As a partial agonist at the glycine site of the NMDA receptor, D-cycloserine (DCS) has been viewed as lacking potency to fully test the NMDA receptor hypofunction theory of schizophrenia. However, findings of full agonist activity at a subset of NMDA receptors that may have particular relevance to schizophrenia, plus a growing body of evidence demonstrating enhancement of learning and neuroplasticity in animal models, suggest novel therapeutic strategies with DCS in schizophrenia. Preliminary studies with once-weekly administration have supported this potential new role for DCS in schizophrenia by demonstrating benefit for negative symptoms, memory consolidation, and facilitation of cognitive behavioral therapy for delusions.
作为 NMDA 受体甘氨酸位点的部分激动剂,D-环丝氨酸(DCS)被认为缺乏效力来充分检验精神分裂症的 NMDA 受体功能低下理论。然而,在一组可能与精神分裂症特别相关的 NMDA 受体上发现了完全激动剂活性,加上越来越多的证据表明在动物模型中增强学习和神经可塑性,这表明 DCS 在精神分裂症中有新的治疗策略。每周一次给药的初步研究支持了 DCS 在精神分裂症中的这一潜在新作用,表明它对阴性症状、记忆巩固和促进妄想的认知行为疗法有益。
