CRS3123
Based on 1 publication(s) in Google Scholar
CRS3123 (REP-3123) is an orally active antibacterial agent that targets methionyl-tRNA synthetase (MetRS). CRS3123 competitively displaces methionine from the active site of MetRS, preventing tRNA charging and protein synthesis, and exhibits greater selectivity for C. difficile MetRS than for human MetRS and Gram-negative bacterial MetRS. CRS3123 can be used in research on Clostridioides difficile infection and vancomycin-resistant enterococcal infection.

体外実験
CRS3123 (MIC <0.007-0.031 μg/mL) shows MIC <0.007 μg/mL against most enterococci isolates, including VRE, except E. faecalis HM-335 (0.031 μg/mL)[1].
CRS3123 (5-10× MIC; 24 h) is bacteriostatic against E. faecium NR-31909[1].
CRS3123 (10 days) maintains low resistance development in E. faecalis ATCC 29212 and E. faecium NR-31909 over 10 serial passages, with only 4-16-fold MIC increases[1].
CRS3123 (0.5-1 μg/mL) inhibits C. difficile, including B1/NAP1/027 strains, with an MIC90 of 1 μg/mL[2].
CRS3123 inhibits C. difficile toxin production[2].

Cell Line:Vero cells (monkey kidney epithelial cells)
-
Concentration:16 µg/mL (no toxicity); 32 µg/mL (20% cytotoxicity)
-
Incubation Time:24 h; 4 h (MTS/PMS)
-
Result:Demonstrated no toxicity up to 16 µg/mL but exhibited 20% cytotoxicity at 32 µg/mL, indicating mild toxicity at this concentration.
Based on the IC50-to-MIC50 comparison, CRS3123 had a ratio of >4571.

体内:
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.
