Biological Activity
| Targets | Endogenous Metabolite |
| ln Vitro | Deoxyuridine (dU) increases chromosome breakage at folic acid (FA)-sensitive common fragile sites (mostly 3p14 and 16q23) in human lymphocytes. This dU-related increase can be suppressed by thymidine or FA. These results suggest that the mechanism of fragile site expression in low FA medium involves misincorporation of dU into DNA[1]. |
| Enzyme Assay | A new photoisomeric nucleoside dUAz bearing an azobenzene group at the C5-position of 2'-deoxyuridine was designed and synthesized. Photoisomerization of dUAz in oligodeoxynucleotides can be achieved rapidly and selectively with 365 nm (forward) and 450 nm (backward) irradiation. Thermal denaturation experiments revealed that dUAz stabilized the duplex in the cis-form and destabilized it in the trans-form with mismatch discrimination ability comparable to thymidine. These results indicate that dUAz could be a powerful material for reversibly manipulating nucleic acid hybridization with spatiotemporal control[2]. |

| Additional Infomation |
2'-deoxyuridine is a pyrimidine 2'-deoxyribonucleoside having uracil as the nucleobase. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is functionally related to a uracil. Deoxyuridine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). 2'-Deoxyuridine has been reported in Homo sapiens, Biemna ehrenbergi, and other organisms with data available. Deoxyuridine is a nucleoside consisting of uracil and deoxyribose, which can act as an intermediate in thymidine synthesis. Deoxyuridine (dU) is used to indirectly determine if there are sufficient levels of folate and cobalamin in cell or tissue samples. 2'-Deoxyuridine. An antimetabolite that is converted to deoxyuridine triphosphate during DNA synthesis. Laboratory suppression of deoxyuridine is used to diagnose megaloblastic anemias due to vitamin B12 and folate deficiencies. |

Solubility in Formulation 1: ≥ 2.08 mg/mL (9.11 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (9.11 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.08 mg/mL (9.11 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 100 mg/mL (438.21 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.  (Please use freshly prepared in vivo formulations for optimal results.) |
