Glucose metabolism; glycolysis; hexokinase; HSV-1; Antimetabolites; Antiviral Agents； 2 - DG targets hexokinase. It can be phosphorylated by hexokinase to form 2 - DG - 6 - phosphate, which accumulates in cells and inhibits hexokinase activity, thus blocking glycolysis. It also competitively inhibits phosphoglucose isomerase as 2 - DG - 6 - phosphate can compete with fructose - 6 - phosphate for phosphoglucose isomerase.

In MCF-7 cells, 2-Deoxy-D-glucose (2-DG), 4, 8, or 16 mM, dramatically decreased ATP levels in a dose- and time-dependent manner that was comparable to the effect of 2-DG on cell growth. exposure to 4, 8 or 16 mM 2-Deoxy-D-glucose 1, 3 or for 5 days in a way that depends on the dose and the amount of time [1]. When 2-DG is administered, pentose phosphate pathway (PPP) responders are upregulated, and 6-phosphate endpoint dehydrogenase produces more NADPH. The 2-DG reduced form of glutathione is elevated in NB4 cells due to an increase in NADPH and an upregulation of glutathione synthetase expression [3].

In mammary tumor cells, 2 - DG inhibits cell growth in a dose - and time - dependent manner. It reduces cell viability, blocks cell cycle progression at the G1/S phase, and induces apoptosis. The mechanism may be related to the inhibition of glycolysis, which leads to a decrease in ATP production and an increase in reactive oxygen species (ROS) levels [1]
In leukemia cells, 2 - DG disrupts the metabolic balance, leading to a decrease in glucose consumption and lactate production. It also causes a decrease in intracellular ATP levels and an increase in ROS, which may lead to cell death [3]

2-Deoxy-D-glucose (0.03%, w/w) postponed the possible beginning of breast cancer and led to a statistically significant 7% reduction in final body weight [1]. 2. During extraction, 2-Deoxy-D-glucose (3 mmol/kg, iv) is lowered in a dose-dependent manner [2].
Note: Despite the numerous preclinical and clinical studies, the use of 2-DG in cancer and viral treatment has been limited. Its rapid metabolism and short half-life (according to Hansen et al., after treatment with infusion of 50 mg/kg2-DG, its plasma half-life was only 48 min), make 2-DG a relatively poor drug candidate. Moreover, 2-DG must be given at relatively high concentrations (≥5 mmol/L) to compete with blood glucose. According to Stein et al., the dose of 45 mg/kg received orally on days 1–14 was defined as safe because patients did not experience any dose-limiting toxicities. Notably, at the dose of 60 mg/kg, two patients experienced dose-limiting toxicity of grade 3–asymptomatic QTc prolongation. According to former studies published by Burckhardt et al. and Stalder et al., among patients exposed to 2-DG, non-specific T wave flattening and QT prolongation, without any event of severe arrhythmia, developed.[4]

In lipopolysaccharide/d - galactosamine (LPS/D - Gal) - induced lethal liver injury mouse models, 2 - DG treatment suppresses the elevation of plasma aminotransferases, alleviates histopathological abnormalities, and improves the survival rate of mice. It also suppresses the production of pro - apoptotic cytokine TNF - α, the phosphorylation of JNK, the activation of the caspase cascade, and the number of TUNEL - positive apoptotic hepatocytes [4]

ATP assay. The effect of 2-DG on ATP level in the cells was determined using an ENLITEN ATP assay kit (Promega Corporation, Kadison, WI), the bioluminescence was detected using a TD 20/20 luminometer (Turner Biosystem, Sunnyvale, CA), and the amount of ATP per well was standardized by the cell number estimated by crystal violet method described above.[1]

Using MCF-7 human breast cancer cells to investigate the signaling pathways perturbed by disruption of glucose metabolism, 2-DG reduced cell growth and intracellular ATP in a dose- and time-dependent manner (P < 0.01). Treatment with 2-DG increased levels of phosphorylated AMP-activated protein kinase and Sirt-1 and reduced phosphorylated Akt (P < 0.05). These studies support the hypothesis that DER inhibits carcinogenesis, in part, by limiting glucose availability and that energy metabolism is a target for the development of ERMA for chemoprevention.[1]

For mammary tumor cells, different concentrations of 2 - DG are added to the cell culture medium, and the cells are cultured for different time periods (such as 24h, 48h, 72h). Then, the cell viability is detected by the MTT method, and the cell cycle is analyzed by flow cytometry using propidium iodide staining. Apoptosis is detected by Annexin V - FITC/PI double - staining and flow cytometry. Intracellular ATP levels are measured by a luciferase - based assay, and ROS levels are detected by fluorescent probes [1]
For leukemia cells, they are cultured in the presence of 2 - DG, and the glucose consumption and lactate production in the culture medium are measured at regular intervals. Intracellular ATP levels are detected by a luciferase - based assay, and ROS levels are detected by fluorescent probes [3]

For the carcinogenesis study, ninety 21-day-old female Sprague-Dawley rats were injected i.p. with 50 mg of 1-methyl-1-nitrosourea per kilogram of body weight. Following injection, animals were ad libitum fed AIN-93G diet containing 0.00%, 0.02%, or 0.03% (w/w) 2-DG for 5 weeks. 2-DG decreased the incidence and multiplicity of mammary carcinomas and prolonged cancer latency (P < 0.05). The 0.02% dose of 2-DG had no effect on circulating levels of glucose, insulin, insulin-like growth factor-I, IGF binding protein-3, leptin, or body weight gain. [1]

In the LPS/D - Gal - induced liver injury mouse model, 2 - DG is dissolved in normal saline. Mice are intraperitoneally injected with 2 - DG at a dose of 200 mg/kg once a day for 7 consecutive days. The control group is injected with the same volume of normal saline. Then, the plasma aminotransferase levels are measured, and the liver tissue is used for histopathological examination and TUNEL staining to detect apoptosis [4]

2-deoxy-D-glucose has been reported in Streptomyces nigra with data available.
2-Deoxy-D-glucose is a non-metabolizable glucose analog in which the hydroxyl group at position 2 of glucose is replaced by hydrogen, with potential glycolysis inhibiting and antineoplastic activities. Although the exact mechanism of action has yet to be fully elucidated, upon administration of 2-deoxy-D-glucose (2-DG), this agent competes with glucose for uptake by proliferating cells, such as tumor cells. 2-DG inhibits the first step of glycolysis and therefore prevents cellular energy production, which may result in decreased tumor cell proliferation.
2-deoxy-D-glucose is a metabolite found in or produced by Saccharomyces cerevisiae.
2-Deoxy-D-arabino-hexose. An antimetabolite of glucose with antiviral activity.

2 - DG is a glucose analog, which is the first - proposed calorie restriction mimetic. By blocking glycolysis, it can mimic the metabolic, hormonal, and physiological effects of calorie restriction, and has a beneficial effect on chronic pathological processes such as cancer, Alzheimer 's disease, and Parkinson 's disease. It can also protect against acute ischemia injury in rats. Its role in inhibiting glycolysis is of great significance for the study of tumor cell metabolism and the development of anti - cancer strategies [4]
