In this study, carbonyl reductase activity was estimated as the ability to reduce 4-benzoylpyridine to S(-)-α-phenyl-4-pyridylmethanol in the cytosolic fraction from pig heart (pig heart cytosol). The order of their inhibitory potencies for the enzyme activity was hexanophenone > valerophenone > heptanophenone > butyrophenone > propiophenone. The inhibitory potencies of acetophenone and nonanophenone were much lower. A significant relationship was observed between Vmax/Km values for the reduction of alkyl phenyl ketones and their inhibitory potencies for carbonyl reductase activity in pig heart cytosol. Furthermore, hexanophenone was a competitive inhibitor for the enzyme activity. These results indicate that several alkyl phenyl ketones including hexanophenone inhibit carbonyl reductase activity in pig heart cytosol, by acting as substrate inhibitors., http://informahealthcare.com/doi/abs/10.1080/14756360600954023}, pages = {105--109}, title = {Inhibition of carbonyl reductase activity in pig heart by alkyl phenyl ketones}, volume = {22}, year = {2007}, yomi = {イマムラ, ヨリシゲ and シマダ, ヒデアキ and イマムラ, ヨリシゲ and シマダ, ヒデアキ} }
