    • NMDA receptor blockers, including pH-sensitive NMDA receptor blockers, are provided as neuroprotective 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, chronic pain, vascular dementia and glioma tumors. 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. Preferably the compounds provided herein are allosteric NMDA inhibitors.
    • 提供NMDA受体阻滞剂,包括pH敏感的NMDA受体阻断剂,作为神经保护药物,其可用于中风,创伤性脑损伤,癫痫和涉及脑或脊髓组织酸化的其它神经系统事件。 本发明的组合物和方法用于治疗由NMDA受体活化引起的神经变性。 本文所述的化合物由于病理状况如中风,外伤性脑损伤,心脏手术期间可能发生的全身缺血,呼吸停止后可能发生的缺氧等病理状况,具有低于正常pH值的脑组织中的活性增强, 癫痫,脊髓创伤,癫痫,慢性疼痛,血管性痴呆和神经胶质瘤。 本文所述的化合物还可用于预防帕金森氏老年痴呆症,亨廷顿舞蹈症,ALS患者和本领域已知的对NMDA受体阻断剂治疗有反应的其它神经变性病症患者的神经变性。 优选地,本文提供的化合物是变构NMDA抑制剂。
