WebIn conclusion, this study shows that C5-substituted 2-acetylphenol analogs are highly potent MAO-B inhibitors with seven compounds (of 17) exhibiting IC 50 values <0.01 μM. The 2-acetylphenol analogs also are selective for the MAO-B isoform as exemplified by compounds 2d, 2f, and 3b, which possess SI values >9,550. WebTable 5-7 points out that the inhibitor formulation (phenol + Zn2+) offers 99.5 % BE in the absence of the biocide and 50 ppm of CTAB [17] is needed to achieve 99.9 % biocidal efficiency (BE) in the absence of inhibitor formulation. However, in the presence of the inhibitor formulation 100 % BE is achieved with 10 ppm of CTAB itself.
