Biological Activity
SARS-CoV-2 3CLpro-IN-19 (Compound C5a), a non-covalent, non-peptide inhibitor of the SARS-CoV-2 3CLpro enzyme, exhibits potent in vitro activity with an IC50 of 0.7 uM. It demonstrates broad-spectrum efficacy against infection by Omicron subvariants (BA.5, BQ.1.1, and XBB.1.5) in human cells, with EC50 values ranging from 30-69 nM (1).
Target(s): SARS-CoV
Signaling pathway(s): Microbiology/Virology
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Determining the amount based on solution clarity.1. If the prepared solution is clear, it can be prepared in a larger amount for one-time use and stored at 4°C. It is recommended to prepare the solution once a week, as prolonged storage may lead to loss of efficacy. 2. If the prepared solution is a suspension, it is recommended to prepare and use immediately each time.
If you are using DMSO for preparation,sterilization is not recommended, as DMSO itself possesses strong sterilizing properties. The prepared solution is sterile. For further assurance, it can be left overnight at 4°C. The safest method is to filter through a specialized organic filter membrane. If water is used for preparation,sterilization can be achieved by filtering through a 0.22 μm filter membrane.
