| Outline of Final Research Achievements |
Recently, widespread illegal drugs become social issues. Authentic standard of these metabolite are needed for analysis because these drugs are converted to metabolite by drug metabolizing enzymes (DMEs). In general, it is difficult or sometimes impossible to prepare the metabolites. Purpose of the present study is to prepare the metabolites of illegal drugs using heterologous expression system of DMEs in yeast.
Two monoamine oxidase (MAO) isoforms and five flavin-containing monooxygenase (FMO) isoforms were newly constructed using budding yeast cell. It was impossible to evaluate the activity of MAO or FMO toward illegal drugs because suitable substrate was not commercially available by legal restriction. We next tried to prepare the multiple metabolites from MDMA or MDA using expression system of CYP, COMT and UGT, which was established in previously. However, it was impossible to prepare the metabolites because first metabolic reaction by CYP was not occurred.
