Medchemexpress LLC Robenidine hydrochloride | 25875-50-7 | 98.5% | 100 MG
Robenidine hydrochloride is an agent that primarily exhibits anticoccidial properties. It also demonstrates activity against certain bacterial strains, specifically MRSA and VRE, with respective MIC50 values of 8.1 μM and 4.7 μM. This compound has been observed to have a bactericidal effect on all tested S. aureus strains, with MBC/MIC90 ratios at or below 2. The presence of serum can significantly influence its effectiveness, showing a four-fold decrease in MIC values at 2% serum and no activity at 50% serum. Research has also indicated its influence on the pharmacokinetics of other compounds, such as florfenicol, by affecting elimination half-life, area under the curve, and mean residence time in studies.
- Exhibits anticoccidial activity.
- Active against MRSA and VRE bacterial strains.
- Bactericidal against S. aureus strains.
- Available as a solid, white to off-white in appearance.
- Purity of 98.5%.
