2-amino-4,5-methyleneadipic acid compounds for treatment of CNS disorders.

摘要

Compounds, compositions and methods are described for treating a CNS disorder such as a cognitive disorder, epilepsy, depression, Parkinson's disease, Alzheimer's disease, a neurodegenerative disease or neurotoxic injury. Compound of interest are 2-amino-4,5-methyleneadipic acid compounds and derivatives defined by the formula I: <CHEM> wherein R<1> is selected from hydrido, alkyl, cycloalkyl, aralkyl, aryloxyalkyl, arylthioalkyl, <CHEM> with each of R<2>, R<3>, R<4> and R<5> being independently selected from hydrido, alkyl, cycloalkyl, aryl and aralkyl; wherein each of X and Y is independently selected from hydroxyl, alkoxy, alkylthio, amino and <CHEM> with each of R<6> and R<7> being independently selected from hydrido, alkyl, cycloalkyl, aryl and aralkyl; wherein any of R<1> through R<7> groups having a substitutable position may be substituted with one or more substituents selected from hydroxyl, halo, alkyl, haloalkyl, cyano, alkoxy, alkylthio, sulfinyl, sulfonyl, sulfinylalkyl, sulfonylalkyl, amino, acyl, acyloxy, alkoxycarbonyl and aminocarbonyl; or a pharmaceutically-acceptable salt thereof. The 2R,4S,5S isomers and the 2R,4R,5R isomers of these compounds are preferred.
