  Inhibition of monoamine oxidase by 8-phenoxymethylcaffeine derivatives

  摘要：

  A recent study has reported that a series of 8-benzyloxycaffeines are potent and reversible inhibitors of both human monoamine oxidase (MAO) isoforms, MAO-A and -B. In an attempt to discover additional caffeine derivatives with potent MAO inhibitory activities, and to contribute to the known structure-activity relationships of MAO inhibition by caffeine derived compounds, the present study investigates the MAO inhibitory potencies of series of 8-phenoxymethylcaffeine and 8-[(phenylsulfanyl)methyl]caffeine derivatives. The results document that the 8-phenoxymethylcaffeine derivatives act as potent reversible inhibitors of MAO-B, with IC50 values ranging from 0.148 to 5.78 mu M. In contrast, the 8-[(phenylsulfanyl) methyl] caffeine derivatives were found to be weak inhibitors of MAO-B, with IC50 values ranging from 4.05 to 124 mu M. Neither the 8-phenoxymethylcaffeine nor the 8-[(phenylsulfanyl) methyl] caffeine derivatives exhibited high binding affinities for MAO-A. While less potent than the 8-benzyloxycaffeines as MAO-B inhibitors, this study concludes that 8-phenoxymethylcaffeines may act as useful leads for the design of MAO-B selective inhibitors. Such compounds may find application in the therapy of neurodegenerative disorders such as Parkinson's disease. Using molecular docking experiments, this study also proposes possible binding orientations of selected caffeine derivatives in the active sites of MAO-A and -B. (C) 2012 Elsevier Ltd.
