Gallinamide A TFA
Based on 1 Customer Validation
Gallinamide A TFA is a linearly depositing peptide and a potent inhibitor of cathepsin L (CatL) (IC50: 17.6 pM). Gallinamide A TFA inhibits SARS-CoV-2 infection by inhibiting CatL (EC50: 28 nM). Gallinamide A TFA also inhibits Plasmodium falciparum (IC50: 50 nM).

Biological Activity
IC50: 17.6 pM (Cathepsin L); 7.34 nM (Cathepsin B); 697 nM (Cathepsin V); 79.6 nM (Cathepsin K); 367 pM (Cathepsin S)[1]
EC50: 28 nM (SARS-CoV-2)[1]
IC50: 50 nM (P. falciparum)[2]
Gallinamide A TFA has low cytotoxicity with CC50 >100 μM in VeroE6 cells. Gallinamide A TFA (0.5 μM; 96 h) can inhibit CatL-mediated SARS-CoV-2 endosome entry into VeroE6 cells[1].
Gallinamide A TFA also mesylate with the TMPRSS2 inhibitor Nafamostat (HY-B0190A) exhibits synergistic effects. Potent antiviral activity in HEK-ACE2-TMPRSS2 cells, but ineffective in VeroE6 cell line[1].
