Features:
Myricetin (MYR; 3,3′,4′,5,5′,7-hexahydroxyflavone) is a dietary flavonol polyphenol abundant in berries, tea, red wine, and some medicinal plants. Its dominant biology is redox-active modulation with context-dependent pro-oxidant capacity, ranking conceptually as:
(1) ROS modulation (scavenging at low dose; pro-oxidant at higher dose or with metal redox cycling),
(2) PI3K/Akt/mTOR and MAPK pathway inhibition,
(3) NF-κB suppression and inflammatory signaling control, and
(4) mitochondrial apoptosis induction (caspase activation, ΔΨm disruption).
Bioavailability is limited by low aqueous solubility and rapid conjugation (glucuronidation/sulfation); reported human plasma levels after dietary exposure are typically sub-micromolar (<1 µM), while many in-vitro cancer studies use 10–100 µM, often exceeding realistic systemic exposure. Clinical evidence remains preclinical-dominant; no robust RCT-grade anticancer efficacy established. Redox duality implies potential chemo-sensitization in oxidative tumors but also theoretical protection of normal tissue.

Myricetin (MYR) — Cancer-Relevant Pathway Effects

Rank Pathway / Axis Cancer Cells (↑/↓/↔ + qualifiers) Normal Cells (↑/↓/↔ + qualifiers) TSF Primary Effect Notes / Interpretation
1 ROS Modulation ↑ ROS (high conc., pro-oxidant); ↓ ROS (low conc.) ↓ ROS (protective; dose-dependent) P–R Redox stress induction or buffering Metal-chelating flavonol; can shift to pro-oxidant under tumor oxidative stress, enabling apoptosis.
2 PI3K/Akt/mTOR ↓ Akt phosphorylation (model-dependent) ↔ / mild inhibition R–G Anti-proliferative signaling Common in breast, colon, and prostate cell models; often ≥10 µM required.
3 MAPK (ERK/JNK/p38) ↓ ERK; ↑ JNK/p38 (stress-activated; context) ↔ / adaptive stress response R Pro-apoptotic signaling shift Promotes apoptotic cascades via stress kinase activation.
4 NF-κB ↓ NF-κB activation ↓ NF-κB (anti-inflammatory) R–G Anti-inflammatory modulation May reduce tumor-promoting inflammation.
5 Mitochondrial Apoptosis (Caspase / ΔΨm) ↑ Bax; ↓ Bcl-2; ↑ caspase-3 ↔ / protective at low dose R–G Intrinsic apoptosis activation Frequently observed in leukemia and solid tumor models at supra-physiologic doses.
6 NRF2 Axis ↔ / mild ↑ (context-dependent) ↑ NRF2 (cytoprotection) R–G Adaptive antioxidant response Less potent NRF2 activator than electrophilic isothiocyanates.
7 Ca²⁺ Signaling ↑ intracellular Ca²⁺ (mitochondrial stress; model-dependent) ↔ R Apoptosis facilitation Reported in some hepatoma and leukemia models.
8 Ferroptosis ↔ / potentially ↓ (iron-chelating) ↔ — Lipid peroxidation modulation Chelation may counter ferroptosis unless combined with pro-oxidant triggers.
9 Clinical Translation Constraint Low oral bioavailability; plasma <1 µM; most anticancer studies use 10–100 µM — PK limitation Conjugation and rapid metabolism limit systemic tumor exposure.

Type:
ADAM10 (A Disintegrin And Metalloproteinase Domain-Containing Protein 10) plays a critical protective role in Alzheimer’s disease (AD) due to its function as an α-secretase, an enzyme involved in the non-amyloidogenic processing of the amyloid precursor protein (APP).
-By preventing Aβ accumulation, ADAM10 indirectly reduces amyloid plaques.br> -Downregulation of ADAM10 is observed in AD brains.
-ADAM10 levels are especially diminished in individuals with an APOE4 genotype
