| 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.

| The cytochrome P450 (CYP) family includes many isoenzymes that play key roles in metabolizing endogenous substances (like hormones) and xenobiotics (including drugs and toxins). Changes in the expression of these enzymes in various cancers can affect carcinogen activation, drug metabolism, and overall tumor biology, influencing both cancer risk and prognosis. CYP1B1 – Frequently overexpressed in several cancers including breast, ovarian, prostate, and colorectal cancers. – Its expression is often low in normal tissues, making it a potential target for selective cancer therapies. 2. CYP3A4 and CYP3A5 These enzymes are highly expressed in the liver, but their expression is also observed in extrahepatic tissues. – In cancer, CYP3A enzymes can be variably expressed; for instance, CYP3A4 may be upregulated in some liver cancers but downregulated in others. 3. CYP2E1 – CYP2E1 is expressed in the liver and extrahepatic tissues. – Elevated CYP2E1 activity can lead to increased production of reactive oxygen species (ROS), contributing to DNA damage and cancer progression. 4. CYP19A1 (Aromatase) – Aromatase converts androgens to estrogens and is expressed in adipose tissue as well as in certain tumors such as breast cancer. – Its local expression in breast tumors can increase estrogen levels, promoting hormone-dependent tumor growth. 5. CYP2C Family (e.g., CYP2C8, CYP2C9, CYP2C19) – These enzymes are involved in metabolizing various drugs and are expressed in the liver and intestines. – Their expression levels can be altered in different tumor types, potentially affecting drug metabolism. CYP450 enzymes are a large family with diverse roles in cancer biology. • Their expression in cancers (e.g., CYP1B1, CYP3A4/5, CYP2E1, CYP19A1) has been linked to both the development and progression of tumors, as well as influencing responses to therapy. |
