Sobre IBD

As pirimidinas são compostos de anéis heterocíclicos com 6 membros, compostos por azoto e carbono. Estão presentes em toda a natureza sob várias formas e são os blocos de construção de numerosos compostos naturais, desde antibióticos a vitaminas e lipossacarídeos. As pirimidinas mais frequentemente reconhecidas são as bases do ARN e do ADN, sendo as mais abundantes a citosina, a timina ou o uracilo. A origem do termo pirimidina remonta a 1884, quando Pinner cunhou o termo a partir de uma combinação das palavras piridina e amidina, devido à semelhança estrutural com esses compostos. Desde estas investigações iniciais, centenas de compostos contendo pirimidina foram encontrados em bioquímica. As numerosas modificações deste arcabouço e a sua importância relativa na natureza fazem dele uma área de estudo interessante.
