Biological Activity
IC50: 1.47 µM (SARS-CoV-2-S-RBD binding to ACE2); 2.63 µM (SARS-CoV-S1S2 binding to ACE2); 2.11 µM (TNF-R1-TNFα binding)[1]
Direct Violet 1 inhibits SARS-CoV-2-S-RBD binding to human ACE2, inhibits SARS-CoV-S1S2 binding to ACE2, and inhibits TNF-R1 binding to TNFα with IC50 values of 1.47 μM, 2.63 μM, and 2.11 μM, respectively[1].
Direct Violet 1 inhibits SARS-CoV-2 pseudovirus entry into hACE2 expressing host cells in a concentration-dependent manner with an IC50 of 35.8 μM[1].
