| pubmed-article:15469019 | pubmed:abstractText | The linoleyl alcohol oxidation catalyzed by potato tuber 5-lipoxygenase was found to be efficiently inhibited by stable nitroxyl radicals: 1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl 1-bicyclo[2,2,2]octane-1-carboxylate, 1-adamantylacetate, dodecanoate, and octadecanoate. The dependence of apparent IC50 values on the rotational correlation times of times of 4-hydroxy-1-oxyl-2,2,6,6-tetramethylpiperidine and its derivatives in model micellar systems was analyzed. The inhibition mechanism was proposed; it involves the interaction of hydrophobic nitroxyl radical with the intermediate radical enzyme-substrate complex. | lld:pubmed |
