| 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.

| Glutathione (GSH) is a thiol antioxidant that scavenges reactive oxygen species (ROS), resulting in the formation of oxidized glutathione (GSSG). Decreased amounts of GSH and a decreased GSH/GSSG ratio in tissues are biomarkers of oxidative stress. Glutathione is a powerful antioxidant found in every cell of the body, composed of three amino acids: cysteine, glutamine, and glycine. It plays a crucial role in protecting cells from oxidative stress, detoxifying harmful substances, and supporting the immune system. cancer cells can have elevated levels of glutathione, which may help them survive in the oxidative environment created by the immune response and chemotherapy. This can make cancer cells more resistant to treatment. While glutathione can be obtained from certain foods (like fruits, vegetables, and meats), its absorption from supplements is debated. Some people take N-acetylcysteine (NAC) or other precursors to boost glutathione levels, but the effects on cancer prevention or treatment are still being studied. Depleting glutathione (GSH) to raise reactive oxygen species (ROS) is a strategy that has been explored in cancer research and therapy. Many cancer cells have altered redox states and may rely on GSH to survive. Increasing ROS levels can induce stress in these cells, potentially leading to cell death. Certain drugs and compounds can deplete GSH levels. For example, agents like buthionine sulfoximine (BSO) inhibit the synthesis of GSH, leading to its depletion. Cancer cells tend to exhibit higher levels of intracellular GSH, possibly as an adaptive response to a higher metabolism and thus higher steady-state levels of reactive oxygen species (ROS). "...intracellular glutathione (GSH) exhibits an astounding antioxidant activity in scavenging reactive oxygen species (ROS)..." "Cancer cells have a high level of GSH compared to normal cells." "...cancer cells are affluent with high antioxidant levels, especially with GSH, whose appearance at an elevated concentration of ∼10 mM (10 times less in normal cells) detoxifies the cancer cells." "Therefore, GSH depletion can be assumed to be the key strategy to amplify the oxidative stress in cancer cells, enhancing the destruction of cancer cells by fruitful cancer therapy." The loss of GSH is broadly known to be directly related to the apoptosis progression. |
