Abstract
PROCESSO DE RADIOMARCAçãO DE FLAVONóIDES E SUA APLICAçãO EM DIAGNóSTICO IN VIVO DE DISFUNçõES CEREBRAIS RELACIONADAS AOS SìTIOS RECEPTORES BENZODIAZEPìNICOS. Compreende um estudo referente ao desenvolvimento radioquímico de flavonóides radiomarcados e aplicação in vivo como agentes de imageamento cerebral frente a sítios receptores benzodiazepínicos, utilizando-se técnicas tomográficas, em dito processo foi estudada a marcação de flavonóides via substituição eletrofilica aromática e biodistribuição de flavona radiomarcada em camungongos Swiss. Os resultados indicam elevada concentração do radiotraçador no cérebro, principalmente até 30 minutos após a injeção do radiocomposto, compatíveis com a utilização clínica como agente de imageamento e com grande potencial para aplicação em medicina nuclear diagnóstica.
