Regulation of glycine transporter 1 (GlyT1) activity is a currently investigated strategy in drug discovery for schizophrenia. This study developed a series of new 4-benzoylpiperidine derivatives as GlyT1 inhibitors by bioisosteric replacement and mimicking of the pyridine ring of RG1678. Among the 4-benzoylpiperidine derivatives, 23q showed an IC50 of 30 nM. Preliminary optimization of the blood-brain barrier penetration led to the discovery of 3-(piperidin-4-yl)benzo[d]isoxazole derivatives. Both series showed good selectivity over GlyT2, D1, D2, D3, 5-HT1A and 5-HT2A receptors. Moreover, behavioral testing showed 23q (40 mg kg-1, intragastric) can inhibit the hyperlocomotion induced by acute treatment of phencyclidine, and improve the impaired negative and cognitive symptoms in chronic phencyclidine-induced C57BL/6J mice. An interesting finding showed that 3-(piperidin-4-yl)benzo[d]isoxazole was a privileged scaffold of atypical antipsychotic agents but exhibited high selectivity and potency as a GlyT1 inhibitor.

The GlyT1 transporter has emerged as a key novel target for the treatment of schizophrenia. Herein, we report on the optimization of the 2-alkoxy-5-methylsulfonebenzoylpiperazine class of GlyT1 inhibitors to improve hERG channel selectivity and brain penetration. This effort culminated in the discovery of compound 10a (RG1678), the first potent and selective GlyT1 inhibitor to have a beneficial effect in schizophrenic patients in a phase II clinical trial.
