The present invention relates to a compound of formula I
wherein
R1, R2 and R3 are each independently hydrogen, lower alkyl, lower alkoxy, cycloalkyl, lower alkyl substituted by halogen or S-lower alkyl;
or to a pharmaceutically acceptable acid addition salt, racemic mixture, or corresponding enantiomer and/or optical isomer thereof. The compounds of formula I are good inhibitors of the glycine transporter 1 (GlyT-1), and have a good selectivity to glycine transporter 2 (GlyT-2) inhibitors. The compounds can be used in the treatment of neurological and neuropsychiatric disorders.
本发明涉及公式I的化合物,其中R1、R2和R3各自独立地为氢、较低的烷基、较低的烷氧基、环烷基、被卤素或S-较低烷基取代的较低烷基;或其药学上可接受的酸加成盐、外消旋混合物或相应的对映体和/或光学异构体。公式I的化合物是甘氨酸转运体1(GlyT-1)的良好抑制剂,并且对甘氨酸转运体2(GlyT-2)抑制剂具有良好的选择性。这些化合物可用于治疗神经和神经精神障碍。
