Este método representa o primeiro emprego de tiossemicarbazonas como componente eletrofílico em reações de síntese de guanidinas mediadas por tiófilo, onde a introdução de cada substituinte dos nitrogênios das guanil-hidrazonas ocorreu de forma regiosseletiva. As atividades antibacteriana e antifúngica foram avaliadas e alguns derivados mostraram atividade em valores pequenos de concentração inibitória mínima e com amplo espectro de atividade. Estudou-se a estrutura cristalina de duas guanil-hidrazonas, determinando-se suas configurações e, as únicas interações relevantes observadas foram intermoleculares do tipo N-H...N e C-H...N.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-21T15:23:52Z No. of bitstreams: 1 v20n4a06.pdf: 1247918 bytes, checksum: 64ea12a53a1e11439c127e54a5c6ad40 (MD5)Made available in DSpace on 2011-12-21T15:23:52Z (GMT).
