Biological Activity

제품 설명

SB-140 is a selective, covalent PLpro inhibitor with an IC₅₀ of ≤2.5 nM against SARS-CoV-2 PLpro. SB-140 has antiviral activity against SARS-CoV-2, MERS-CoV and SARS-CoV-1^[1].

In Vitro

SB-140 (15 min) potently inhibits purified SARS-CoV-2 PLpro with an IC₅₀ ≤ 2.5 nM^[1].
SB-140 (1 μM) exhibits high selectivity, with no inhibitory activity detected against 47 human DUBs and 9 cysteine proteases at a concentration of 1 μM^[1].
SB-140 (0-10 μM; 1 h) potently inhibits SARS-CoV-2 replication in A549-ACE2 cells, with an EC₅₀ of 0.3 nM and an EC₉₀ of 3 nM^[1].
SB-140 (0.01-100 μM) exhibits attenuated inhibitory activity against MERS-CoV replication in A549-ACE2 cells, with an EC₅₀ of 1.17 μM^[1].
SB-140 (0-1 μM) inhibits SARS-CoV-1 in A549-ACE2 cells, with an EC₅₀ of 14.1 nM^[1].

In Vivo

SB-140 (10 mg/kg; i.p.; twice daily; 5 days) reduces lung viral load by 15-fold in K18-hACE2 mice infected with SARS-CoV-2 variant β^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
