NMDA receptor blockers, including pH-sensitive NMDA receptor blockers, are provided as neurprotective drugs that are useful in stroke, traumatic brain injury, epilepsy, and other neurologic events that involve acidification of brain or spinal cord tissue. Compositions and methods of this invention are used for treating neurodegeneration resulting from NMDA receptor activation. The compounds described herein have enhanced activity in brain tissue having lower than normal pH due to pathological conditions such as hypoxia resulting from stroke, traumatic brain injury, global ischemia that may occur during cardiac surgery, hypoxia that may occur following cessation of breathing, pre-eclampsia, spinal cord trauma, epilepsy, chrounic pain, vascular dementia and glioma rumors. Compounds described herein are also useful in preventing neurodegeneration in patients with Parkinson's Alzheimer's, Huntington's chorea, ALS, and other neurodegenerative conditions known to the art to be responsive to treatment using NMDA receptor blockers. Prefebably the compounds provided herein are allosteric NMDA inhibitors.
NMDA受体阻滞剂,包括pH敏感的NMDA受体阻滞剂,作为神经保护药物提供,可用于中风、创伤性脑损伤、癫痫和其他涉及脑或脊髓组织酸化的神经事件。本发明的组合物和方法用于治疗由NMDA受体激活引起的神经退行性疾病。所述化合物在具有低于正常pH的脑组织中具有增强的活性,这是由于病理情况(如中风、创伤性脑损伤、可能发生于心脏手术期间的全球性缺血、呼吸停止后可能发生的低氧、先兆子痫、脊髓损伤、癫痫、慢性疼痛、血管性痴呆和胶质瘤)所致。所述化合物还可用于预防帕金森病、阿尔茨海默病、亨廷顿舞蹈症、肌萎缩侧索硬化症和其他已知对使用NMDA受体阻滞剂治疗有响应的神经退行性疾病患者的神经退行性。最好所提供的化合物是变构的NMDA抑制剂。
