Resumo: Núcleos imidazólicos estão presentes nas estruturas de muitas substâncias com atividades farmacológicas, para diferentes finalidades. O 6,6-dimetil-3,4,5,6-tetra-hidrobenzo-[7,8]cromeno[5,6-d]imidazol (BLI-H) é um naftoimidazol obtido a partir da β-lapachona – uma naftoquinona encontrada em espécies da família das bignoniáceas e que também pode ser obtida sinteticamente.1 O interesse nos estudos com este naftoimidazol se refere às possibilidades sintéticas para o núcleo imidazólico desta molécula, não substituído nas posições 1, 2 e 3, capaz de sofrer reações de substituições nucleofílica alifática e/ou eletrofílica aromática. Além disso, este, que é o naftoimidazol mais simples que pode ser obtido a partir da β-lapachona, já demonstrou seu potencial na atividade antitripanossômica, embora não tão expressiva quanto as de outros naftoimidazóis, substituídos, derivados de β-lapachona. Este trabalho relata a preparação de uma série de compostos obtidos por alquilação de BLI-H e a atividade inibitória significativa destes compostos sobre o crescimento de Staphylococcus aureus resistente à meticilina, Escherischia colii, Cryptococcus neoformans, Candida albicans, assim como Trypasoma cruzi. Além dos produtos das N-alquilações, a busca por derivados com diferentes substituintes no carbono 2, levou à síntese de três novos naftoimidazóis com grupos acila, bromo e amina, respectivamente, neste carbono

O 6,6-dimetil-3,4,5,6-tetra-hidrobenzo-[7,8]cromeno[5,6-d]imidazol (BLI-H) é um naftoimidazol obtido a partir da β-lapachona – uma naftoquinona encontrada em espécies da família das bignoniáceas e que também pode ser obtida sinteticamente.1 O interesse nos estudos com este naftoimidazol se refere às possibilidades sintéticas para o núcleo imidazólico desta molécula, não substituído nas posições 1, 2 e 3, capaz de sofrer reações de substituições nucleofílica alifática e/ou eletrofílica aromática.

The interest in studies with this naftoimidazole refers to synthetic possibilities for the imidazole ring of this molecule unsubstituted at positions 1,2 and 3, capable of undergoing nucleophilic substitution reactions with aliphatic and / or aromatic electrophiles. Furthermore, this which is the simplest naftoimidazole which can be obtained from β-lapachone, has shown antitripanosomal activity, although not as significant as some aryl-substituted β-lapachone derived naphthoimidazoles. This work reports the preparation of a series of compounds obtained by alkylation of BLI-H and the significant inhibitory activity on the growth of methicillin-resistant Staphylococcus aureus, Cryptococcus neoformans, Escherischia colii, Candida albicans, as well as Trypanosoma cruzi, achieved with these compounds. In addition to the products of alkylations, the search for derivatives with different substituents at carbon 2, led to the synthesis of two new β-lapachone-derived naphthoimidazoles with acyl, amine and bromine groups respectively, in that carbonapplication/pdfporUniversidade Federal Rural do Rio de JaneiroPrograma de Pós-Graduação em QuímicaUFRRJBrasilInstituto de Ciências ExatasN-alkylnaftoimidazoles2-acylnaftoimidazole2-amine-naftoimidazolesN-alquil-naftoimidazóis2-acil-naftoimidazóis2-amino-naftoimidazóisQuímicaSíntese de naftoimidazóis derivados de β-lapachona com potenciais atividades biológicasSynthesis of β-lapachone-derived naphthoimidazoles with potential biological activitiesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis1.

description Núcleos imidazólicos estão presentes nas estruturas de muitas substâncias com atividades farmacológicas, para diferentes finalidades. O 6,6-dimetil-3,4,5,6-tetra-hidrobenzo-[7,8]cromeno[5,6-d]imidazol (BLI-H) é um naftoimidazol obtido a partir da β-lapachona – uma naftoquinona encontrada em espécies da família das bignoniáceas e que também pode ser obtida sinteticamente.1 O interesse nos estudos com este naftoimidazol se refere às possibilidades sintéticas para o núcleo imidazólico desta molécula, não substituído nas posições 1, 2 e 3, capaz de sofrer reações de substituições nucleofílica alifática e/ou eletrofílica aromática. Além disso, este, que é o naftoimidazol mais simples que pode ser obtido a partir da β-lapachona, já demonstrou seu potencial na atividade antitripanossômica, embora não tão expressiva quanto as de outros naftoimidazóis, substituídos, derivados de β-lapachona. Este trabalho relata a preparação de uma série de compostos obtidos por alquilação de BLI-H e a atividade inibitória significativa destes compostos sobre o crescimento de Staphylococcus aureus resistente à meticilina, Escherischia colii, Cryptococcus neoformans, Candida albicans, assim como Trypasoma cruzi. Além dos produtos das N-alquilações, a busca por derivados com diferentes substituintes no carbono 2, levou à síntese de três novos naftoimidazóis com grupos acila, bromo e amina, respectivamente, neste carbono
