Based on 5 publication(s) in Google Scholar
EIDD-2749 (4'-Fluorouridine) is an orally active RdRp inhibitor. EIDD-2749 effectively blocks the replication of RSV and SARS-CoV-2. EIDD-2749 also exhibits activity against HCV and lymphocytic choriomeningitis virus (LCMV). EIDD-2749 is a promising oral therapeutic candidate for COVID-19 and is also suitable for research on other RNA viruses.

Biological Activity
EIDD-2749 induces a delayed stalling of phosphodiester bond formation by RSV and SARS-CoV-2 RdRP[1].
EIDD-2749 is rapidly anabolizes, metabolically stable, and potently antiviral in disease-relevant well-differentiated HAE cultures[1].
EIDD-2749 shows a ≥17-fold increase in anti-RSV potency relative to that on HEp-2 cells; however, the low cytotoxicity levels remains unchanged (CC50 169 mM), resulting in a high SI (SI = EC50/CC50) of ≥1877[1].
EIDD-2749 inhibits SARS-CoV-2 with an EC50 value of 0.2-0.6 M[2].
EIDD-2749 has an EC50 of 1.86 μM in theVero E6 cell line, cytotoxicity with a CC50 of 380 μM, and stability in human plasma[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
EIDD-2749 shows high efficacious to SARS-CoV-2 infection and is effective with a single daily dose versus molnupiravir administered twice daily in vivo[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.54 mM); Clear solution
