Introduction: D-amino-acid oxidase (DAAO) degrades D-serine, a co-agonist of the NMDA receptor whose dysfunction is involved in the positive, negative, and cognitive symptoms of schizophrenia. The inhibition of DAAO appears to be a viable strategy to increase D-serine level and to have therapeutic potential in schizophrenia. Areas covered: This review describes the efforts to develop DAAO inhibitors and to optimize their in vitro and in vivo effects in preclinical settings. The structural evolution of DAAO inhibitors is presented from simple carboxylic acid derivatives via small, planar compounds with carboxylic acid mimetics to extended compounds whose binding is possible owing to DAAO flexibility. Inhibitory potency and pharmacokinetic properties are discussed in the context of compounds' ability to increase D-serine level and to show efficacy in animal models of schizophrenia. Expert opinion: The accumulated knowledge on the structural requirements of DAAO inhibitors and on their in vitro and in vivo effects provides appropriate basis to develop inhibitors with optimized potency, selectivity and pharmacokinetic profile including blood-brain penetration. In addition, the validation of DAAO inhibition therapy in alleviating the symptoms of schizophrenia requires further studies on the efficacy of DAAO inhibitors in behavioral assays of animals and on the species differences in D-serine metabolism.
