Fig. (7). Chemical Structures of Three TEV Inhibitor Compounds Three compounds found in the LOPAC¹²⁸⁰ library screen as TEV inhibitors were confirmed using both the CP₂₃₄-Luc/ENLYFQC assay and the protein fusion cleavage assay. Their chemical structures are: A. aurintricarboxylic acid (ATA), B. 8,8'-[carbonylbis(imino-3,1-phenylenecarbonylimino)]bis(1,3,5-naphthalene-trisulfonic acid) hexasodium salt (NF-023), C. 4-[3-(4-Acetyl-3-hydroxy-2-propylphenoxy)propoxy]phenoxyacetic acid (L-165,041).
