Methods for delivering therapeutic amounts of glutamate to the CNS while simultaneously protecting against its excito-toxic effects are provided. By administering a blood-brain barrier-permeable Conjugate Compound, which comprises glutamate linked to an N-methyl-D-aspartate receptor antagonist, glutamate is released within the CNS for beneficial effect without causing excito-toxicity. Examples of such Conjugate Compounds are provided and their cognition-enhancing effect without engendering excito-toxicity in both normal and cognition-impaired animals is demonstrated.
本研究提供了向中枢神经系统输送治疗量谷
氨酸的方法,同时防止其兴奋毒性效应。通过施用可透过血脑屏障的共轭化合物(其中包括与
N-甲基-D-天冬氨酸受体拮抗剂相连的谷
氨酸),谷
氨酸可在中枢神经系统内释放,从而产生有益效果,同时不会导致兴奋毒性。本文提供了此类共轭化合物的实例,并证明了它们在正常动物和认知障碍动物中的认知增强效果,而不会产生兴奋毒性。
