12]. Moreover, preclinical studies have shown controversial evidence on sodium benzoate pharmacodynamic mechanism, testifying as the drug antipsychotic impact could possibly be accomplished in a murine PCP model of schizophrenia even without escalating D-serine levels [313]. Other much more selective DAO inhibitory drugs are currently tested in individuals with schizophrenia and among these, luvadaxistat has shown a promising improvement in cognitive functions [31416]. Hence, future studies exploring the tolerability and efficacy profile in distinct illness subgroups, also or to not other drugs enhancing the D-amino acid pathway, will shed light around the real possible of DAO inhibitors in schizophrenia and other psychotic disorders.Biomolecules 2022, 12,20 ofTable 2.
