Antcin B

Cat. No.: HY-N15365: FAQs
Data Sheet Handling Instructions Technical Support

Antcin B is a SARS-CoV-2 3-chymotrypsin-like protease (3CL Pro) inhibitor. Antcin B binds to multiple key amino acid residues of 3CL Pro(such as Leu141, Asn142, Glu166, His163, etc.) through hydrogen bonds, salt bridges, and hydrophobic interactions, thereby inhibiting the activity of 3CL Pro, blocking the cleavage process of viral polyproteins, and suppressing the replication of the SARS-CoV-2 virus in host cells. Antcin B is promising for research of COVID-19.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
