Branched adamantyl and noradamantyl aryl-and aralkylpiperazines with serotonin 5-HT1A activity

   
   

This invention provides compounds and methods using them to provide neuroprotection and prevent or limit processes of neurodegeneration in mammals, including Alzheimer's Disease, Huntington's Disease, Parkinson's Disease, AIDS dementia, retinal disease, diabetic peripheral neuropathy, multiple sclerosis, stroke, acute thromboembolic stroke, focal ischemia, global ischemia, transient ischemic attack, ischemia resulting from surgery, head trauma, spinal trauma, hypoxia, fetal hypoxia, and neuroprotection. The compounds having the structure: ##STR1## wherein X is --CH.sub.2 -- or a bond; Y is --(CH.sub.2).sub.m -- or --(CH.sub.2)--O--(CH.sub.2)--; m 0 or 1; n is 0 or 1; R.sub.1 and R.sub.2 are independently selected from optionally substituted aryl or heteroaryl; the optical isomers and the pharmaceutically acceptable salts thereof.

Esta invenção fornece compostos e métodos usando os fornecer o neuroprotection e impedi-los ou os processos do limite do neurodegeneration nos mamíferos, including a doença de Alzheimer, a doença de Huntington, a doença de Parkinson, o dementia do AIDS, a doença retinal, o neuropathy periférico diabetic, o sclerosis múltiplo, o curso, o curso thromboembolic agudo, o ischemia focal, o ischemia global, o ataque isquêmico transiente, o ischemia resultando da cirurgia, o trauma principal, o trauma spinal, o hypoxia, o hypoxia fetal, e o neuroprotection. Os compostos que têm a estrutura: ## do ## STR1 wherein X é -- CH.sub.2 -- ou uma ligação; Y é -- (CH.sub.2).sub.m -- ou -- (CH.sub.2) -- O -- (CH.sub.2) --; m 0 ou 1; n é 0 ou 1; R.sub.1 e R.sub.2 são selecionados independentemente do arilo ou do heteroaryl opcionalmente substituído; os isomers óticos e os sais pharmaceutically aceitáveis disso.
