The present invention relates to a compound of general formula I-A or I-B wherein X is a bond or a CH2- group; R1, R2 and R3 are independently from each other hydrogen, lower alkoxy, lower alkyl substituted by halogen or S-lower alkyl; or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer thereof. It has been found that the compounds of general formulas I-A and I-B are good inhibitors of the glycine transporter 1 (GlyT-1), and that they have a good selectivity to glycine transporter 2 (GlyT-2) inhibitors, suitable in the treatment of neurological and neuropsychiatric disorders.
本发明涉及一种一般式I-A或I-B的化合物,其中X是键或CH2-基团;R1、R2和R3分别独立地是氢、较低的烷氧基、受卤素取代的较低烷基或S-较低烷基;或者是药用酸盐、消旋混合物,或其对应的对映体和/或光学异构体。已经发现一般式I-A和I-B的化合物是甘氨酸转运蛋白1(GlyT-1)的良好抑制剂,并且它们对甘氨酸转运蛋白2(GlyT-2)抑制剂具有良好的选择性,适用于治疗神经和神经精神障碍。
