HYP, Hyperoside: Click to Expand ⟱
Features:
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.

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):

  1. Apoptosis induction through mitochondrial dysfunction, Bax/Bcl-2 modulation, cytochrome-c release, and caspase-9/caspase-3 activation.
  2. PI3K/AKT/mTOR suppression with autophagy induction; ATG13-mediated autophagy has recently been identified as an important mechanism in NSCLC.
  3. NF-κB pathway inhibition, reducing prosurvival and inflammatory signaling and promoting apoptotic susceptibility.
  4. Redox modulation with strong context dependence: hyperoside can suppress excessive ROS in breast-cancer and normal-cell models, while in other tumor contexts oxidative stress contributes to cytotoxicity.
  5. NRF2/SLC7A11/GPX4 suppression and ferroptosis induction in chronic myeloid leukemia; this contrasts with NRF2 activation and antioxidant cytoprotection in many normal-cell models.
  6. MAPK modulation including p38/JNK-mediated mitochondrial apoptosis and context-dependent ERK regulation.
  7. Cell-cycle arrest through p53/p21 and related regulatory pathways.
  8. Suppression of tumor-cell migration, invasion, EMT, and inflammatory signaling.
  9. Radiosensitization through suppression of STAT3/AKT/ERK signaling demonstrated preclinically in esophageal carcinoma.

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.

Direct NRF2 targeting has been reported in chronic myeloid leukemia, whereas normal cells commonly show NRF2 activation.
6 Redox regulation ↑ or ↓ ROS (context-dependent) ↓ excessive ROS; ↑ antioxidant defenses Context-dependent oxidative stress or antioxidant protection ROS direction is not uniform across cancer types. Breast-cancer studies report ↓ ROS, whereas some colorectal and ferroptotic models depend on increased oxidative stress.

10 Migration invasion and EMT ↓ migration; ↓ invasion; ↓ mesenchymal phenotype; ↑ E-cadherin Unclear ↓ metastatic phenotype Observed across several solid-tumor models including lung and esophageal carcinoma.
11 Radiosensitization ↑ radiation sensitivity; ↓ STAT3/AKT/ERK Insufficient evidence ↑ radiation-induced tumor control Demonstrated preclinically in esophageal carcinoma cells and mouse tumors; not clinically validated.
12 Clinical Translation Constraint Low oral exposure Potential renal accumulation with prolonged high-dose exposure Limits systemic translation Poor oral bioavailability and frequent use of high micromolar to millimolar experimental concentrations are major limitations. Targeted nanoparticles and liposomes may improve exposure.


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.

Also known as CP32.
Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death.
As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression.
Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy.
Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent.
On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer.
Procaspase-3 is a apoptotic marker protein.
Prognostic significance:
• High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers.
• Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers.
