sentence: CHM-1 ( an inhibitor of BioA that was identified in biochemical screening of LOPAC library16 ) was utilized in the assay as a positive control and displayed 78.73 % inhibition of BioA activity at 100 μ g / mL and exhibited an IC value of 0.68 μ g / mL or 2.42 μ M.All the compounds that exhibited greater than 60 % inhibition at a concentration of 100 μ g / mL were subjected to dose-response studies for the determination of their IC values ( Table 1 ) .
