説明
It is of importance to determine whether antipsychotic drugs currently prescribed for schizophrenia exert D-amino acid oxidase (DAO)-inhibitory effects. We first investigated whether human (h)DAO can metabolize D-kynurenine (D-KYN) to produce the fluorescent compound kynurenic acid (KYNA) by using high-performance liquid chromatography with mass spectrometry, and fluorescence spectrometry. After confirmation of KYNA production from D-KYN by hDAO, 8 first- and second-generation antipsychotic drugs, and 6 drugs often prescribed concomitantly, were assayed for hDAO-inhibitory effects by using in vitro fluorometric methods with D-KYN as the substrate. DAO inhibitors 3-methylpyrazole-5-carboxylic acid and 4H-thieno[3,2-b]pyrrole-5-carboxylic acid inhibited KYNA production in a dose-dependent manner. Similarly, the second-generation antipsychotics blonanserin and risperidone were found to possess relatively strong hDAO-inhibitory effects in vitro (5.29 ± 0.47 μM and 4.70 ± 0.17 μM, respectively). With regard to blonanserin and risperidone, DAO-inhibitory effects should be taken into consideration in the context of their in vivo pharmacotherapeutic efficacy.
