Lam. **-Note NRF2 up in normal cells and down in cancer cells** -not currently available as supplement, but it is in Hawthorn Extract. (Natural factors lists it as hyperoside equilvalents 6.6mg/300mg) Hyperoside — also known as hyperin and quercetin-3-O-β-D-galactoside, is a naturally occurring flavonol glycoside consisting of quercetin conjugated at the 3-position to β-D-galactose. It is found in numerous medicinal and dietary plants including species of Hypericum, Crataegus, Polygonum, and Rhododendron. It is classified as a plant-derived flavonoid/polyphenolic small molecule. Hyperoside has antioxidant and cytoprotective activity in many normal-cell models but can produce cancer-selective stress responses, apoptosis, autophagy, and ferroptosis depending on tumor type and concentration. Its aglycone is quercetin. Primary mechanisms (ranked):
Bioavailability / PK relevance: Oral bioavailability of intact hyperoside appears poor. Rat studies found very low systemic exposure after intragastric administration, with substantially greater exposure after parenteral administration. Hyperoside is relatively resistant to gastrointestinal hydrolysis compared with isoquercitrin, which may limit absorption of its quercetin aglycone. Distribution studies indicate preferential accumulation in kidney relative to several other organs. Nanoparticle and liposomal formulations have therefore been investigated to improve delivery and tumor or mitochondrial accumulation. Long-term high-dose exposure warrants caution because renal toxicity has been reported preclinically. In-vitro vs systemic exposure relevance: Many anticancer experiments use approximately 10–100 µM hyperoside, while some autophagy studies have used 0.5–2 mM. These concentrations, particularly the millimolar experiments, are unlikely to represent achievable concentrations of unchanged hyperoside following conventional oral administration. Consequently, direct translation of many in-vitro anticancer effects to oral supplementation is weak without an exposure-enhancing formulation. Clinical evidence status: Preclinical. Anticancer activity has been demonstrated in multiple cancer-cell systems and several mouse xenograft or chemically induced tumor models, including lung, breast, pancreatic, skin, liver, colorectal, esophageal, and hematologic malignancy models. There is currently no established human anticancer efficacy, approved oncology indication, or convincing interventional clinical evidence for purified hyperoside. FDA substance registration identifies hyperoside chemically but does not constitute drug approval. Hyperoside Cancer-Relevant Mechanisms
Hyperoside and Alzheimer's disease: Hyperoside has significant preclinical neuroprotective evidence in Alzheimer's disease models. Long-term administration in APP/PS1 transgenic mice improved spatial learning and memory and reduced amyloid plaque deposition, tau phosphorylation, activated microglia and astrocytes, neuroinflammation, and oxidative stress. Mechanistic evidence implicates suppression of BACE1 and GSK-3β, protection of the blood-brain barrier, inhibition of mitochondrial and caspase-dependent apoptosis, and broader antioxidant/anti-inflammatory effects. Evidence remains preclinical; clinical efficacy in human Alzheimer's disease has not been established. Hyperoside Alzheimer's-Relevant Mechanisms

| P70S6K, or p70 S6 kinase, is a protein kinase that plays a significant role in the signaling pathways related to cell growth, proliferation, and survival. It is part of the mTOR (mechanistic target of rapamycin) signaling pathway, which is crucial for regulating cellular metabolism and growth in response to nutrients, growth factors, and stress signals. Expression Direction: In many cancers, p70S6K is frequently found to be overexpressed or hyperactivated. Increased phosphorylation (activation) of p70S6K is often detected, correlating with enhanced mTOR signaling. Elevated levels or hyperactivation of p70S6K in tumor tissues are generally associated with: More aggressive tumor behavior and higher proliferative indices. A poorer prognosis in several cancer types. • In cancers such as breast, lung, and gastrointestinal cancers, high p70S6K activity may correlate with advanced disease and decreased overall survival. |
