Features:
Flavonoid glycoside. Responsible for the bitterness of grapefruit.
Naringin is a flavonoid glycoside predominantly found in citrus fruits such as grapefruit and oranges. It is known for its antioxidant, anti-inflammatory, and potential anticancer properties.
It is hydrolyzed in vivo to naringenin, which exhibits antioxidant and anti-inflammatory activities and modulates signaling pathways (e.g., Nrf2 and NF-κB). In preclinical cancer models, naringin/naringenin is associated with cell-cycle arrest, apoptosis, and reduced invasion/metastasis, often linked to upstream modulation of survival pathways (PI3K/AKT) and stress MAPKs. Oral systemic exposure is limited due to metabolism and conjugation.
-Antioxidant Activity
-Induction of Apoptosis
-Cell Cycle Arrest (often G1 or G2/M)
-Anti-inflammatory Effects

-**a natural bioenhancer(effects vary) and reported to enhance the bioavailability of drugs by inhibiting cytochrome P450 (CYP3A4 especially grape fruit juice) and P-glycoprotein (P-gp). Naringin/naringenin can inhibit CYP3A4 and P-glycoprotein, contributing to grapefruit–drug interactions and potentially increasing exposure of certain medications.
-Usually paired with other bioflavonoids such as quercetin, hesperidin and rutin.

-Mainly obtained from grapefruit
-Including enhanced solubility, improved bioavailability and targeted delivery.
-Antioxidant
-Inhibition of CYP19(weak/modest). Naringin suppresses the PI3K/AKT signalling pathway
-Wnt/β-catenin, PI3K/Akt, NF-ĸB, and TGF-β pathways
-Up-regulation of adenosine monophosphate-activated protein kinase (AMPK), and inhibition of gluconeogenesis
-Antioxidant effects, by modulating reactive oxygen species (ROS) levels and increasing superoxide dismutase (SOD)
-Naringenin can reduce carcinogenesis through pleiotropic processes such as antioxidative, apoptotic-inducing ROS generation, and cell cycle arrest
-Revealed new mechanisms underlying the hypolipidemic effects of naringin and naringenin, including regulation of lipid digestion, reverse cholesterol transport, and low-density lipoprotein receptor expression
-Low bioavailability (approximately 8.8%) when administered orally. Bioavailability: citrus flavonoid glycosides are hydrolyzed in the gut; systemic plasma levels are often much lower than in vitro MICs.

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Nrf2/ARE antioxidant response Stress adaptation modulation (context-dependent) Nrf2 ↑; antioxidant enzymes ↑ R, G Endogenous antioxidant upshift Naringin and its aglycone naringenin are widely reported to activate Nrf2, elevate HO-1 and other antioxidant defenses, and reduce oxidative injury in many models.
2 NF-κB inflammatory signaling NF-κB ↓; pro-inflammatory cytokines ↓ (reported) Inflammation tone ↓ R, G Anti-inflammatory signaling Consistent evidence shows naringin/naringenin reduces pro-inflammatory signaling and cytokine expression in tumor and non-tumor contexts.
3 PI3K/AKT/mTOR survival axis PI3K/AKT ↓ (reported; model-dependent) R, G Growth/survival modulation Modulation of survival pathways is observed in various cancer‐cell studies, but effects vary by cell type and context.
4 Cell cycle control (Cyclins/CDKs) Cell-cycle arrest ↑ (G1/S or G2/M; reported) G Cytostasis Often reported as reduced proliferation and cell cycle arrest following upstream signaling changes.
5 Intrinsic apoptosis (mitochondrial/caspase linked) Apoptosis ↑; caspase activation ↑ (reported) G Execution of cell death Observed in many in vitro models, usually downstream of signaling modulation and stress pathways.
6 MAPK re-wiring (ERK / JNK / p38) MAPK modulation (context-dependent) P, R, G Stress/mitogenic signaling adjustment MAPK effects vary by assay and cell type; avoid fixed up/down arrows without a specific citation.
7 Invasion / metastasis programs (MMPs/EMT) MMPs ↓; migration/invasion ↓ (reported) G Anti-invasive phenotype Downstream phenotype changes reported in some models; linked to NF-κB/MAPK modulation.
8 Angiogenesis signaling (VEGF & related) Angiogenic outputs ↓ (reported) G Anti-angiogenic support Later phenotype outcomes; direction is often model-dependent.
9 Reactive oxygen species modulation Redox buffering; ROS direction variable P, R, G Redox modulation (context-dependent) Naringin is classically antioxidant; ROS changes in cancer models vary and are not reliably pro-oxidant under typical conditions.
10 Bioavailability / metabolism constraint Systemic exposure limited; rapid metabolism/conjugation Translation constraint Naringin’s glycoside form is hydrolyzed to naringenin; phase II conjugates circulate. Native systemic levels are often low compared with in vitro effective concentrations.

  • P: 0–30 min (rapid biochemical/signaling interactions)
  • R: 30 min–3 hr (acute signaling and transcription modulation)

Type:
Cyclooxygenase-2 (COX-2) is an enzyme that plays a critical role in the conversion of arachidonic acid to prostaglandins, which are lipid compounds involved in various physiological processes, including inflammation, pain, and fever. COX-2 is an inducible enzyme, meaning its expression is typically low in normal tissues but can be upregulated in response to inflammatory stimuli, growth factors, and certain oncogenic signals.
-Cyclooxygenase-2 (COX-2), the rate-limiting enzyme in prostaglandin biosynthesis, plays a key role in inflammation and circulatory homeostasis.
-COX-2 is an inducible enzyme that is upregulated in response to pro-inflammatory signals, including cytokines (e.g., IL-1β, TNF-α) and growth factors.

COX-2 is often overexpressed in various tumors, including colorectal, breast, lung, and prostate cancers.
The prostaglandins produced by COX-2, particularly prostaglandin E2 (PGE2), have several effects that can facilitate cancer progression:
Cell Proliferation: PGE2 can promote the proliferation of cancer cells by activating signaling pathways such as the PI3K/Akt and MAPK pathways.
Nonselective NSAIDs, such as aspirin and ibuprofen, inhibit both COX-1 and COX-2. Epidemiological studies have suggested that regular use of NSAIDs may reduce the risk of certain cancers, particularly colorectal cancer.
Drugs specifically targeting COX-2, such as celecoxib, have been developed.

COX-2 and xanthine oxidase are ROS-producing pro-oxidant enzymes that contribute to inflammation. Elevated COX‑2 levels, often found in inflammatory conditions or certain types of cancers, can contribute to increased production of ROS.
