title: New cyclic tetrapeptides from Nonomuraea sp. TA-0426 that inhibit glycine transporter type 1 (GlyT1).
abstract: In the course of our search for natural antipsychotic agents, we isolated five new cyclic tetrapeptides from the fermentation broth of Nonomuraea sp. TA-0426. These compounds turned out to be analogues of WSS2220, which had been produced by the same actinomycete and showed strong inhibitory activity against GlyT1. Four of the present peptides exhibit more potent GlyT1 inhibitory activities than WSS2220.
