| Targets |
2',3'-cUMP sodium acts as a competitive inhibitor of ribonuclease A (RNase A). By binding to the active site of the enzyme, it prevents the enzyme from binding to and cleaving RNA. Specifically, it is a transition-state analog, meaning it mimics the geometry and charge of the RNA molecule as it is being hydrolyzed, leading to tight binding to the enzyme's active site. It is also a competitive inhibitor of di-p-nitrophenyl phosphate hydrolysis.
|
|---|---|
| ln Vitro |
In vitro, 2',3'-cUMP is used in enzyme kinetics assays to inhibit the activity of RNase A. The inhibition constant (Ki) can be determined by measuring the enzyme's activity in the presence of varying concentrations of the inhibitor. It is also used to study the mechanism of RNA hydrolysis by providing a stable analog of the transition state. Its activity is not typically evaluated on whole cells, as it is a nucleotide analog that may have multiple effects.
|
| ln Vivo |
No specific in vivo activity data is reported. As a nucleotide analog, it could potentially interfere with cellular nucleic acid metabolism if administered in vivo. It shows promise in research for the treatment of cancer and viral infections, but this is at the stage of in vitro research only. No approved or widely studied in vivo animal models are documented for this compound.
|
| Enzyme Assay |
The standard assay for RNase A is performed in a 96-well plate. The reaction mixture (100 uL) contains 50 mM Tris-HCl (pH 7.5), 0.1 mg/mL BSA, and a fluorogenic RNA substrate (e.g., 0.5 uM of an RNAseAlert Substrate). 2',3'-cUMP is added at varying concentrations (0-1 mM). The reaction is initiated by adding 0.1-1 nM of RNase A. The increase in fluorescence (e.g., Ex/Em 490/520 nm) is measured over 15-60 minutes to determine the initial reaction rate. The Ki is calculated by fitting the data to a competitive inhibition model.
|
| Cell Assay |
2',3'-cUMP is a cell-permeable nucleotide analog, but it is not typically used in standard cell-based viability assays. For research, it could be added to the culture media of cancer cells at concentrations of 10-100 uM. After 24-72 hours, the effect on cell growth would be measured by MTT assay. However, its effect may be indirect, through inhibition of cellular RNases, and such uses are not standard. It can also be used as a standard in HPLC to quantify cyclic nucleotides in biological extracts.
|
| Animal Protocol |
No standard in vivo protocols exist for 2',3'-cUMP. As a potential anti-cancer lead, a xenograft mouse model could be used. The compound would be formulated in PBS and administered intraperitoneally or intravenously at a dose of 10-50 mg/kg. Tumor volume would be measured over 2-4 weeks, but such data is not available for this compound.
|
| ADME/Pharmacokinetics |
No specific pharmacokinetic data is available for 2',3'-cUMP sodium. As a sodium salt, it is water-soluble and soluble in DMSO. The compound is a cyclic phosphate, which is more stable than linear phosphates but can still be hydrolyzed by phosphodiesterases. For research, the compound is stored as a powder at -20degC, and solutions are prepared fresh in water or buffer. Its stability in plasma is unknown.
|
| Toxicity/Toxicokinetics |
No specific toxicology data is available. As a modified nucleotide, it is not expected to be highly toxic, but standard laboratory safety precautions should be followed. The compound may be a skin, eye, and respiratory tract irritant. Avoid inhalation, ingestion, and skin contact. It is strictly for research use only and not for human or veterinary use.
