Estrutura, reatividade e propriedades biológicas de hidantoínas

Abstract: Recebido em 27/9/06; aceito em 10/8/07; publicado na web em 19/3/08 STRUCTURE, REACTIVITY AND BIOLOGICAL PROPERTIES OF HIDANTOINES. Hydantoin (imidazolidine-2,4-dione) is a 2,4-diketotetrahydroimidazole discovered by Baeyer in 1861. Thiohydantoins and derivatives were prepared, having chemical properties similar to the corresponding carbonyl compounds. Some biological activities (antimicrobial, anticonvulsant, schistosomicidal) are attributed to the chemical reactivity and consequent affinity of hydantoinic … Show more

“…The hydantoins (imidazolidin-2,4-dione) are interesting compounds due to their occurrence in nature, chemical reactivity (with consequent affinity for biomacromolecules) and numerous biological properties that are favorable for drug development. Structural changes in the imidazolidine ring of such compounds yields molecules with variety of pharmacological properties, including anti-inflammatory, antifungal, antibacterial, hypoglycemic, schistosomicides and anti-cancer activities, among others [11,12]. Therefore, the aim of this study was to evaluate the potential anti-inflammatory and antinociceptive activities of hybrid indole-imidazolidines molecules.…”

“…Many hidantoin derivatives have pharmacological activities (anticonvulsant 1 , antifungic 2 , antibacterial 2 and antiparasitic 2 ), related to the substituent in positions 3 or 5 of the imidazolidinic-like ring. In this work, several 3-substituted imidazolidinic-like compounds were synthesized from fenitoin, aiming at potential new drugs presenting more selectivity, security, less toxicity and lower cost on the treatment of ulcer, caused by Helicobacter pylori.…”

“…Ademais, as hidantoínas parecem ser os únicos agentes de ligação compatíveis com oxidantes como HMX (ciclotetrametileno tetranitramina) e RDX (ciclotrimetileno trinitramina), além de não apresentarem restrições quanto à estocagem (Dundar, 2005;Consaga, 1980). Dundar (2005) A hidantoína é um composto heterocíclico de cinco membros ( Fig.1) com fórmula molecular C 3 H 4 N 2 O 2 , que corresponde ao 2,4-di-ceto-tetra-hidro-imidazol, embora seja, também, denominada imidazolidina-2,4-diona (Oliveira, 2008). A hidantoína foi descoberta por Bayer, em 1861, em meio a um trabalho com ácido úrico (Finkbeiner, 1965).…”

“…A primeira fórmula estrutural para este composto foi sugerida por Kolbe em 1870, e modificada por Strecker, que propôs nova fórmula, até hoje aceita. Desde então, o núcleo hidantoínico e seus derivados tem sido estudados, tanto quanto às suas propriedades químicas, quanto biológicas, dada sua grande potencialidade como protótipo para o desenvolvimento de novos produtos, com diferentes aplicações (Oliveira, 2008).…”
